  • FIG. 4J is a top view of a handle of a delivery system, according to an embodiment.
  • a distal facing design (wide part of cone facing the outlet) the implantable medical device 100 when implanted in the gallbladder of the subject is advantageous over a proximal facing design in order to minimize the surface area of the implantable medical device 100 in contact with the gallbladder wall.
  • each leg 130 may include a radiopaque marker positioned on the leg 130 between the leg end 212 and the anchor end 216.
  • the radiopaque marker includes a radiopaque band 222 coupled (wrapped or crimped) to the leg 130 between the leg end 212 and the anchor end 216.
  • the radiopaque marker includes a radiopaque coiled wire 224 wrapped around the leg 130 between the leg end 212 and the anchor end 216.
  • the radiopaque marker may be coupled to a waist region 228 of the leg 130. The waste region 228 is narrower in width than the leg end 212.
  • the outer release shaft 422 is retracted to expose the coupling element 426 of the inner control shaft 424, and the one or more biased paddles 428 bias outward from the coupling element 426 and disengage from the at least one side slot on the side of the collar 110 to release the implantable medical device 100 from the delivery system 400.
  • the catheter delivery system 400 may utilize a traditional guidewire access, and that guidewire access should not be allowed to interfere with the deployment of the implantable medical device 100. Additionally, it is advantageous to minimize the diameter of the catheter 420 as much as possible. Therefore, a guidewire insertion aid is described herein.
  • a removable thin-walled, peel-away tube 430 may be used. The peel-away tube 430 is inserted through the distal end of the constrained implantable medical device 100 before the implantable medical device 100 is packaged in order to: a) protect the lumen of the implantable medical device 100 and b) provide a smooth conduit for a guidewire 445 to be inserted past the implantable medical device 100 during the delivery procedure.
  • the stiff tip 442 of the guidewire 445 is inserted into the distal opening of the loading guide 432 and advanced into the delivery catheter. Once the tip 442 of the guidewire 445 is past the implantable medical device 100 and is sufficiently inside of the catheter 420, the loading guide 432 is removed by pulling it out of the catheter 420. A longitudinal slit is incorporated along the length of the loading guide 432 and the peel-away tube 430 so the loading guide 432 and the peel-away tube 430 can be peeled away from the guidewire 445.
  • inserting the portion of the outer release shaft of the hollow catheter of the delivery system at least partially into the organ of the subject includes using a bend of about 1 degree to about 45 degrees in the hollow catheter to the portion of the outer release shaft of the delivery system at a neck of the organ while utilizing a straight transhepatic path from skin of the subject to the organ.

Abstract

Des modes de réalisation de la présente invention concernent des systèmes de dispositifs médicaux implantables et des méthodes d'utilisation. Dans un mode de réalisation, un système de dispositif médical implantable comprend un dispositif médical implantable. Le dispositif médical implantable comprend un collier, un corps expansible et une pluralité de pieds. Le collier est configuré pour s'accoupler de manière amovible à au moins l'un d'un instrument de récupération ou d'un système de pose. Le corps expansible s'étend à partir du collier et comporte une ou plusieurs ouvertures lorsque le corps expansible est dans une configuration déployée. Le corps expansible comprend un matériau super-élastique et est configuré pour s'étendre à partir d'une configuration repliée pour une insertion dans un sujet à une forme sensiblement conique de la configuration déployée pour un ancrage à l'intérieur du sujet. La pluralité de pieds s'étendent à partir du corps expansible distal par rapport au collier.
