Devices and methods for separating a catheter from an internal bone fixation implant

A method comprising:

• providing a catheter cutter device comprising:
• a first tubular member having a proximal end, a distal end, and a lumen extending therethrough, wherein the proximal end of the first tubular member includes a threaded shank portion and a plain shank portion, and wherein the distal end of the first tubular member terminates in a cutting head comprising a cutting blade;
• and
• a second tubular member having a proximal end, a distal end, and a lumen extending therethrough, wherein the proximal end of the second tubular member includes a handle having internal threads, wherein the first tubular member is coaxially disposed within the lumen of the second tubular member so that the cutting head at the distal end of the first tubular member extends beyond the distal end of the second tubular member,
• wherein the threaded shank portion of the first tubular member mates with the internal threads of the handle of the second tubular member to form a secure mechanical connection;
• positioning the cutting head of the catheter cutter device at a junction between an introducer catheter and a hardened expandable balloon, wherein the introducer catheter is coaxially disposed within the lumen of the first tubular member of the catheter cutter device;
• connecting a drill to the plain shank portion of the first tubular member;
• powering on the drill causing the first tubular member to rotate and the second tubular member to move along the first tubular members axis in a linear direction while not rotating, the linear movement of the second tubular member pressing down on the cutting head of the first tubular member so the cutting blade punctures the introducer catheter as the cutting blade rotates around the introducer catheter;
• and
• separating the introducer catheter from the hardened expandable balloon.

A kit comprising:

• an expandable balloon catheter;
• a biocompatible light curable liquid monomer;
• and
• a catheter cutter device, the catheter cutter device comprising:
• a first tubular member having a proximal end, a distal end, and a lumen extending therethrough, wherein the proximal end of the first tubular member includes a threaded shank portion and a plain shank portion, wherein the plain shank portion of the first tubular member is configured to connect the first tubular member into a chuck of a drill, and wherein the distal end of the first tubular member terminates in a cutting head comprising a cutting blade;
• and
• a second tubular member having a proximal end, a distal end, and a lumen extending therethrough, wherein the proximal end of the second tubular member includes a handle having internal threads, and wherein the threaded shank portion of the first tubular member is configured to mate with the internal threads of the handle of the second tubular member to form a secure mechanical connection.
