Embodiment Construction

[0019] Medical devices and methods for repairing weakened or fractured bones are disclosed herein. The devices disclosed herein are used as internal bone fixation devices and include a delivery catheter terminating in a removable comfortable member. During the repair of a fractured bone, the fitting member is placed in a contracted state within the cavity of the fractured bone. Once in the correct position, the comfort member expands from a contracted state to an expanded state by adding at least one reinforcing material. The at least one reinforcing material is then hardened within the fitting member using a light source. The hardened fitting member can then be removed from the delivery catheter and sealed to enclose the at least one reinforcing material within the fitting member. The hardened fit member remains within the cavity of the fractured bone and provides support and proper positioning to the fractured bone allowing repair, healing and strengthening of the fracture...

Abstract

Internal bone fixation devices and methods for using the devices for repairing a weakened or fractured bone are disclosed herein. A device for use in repairing a fractured bone includes a delivery catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, wherein the delivery catheter has an inner void for passage of at least one reinforcing material and an inner lumen for passage of a light source; a conformable member releasably engaging the distal end of the delivery catheter, wherein the conformable member moves from a deflated state to an inflated state when the at least one reinforcing material is delivered to the conformable member; and an adapter releasably engaging the proximal end of the delivery catheter for receiving the light source and the at least one reinforcing material.

Description

technical field [0001] Embodiments disclosed herein relate to medical devices for repairing weakened or fractured bones, and more particularly, to internal bone fixation devices and methods of using these devices to repair weakened or fractured bones. Background technique [0002] Fracture repair is the process of rejoining and realigning the ends of a broken bone. Fracture repair is required when it is necessary to restore the normal position and function of a broken bone. Throughout the healing phase of a fracture, the bone must be held firmly in place and supported until it is strong enough to bear weight. In the absence of proper repair of the fracture, misalignment of the bone may then occur, causing possible physical dysfunction of the bone or joints in that area of ​​the body. [0003] Until the last century, doctors relied on casts and splints to support the bone from outside the body (external fixation). However, the development of sterile surgery has reduced the...
