Fracture Fixation System and Method
First Claim
1. A system for stabilizing a bone fracture, comprising:
- a first anchorable member and a second anchorable member, each member having a central passageway, each member having a constrained non-anchoring configuration and a released anchoring configuration; and
a connector having a central passageway, the connector configured to attach to the proximal end of the first anchorable member and the distal end of the second anchorable member, such that the central passageways of the anchorable members and the connector form a continuous passageway.

Abstract
The invention relates to a system for stabilizing a bone fracture and methods for applying the system. The system includes a device with two anchorable members with an intervening connector and a passageway through the device. The anchorable members have a constrained non-anchoring configuration and a released anchoring configuration. The anchoring configuration includes a radially-expanded structure such as a plurality of struts. After implantation across a fracture site, the anchorable members are released from their linearly constrained configuration, and structural features radially self-expand, anchoring the device across the fracture. A flowable bone-filling material may be conveyed into the passageway of the device after implantation. The composition fills the space within the expanded structures of the anchorable members and flows into space surround the device, stabilizing it further in the implantation site.

22. A method for stabilizing a fractured bone, comprising:
-
forming a passage in the fractured bone through a proximal bone region, across the fracture, and into a distal bone region; positioning a bone fracture-stabilizing system in the passage, the system including; a first anchorable member and a second anchorable member, each member having a central passageway, each member having a constrained non-anchoring configuration and a released anchoring configuration; and a connector having a central passageway, the connector configured to attach to the proximal end of the first anchorable member and the distal end of the second anchorable member, such that the central passageways of the anchorable members and the connector form a continuous passageway; and anchoring the first anchoring member within the distal bone region and the second anchoring member within the proximal bone region. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
