US Patent:

6972040, Dec 6, 2005

Filed:

Nov 19, 2002

Appl. No.:

10/299927

Inventors:

Robert F. Rioux - Ashland MA, US
Christopher R. O'Keefe - Holliston MA, US

Assignee:

Boston Scientific SciMed, Inc. - Maple Grove MN

International Classification:

A61F002/04

US Classification:

623 2366, 623 2365, 604 8

Abstract:

A urethral prosthesis with prostatic and bulbar segments connected by two types of ties allows the prosthesis to assume at least two configurations different with inter-segmental distances adapted to situations where the patient either has or does not have normal control of the external sphincter. This is particularly useful for a patient undergoing an anesthetic procedure that affects the external sphincter muscles. When the muscles are anesthetized, the prosthesis may provide constant urine voiding, and when the anesthetic effects wear off, the prosthesis may assume a different configuration to allow the sphincter to reassert control over urinary voiding.

International Classification:

A61M 29/00

US Classification:

604107, 604104

Abstract:

A stent for assisting urinary release in a male patient includes a first segment, a second segment, and a connecting member disposed between the first and second segments. The first segment includes a multi-winged malecot. When the stent is properly positioned within the patient's urinary system, the first segment is located on one side of the external sphincter with the multi-winged malecot located within the bladder to inhibit migration of the stent, and the second segment is located on the other side of the external sphincter and also tends to inhibit migration of the stent. The connecting segment is sized to extend through the external sphincter to couple the first and second segments together while not interfering with the normal operation of the external sphincter.

Abstract:

An anti-reflux drainage device includes an elongated member defining a lumen, and a valve disposed along the elongated member. The valve can include one or more lumens in fluid connection with the lumen of the elongated member, a socket, a shaft disposed in the socket, and a stopper connected to the shaft that occludes the second lumen when exposed to retrograde pressure. Another such device includes an elongated member and a ball valve. The ball valve can include a seat and a shoulder defined by the elongated member, and a ball disposed in the elongated member between the seat and shoulder that occludes lumen when exposed to retrograde pressure.
