摘要:
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.
