Definitions
- the present invention relates to the use of a guide for the selective catheterization of anatomical structures and the placement of therapeutic instruments.
- the current guides are provided with a flexible end. Indeed, when the guide is confronted with one of these obstacles, he can be deflected and come to impact or touch the walls of the natural duct which can cause injury (edema) and / or deterioration of the guide making further navigation difficult.
- the dimensions of the guide particularly those of its distal end vis-à-vis the therapist, should allow navigation of the guide in very narrow ducts whose diameter is reduced as the progression of the guide in the natural ways to explore. Solutions have been proposed in the various documents of the state of the art such as the "Loop Tip Wire Guide" described in WO 2006/039217. However, the current solutions do not fully resolve these technical difficulties and therefore do not satisfy the therapists.
- the present invention makes it possible to navigate in a network of ducts whose diameter is reduced as and when the guide progresses in the routes to be explored.
- a guide for catheterization whose body is provided at its distal end with a protrusion or tip having a three-dimensional shape, preferably axisymmetric around the axis of revolution of said guide.
- This three-dimensional shape may for example be ovoid, spheroidal, ellipsoid.
- this form has no stop or acute angle and in particular has a profile perpendicular to the longitudinal axis which has a radius of curvature almost constant.
- quasi constant is meant a variation of between 50 to 200% and preferably between 75 and 125%.
- the guide is characterized in that the protrusion or tip has in the plane perpendicular to the longitudinal axis of said guide body at least one dimension greater than the diameter of said guide body.
- at least one dimension and preferably one dimension in a plane perpendicular to the longitudinal axis and in particular the maximum diameter of the protrusion is significantly greater than the diameter of the body of the guide.
- the protrusion has significantly larger dimensions than the body of the guide both radially and axially.
- the protuberance or the tip of the guide is detachable from the body of said guide. The separation may advantageously occur within the human body or animal, ie in situ and preferably on the site to be treated. For this purpose, provision is made for the presence of detaching means which will enable the therapist to detach or detach the protrusion or the tip of the body from said guide.
- Advantageously means of separation are provided to make the detachable protuberance of the guide within the human body or animal.
- This excrescence can of course also be detachable on the outside of the human body.
- the release of the protrusion of the guide can be done by the action of disengaging means already present on the guide.
- the disengagement of the outgrowth or the tip results from a voluntary action of the therapist and should in no case unfold impromptu.
- the separation is effected by a mechanical action on the order of the therapist.
- Control means of the uncoupling means may also be provided and advantageously allow to detach the protuberance or tip as soon as we reached the site to be treated.
- the entire protrusion or tip is detached from the guide so as to avoid the presence of abrasive or blunt portions that can act and injure the surrounding tissue.
- Fixing the protrusion or detachable tip on the guide is preferably carried out by physicochemical interactions.
- the attachment of the protrusion or the tip on the body of the guide is carried out using a substance having adhesive properties.
- connection between the protuberance or the tip and the body of the guide is chosen according to the physicochemical properties of the materials used for their respective manufacture.
- the material of the protrusion or tip of the guide is preferably deformable or expandable by deployment.
- the material of the protrusion or the tip of the guide is preferably elastic.
- the protuberance is not present on the guide before it is introduced into the human body, it only appears in the human body, for example by the action of an inflatable membrane.
- the material of the protrusion or tip of the guide may not be deformable, this is particularly the case if the tip is detachable.
- this protrusion may be made of metallic material, organic (for example polymer, elastomer), silica, ceramic or composite.
- the outgrowth should preferably be biocompatible (as for example described in standard EN
- the material in which this protrusion or this tip is made has a coefficient of thermal expansion greater than that of the material in which the guide is formed.
- This protrusion may be solid, hollow or traversed by one or more orifices. Its outer surface will preferably be treated to obtain a lower coefficient of friction than the anatomical environment and therefore have an improved roughness so as to allow and facilitate navigation.
- the protrusion can be made in the same materials as those used for the realization of the guide.
- the body of the guide is made using at least one of the following materials: cellulose acetate, cellulose nitrate, silicone, polyethylene, high density polyethylene, polyethylene teraphthalate, polyurethane, polybutylene fluoride, polyamide, polyester, polyorthoesther polyvinyl chloride, polypropylene, acrylonitrile butadiene styrene, polycarbonate, polyurethane, silicone nylon, polyanhydride or other equivalents.
- the protrusion or the tip is made using at least one of the following materials: cellulose acetate, cellulose nitrate, silicone, polyethylene, high density polyethylene, polyethylene teraphthalate, polyurethane, polybutyl fluorethylene, polyamide, polyester, polyorthoester, polyvinyl chloride, polypropylene, acrylonitrile butadiene styrene, polycarbonate, polyurethane, silicone nylon, polyanhydride or other equivalents.

- the present invention advantageously allows a single use of the guide for a catheter.
- the guide for catheterization is provided at its distal end with a protrusion or tip having a shape.
- a protrusion or tip having a shape.
- the guide is characterized in that the protrusion or tip has in the plane perpendicular to the longitudinal axis of said guide a dimension greater than the diameter of said guide.
- the protuberance or the tip of the guide is secured to the body of said guide.
- the protuberance or tip of the guide is detachable from the body of said guide.
- the material of the protrusion or tip of the guide is deformable.
- the material of the protuberance or tip of the guide is not deformable.
- Figures 1 to 4 each represent a preferred form of the protrusion present at the distal end of the guide. These growths have a three-dimensional shape and preferably axisymmetric around the axis of revolution of the body of the guide. At least one dimension and preferably one dimension in a plane perpendicular to the longitudinal axis and in particular a diameter and preferably the maximum diameter ( ⁇ 2) of the protrusion 10 is significantly greater than the diameter ( ⁇ i) of the body 1 of the guide .
- the protrusion significantly exceeds the body 1 of the guide both in the axial direction (L 2 ) and radial ( ⁇ 2).
- the dimension (maximum diameter ⁇ 2) of the protrusion significantly exceeds the diameter ( ⁇ i) of the body of the guide 1 in the sense that radial.
- the dimension in the axial direction corresponds essentially to the distal end of the guide body.
- the guide is curved, the axis of revolution of the protrusion is preferably the axis 100 of the guide when it is straightened (c that is to say in the non-curved position).
- the outgrowth is deformable or extensible allowing a change of shape and / or volume, allowing a transition from a non-deployed state to a deployed state or conversely, the deployed state being defined by the fact that at least one dimension and in particular a dimension perpendicular to the longitudinal axis and preferably the diameter ( ⁇ 2) of the outgrowth is significantly greater than the diameter ( ⁇ i) of the body of the guide while the unexpanded state corresponds to a state where the protrusion does not have a larger dimension in the plane perpendicular to the longitudinal axis, the maximum dimension and in particular the diameter of the body of the guide.
- the protrusion 10 is preferably constituted by an extensible or inflatable element 11 such as a membrane or a balloon that can be inflated by a gas or a fluid 12.
- the volume of the protrusion 10 is obtained for example by simple injection under pressure a fluid through an internal channel 2 present in the guide 1.
- the protrusion 10 is extensible or deformable. Extensible means a change in the volume of the outgrowth while deformable means a change in its shape.
- the protrusion can move from a deployed state to a non-deployed state by changing its shape and / or its volume.
- the deployed state being defined by the fact that at least one dimension and in particular a dimension perpendicular to the longitudinal axis of the guide body and preferably the maximum diameter of the protrusion is significantly greater than the diameter of the guide body while that the unexpanded state corresponds to a state where the protrusion does not have a dimension greater than the diameter of the body of the guide.
- the protrusion may be made of a shape memory material such as "Shape Memory Polymers” which will change their state or shape by raising the temperature of the ambient environment. This rise in temperature can simply occur through the application of external means such as electrical current or simply by the influence of body temperature.
- shape Memory Polymers such as "Shape Memory Polymers” which will change their state or shape by raising the temperature of the ambient environment. This rise in temperature can simply occur through the application of external means such as electrical current or simply by the influence of body temperature.
- Figures 7 show the means for detaching or dissociating the protuberance 10 or the tip (detachable) of the body of the guide 1.
- the various steps ( Figure 7a to 7c) necessary to detach the protrusion or the tip to the help of these means is represented.
- the uncoupling means shown in FIG. 7 consist for example of a catheter 4 which exerts pressure on the outer face of the protuberance 10 or the tip.
- the end of the catheter exerting this pressure comprises a ring or a ring ensuring a uniform distribution of the pressure on the protrusion or the tip.
- the presence of this ring increases the rigidity of the end of the catheter.
- Figures 8 show means for detaching or disengaging the protrusion 10 or the tip (detachable) of the guide body 1.
- the various steps (8a to 8c) necessary to unhook the protrusion or the tip to the help of these means is represented.
- the securing means shown in FIG. 8 consist of an internal channel or channel 6 present inside the guide body 1 and one of whose open ends coincides with the distal end, relative to the therapist, of the guide. This duct or channel 6 is used to convey from the proximal end, relative to the therapist, the guide fluid under pressure.
- This fluid will exert sufficient pressure on the inner face of the protrusion 10 or tip in such a way as to cause its integral separation of the guide 1.
- this fluid is a liquid.
- this fluid is gas.
- this liquid is water.
- this liquid is a saline buffer.
- a device comprising the two types of aforementioned means for detaching the protuberance or the detachable tip of the guide is another preferred embodiment. Examples:
- the selective catheterization of the bile duct through the Vater papilla is technically difficult and can be done either directly with a catheter or with the aid of a guide.
- the sphincter of Oddi is covered with a mucous membrane and, when the catheterization is not successful during the first maneuvers, the repeated manipulation of catheters or guide which impinges in the mucous membrane, creates an edema, making the procedure more difficult .
- the type of guide described above provided with a rounded and atraumatic end, having no angulation, reduces the trauma of the mucosa and the edema that results. Similarly, it helps the flexible end of the guide to adapt to the S shape of the disc, to find its way to the bile duct.
- Modified guides according to the present invention have been tested in animal models. These tests have revealed that this particular embodiment of the present invention can significantly reduce the tendency to impinge the distal end of the guide into complex structures.
- the protrusion is deliberately detached from the guide, inside the animals, by the action of the catheter on the guide.
- the protrusion used for this catheterization is a shape similar to that shown in Figure 2. This protrusion is detached from the body of the guide by the action of the means of uncoupling.
- the tested material constituting the outgrowth is the polyester. The dimensions of the growth for this test are:
- L 2 Height of the outgrowth.
- L 2 2.5 mm in this example.
- the selective catheterization of the pancreas is technically difficult and can be done either directly with a catheter or with the aid of a guide.
- the sphincter of Oddi is covered with a mucosa and, when the catheterization is not successful during the first maneuvers, the repeated manipulation of catheters or of guide which impacts in the mucous membrane, creates an edema, making the procedure more difficult.
- the type of guide described above provided with a rounded end atraumatic and having no angulation, reduces the trauma to the mucosa and edema that results. Similarly, it helps the flexible tip of the guide to fit the S shape of the disc, to find its way to the pancreas. Modified guides according to the present invention have been tested in animal models.
- the protrusion used for this catheterization is a spherical shape.
- the test material constituting the outgrowth is polyester. The dimensions of the growth for this test are:
