Appl. No.:

13/088916

Inventors:

Robert A. Rabiner - Tiverton RI, US
Richard Scott Rader - Wayland MA, US

International Classification:

A61M 29/00
A61B 18/00

US Classification:

60410302, 606 15

Abstract:

Photodynamic bone stabilization and drug delivery systems are disclosed herein. In an embodiment, a photodynamic bone stabilization and drug delivery system of the present disclosure includes an insertion catheter having an inner void for passing at least one light-sensitive liquid, and an inner lumen; an expandable portion releasably engaging a distal end of the insertion catheter, wherein the expandable portion comprises an inner expandable portion in communication with the inner lumen of the insertion catheter and sufficiently designed to maintain a light-sensitive liquid therein; and an outer expandable portion, surrounding the inner expandable portion, sufficiently designed to house and release at least one additive from the outer expandable portion in an outward direction from the inner expandable portion; and a light-conducting fiber sized to pass through the inner lumen of the insertion catheter and into the inner expandable portion for delivering light energy to the light-sensitive liquid.

Abstract:

Combination photodynamic devices for repair and stabilization of a fractured or a weakened bone are disclosed herein. In an embodiment, a combination photodynamic device includes a load bearing member and one or more conformable members connected to the load bearing member, the conformable member expandable from a deflated state to an inflated state. The load bearing member is designed to reside inside a cavity of fractured or weakened bone and act as internal bone fixation and stabilization device. The conformable member is designed to anchor the load bearing member inside a bone cavity, transform the load bearing member from a flexible state to a rigid state, contribute to fixating and stabilizing a fractured or a weakened bone, and provide longitudinal and rotational stability to a fractured or a weakened bone during the healing process or combinations thereof.

Abstract:

Devices and methods for restructure and stabilization of a fractured or weakened head of a bone are disclosed herein. A device includes a delivery catheter having a proximal end and a distal end, 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; and a light conducting fiber sized to pass through the inner lumen of the delivery catheter and into the expandable member. The expandable member moves from a deflated state to an inflated state when the light sensitive liquid is passed to the expandable member. 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.

Abstract:

Photodynamic devices for replacement of an articular head of a bone are provided. In an embodiment, a photodynamic device includes a photodynamic support member and an articular member attachable, either fixedly or removably, to the photodynamic support member and having a bearing surface. In an embodiment, the articular member includes a recess designed to receive the photodynamic support member. In an embodiment, the photodynamic support member includes an opening into which a shaft of the articular member can be inserted to attach the articular member to the photodynamic support member.
