Abstract:
The present invention relates generally to implants and tools for the fixation or fusion of joints or bone segments. These tools include tissue dilators and protectors. Other tools include broaches used to shape bores in bone. The tools can also include a system for removing an implant from bone. Implants can include assemblies of one or more implant structures that make possible the achievement of diverse interventions involving the fusion and/or stabilization of lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. Implants for fusing both sacroiliac joints of a patient include a long implant that extends across both sacroiliac joints.
Abstract:
The present disclosure is directed to a device for excising tissue including an outer hollow member having a lumen communicating with a distal opening. The device also includes an elongate member having a longitudinal axis and a distal end, the elongate member being longitudinally movable within the outer hollow member lumen such that the distal end of the elongate member can be moved from a first configuration distal to the outer hollow member distal opening and a second configuration more proximal to the outer hollow member distal opening. Further, the device includes at least one grasping member hingedly disposed about a distal portion of the elongate member along a generally longitudinal axis, wherein movement of the elongate member from the first configuration to the second configuration can cause displacement of the at least one grasping member about the generally longitudinal axis.
Abstract:
Systems and methods provide for the fixation of osteoporotic and non-osteoporotic long bones, especially Colles' fractures. A cannula having a circumferential opening is inserted into cancellous bone and directed such that the circumferential opening faces the fracture. The cannula is further adapted to receive an expandable structure, the expandable structure being inserted through the cannula until it is in registration with the circumferential opening. The expandable structure is expanded through the circumferential opening into cancellous bone and toward the fracture. The expansion of the expandable structure through the circumferential opening toward the fracture causes compression of cancellous bone and moves fractured cortical bone, thus creating a cavity proximal to the fracture. The cavity is then filled with a flowable bone filling material and the material allowed to harden.
