ABSTRACT:
An anastomosis device providing increased functionality, reliability and safety through the use of designs addressing potential puncture of an inflation balloon being used to hold and approximate tissue. The anastomosis device can include bladder retention structures configured to engage and retain tissue without pointed or sharpened surfaces that can rupture the inflation balloon. The anastomosis device can include a reinforced or otherwise protected inflation balloon to resist puncturing by a bladder retention structure. The anastomosis device can include a catheter wall profile selected to physically prevent bladder retention structures from being forcibly bent back so as to avoid potential contact with and puncture of the inflation balloon. The anastomosis device can include a catheter funnel with an internal spring for preventing kinking of the catheter lumen while providing for flexibility and stretch of the funnel to absorb pulling or shock force which can rupture the inflation balloon.
