Abstract
Systems, devices, and methods are provided for retrieval of an implant from the prostatic urethra. Embodiments of retrieval systems can include a device for insertion into the patient and a proximal control device for use in grasping a portion of the implant and withdrawing the implant into a lumen of the retrieval system.

1-15. (canceled)
A system for retrieving an implant, the system comprising a retrieval device comprising:
- an outer tubular member having a distal end and a lumen;
- an inner elongate tubular member within the lumen of the outer tubular member;
- an elongate actuating member within a lumen of the inner elongate tubular member, the elongate actuating member having a proximal end coupled to a handle and a distal end comprising a hook;
- and
- a proximal control device coupled with the inner tubular member and releasably coupled with the outer tubular member through a coupling mechanism,
- wherein the proximal control device is configured to longitudinally move the inner elongate tubular member, the outer tubular member, and the elongate actuating member, and also configured to move the elongate actuating member within the lumen of the inner elongate tubular member.
27-35. (canceled)
A system for retrieving an implant, the system comprising a retrieval device comprising:
- an outer tubular member having a distal end and a lumen;
- an inner elongate tubular member within the lumen of the outer tubular member;
- an elongate actuating member within a lumen of the inner elongate tubular member, the elongate actuating member comprising a proximal end and a distal end, wherein the distal end comprises first and second jaws configured to open and close;
- and
- a proximal control device coupled with the elongate actuating member and the inner elongate tubular member, and releasably coupled with the outer tubular member through a coupling mechanism,
- wherein the proximal control device is configured to longitudinally move the elongate actuating member, inner elongate tubular member, and the outer tubular member, and also configured to move the elongate actuating member longitudinally within the lumen of the inner tubular member.
44-64. (canceled)
A system for retrieving an implant, the system comprising a retrieval device comprising:
- an outer tubular member having a distal end and a lumen;
- an inner elongate tubular member within the lumen of the outer tubular member;
- an elongate actuating member within a lumen of the inner elongate tubular member, the elongate actuating member comprising a proximal end and a distal end, wherein the distal end comprises a grasper;
- and
- a proximal control device coupled with the elongate actuating member and the inner elongate actuating member, and releasably coupled with the outer tubular member through a coupling mechanism,
- wherein the proximal control device is configured to longitudinally move the elongate actuating member, inner elongate tubular member, and the outer tubular member, and also configured to move the elongate actuating member longitudinally within the lumen of the inner tubular member.
