20090319038 | CONNECTION SYSTEMS FOR TWO PIECE PROSTHETIC HEART VALVE ASSEMBLIES AND METHODS FOR MAKING AND USING THEM - A heart valve assembly includes a prosthesis and a prosthetic valve to replace a preexisting natural or prosthetic heart valve within a biological annulus. The prosthesis includes an annular member, a flexible core at least partially defining a sewing cuff extending radially outwardly from the annular member, a rail ring disposed between the flexible core and the annular member, and a plurality of guide rails extending from the rail ring through respective openings in the flexible core. A fabric covering covers the prosthesis, and the guide rails extend through respective openings in the fabric covering. The prosthetic valve includes a frame including receptacles for receiving respective guide rails. After implanting the prosthesis within a biological annulus, the prosthetic valve is advanced along the guide rails until retention elements on the guide rails engage the receptacles to secure the prosthetic valve relative to the prosthesis. | 12-24-2009 |
20100010616 | ATTACHMENT DEVICE AND METHODS OF USING THE SAME - Devices for attaching a first mass and a second mass and methods of making and using the same are disclosed. The devices can be made from an resilient, elastic or deformable materials. The devices can be used to attach a heart valve ring to a biological annulus. The devices can also be used for wound closure or a variety of other procedures such as anchoring a prosthesis to surrounding tissue or another prosthesis, tissue repair, such as in the closure of congenital defects such as septal heart defects, tissue or vessel anastomosis, fixation of tissue with or without a reinforcing mesh for hernia repair, orthopedic anchoring such as in bone fusing or tendon or muscle repair, ophthalmic indications, laparoscopic or endoscopic tissue repair or placement of prostheses, or use by robotic devices for procedures such as those above performed remotely. | 01-14-2010 |
20100070029 | HEART VALVE ASSEMBLIES AND METHODS FOR USING THEM - A heart valve assembly includes a base including a multi-lobular annular shape within a plane, a valve member or other annular body including a multi-lobular shape complementary to the shape of the base, and cooperating connectors on the base and the annular body for connecting the annular body to the base. The base includes an anchoring ring, and a flexible cuff for attaching the base to a biological annulus. The base and the annular body include guides for aligning their multi-lobular shapes, e.g., visual, tactile, or other markers, or tethers that extend from the base that are slidable through the annular body. During use, the base is attached to a biological annulus, the annular body is directed adjacent the annulus, oriented such that the multi-lobular shape of the annular body valve member is aligned with the base, and the annular body is attached to the base. | 03-18-2010 |
20120180799 | APPARATUS AND METHODS FOR TREATING SLEEP APNEA - Apparatus and methods are provided for treating sleep apnea, snoring, and the like using an implant within an oropharyngeal region adjacent an anterior longitudinal ligament. The implant may include a relatively narrow central region between first and second relatively wide outer regions. In one embodiment, one of the outer regions is compressible to allow the outer region to be directed through or behind the ligament such that the central region is disposed within or behind the ligament, the outer region being resiliently expandable after passing through or behind the ligament. In another embodiment, the implant may include one or more tines or other features that may be directed into adjacent tissue to secure the implant within the oropharyngeal region. | 07-19-2012 |
