Benefits of technology

[0012]According to an aspect of some embodiments of the invention, a method for dilating a urethra is provided according to which a dilation device is implanted around the outside of a urethra in an area affected by an enlarged prostate with at least part of the dilation device embedded in a surrounding enlarged prostate, thereby preventing clinically significant compression of the urethra.

Problems solved by technology

BPH can make it difficult to the bladder to completely empty, and is associated with other urinary system problems well known in the medical field.
Drug treatment may only be partially effective in some cases.

Embodiment Construction

[0063]The present invention, in some embodiments thereof, relates to methods and / or devices for treatment of intrabody lumens, and, more particularly, but not exclusively, to methods and devices for dilating and / or assisting in dilation and / or maintaining dilation of the urethra to relieve obstruction resulting, for example, from benign prostatic hyperplasia (BPH).

[0064]An aspect of some embodiments of the invention relates to treatment of an obstructed urethra, by implanting one or more structural elements in a prostate gland, optionally near a wall of the urethra. Optionally, such structural elements prevent collapsing of the urethra by the pressure of the prostate. A potential benefit of such positioning of structural elements is that urine flow contacts only natural endothelial tissue, onto which it does not aggregate. A potential benefit of such positioning is that endothelial tissue damage is reduced (e.g., to a small number of puncture points), potentially reducing complicati...

Abstract

A dilation device for an intrabody lumen, for example, a urethra partially occluded by an enlarged prostate in the form of a curved element configured to be implanted around the lumen and add resilience to the lumen, and a method for dilating such a lumen by implanting a dilation device around the outside of the lumen with at least part of the dilation device embedded in surrounding, thereby preventing clinically significant compression of the lumen. Also, an implantation device for such a dilation device in the form of a mounting device configured to carry the dilation device; and a releasably attached movable holder, with the mounting device and holder configured to deliver the dilation device though a working channel to a desired position in a lumen, and to implant the dilation device through a wall of the lumen to a position surrounding the lumen.

Description

RELATED APPLICATION / S[0001]This application claims priority to U.S. Provisional Application 61 / 202,634, filed 20 Mar. 2009, the contents of which is incorporated by reference herein as if fully set forth.FIELD OF THE INVENTION[0002]The present invention, in some embodiments thereof, relates to methods and devices for treatment of intrabody lumens, and, more particularly, but not exclusively, to methods and devices for dilating and / or assisting in dilation and / or maintaining dilation of the urethra to relieve obstruction resulting, for example from benign prostatic hyperplasia (BPH).BACKGROUND OF THE INVENTION[0003]It is common for the prostate gland to become enlarged as a man ages. As a male matures, the prostate goes through two main periods of growth, first early in puberty, and then again at around age 25, when the growth begins, and continues on through life. One of the effects of this continued growth can be pressure on the urethra, the passage through which urine passes from ...
