Abstract
This disclosure contains methods, devices, and systems for object removal from a body, including removal of a stent from a body. Some methods of the present disclosure include inflating a balloon on a catheter, engaging a stent with a socket defined by a surface of the balloon, the surface inwardly sloped toward a lumen of the catheter, and retracting a portion of the stent through the socket and into the lumen. The present disclosure also includes methods for making a catheter, including forming a balloon, inverting a portion of the balloon, and attaching the balloon to a catheter such that a surface of the balloon defines a socket that is inwardly sloped toward a lumen of the catheter.

1-19. (canceled)
A device for removal of an object from within a body, comprising:
- an inwardly sloped receiving socket connected to a catheter shaft, the receiving socket comprising a plurality of arms, each arm having a proximal end and a distal end, the proximal end of each arm attached to the catheter, the distal end of each arm projects outward, each arm is moveable having a compressed position and an expanded position;
- a flexible polymer material connecting the plurality of arms, the catheter shaft having a distal end and a lumen with a distal end opening on the distal end of the catheter shaft, the lumen having an inner diameter profile at the distal end opening;
- and
- a suction force to move the object through the inwardly sloped receiving socket and into the lumen.
A system for removal of an object from within a body, comprising:
- an inwardly sloped receiving socket connected to a catheter shaft, the receiving socket comprising a plurality of arms, each arm having a proximal end and a distal end, the proximal end of each arm attached to the catheter, the distal end of each arm projects outward, each arm is moveable having a compressed position and an expanded position;
- a flexible polymer material connecting the plurality of arms, the catheter shaft having a distal end and a lumen with a distal end opening on the distal end of the catheter shaft, the lumen having an inner diameter profile at the distal end opening;
- a pump to create a suction force to move the object through the inwardly sloped receiving socket and into the lumen;
- and
- a tool coaxially moveable within the catheter lumen, the tool sized to extend distally beyond a distal most end of the receiving socket for a selected distance, the tool having expandable arms attached to the distal end thereof.
