Systems and Methods for Bone Stabilization and Fixation
Systems for the minimally invasive repair, stabilization and/or fixation of a fractured bone, such as a rib, are disclosed. The systems include one or more rods/support members that are designed to extend along a dimension of a bone being repaired and secure the fractured bone. The support members can be photodynamic, and are formed using an expandable member that is filled with a light-sensitive liquid that is cured to form the rigid support member. Two or more clamps are used to secure the support member(s) to the rib or other bone. Minimally invasive surgical methods for securing the systems to a fractured bone are also disclosed.
Systems and Methods for Internal Bone Fixation
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.
Methods for creating, inserting, and removing an intramedullary sleeve system for bone treatment and stabilization
An orthopedic intramedullary sleeve apparatus for internal bone fixation for bone fracture treatment of a patient. The apparatus may comprise a multilayer sleeve component comprising one or more access valves disposed on a surface of the sleeve. Each access valve may comprise one or more resealable ports for injecting polymers or monomers or resins or any curable types of cement. The sleeve component may be positioned inside the intramedullary cavity in a minimally invasive way and removed from the intramedullary cavity.
Method of creating biocompatible polymeric resin systems for bone repair and management
A photocurable device injection system for creating in situ polymerization via light or free-radical to enable fractured bone fixation. The system comprises a photosensitive polymeric resin sensitive to light, temperature, oxygen, enzymes, or a combination thereof. The photosensitive polymeric resin may be configured to cure at room temperature or physiological temperature with a light source. The photosensitive polymeric resin may be configured to depolymerize with ultrasonication, sonication, or a combination thereof. The system further comprises an implantable 3-dimensional biocompatible pouch comprising an optical light guide. The system further comprises one or more micro-sized ultrasonication probes configured to contact a three-dimensional pouch by one or more openings. The one or more probes may be configured to enable polymer outflow.

METHODS FOR CREATING, INSERTING, AND REMOVING AN INTRAMEDULLARY SLEEVE SYSTEM FOR BONE TREATMENT AND STABILIZATION
An orthopedic intramedullary sleeve apparatus for internal bone fixation for bone fracture treatment of a patient. The apparatus may comprise a multilayer sleeve component comprising one or more access valves disposed on a surface of the sleeve. Each access valve may comprise one or more resealable ports for injecting polymers or monomers or resins or any curable types of cement. The sleeve component may be positioned inside the intramedullary cavity in a minimally invasive way and removed from the intramedullary cavity.
Systems and Methods for Anti-Microbial Effect for Bones
Systems and methods for restructure and stabilization of bones that provide an anti-microbial effect are disclosed herein. A device includes a delivery catheter having an inner void for passing at least one light sensitive liquid, and an inner lumen; an expandable member releasably engaging the distal end of the delivery catheter; at least one channel positioned in the expandable member; and a light conducting fiber sized to pass through the inner lumen of the delivery catheter and into the expandable member, wherein, when the light conducting fiber is in the at least one channel, the light conducting fiber is able to disperse light energy to provide an anti-microbial effect. When the light conducting fiber is in the expandable member, the light conducting fiber is able to disperse the light energy to initiate hardening of the light sensitive liquid within the expandable member to form a photodynamic implant.
Apparatus for delivery of reinforcing materials to bone
An apparatus and methods for delivery of reinforcing materials to a weakened or fractured bone is disclosed. An apparatus for delivering a reinforcing mixture to a bone including a tube having a proximal end, a distal end, and a longitudinal axis therebetween, wherein the tube has at least one inner lumen capable of allowing a bone reinforcing mixture to pass therethrough; a balloon engaging the tube wherein the balloon expands from a substantially deflated state to a substantially inflated state upon the bone reinforcing mixture entering the balloon; and at least one light guide extending through the tube into the balloon to guide a light into the balloon.
DEVICE AND METHOD FOR ESTABLISHING AN ANCHORAGE IN TISSUE
A perforated sheath is anchored in a tissue opening with the aid of a tool, wherein the anchorage is achieved with the aid of mechanical vibration and a material which is liquefiable by the vibration. The tool includes a vibrating element and a counter element. Distal portions of both elements are introduced into the sheath to be in contact with each other at an interface. The vibrating element is connected to a vibration source and the vibrating element and the counter element are held against each other for effecting liquefaction of the liquefiable material at the interface. Under the effect of the force applied to the vibrating and counter element for holding them against each other, the liquefied material flows from the interface through the sheath perforation and penetrates the tissue.
