Anastomosis device and related methods
First Claim
1. An anastomosis catheter device comprisinga flexible elongate body comprising a proximal end, a distal end, and a body wall extending along a length of the flexible elongate body,positionable tissue approximating structure that can be positioned length-wise along the elongate body and that can be extended and retracted from the body wall over a range of positions along the length of the elongate body to contact tissue for anastomosis,an inflatable balloon at the distal end and an inflation lumen extending from the proximal end to the balloon, anda drainage lumen extending from a drainage aperture at the distal end to the proximal end.

Abstract
Described are methods and devices relating to reconnecting the urethra and bladder after a radical prostatectomy, wherein the devices incorporate tissue approximating structure to maintain contact between a severed bladder neck tissue and a severed urethral stump tissue, preferably without the use of sutures.

9. An anastomosis device comprising
an elongate body comprising a body wall and a lumen, each extending along a length of the elongate body, the lumen comprising a hollow central channel, positionable tissue approximating structure that can be positioned length-wise along the elongate body and that can be extended and retracted from the body wall over a range of positions along the length of the elongate body to contact tissue for anastomosis, comprising a distal positionable tissue approximating structure within the hollow central channel of the elongate body, the distal positionable tissue approximating structure being capable of extending from the elongate body to contact tissue for anastomosis, and comprising a tine support and a tine assembly, and a proximal positionable tissue approximating structure within the hollow central channel of the elongate body, the proximal positionable tissue approximating structure being capable of extending from the elongate body on the proximal side of the distal positionable tissue approximating structure, and comprising a tine support and a tine assembly, and wherein the distal postionable tissue approximating structure and the proximal positionable tissue approximating structure can be positioned independently inside the elongate body and each tine assembly can be independently actuated to extend from the elongate body.

10. An anastomosis catheter comprising
an elongate body comprising a body wall and a lumen, each extending along a length of the elongate body, the lumen comprising a hollow central channel, positionable tissue approximating structure that can be positioned length-wise along the elongate body and that can be extended and retracted from the body wall over a range of positions along the length of the elongate body to contact tissue for anastomosis, comprising: -
a distal positionable tissue approximating structure within the hollow central channel of the elongate body, the distal positionable tissue approximating structure being capable of extending from the elongate body to contact tissue for anastomosis, a proximal positionable tissue approximating structure within the hollow central channel of the elongate body, the proximal positionable tissue approximating structure being capable of extending from the elongate body on the proximal side of the distal positionable tissue approximating structure, an inflatable balloon at a distal end of the device, an inflation lumen extending from the balloon to a proximal end of the device, and a drainage lumen extending from a drainage aperture at the distal end to a drainage port at the proximal end of the device.

11. A method of performing anastomosis, the method comprising
inserting a portion of an anastomosis device into a body lumen, the anastomosis device comprising an elongate body comprising a body wall and a lumen, each extending along a length of the elongate body, and positionable tissue approximating structure that can be positioned length-wise relative to the elongate body and that can be extended and retracted from the body wall over a range of positions along the length of the elongate body, moving the positionable tissue approximating structure along a length of the elongate body, extending the positionable tissue approximating structure from a location along the length of the device, and using the positionable tissue approximating structure to hold severed tissue during anastomosis.
