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.

15. Apparatus for implanting a urethral dilation device comprising:
-
a mounting device configured to carry the dilation device; and a movable holder attached to the mounting device; an inflatable urethral expander disposed within the delivery device, wherein the mounting device and holder are configured to deliver the dilation device to a desired position in a urethra, and to implant the dilation device through a wall of the urethra into an enlarged portion of a prostate to at least partially surround the urethra, with at least part of the dilation device surrounding the urethral expander during implantation. - View Dependent Claims (16, 18, 20, 22, 23, 24, 31, 32, 33, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69)

41. An implantation system for dilating a urethra at least partially obstructed by an enlarged prostate comprising:
-
a dilation device configured to be at least partially embedded in an enlarged portion of the prostate; and a delivery device for the dilation device including; a mounting device to which the dilation device is removably attached; a holder for the dilation device that is attached to the mounting device, wherein the mounting device and the holder are operable to deliver the dilation device to a desired position in a urethra, and to implant the dilation device through a wall of the prostate to circumferentially surround at least part of the urethra; and an inflatable urethral expander disposed within the delivery device during delivery to the implantation site, wherein the dilation device at least partially surrounds the urethral expander during implantation. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58)
