Patent number: 11439506Abstract: Prosthetic mitral valves described herein can be deployed using a transcatheter mitral valve delivery system and technique to interface and anchor in cooperation with the anatomical structures of a native mitral valve. This document describes prosthetic heart valve designs that interface with native mitral valve structures to create a fluid seal, thereby minimizing mitral regurgitation and paravalvular leaks. This document also describes prosthetic heart valve designs and techniques to manage blood flow through the left ventricular outflow tract. In addition, this document describes prosthetic heart valve designs and techniques that reduce the risk of interference between the prosthetic valves and chordae tendineae.Type: GrantFiled: February 25, 2020Date of Patent: September 13, 2022Assignee: Caisson Interventional LLCInventors: Kavitha Ganesan, Ramji Venkatasubramanian, Andrew T.

Patent number: 8092536Abstract: An assembly for the in situ formation of a prosthesis in an intervertebral disc space between adjacent vertebrae of a patient. At least one retention structure is located in the intervertebral disc space. A distal end of at least one lumen is located proximate the at least one retention structure. One or more in situ curable biomaterials are delivered to the intervertebral disc space through the first lumen and into engagement with the retention structure. The retention structure serves to retain at least a portion of the biomaterial in the intervertebral disc space by surface tension, adhesion, mechanical capture, friction, viscosity, and/or a variety of other mechanisms. The at least partially cured biomaterial and the at least one retention structure cooperate to comprise the prosthesis.Type: GrantFiled: September 3, 2008Date of Patent: January 10, 2012Assignee: Disc Dynamics, Inc.Inventors: Michael Ahrens, Erik O.

Patent number: 8012210Abstract: Intervertebral implant system for intervertebral implantation, are disclosed. An intervertebral implant system according to the present disclosure includes a frame having a peripheral wall defining a space therein, and a settable material introducible into the space of the frame. The settable material is a biocompatible load bearing material including and not limited to bone, composites, polymers of bone growth material, collagen, and insoluble collagen derivatives. The settable material is injectable into the space defined by the frame. The settable material may have an initial fluid condition wherein the fluid settable material cures to a hardened condition.Type: GrantFiled: January 11, 2005Date of Patent: September 6, 2011Assignee: Warsaw Orthopedic, Inc.Inventors: Jo-Wen Lin, Erik O. Martz, Joel F. Millets, Daniel Rosenthal, David Chow

Patent number: 7988699Abstract: A plurality of differently configured bone spinal implants for insertion in a spine have a cylindrical bore for receiving an insertion head stud. A plurality of instruments are disclosed each of which have a first connection element which is either a male or female member such as e.g., a ball and socket, a cylinder and socket and so on for forming either a stationary or articulating interchangeable joint for a plurality of disc processing heads or implant insertion heads. The plurality of disc space processing heads or implant insertion heads have a complementary second joint member for interchangeable attachment to the first connection element. The implant insertion heads or disc processing heads have different configurations for different shaped implants.Type: GrantFiled: October 19, 2005Date of Patent: August 2, 2011Assignee: Warsaw Orthopedic, Inc.Inventors: Erik O. Martz, Jo-Wen Lin, David Chow, Daniel Rosenthal

Patent number: 7988693Abstract: A chisel with U.V-shaped, saw tooth or other shaped opposing blades is used to form channels in adjacent vertebrae. The chisel has a projection extending from at least one of the top and bottom surfaces to limit depth of penetration into the vertebrae. A guide member may be attached to the forward tip of the chisel to guide the chisel into the disc space to uniformly chisel both adjacent vertebrae simultaneously to form a channel in the vertebrae. The so formed channels serve as sa guide for a second chisel having no guide member. The second chisel, which may be a box chisel, is used to complete the channels to the desired depth to receive an associated implant, typically of cortical bone. Other embodiments are disclosed in which a two step box chisel has a retractable guide member for initially guiding the chisel as it forms partial channels in the vertebrae disc space. The guide member is then retracted and the channels formed to the desired depth.Type: GrantFiled: July 11, 2003Date of Patent: August 2, 2011Assignee: Warsaw Orthopedic, Inc.Inventors: Erik O. Martz, David Chow
