Abstract
Provided herein are balloon delivery systems (BDSs) for deploying expandable implants at treatment locations within a subject. In particular provided herein are BDSs providing optimal deployment of bioresorbable vascular scaffolds (BVS). for example. within a coronary artery.
Claims28
A catheter system for placement of an implant within a subject, the system comprising:
- (a) a catheter comprising having distal and proximal ends;
- (b) an implant for insertion within a subject, wherein the implant comprises a lumen, wherein the catheter extends longitudinally through the lumen of the implant, and wherein the implant is capable of adopting a compacted conformation and an expanded conformation;
- (c) a stopper located at a position along the catheter that is proximal to the location of the implant on the catheter, wherein the stopper has a greater diameter than compacted conformation of the implant;
- and
- (d) a sheath that extends longitudinally around the catheter and envelops the implant;
- wherein the stopper prevents movement of the implant toward the proximal end of the catheter when the sheath is retracted toward the proximal end of the catheter.
3 more elements
A method of placing an implant within a treatment site in a subject, the method comprising:
- (a) inserting the system of one of claims 1-22 into a subject such that the implant is aligned with the treatment site;
- (b) retracting the sheath toward the proximal end of the catheter, thereby exposing the implant to the treatment site;
- and
- (c) allowing the implant to self-expand and/or applying mechanical outward force on the implant to place the implant into the expanded conformation within the treatment site.
