An antimicrobial containment cap is provided for use in a bone anchored prosthesis mounting system of the type having an externally protruding fixator pin carried by all implanted bone anchored mounting post, wherein the fixator pin accommodates removable attachment to an exoskeletal prosthesis such as a prosthetic limb or the like for an amputee. The containment cap, when mounted onto the fixator pin, is interposed between the prosthesis and soft tissue covering the end or stump of an amputated residual limb or the like. The containment cap carries and supports a selected antimicrobial or antibacterial agent in substantial contact with the soft stump tissue in a position closely overlying and substantially circumscribing the tissue interface with the externally protruding fixator pin to safeguard against infection. The containment cap is adapted for quick and easy periodic removal for cleaning and/or replenishment of the antimicrobial agent.

Antimicrobial containment cap for a bone anchored prosthesis mounting

A surgical method and implant for directing and securing a replacement ligament into the femur or tibia of the knee. A transverse tunnel may be formed in the femur approximately perpendicular to a femoral tunnel. A flexible strand passing through the transverse tunnel may be used to draw the replacement ligament into the femoral tunnel. The implant may then be placed into the transverse tunnel and through the replacement ligament to secure the replacement ligament in place. The implant may include an eyelet to receive the flexible strand and a tapered portion forming a shoulder to prevent the implant from being inserted too far into the transverse tunnel. The implant may also have a multi-angular configured portion to secure the implant within the transverse tunnel through an interference fit.

A catheter assembly for infusion or aspiration of an internal body site includes a catheter comprised of a tubular sidewall extending between a proximal end and an opposing distal end, the sidewall bounding a lumen. At least one port is formed on the catheter so as to communicate with the lumen. At least one filament extends outwardly from the first catheter. The filament is configured to form a fluid pathway within a body of a patient for fluid entering or exiting the at least one port of the catheter when the catheter is implanted within the body of the patient.

A pin ( ) is provided for securing a replacement ligament ( ) inside a tunnel ( ) of a receptor bone ( ). A threaded section ( ) of the pin ( ) engages and anchors the pin ( ) in the receptor bone ( ). A first taper ( ) opposite the threaded section ( ) is configured to enter a drilled hole ( ) which is transverse to the tunnel ( ), capture a looped replacement ligament ( ), and extend into the medial side ( ) of the receptor bone ( ). A second taper ( ) urges the replacement ligament ( ) against the wall ( ) of the tunnel ( ) and provides resistance when the second taper ( ) contacts the medial side ( ) of the bone ( ), thus signaling that the pin ( ) has been inserted to the proper depth. The body ( ) of the pin ( ) secures the looped replacement ligament ( ) in the tunnel ( ) and holds the replacement ligament ( ) in contact with the wall ( ) of the tunnel ( ) to insure ingrowth.

ACL fixation pin

A system for endosteal tibial ligament fixation with adjustable tensioning is disclosed. A grasping hook located on a shaft is used to draw a ligament graft into a contoured drill hole formed in a bone. A series of slanted ridges on the shaft can pass in only one direction through a securing push nut residing in the contoured drill hole, resulting in an interference fit that secures the attachment system, while allowing the tension of the ligament graft to be adjusted.

A pin (,) and method for use are provided for securing a replacement ligament (,) inside a tunnel (,) of a receptor bone (,). A threaded section (,) of the pin (,) engages and anchors the pin (,) in the receptor bone (,). A first taper (,) opposite the threaded section (,) is configured to enter a drilled hole (,) which is transverse to the tunnel (,), capture a looped replacement ligament (,), and extend into the medial side (,) of the receptor bone (,).

The body (,) of the pin (,) secures the looped replacement ligament (,) in the tunnel (,) and holds the replacement ligament (,) in contact with the wall (,) of the tunnel (,) to insure ingrowth.

ACL fixation pin and method

A process that utilizes a tendon threader for positioning and endosteally mounting a tendon within the endosteum of a closed tunnel end of a straight ligament tunnel that has been formed in a patient's knee in an arthroscopic surgical procedure for replacement of a cruciate ligament. The preferred tendon threader for use in a practice of the process includes a straight tubular body, with a handle arranged on one end, and the other tube end includes a pair of aligned wide longitudinal slots formed, with tube end remainder portions adjacent to which wide longitudinal slots each having a small longitudinal slot formed therein, the small slots for receiving a tendon, or a suture sewn onto the end of a tendon, fitted therein, forming a loop across the tube end. In a practice of the process the tendon threader is inserted into the straight ligament tunnel to where the tendon or suture loop is proximate to a ligament tunnel section end. Which procedure may be observed on a fluoroscopic monitor or utilizing an arthroscope fitted in the tendon threader tubular body. Whereat, a surgeon turns a pin into the side of the patient's knee, that travels through the ligament tunnel section and through the tendon or suture loop. The tendon threader is then removed leaving the tendon or suture folded over the pin, which tendon or suture end is then pulled over the pin to where the tendon ends are positioned over one another for mounting, under tension, as by stapling, onto the bone cortex surface adjacent to the straight ligament open tunnel end, completing the ligament mounting.
