Patent number: 11246714Abstract: A surgical instrument for implanting a semi-rigid medical implant. The surgical instrument includes a shaft, an accessory shaft, an actuation mechanism and an implant engagement mechanism. The shaft has a channel formed therein. The shaft has a proximal end and a distal end. The accessory shaft is slidably mounted in the channel. The accessory shaft has a proximal end and a distal end. The actuation mechanism is mounted to the shaft proximate the proximal end thereof. The actuation mechanism is capable of causing the accessory shaft to slide with respect to the shaft. The implant engagement mechanism is attached to the distal end of the accessory shaft. The implant engagement mechanism is capable of engaging a semi-rigid surgical implant.Type: GrantFiled: March 27, 2019Date of Patent: February 15, 2022Assignee: SAG, LLCInventors: Matthew Kyle, Jeffrey C.

Publication number: 20170181866Abstract: A segmented disc nucleus replacement prosthesis and system for its implantation wherein the segments are made of a compliant, homogeneous material throughout. The prosthesis comprises a plurality of modular segments that mate together in a rail-and-slot arrangement. The rails and slots are configured to interlock and hold together under load despite being formed of compliant materials. In one embodiment, insertion tools and stabilizers are utilized for manipulation of the modular segments, the insertion tools and stabilizers being designed to accommodate for handling the compliant modular segments.Type: ApplicationFiled: November 29, 2016Publication date: June 29, 2017Inventors: Jeffrey C.

Publication number: 20100057144Abstract: A method and apparatus for repairing a damaged intervertebral disc nucleus in a minimally invasive manner utilizes a modular disc prosthesis preferably comprised of at least three modular segments and at least two rails that operably connect adjacent modular segments. In one embodiment, each modular segment includes a harder inner portion and a softer outer portion. Preferably, the rails operate to slidably connect and interlock adjacent modular segments. A stem portion of the rails that extends outside the periphery of the body of the prosthesis is removable after implantation such that the modular segments form an implanted unitary device that closely mimics the geometry of the disc nucleus cavity.Type: ApplicationFiled: August 26, 2009Publication date: March 4, 2010Inventors: Jeffrey C. Felt, Mark A. Rydell, Stephen H. Crosbie, John E. Sherman
