Abstract
In some embodiments, a bone implant for percutaneous use is provided. The bone implant comprises a head, a body adjacent to the head and a tip opposite the head. At least the head, body or tip is configured to contact bone. An expandable member contacts at least one of the head, tip or body and is movable from an unexpanded configuration to an expanded configuration when deployed at a bone implant site. In some embodiments, a system for percutaneous bone harvesting is provided.
Claims8
A bone implant for percutaneous use, the bone implant comprising a head, a body adjacent to the head and a tip opposite the head, at least the head, body or tip configured to contact bone, and an expandable member adjacent to the tip, the expandable member movable from an unexpanded configuration to an expanded configuration when deployed at a bone implant site, wherein the expandable member comprises wings extended from the body toward the tip such that the wings and the tip join to form an acute angle at a juncture of the wings and the tip, wherein each of the wings comprises a proximal end adjacent to the body and a distal end away from the body, each of the wings comprising a circular opening disposed at the distal end of each of the wings and the tip also comprises a proximal end adjacent to the body and a distal end away from the body, the tip comprising a circular opening disposed at the distal end of the tip, the circular opening of each of the wings and the circular opening of the tip configured to collect bone from the bone implant site, and the bone implant site includes a bone harvesting site and the bone implant is configured to anchor at the bone harvesting site before, during or after bone is harvested such that the bone collected is removed from the bone harvesting site.
A bone implant for percutaneous use, the bone implant comprising a head, a body adjacent to the head and a tip opposite the head, at least the head, body or tip configured to contact bone, and an anchoring element adjacent to the tip configured to fix the bone implant to a bone implant site, wherein the anchoring element comprises wings extended from the body toward the tip such that the wings and the tip join to form an acute angle at a juncture of the wings and the tip, wherein each of the wings comprises a proximal end adjacent to the body and a distal end away from the body, each of the wings comprising a circular opening disposed at the distal end of each of the wings;
- and the tip also comprises a proximal end adjacent to the body and a distal end away from the body, the tip comprising a circular opening disposed at the distal end of the tip, the circular opening of each of the wings and the circular opening of the tip configured to collect bone from the bone implant site and the wings and the tip are configured to fix the bone implant to the bone implant site for collecting bone from the bone implant site, wherein the bone implant site includes a bone harvesting site and the bone implant is configured to anchor at the bone harvesting site before, during or after bone is harvested such that the bone collected is removed from the bone harvesting site.
A surgical system for percutaneous bone harvesting, the system comprising a bone implant comprising a head, a body adjacent to the head and a tip opposite the head, and an expandable member having an interior and an exterior, the exterior of the expandable member configured to contact bone at a bone implant site, wherein the exterior of the expandable member comprises wings extended from the body toward the tip such that the wings and the tip join to form an acute angle at a juncture of the wings and the tip, wherein each of the wings comprises a proximal end adjacent to the body and a distal end away from the body, each of the wings comprising a circular opening disposed at the distal end of each of the wings;
- and the tip also comprises a proximal end adjacent to the body and a distal end away from the body, the tip comprising a circular opening disposed at the distal end of the tip, the circular opening of each of the wings and the circular opening of the tip configured to collect bone from the bone implant site, and the bone implant site includes a bone harvesting site and the bone implant is configured to anchor at the bone harvesting site before, during or after bone is harvested such that the bone collected is removed from the bone harvesting site.
