Drainage catheter
First Claim
1. A drainage catheter for suprapubic drainage of a patient'"'"'s bladder, said drainage catheter comprising:
- an elongated member having a drainage passage extending longitudinally therein, at least one drainage port providing external access for said drainage passage, and a distal portion positioned distal of said at least one drainage port;
a first retention member connected with said elongated member and positioned distal of said least one drainage port;
a second retention member connected with said elongated member and positioned proximal of said at least one drainage port;
the distal portion extending at least one centimeter distal of said first retention member and otherwise sized and configured for maintaining patency of a vessel in a vicinity of an anastomotic site; and
the distal portion being imperforate distal of said first retention member, thereby blocking external access of said drainage passage.

Abstract
A suprapubic drainage catheter (10) for draining the bladder and maintaining the patency of the urethra of a patient following a radical prostatectomy. The catheter includes an elongated member (11) having a drainage passage(12) extending longitudinally therein and a plurality of drainage ports (21) in a drainage portion (14) thereof for providing external access for the drainage passage in the bladder of the patient. First and second retention balloons (17, 18) are connected with the elongated member and positioned distally and proximally of the drainage ports, respectively. The elongated member also includes first and second inflation passages (26, 27) for individual and independent inflation and deflation of the retention balloons. One-way connector valves (32, 33) are positioned at the proximal end of the catheter for controlling inflation and deflation of the balloons via the inflation passages. The elongated member also includes a proximal portion (15) that extends through the percutaneous access site (30) for connection of a urine collection bag (not shown) to the drainage passage and further includes a distal portion (13) that extends from the bladder into the urethra through the anastomotic site (20) to maintain the patency of the urethra thereat.
