Abstract
Methods for removing a biomaterial implant and reversing occlusive effects of the biomaterial implant are described. In particular, methods for performing removal of biomaterial implants without damage to a body lumen where the biomaterial was previously implanted are presented. More specifically, methods of reversing an implant within a vas deferens using an ablation device are described.
Claims24
(canceled)
The method of claim 7, wherein the advancing of the distal tip includes moving the distal tip through an entire length of the implant.
3-4. (canceled)
The method of claim 7, further comprising:
- directing the flush solution to advance the ablated implant in an upstream to downstream direction relative to a direction of flow within the body lumen.
A method, comprising:
- inserting a delivery member into a body lumen;
- conveying, via the delivery member, a distal tip of an ablation device into the body lumen;
- actuating the ablation device to rotate the distal tip within the body lumen;
- advancing the distal tip, while the distal tip is rotating, within the body lumen to contact the implant thereby ablating the implant;
- conveying a flush solution into the body lumen;
- withdrawing, via the delivery member, the distal tip from the body lumen;
- inserting, via the delivery member, a supply tube into the body lumen;
- and
- conveying, via the supply tube, the flush solution into the body lumen.

13-20. (canceled)
A method, comprising:
- inserting a delivery member into a vas deferens, an implant being disposed within the vas deferens at an implant location to occlude a flow of sperm through the vas deferens;
- conveying, via the delivery member, a distal tip of an ablation device into the vas deferens;
- actuating the ablation device to cause disruption of the implant from within the vas deferens;
- and
- wherein disruption of the implant by the ablation device results in a total sperm motility of sperm passing through the vas deferens at the implant location after the disruption of the implant being at least about 25 micrometers per second.
28-29. (canceled)
A method, comprising:
- inserting a delivery member into a vas deferens, an implant being disposed within the vas deferens at an implant location to occlude a flow of sperm through the vas deferens;
- conveying, via the delivery member, a distal tip of an ablation device into the vas deferens;
- actuating the ablation device to cause disruption of the implant from within the vas deferens;
- advancing the distal tip through at least a central portion of the implant;
- and
- displacing the central portion of the implant to cause at least a portion of an outer perimeter of the implant to contract and collapse towards a center of the vas deferens.
