Definitions

  • the present invention relates to a catheter port assembly and a method of inserting
  • Catheters for extracorporeal blood purification may be located in various venous locations and cavities throughout the body of a patient for administration of solutes and for removal of toxins and fluids from the body via an extracorporeal blood circulation.
  • Such venous catheterization may be performed by using a single catheter having multiple lumens.
  • a typical example of a multiple lumen catheter is a dual lumen catheter in which one lumen serves to aspirate blood (arterial line) and the other lumen serves to restitute cleaned blood (venous line).
  • An example of such a dual lumen catheter assembly is the SPLIT CATH® catheter, manufactured by Medical Components, Inc. of Harleysville, Pennsylvania.
  • Catheterization may also be performed by using separate, single lumen catheters inserted through the same incision into the deep vein to be catheterized.
  • dual catheter assemblies are also manufactured by Medical Components, Inc. of Harleysville, Pennsylvania.
  • An example of a dual single lumen catheter assembly is the Tesio® catheter system, sold by Medical Components, Inc.
  • the vessel is identified by aspiration with a long hollow needle in accordance with the well known Seldinger technique.
  • a thin guide wire is then introduced, typically through the syringe needle or other introducer device into the interior of the vessel.
  • the introducer device is then removed, leaving the distal end portion of the guide wire that has been inserted into the vessel within the vessel and the opposing proximal end of the guide wire projecting beyond the surface of the skin of the patient.
  • several options are available to a physician for catheter placement.
  • the simplest option is to pass a semi-rigid catheter into the vessel directly over the guide wire.
  • the guide wire is then removed, leaving the catheter in position within the vessel.
  • a vein dilator device generally within a sheath, is passed over the guide wire to enlarge the guidewire entrance site and to facilitate the introduction of the catheter.
  • the guidewire and dilator are removed and the catheter is inserted through the sheath, into the vein.
  • the sheath is then removed, leaving the catheter in place.
  • the present invention discloses a catheter port assembly having a body having a distal end, a proximal end and a longitudinal channel extending therethrough between the distal end and the proximal end.

  • the proximal end 201 of the catheter lumen 200 is disposed around the distal portion of the body 101, as shown in Fig. 7.
  • the proximal end 201 of catheter lumen 200 is preferably disposed about the barbs 112 when disposed around the distal portion of the body 101.
  • the present embodiment shows a distal cover 170 that is slid over the lumen 200 prior to engaging the lumen 200 with the distal portion 110 of the assembly 100
  • the distal cover 170 may have some other configuration that allows the attachment of the distal cover 170 to the assembly at a time before or after said attachment occurs with the present embodiment.
  • the suture 220 is tied, and knotted in a knot 222, around the proximal end 201 of the catheter lumen 200.
  • the suture 220 is tied around the catheter lumen 200 at a position along the distal portion 110 of the body 101 between two barbs 112.
  • the catheter lumen 200 is further restricted from moving relative to the assembly 100 when the suture 220 is tightened around the catheter lumen 200, thereby squeezing the catheter lumen 200 around the distal portion 110 of the body 101.
  • the suture 220 is placed along the catheter lumen 200 and the distal cover 170 is slid proximally along the catheter lumen 200, over the suture 220, toward the body 101.
  • the distal cover 170 is slid proximally until the distal cover 170 engages the body 101, thereby covering the proximal end 201 of the catheter lumen 200 and the knot 202 of the suture 200.
  • the flats 184a of the distal cover 170 engage the flat sides 115a of the body 101.
  • the assemblies 100, 100' are then placed at least partially through the exit sites 14, 14' and into subcutaneous tunnels 16, 16'.
  • the assemblies 100, 100' are at least partially disposed within the exit sites 14, 14', preferably the retaining ridge 182, 182' of each assembly 100, 100' engages the flesh of the patient 10 so that the flesh of the patient 10 heals around the retaining ridge 182, thereby further securing the assemblies 100, 100' at least partially within the patient 10.
  • the catheter assemblies 100, 100' are pulled distally, back into the patient 10 until the assemblies 100, 100' are at least partially within the exit sites 14, 14'.
  • the assemblies 100, 100' at least partially plug the exit sites 14, 14' when pulled distally back into the patient 10. This is performed by pulling on the sutures 220, 220' at the entrance site 13.
  • the assemblies are pulled back into the patient to a point where the rounded indentation 183 is disposed at the skin level, leaving part of the rounded indentation 183 outside of the patient 10 and part of the rounded indentation 183 within the patient 10.
  • the retaining ridge 182 is disposed inside of the patient 10, thereby allowing the patient's 10 flesh to heal around the retaining ridge 182 and further restricting the movement of the assemblies 100, 100' relative to the patient 10.
  • the knot 222 of the suture 220 (shown in Fig. 7) is a first end of the sutures 220, 220' and second ends 224, 224' of the sutures 220, 220' are disposed near the entrance site 13 of the subcutaneous tunnels 16, 16' after the assemblies 100, 100' are tunneled.
  • the second ends 224, 224' of the sutures 220, 220' are knotted together in a second knot 210, located near the entrance site 13. Knotting the sutures 220, 220' together near the entrance site 13 serves to further secure the assemblies 100, 100' within the patient 10.
  • the assemblies 100, 100' are secured to each other using the bracket 190.
  • the bracket 190 engages the assemblies 100, 100' as discussed previously herein, although those skilled in the art will recognize that the bracket 190 may engage the assemblies 100, 100' in other ways without departing from the scope of the present invention.
  • the arterial assembly 100 is connected to the arterial blood line of an extracorporeal treatment device, such as a hemodialysis machine (not shown).
  • the venous assembly 100' is then preferably connected to the venous blood line of an extracorporeal treatment device, such as a hemodialysis machine (not shown).
  • blood is withdrawn from the arterial lumen 200 and treated blood is returned to the vessel 18 via the venous lumen 200'.
  • the respective valves 150 are adapted to facilitate the direction of blood flow preferred for each lumen 200, 200'.
  • each respective valve 150 is adapted to facilitate flow therethrough even if the assemblies 100, 100' are not connected to the proper extracorporeal bloodlines. In a situation involving improper connections, it is preferable that each respective valve 150 would allow flow at decreased levels, and that in a case of disconnection, each respective valve 150 would restrict the flow of blood, air or contaminants therethrough.

Abstract

La présente invention concerne un ensemble cathéter port (100) comprenant un corps (101) doté d'une extrémité distale (110), d'une extrémité proximale (120) et d'un canal longitudinal (102) entre ces deux extrémités. L'ensemble cathéter port comprend en outre une valve (150) disposée le long du canal longitudinal. La valve est conçue pour restreindre le flux dans au moins une direction et l'extrémité distale est adaptée pour être connectée à un cathéter. L'extrémité distale peut être insérée au moins partiellement sous la peau du patient après connexion à un cathéter, tandis que l'extrémité proximale peut être reliée à un dispositif extracorporel. La présente invention porte également sur un procédé d'insertion d'un ensemble cathéter comprenant l'ensemble cathéter port.
