First Claim
Patent Images
1. A device for separating an internal bone fixation device from an introducer in a medullary space of a fractured bone, the device comprising:
- a functional portion having an outer shaft surrounding and controlling operation of a cutting mechanism,wherein the cutting mechanism has a contoured curved top surface for receiving the outer shaft and a contoured open bottom surface for positioning over the internal bone fixation device during a procedure for repairing a fractured bone,wherein the cutting mechanism includes a base section diverging into at least two arm sections, a distal end of the at least two arm sections having an inner radial surface composed of a semi-spherically shaped sharp cutting blade, andwherein the at least two arm sections surround a separation area of the introducer, the separation area located between a proximal end of the internal bone fixation device and a distal end of the introducer; and
a control portion having an actuating mechanism for initiating activation of the outer shaft.

6. A device for separating an internal bone fixation device from a delivery catheter in a medullary space of a fractured bone, the device comprising:
-
a functional portion having an outer shaft and a cutting mechanism at least partially surrounded by the outer shaft, wherein the cutting mechanism has a contoured curved top surface for receiving the outer shaft and a contoured open bottom surface for positioning over the internal bone fixation device during a procedure for repairing a fractured bone, and wherein the cutting mechanism comprises a base section diverging into at least two arm sections and includes a channel therein for receiving the delivery catheter such that the at least two arm sections surround the delivery catheter received in the cutting mechanism, and wherein a distal end of the at least two arm sections has an inner radial surface composed of a semi-spherically shaped sharp cutting blade which is compressible inward by a translation of the outer shaft in a distal direction along the cutting mechanism into the delivery catheter received within the cutting element; and an actuating mechanism for translating the outer shaft relative to the cutting mechanism. - View Dependent Claims (7, 8, 9)
