Systems and methods for internal bone fixation

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...

AI Technical Summary

Problems solved by technology

Traditional bone cement injection devices have difficulty adjusting or controlling bone cement injection volume or injection rate in real time in response to cancellous bone volume and density conditions encountered inside the fractured bone

Traditional bone cements can also cause complications, which include leakage of cement into the outer area of ​​the fractured bone site, which can lead to soft tissue damage as well as nerve root pain and shrinkage
