First Claim
Patent Images
1. An apparatus for positioning an implant relative to a fractured and main portion of a bone, the apparatus comprising:
- a handle;
a delivery member extending through the handle fixable in a discrete position with respect to the handle, the delivery member having a generally straight proximal portion and a curved member, the curved member including a distal end configured for engaging at least a portion of the fractured portion of the bone;
a guide channel extending through the handle, the guide channel including a longitudinal axis that is configured to substantially align with the distal end of the curved member, wherein the guide channel is configured to move with respect to the handle to position against the main portion of the bone to substantially approximate the fractured portion of the bone to the main portion of the bone, and wherein the guide channel is configured to receive at least a portion of a puncture member configured to move through at least one of the fractured portion and main portion of the bone; and
a locking mechanism coupled to the handle and configured to secure the delivery member with respect to the handle;
wherein the proximal portion of the delivery member and the guide channel are generally parallel, such that the delivery member and the guide channel can be passed through a single portal or incision.

8. An apparatus for positioning an implant relative to two portions of body tissue, the apparatus comprising:
-
a handle; a delivery member extending through the handle fixable in a discrete position with respect to the handle, the delivery member having a generally straight proximal portion and a curved member, the curved member including a distal end configured for engaging a portion of a first body tissue; a guide channel extending through the handle, the guide channel including a longitudinal axis that is configured to substantially align with the distal end of the curved member, wherein the guide channel is configured to move with respect to the handle to position against a portion of a second body tissue, wherein the delivery member and the guide channel are configured to compress the first body tissue and the second body tissue; and a locking mechanism coupled to the handle and configured to secure the delivery member with respect to the handle; wherein the proximal portion of the delivery member and the guide channel are generally parallel, such that the delivery member and the guide channel can be passed through a single portal or incision. - View Dependent Claims (9, 10, 11)
