Abstract
Abstract The present invention is directed toward a method and apparatus for performing an internal fixation of fractures of tubular bones using a balloon catheter fixation device (10) which is guided and transported through the medullary canal (42) and fracture site (41) of the bone by one or more guide wires (13,15) mounted in said balloon catheter fixation device (10). A bone cement is preferably applied to the fracture site (41) and the balloon catheter (16) is inflated inside the bone and tightened by applying pressure on the catheter (14) outside of the bone by tightening the catheter tube (14) and holding the same in plane in an inflated condition to apply a compression force across the fracture site (41) enhancing the stability of the fractured bone and promoting osseous healing.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
120 words
An assembly for setting a fractured bone comprising a balloon catheter (10) with tubing (14), said balloon catheter defining an inflation section (16) which inflates when said balloon catheter (10) is pressurized and at least one throughgoing lumen (11), a guide wire (13,15) mounted in said lumen (11), said inflation section (16) being inflated in a first fractured bone portion (48) to fixedly engage said bone segment and anchor means (30) mounted in another fractured bone portion (46) distal from said first fractured bone portion (48), said anchor means (30) being secured to said catheter tubing (14) to hold said balloon catheter (10) in a tensioned condition which provides compression on the fracture site (41) of fractured bone portions (46,48).
Claim 2
Dependent Claim
128 words
An assembly for setting fractured bones comprising a balloon catheter (10) with a tubing (14) having an inner lumen and an inflatable balloon (16) with fluted sides secured to said tubing (14) at the distal end thereof, said balloon (16) with fluted sides being in fluid communication with the lumen of said tubing, a guide wire (13,15) mounted to said balloon (16) and means (30) separate from said balloon catheter (10) adapted to be mounted in a portion (46) of said fractured bone distal from said balloon with fluted sides (16) to receive said tubing (14) and hold said balloon catheter (10) when said balloon with fluted sides (16) is inflated in a fixed stressed condition to provide compression on the fracture site of fractured bone portions (46,48).
Claim 3
Dependent Claim
159 words
An assembly for setting fractured bones comprising a balloon catheter (10) with a tubing (14) having an inner lumen and an inflatable balloon (16) secured to said tubing (16) at the distal end thereof, said balloon (16) being in fluid communication with the lumen of said tubing (14), a guide wire (13,15) mounted to said balloon (16) and means (30) separate from said balloon catheter (10) adapted to be mounted in a portion (46) of said fractured bone distal from said balloon (16) to receive said tubing (14) and hold said balloon catheter (10) when said balloon (16) is inflated in a fixed stressed condition to provide compression on the fracture side of fractured bone portions (46,48) and a fluid discharge means (18) connected to said balloon catheter (10) and communicating with said tubing lumen to allow fluid discharge from said fluid discharge means (18) into said tubing lumen to inflate the balloon (16) of said balloon catheter (10).
Claim 4
Dependent Claim
42 words
An assembly as claimed in claim 3, wherein said means (30) adapted to be mounted in a portion of said fractured bone is a hollow post member (30) with external screw threads (34) and includes set screw means (35,36,37,38) moveably mounted therein.
Claim 5
Dependent Claim
70 words
An assembly as claimed in claim 4, wherein said set screw means (37) comprises a ball seat (36) defined by said hollow post (30), a throughgoing channel (35) formed in said hollow post member (30) leading into said ball seat (36), a ball (38) seated in said ball seat (36) and a set screw (37) moveably mounted in said throughgoing channel (35) adapted to engage and move said ball (38).
Claim 6
Dependent Claim
37 words
An assembly as claimed in any one of the preceding claims, including a pressure monitoring means (50) connected to said balloon catheter (10) to measure the pressure of the inflated balloon (16) of said balloon catheter (10).
Claim 7
Dependent Claim
20 words
An assembly as claimed in any one of the preceding claims, wherein said catheter tubing (14) is flexible and reinforced.
Claim 8
Dependent Claim
164 words
An assembly for setting a fractured bone by holding the fractured bone portions (46,48) together under a compression force across the fracture site (41) comprising a balloon catheter (10) with a tubing (14) having an inner lumen and an inflatable balloon (10) secured to said tubing (14) and being in fluid communication with the lumen of said tubing (14), said balloon catheter (10) being sized to move within the medullary cavity of the bone, a guide wire (13,15) mounted to said balloon (16) and mounting means (30) adapted to be mounted in a portion (46) of said fractured bone distal from said balloon (16), said mounting means (30) selectively engaging said tubing (14) and holding said tubing (14) in a fixed stressed condition to provide compression on the fracture site (41) of fractured bone portions (46,48) after said balloon (10) has been inflated inside one of said bone portions, and means (18) connected to said tubing allowing the inflation of said balloon with fluid.
Claim 9
Dependent Claim
39 words
An assembly as claimed in claim 8, wherein said mounting means comprises a post member (30) with a throughgoing lumen (31) and set screw means (35,36,37,38) threadably mounted to said post member (30) and extending into said lumen (31).

An assembly as claimed in claim 9, wherein said set screw means (35,36,37,38) comprises a ball seat (36) defined by said post member (30) communicating with said lumen (31), a throughgoing channel (35) cut in said post member (30) leading into said ball seat (36), a ball (38) seated in said ball seat (36) and extending into said lumen (31) and a set screw (37) moveably mounted in said throughgoing channel (35) adapted to engage and move said ball (38) into said lumen (31).
Claim 11
Independent Claim

A method of setting a fractured bone by compression comprising the steps of: a) cutting an aperture (44) into one portion (46) of the fractured bone away from the site of the fracture (41) allowing communication with the medullary canal (42) of the bone; b) inserting a balloon catheter device (10) through the aperture (44) cut in the bone into the medullar cavity (42) of the bone; c) guiding the balloon catheter device (10) Past the fracture site (41) into another portion (48) of the fractured bone; d) inflating the balloon (16) of the balloon catheter device (10) to its maximum diameter so that the balloon catheter device (10) is held securely in place by the positive pressure of the balloon (16) applied to the intramedullary walls of the bone; and e) tightening the attached catheter (14) with the fixed balloon (10) in place to align the fracture and compress the proximal and distal portions (46,48) of the fracture bone together.
