Apparatus and methods for fracture repair
First Claim
1. An apparatus for treating a multi-segment fracture of a bone, the bone having an inner cavity, a first segment and a second segment, the apparatus comprising:
- a first anchoring substrate that extends longitudinally along a central axis of the apparatus and is configured to self-expand inside the inner cavity about the central axis, the first anchoring substrate comprising;
a first anchor receiving cavity that is configured to engage a first anchor that passes through a cortical bone of the first segment and penetrates the inner cavity; and
a second anchor receiving cavity that is configured to engage a second anchor that passes through a cortical bone of the second segment and penetrates the inner cavity; and
a second anchoring substrate that extends longitudinally along the central axis and is configured to self-expand inside the inner cavity about the central axis, the second anchoring substrate comprising;
a third anchor receiving cavity configured to engage the first anchor after the first anchor engages the first anchor receiving cavity and traverses a first space between the first anchor receiving cavity and the third anchor receiving cavity; and
a fourth anchor receiving cavity that is configured to engage the second anchor after the second anchor engages the second anchor receiving cavity and traverses a second space between the second anchor receiving cavity and the fourth anchor receiving cavity.

Abstract
Apparatus and methods for bone fracture repair. The apparatus may include a structural support for positioning a first bone segment relative to a second bone segment. The apparatus may include an anchoring substrate. The anchoring substrate may be configured to compress the first bone segment to the second bone segment. The anchoring substrate may transmit tension from a distal bone segment anchor in the first bone segment to a proximal bone segment anchor in the second bone segment. The apparatus may be configured to be deployed percutaneously in an inner cavity of a bone. The apparatus may be installed in an open fracture. The apparatus may be expanded, self-expanding or configured for mechanically actuation. Some embodiments of the apparatus may include a central axis member that may be used in conjunction with expansion of one or both of the structural support and the anchoring substrate to configure the apparatus.

20. An apparatus for treating a fracture of a bone, the bone having an inner cavity, the apparatus defining a central axis and comprising:
-
a first anchoring substrate; a first anchor engaging cell; and a second anchoring substrate;
wherein;the first anchoring substrate is configured to expand the first anchor engaging cell inside the inner cavity between the second anchoring substrate and cortical bone; the second anchoring substrate is configured to expand a second anchor engaging cell inside the inner cavity between the central axis and the first anchoring substrate; the first anchor engaging cell is configured to engage an anchor that penetrates the first anchoring substrate; the first anchor engaging cell is spaced apart from the second anchor engaging cell; and the second anchor engaging cell is configured to engage the anchor after the first anchor engaging cell engages the anchor. - View Dependent Claims (21, 22, 23, 24, 25)
