Publication number: 20160317302Abstract: A device (100) for supporting a valve annulus is described that includes spaced apart support members (105) and a connecting member (110) extending between and connecting the support members. At least one adjustor (115) is also provided that is engaged with the connecting member and can be actuated to modify a length of the connecting member between two adjacent support members. In addition, each support member may include at least two channels extending through the support members at different heights with respect to an overall thickness of the respective support member. Each channel may receive a portion of the connecting member therethrough, and each support member may further include a passageway between the channels to allow selection of one of the channels. In this way, the device may be adjusted in at least two dimensions to support the valve leaflets and promote sufficient closure of the leaflets.Type: ApplicationFiled: December 16, 2014Publication date: November 3, 2016Inventors: Jeko Metodiev MADJAROV, Charles R.

Publication number: 20160317303Abstract: An annuloplasty repair segment for heart valve annulus repair. In one embodiment a multi-stranded cable replaces solid core wire for both the triscuspid and mitral valves. Cable allows for greater deployment flexibility for minimally-invasive surgical (MIS) implant, while still maintaining the required strength and similar tensile properties of solid-core wire. In addition, selective placement of point-welds or other such control points locally control other parameters such as the amount and direction of displacement as the ring undergoes external loading. Cable with well-placed control points result in a MIS annuloplasty ring with sufficient flexibility in the x-y plane to allow a surgeon to squeeze the ring into a small incision, such as for example 1 cm×1 cm, while maintaining structural rigidity under forces exerted on the implanted ring by the cardiac cycle and allowing for asymmetrical deflection to be designed into the product.Type: ApplicationFiled: April 29, 2016Publication date: November 3, 2016Inventors: John F. Migliazza, Bob Crockett, Tim Abram

Publication number: 20160317305Abstract: The present disclosure relates to laminated sealing members for prosthetic valves and methods of making the same. In a representative embodiment, an implantable prosthetic valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration comprises an annular frame having an inflow end and an outflow end, a leaflet structure positioned within the frame and secured thereto, and a laminate sealing member comprising an encapsulating material. The laminate sealing member has a main portion that encapsulates at least a portion of the frame and an end portion extending from the inflow end of the frame, and the end portion of the laminate sealing member is folded to form a cuff adjacent the inflow end of the frame and secured to the main portion of the laminate sealing member.Type: ApplicationFiled: April 27, 2016Publication date: November 3, 2016Inventors: Itai Pelled, Elena Sherman, Eran Goldberg, Kevin D. Rupp, Noam Nir

Publication number: 20160317306Abstract: One aspect provides advancing a distal end of a needle out of a bore of a tool, and capturing a suture in a slot formed through an exterior surface of the needle, with the suture engaged with a penile implant. The method includes retracting the distal end of the needle and a portion of the suture into the bore of the tool, and inserting a shaft of the tool into a corpora cavernosum of a penis and forcing the distal end of the needle and the portion of the suture out of the bore of the tool and through a glans of the penis. The method includes retracting the needle into the bore and retaining the portion of the suture exterior to the glans of the penis. Pulling on the suture pulls the penile implant into the corpora cavernosum of the penis.Type: ApplicationFiled: April 29, 2015Publication date: November 3, 2016Inventor: Jeffrey Brian Taylor

Publication number: 20160317307Abstract: An acetabular prosthesis is described that includes a shell having an outer surface and an inner surface, the outer surface defining an external shape. There is at least one through bore extending from the outer surface of the shell to the inner surface of the shell. At least one augment is configured to be positioned at least partially within the at least one through bore of the shell such that, in an assembled state, the shell and the at least one augment define a modified external shape.Type: ApplicationFiled: April 29, 2016Publication date: November 3, 2016Inventors: Kirk J. Bailey, Christopher Peters, Adolph V. Lombardi, Stephanie Klunk, Aaron P. Smith
