An intraocular drainage device may include a monolithic silicone body having a flap, a rigid bottom plate having a portion configured to contact a corresponding portion of the flap, and a tube having a proximal end disposed between the flap and the rigid bottom plate. The corresponding portion of the flap may be configured to separate from the portion of the rigid bottom plate responsive to a fluid pressure in aqueous humor received from the tube. A plurality of parallel microgrooves may be formed on one or more portions of one or more outer surfaces of the intraocular drainage device.

A mitral repair annuloplasty ring that will accommodate implantation of a transcatheter valve therein for a valve-in-ring reoperation. The ring has a semi-rigid core with features that allow the ring to better conform to the cylindrical geometry of a transcatheter valve when implanted. The inner core defines a continuous peripheral D-shape with a substantially straight anterior side diametrically across from a more rounded posterior side with arcuate lateral sides therebetween. Segments of the ring core are subject to differing rates of bending due to variable radial thicknesses or radial slits opening to both inner and outer edges around the core periphery. One or more expansion joints may also be used to create the more circular final expanded shape. A plastically expandable sealing sleeve may surround the transcatheter valve for sealing gaps between the valve and annuloplasty ring.

A stent 10 includes corrugated pattern bodies 11 and connection elements 12. A corrugated pattern is formed of corrugated units 14, corrugated unit 14 including a first stem 15, a second stem 16, a third stem 17, a first top portion 18 coupling a first end portion 15a of the first stem 15 and a first end portion 16a of the second stem 16, and a second top portion 19 coupling a second end portion 16b of the second stem 16 and a first end portion 17a of the third stem 17. A second end portion 17b of the third stem 17 is connected to a second end portion 15b of the first stem 15 in another corrugated unit adjacent to corrugated unit. A first end portion 12a of connection element 12 is connected to the first top portion 18 of one of adjacent ones of the corrugated units 14, and a second end portion 12b of connection element 12 is connected to the second end portion 15b of the other one of the adjacent ones of the corrugated units 14.

A prosthesis that when implanted in the gastrointestinal tract does not impede the normal function of the pyloric sphincter. In some instances, the prosthesis is implanted as part of, or after, a sleeve gastrectomy procedure. The prosthesis includes a stent with an outer surface and a polymeric cover fully covering the outer surface of the stent. The stent includes a proximal stent flange; a proximal stent segment extending distally from the proximal stent flange; and an enlarged stent segment extending distally from the proximal stent segment.

A braided support structure that folds upon release from a delivery device wherein said fold is at least partially effected by varying the pic angle of the braids at locations where the folding is desired.

A medical device including an elongate member having a distal end portion, a proximal end portion, and a medial portion disposed between the distal end portion an the proximal end portion. The proximal end portion is configured to be disposed within a bladder of a patient. A portion of the proximal end portion is configured to contact an inner wall of the bladder to help retain the bladder in an expanded configuration.

A stent includes a strut formed into a cylindrical shape and extending in an axial direction. The strut includes outer peripheral portions extending around the axial and circumferential directions of the cylindrical shape. The outer peripheral portions are spaced apart from one another with gaps formed between adjacent outer peripheral portions. The strut includes a connection portion connecting the outer peripheral portions to each other in one of the gaps formed by the adjacent outer peripheral portions. The outer peripheral portions and the connection portion of the strut are integrally formed of a biodegradable polymer A portion of the strut includes a fragile portion which is snore fragile than other portions of the strut.

A radially expandable, tubular stent, includes a first section having a first crush resistance force and a second section have a second crush resistance force, wherein the first crush resistance force is less than the second crush resistance force. The first section is connected to the second section to form a tube, connection of the first and second sections extending in an axial direction of the tube.

An annuloplasty implant comprising an inner core of a shape memory material, an outer covering arranged radially outside said inner core material to cover at least part of said inner core, wherein said outer covering is resilient to conform to said inner core during movement of said shape memory material, wherein said outer covering comprises a material having surface properties to promote endothelialization. Two portions of the implant may be joined by a recess to be flexible with respect to each other by a bending motion at the recess. The two portions may also have a predefined breaking point at the recess.

An endoluminal prosthesis system for a branched body lumen comprises a branch vessel prosthesis. The branch vessel prosthesis is deployable within a branch vessel body lumen and comprises a stent having a generally tubular body portion, a flareable proximal end portion, and a coupling portion disposed intermediate the body portion and the flareable portion. The coupling portion is more crush-resistant than the body portion. The flareable proximal end may be disposed within a fenestrated stent graft with coupling portion disposed in the fenestration of the fenestrated stent graft.
