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.
Claims16
A bone repair device comprising:
- a shaft formed from an expandable balloon formed from a conformable compliant material configured to have a changeable thickness to expand from an initial shape with a size and shape for implantation in a bone cavity to an expanded shape with a size and shape of the bone cavity into which it is implanted, wherein expanding the expandable balloon from the initial shape to the expanded shape shapes the expandable balloon to mirror the size and shape of the bone cavity to anchor the shaft inside the bone cavity, the shaft having a proximal end for inserting into the bone cavity and a distal end having a centrator;
- a light-curable material configured to be delivered to the expandable balloon and expand the expandable balloon from the initial shape to the expanded shape;
- and
- an articular member having an articular part, a bearing surface disposed on the articular part, and an attachment part in the shape of a recess configured to engage with the centrator of the shaft such that the articular member is secured to the distal end of the shaft,
- wherein the attachment part allows for adjustment of an angle of the articular member relative to a central axis of the shaft to position and anchor the articular member inside the bone cavity, and
- wherein the light-curable material is configured to be cured by light delivered by one or more light fibers to anchor the shaft inside the bone cavity.
A bone repair device comprising:
- a shaft formed from an expandable balloon formed from a conformable compliant material configured to have a changeable thickness to expand from an initial shape with a size and shape for implantation in a bone cavity to an expanded shape with a size and shape of the bone cavity into which it is implanted, wherein expanding the expandable balloon from the initial shape to the expanded shape shapes the expandable balloon to mirror the size and shape of the bone cavity to anchor the shaft inside the bone cavity, the shaft having a proximal end for inserting into the bone cavity and a distal end;
- a light-curable material configured to be delivered to the expandable balloon and expand the expandable balloon from the initial shape to the expanded shape;
- and
- an articular member having a pocket recess and a bearing surface, the pocket recess configured to complementarily engage the distal end of the shaft to position the distal end of the shaft within the pocket recess,
- wherein the light-curable material is configured to be cured by light delivered by one or more light fibers to anchor the shaft inside the bone cavity.
A bone repair device comprising:
- a shaft formed from an expandable balloon formed from a conformable compliant material configured to have a changeable thickness to expand from an initial shape with a size and shape for implantation in a bone cavity to an expanded shape with a size and shape of the bone cavity into which it is implanted, wherein expanding the expandable balloon from the initial shape to the expanded shape shapes the expandable balloon to mirror the size and shape of the bone cavity to anchor the shaft inside the bone cavity, the shaft having a proximal end for inserting into the bone cavity and a distal end having threads;
- a light-curable material configured to be delivered to the expandable balloon and expand the expandable balloon from the initial shape to the expanded shape;
- and
- an articular member having threads for complementary engaging the threads of the distal end of the shaft to couple the articular member with the shaft, and a bearing surface,
- wherein the light-curable material is configured to be cured by light delivered by one or more light fibers to anchor the shaft inside the bone cavity and form a rigid structure capable of providing longitudinal and rotational stability.
