1. An anastomosis device comprising:
- an elongate body comprising an open drainage lumen extending through at least a portion of a length of the elongate body, a drainage aperture at a distal end of the elongate body for communication with a proximal end of the elongate body through the drainage lumen, a balloon spaced from the drainage aperture along the length of the elongate body, and tissue approximating structure extendable from the elongate body and spaced proximally from the balloon along the length of the elongate body.

Abstract
Described are methods and devices relating to anastomosis procedures, including those that reconnect the urethra and bladder after a radical prostatectomy, wherein the devices incorporate tissue approximating structure to maintain contact between tissues for healing the tissues together.

13. An anastomosis device comprising
an elongate body having a body wall, a proximal end, and a distal end, a drainage aperture at the distal end, a drainage lumen extending along at least a portion of a length of the elongate body and connecting the drainage aperture to the proximal end, an inflatable balloon spaced proximally from the drainage aperture along the length of the elongate body, an inflation lumen extending within a length of the body wall, connecting the balloon to the proximal end, distal tissue approximating structure comprising at least one distal tine connected to a distal frame, each distal tine extendably supported within an aperture of a distal tine deflector, a distal actuating mechanism operably connecting the distal frame to the proximal end of the device, through an actuating lumen extending along a length of the elongate body in the body wall, proximal tissue approximating structure comprising at least one proximal tine connected to a proximal frame, each proximal tine extendably supported within an aperture of a proximal tine deflector, a proximal actuating mechanism operably connecting the proximal frame to the proximal end of the device, through the actuating lumen.

14. A method of performing urethral anastomosis, the method comprising
inserting a portion of an anastomosis device into a urethra, the anastomosis device comprising: -
an elongate body comprising an open drainage lumen extending through at least a portion of a length of the elongate body, a drainage aperture at a distal end of the elongate body for communication with a proximal end of the elongate body through the open drainage lumen, a balloon spaced from the drainage aperture along the length of the elongate body, and tissue approximating structure extendable from the elongate body by use of an actuating mechanism, positioning the device so that the balloon is at least partially inserted into a bladder, inflating the balloon in the bladder, and extending the tissue approximating structure with the actuating mechanism to hold adjacent tissues together. - View Dependent Claims (15, 16, 17, 18)
