| 20130024003 | URETERAL STENT FOR IMPROVED PATIENT COMFORT - A ureteral stent for assisting the movement of urine along a patient's ureter and into the patient's bladder. The stent includes an elongated tubular segment extending toward the bladder from a kidney end region for placement in the renal cavity to a bladder end region. A central lumen connects at least one opening at the first end region to at least one opening in the bladder end region. Thin flexible tail(s) are attached to the bladder end region of the tubular segment at a point outside the bladder so as to receive urine from the opening in the bladder end region of the tubular segment and to transport urine from there across the ureter/bladder junction and into the bladder. The tails include an elongated external urine-transport surface sized and configured to transport urine along the ureter. The urine transporting surface(s) are sized and configured to extend along at least part of the ureter, across the ureter/bladder junction, and from there into the bladder. In some embodiments, the distal region includes a tubular body with a lumen in fluid communication with an interstitial area defined by one or more flexible filaments of the proximal region forming at least one loop. | 01-24-2013 |
| 20130131827 | METHODS AND MATERIALS FOR REPLACING A CIRCUMFERENTIAL SEGMENT OF AN ESOPHAGUS - This document provides methods and materials that can be used to replace a circumferential segment of an esophagus. For example, methods and materials that can be used to provide a tubular connection from one stump end of an esophagus to another stump end of the esophagus are provided. | 05-23-2013 |
| 20130173017 | UNIFORM EXPANDABLE AND COLLAPSIBLE STENT - A modified double helical and braided (platted) helical wire stent is described that provides for uniform collapsing and expansion of the stent body such that the stent collapses and expands in a uniform, predictable manner, reduces foreshortening, and is durable, stable, and reliable. | 07-04-2013 |
| 20140052272 | COMFORT STENTS - In one embodiment, a stent includes a retention portion and an elongate portion. The retention portion is configured to help retain the stent in place within a body of a patient. The elongate portion extends from the retention portion. The elongate portion has a sidewall defining a lumen and the outer surface of the sidewall includes a pattern. The sidewall has a first section and second section. The first section of the sidewall has a first thickness. The second section of the sidewall has a second thickens different than the first thickness. | 02-20-2014 |
| 20140114434 | MEDICAL DEVICE FOR IMPLANTATION INTO LUMINAL STRUCTURES - The present invention relates to expandable scaffolds such as stents. The vascular scaffolds may be formed from bioabsorbable polymers, metals or various combinations of metals and polymers. The stents of the present invention comprise a generally cylindrically shaped main body having a plurality of expandable first and second circumferential elements. The body of the vascular scaffold comprises a plurality of circumferential elements. At least two circumferential elements may be connected to form a pair of circumferential elements. There may be one or more connections between the circumferential elements forming the pair. Each pair of circumferential elements is connected to an adjacent pair of circumferential elements by at least one connection element. When expanded, at least a portion of the connection elements connecting the circumferential elements in the pairs and/or the connection elements connecting the circumferential elements in adjacent pairs form a contiguous spiral pattern which may form a helix(s). | 04-24-2014 |
| 20140163694 | PREFORM FOR AND AN ENDOLUMINAL PROSTHESIS - An endoluminal prosthesis may include a tubular graft extending in a longitudinal direction, where the graft has an inner surface forming a lumen extending a length of the graft. An elongate member may be attached to the graft in a circumferentially and longitudinally extending manner such that the elongate member forms a series of longitudinally spaced apart turns, each turn extending substantially around a circumference of the graft. The elongate member may torsion the graft in at least the circumferential direction and cause the graft to form circumferentially and longitudinally extending folds in the portions of the graft disposed between longitudinally adjacent turns of the elongate member. | 06-12-2014 |
| 20150142127 | URETERAL STENT FOR PLACEMENT IN A KIDNEY AND BLADDER - Provided is a ureteral stent (= | 05-21-2015 |
