PULMONARY STENT REMOVAL DEVICE
First Claim
1. An apparatus for removing a removeably implanted device positioned within a body lumen, the apparatus comprising:
- an elongate tube having a central passage;
an inner member slideably disposed within the passage of the elongate tube; and
a coupling member disposed near a distal end of the inner member, said coupling member adapted to releasably engage a support element and/or a membrane of the implanted device.

Abstract
A removal tool for an implanted device, including pulmonary stents, occlusive devices, valved devices, and flow-restrictive devices, is provided. The removal tool includes an elongate tube having a central passage, a slideable inner member within the passage, and a coupling member disposed on the distal end of the inner member. The coupling member of the removal tool includes a distal tip configured to pierce a membrane of the implanted device. The coupling member also includes a coil or a hook configured to engage a support element of the implanted device. A method of removing implanted devices is also provided. A removal tool is placed adjacent to the device, the distal end of the tool is moved to pierce its membrane, a portion of the tool engages the support member, and the distal end of the tool is retracted along with the implanted device.

21. A method for removing a removeably implanted device positioned within a body lumen, the implanted device comprising a frame at least partially covered by a membrane, the method comprising:
-
positioning a removal tool so that a distal end of the removal tool is adjacent to the implanted device; piercing the membrane of the implanted device with the distal end of the removal tool; capturing an element of the frame with the removal tool; and retracting the distal end of the removal tool along with the implanted device. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
