Abstract
Abstract The present invention is directed toward a method for performing an internal fixation of fractures of tubular bones using a balloon catheter fixation device which is guided and transported through the medullary canal and fracture site of the bone by a plurality of guide wires mounted in said balloon catheter fixation device and once placed in position in the bone inflated inside the bone and tightened by applying pressure on the catheter outside of the bone to apply a compression force across the fracture site enhancing the stability of the fractured bone and promoting osseous healing.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
173 words
A method of setting a fractured bone by compression comprising the steps of: a) cutting an aperture into one portion of the fractured bone away from the site of the fracture allowing communication with the medullary canal of the bone; b) inserting a balloon catheter device and catheter guide wire means through the aperture cut in the bone into the medullar cavity of the bone; c) transporting the balloon catheter in the medullary canal of the bone past the fracture site by use of the catheter guide wire means to a point distal from the fractured site; d) inflating the balloon of the balloon catheter device to its maximum diameter so that the balloon catheter device is held securely in place by the positive pressure of the balloon applied to the intramedullary walls of the bone; and e) tensioning the attached catheter with the fixed balloon in place by securing the catheter under tension to holding means to align the fracture and compress the proximal and distal portions of the fractured bone together.
Claim 2
Independent Claim
173 words
A method of setting a fractured bone by compression comprising the steps of: a) cutting an aperture into one portion of the fractured bone away from the site of the fracture allowing communication with the medullary canal of the bone; b) inserting a balloon catheter device and catheter guide wire means through the aperture cut in the bone into the medullar cavity of the bone; c) transporting the balloon catheter in the medullary canal of the bone past the fracture site by use of the catheter guide wire means to a point distal from the fractured site; d) inflating the balloon of the balloon catheter device to its maximum diameter so that the balloon catheter device is held securely in place by the positive pressure of the balloon applied to the intramedullary walls of the bone; and e) tensioning the attached catheter with the fixed balloon in place by securing the catheter under tension to holding means to align the fracture and compress the proximal and distal portions of the fractured bone together.
Claim 3
Dependent Claim
25 words
The method of claim 1 including the step of; f) securing the catheter firmly to the bone at the insertion site with a fastener device.
Claim 4
Dependent Claim
16 words
The method of claim 2 wherein said securing step uses a screw as the securing device.
Claim 5
Dependent Claim
16 words
The method of claim 2 wherein said securing step uses a bolt as the securing device.
Claim 6
Dependent Claim
16 words
The method of claim 2 wherein said securing step uses a post as the securing device.
Claim 7
Dependent Claim
17 words
The method of claim 1 wherein said cutting step uses an bone awe to cut the aperture.
Claim 8
Dependent Claim
17 words
The method of claim 1 wherein said cutting step uses a bone drill to cut the aperture.
Claim 9
Dependent Claim
104 words
An assembly for setting a fractured bone comprising a balloon catheter with tubing, said balloon catheter defining an inflation section which inflates when said balloon catheter is pressurized and a plurality of throughgoing lumens, a guide wire mounted in each of said lumens, said inflation section being inflated in a fractured bone portion to fixedly engage said bone segment and anchor means adapted mounted in another fractured bone portion distal from said fractured bone portion, said anchor means being secured to said catheter tubing to hold said balloon catheter in a tensioned condition which provides compression on the fracture site of fractured bone portions.
Claim 10
Dependent Claim
104 words
An assembly for setting a fractured bone comprising a balloon catheter with tubing, said balloon catheter defining an inflation section which inflates when said balloon catheter is pressurized and a plurality of throughgoing lumens, a guide wire mounted in each of said lumens, said inflation section being inflated in a fractured bone portion to fixedly engage said bone segment and anchor means adapted mounted in another fractured bone portion distal from said fractured bone portion, said anchor means being secured to said catheter tubing to hold said balloon catheter in a tensioned condition which provides compression on the fracture site of fractured bone portions.
Claim 11
Dependent Claim
24 words
The assembly of claim 8 including a calibrated force measuring device secured to said tubing to measure the compression force on said balloon catheter.
Claim 12
Dependent Claim
27 words
The assembly of claim 8 including a pressure monitoring means connected to said balloon catheter to measure the pressure of the inflated balloon of said balloon catheter.
Claim 13
Dependent Claim
14 words
The assembly of claim 8 wherein said balloon catheter is a plastic extruded material.
Claim 14
Dependent Claim
15 words
The assembly of claim 11 wherein said catheter tubing is elastic and constructed of plastic.
Claim 15
Dependent Claim
16 words
The assembly of claim 8 wherein said holding means is a hollow post with holding means.
Claim 16
Dependent Claim
20 words
The assembly of claim 8 wherein said balloon portion of said balloon catheter has an outer wall which is ridged.
Claim 17
Dependent Claim
20 words
The assembly of claim 8 wherein said balloon portion of said balloon catheter has an outer wall which is smooth.
Claim 18
Dependent Claim
20 words
The assembly of claim 8 wherein said balloon portion of said balloon catheter has an outer wall which is fluted.
Claim 19
Dependent Claim
12 words
The assembly of claim 8 wherein said balloon catheter defines two lumens.
Claim 20
Dependent Claim
15 words
The assembly of claim 8 wherein said balloon catheter defines at a least three lumens.
Claim 21
Dependent Claim
15 words
The assembly of claim 8 wherein said guide wires are removably mounted in said lumens.
Claim 22
Dependent Claim
14 words
The assembly of claim 8 wherein said guide wires are secured in said lumens.
