Prostatic stent and delivery system

摘要

A collapsible and expandable stent (10) includes a body segment (12), first and second terminal ends (20, 24) spaced apart from each other, a substantially smooth wall (14) and a lumen (28) extending between the first and second ends. The device can be used for maintaining the patency of the prostatic urethra in a male patient. The stent may be designed according to the individual needs of particular patients. A delivery system (80) for deploying the stent and other collapsible and expandable stents in the body of the patient comprises a retractable sheath (82), a shaft (84) and a locking element (86) to reversibly lock the sheath to the shaft.
