Anastomosis device and method
View Patent ↗An apparatus and method for using an anastomosis device to repair severed tissues resulting from a surgical medical procedure such as a radical prostatectomy, ilio-orthotopic neobladder construction, cystoprostatectomy, cystectomy, urethral anastomosis, or ureteral anastomosis.
1. A method for performing a ureter-to-ureter anastomosis procedure comprising:
providing an anastomosis device including a distalmost pair of tines and a medial inflation balloon, said distalmost pair of tines including a first tine set and a second tine set with each tine set being located between a distal end and the medial inflation balloon;
advancing the distal end of the anastomosis device such that the distal end leads the anastomosis device through a urinary tract and into a severed ureteral member such that the first tine set is positioned within a distal severed ureter portion and the second tine set is positioned within a proximal severed ureter portion, said proximal severed ureter portion being attached to a bladder;
extending the first tine set to grasp the distal severed ureter portion;
inflating the medial inflation balloon within the bladder such that the medial inflation balloon is proximate the proximal severed ureter portion;
pushing on the bladder with the medial inflation balloon to direct the proximal severed ureter portion into contact with the distal severed ureter portion; and
extending the second tine set to grasp the proximal severed ureter portion and retain the proximal severed ureter portion and the distal severed ureter portion in approximation.
2. The method of claim 1 , further comprising:
draining fluid in the distal severed ureter portion through a drainage aperture at the distal end of the anastomosis device.
3. The method of claim 1 , further comprising
maintaining approximation of the proximal severed ureter portion and the distal severed ureter portion throughout a healing period.
