First Claim
Patent Images
1. A urethral implant for implantation into a urethral wall for treatment of incontinence, said urethral implant comprising:
- an elongated body formed of a resilient material, said body having a first position and a second position, said first position having a curved configuration, said second position being straighten from said first position such that said elongated body is implantable using an implant delivery device, wherein when said elongated body is placed within a urethral wall, said elongated body is capable of reshaping the urethral wall and thereby facilitating closure of the urethra.

Abstract
A rod-like or tube-like sphincteric closure device is micro-invasively implanted beneath the surface of the posterior mucosal wall to elevate the mucosa and close the lumen, by using a delivery device operated through the urethra. To initiate voiding, the muscle-rich anterior urethral wall contracts and widens the lumen beyond the closing or elevating range of the sphincteric closure device. For urethral obstruction, repelling magnets are micro-invasively implanted beneath the surface of mucosa with the delivery device through the urethra, to widen the lumen with magnetic force.

78. A method of micro-invasively treating a dysfunction of the urinary tract, the method comprising the steps of:
-
(a) inserting an implant delivery device into the urethra of a patient;
(b) orienting a recess of said implant delivery device adjacent to tissue at a first location;
(c) pressing said recess against the tissue, thereby causing a portion of the tissue to enter said recess;
(d) deploying a trocar into said recess;
(e) deploying an implant within a urethral wall located within said recess;
(f) retracting said trocar;
(g) and removing said implant delivery device, leaving said implant within the urethral wall. - View Dependent Claims (79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92)
