METHODS AND DEVICES FOR URETHRAL TREATMENT
First Claim
1. A system for treatment of a urethra that is constricted due to BPH comprising:
- a positioning device including a positioning guide visible outside the urethra for determining the location of the area to be treatedan execution device for executing the treatment comprising;
a dilation unit including an expandable element positionable to enlarge the urethra in the area to be treated and a delivery shaft connected to the expandable element;
a cutter including a blade positionable to form a cut in the inner surface of the tissue surrounding the area to be treated as indicated by the positioning device; and
an implant carrier releasably connectable to an implant for delivery to the area to be treated including a shaft operable to release the implant into the cut;
wherein the dilation unit is operable before release of the implant.

Abstract
A system and method for treating a constricted bodily lumen, for example, a urethra constricted due to BPH. The method includes a planning stage, during which an area requiring treatment is visually identified, and an execution stage during which the lumen is expanded, a cut is formed in the inner surface of the tissue defining the lumen, and an implant is deployed in the cut. The implant can be an open C-shaped ring, and can be formed of a biodegradable material, or can be removed at a selected time after implantation. The system is formed of a planning device anchorable in the lumen and constructed to facilitate location of an area to be treated, and execution device constructed to deliver an implant, to expand the lumen, to form a cut in the inner surface of tissue defining the lumen, and to release the implant for deployment into the cut.

40. A method for treating a urethra that is constricted due to BPP comprising:
-
identifying a constricted area of the urethra requiring treatment; using a transurathrally inserted execution device, delivering a substantially C-shaped implant in a compressed condition for deployment at the treatment area; expanding the urethra in the treatment area; forming a cut in the inner surface of the prostate surrounding the constricted area; and inserting the implant into the cut after the urethra has been expanded with an open portion facing the rectum wall to maintain the expansion of then urethra. - View Dependent Claims (41, 43, 50, 51, 52, 53, 58, 59, 68, 69)

65. An execution device for a system for treatment of a constricted intrabody lumen comprising:
-
a dilation unit including an expandable element to enlarge the lumen in an area to be treated; an implant carrier to releasably deliver an implant to the area of the lumen to be treated as identified during a preliminary planning stage of the treatment; a cutter including a blade positionable to form a cut in the inner surface of the tissue surrounding the area to be treated to receive the implant by application of electrical or electromechanical energy to the tissue; and a release mechanism for separating the implant from the implant carrier.
