Publication number: 20120046682Abstract: A surgical instrument system functional in multiple orthopedic applications, including but not limited to shoulder, knee, hip, wrist, ankle, spinal, or other joint procedures. The system comprises a cutting head which includes jaw members which may be urged between open and closed positions to providing a biting or chewing action for removal of targeted tissues. The instrument system is configured to be driven by an attached hub that translates a rotational movement into a reciprocating motion to open and close the jaw members. Suction for removal of bone fragments or other tissues is provided through a suction opening.Type: ApplicationFiled: September 13, 2011Publication date: February 23, 2012Applicants: MedicineLodge, Inc. dba IMDS Co-InnovationInventors: Keith J.

Publication number: 20120046747Abstract: A system and method for securing an ACL graftmay include a line routed through a plate. The plate may include an elongated body with a plurality of passageways, and a dogbone feature on at least one end of the body. The line may be routed to create at least one one-way slide so no knots are required. The line may form an adjustable loop that receives the graft. The adjustable loop is adjustable through the one-way slide feature. The plate may be configured to pass through a bone tunnel. The plate may be toggled after passage through the bone tunnel to prevent withdrawal back through the bone tunnel because the plate contact area is larger the bone tunnel area.Type: ApplicationFiled: August 26, 2011Publication date: February 23, 2012Applicant: MedicineLodge, Inc. dba IMDS Co-InnovationInventors: Daniel F.

Publication number: 20120010660Abstract: A modular implant for stabilizing the relative motion of spinal vertebrae comprises at least two pairs of plates which connect to two adjacent spinous processes, a spacer configured to be positioned between the spinous processes, and a fastener which pivotably connects to the plates and the spacer. The spacer is interchangeable and may comprise a variety of materials, each providing a different level of elasticity to the spinous processes. Relative motion between vertebrae can also be controlled by varying the surface configuration of the plates and by varying threading of the fastener. Several implants may be linked to provide stabilization across multiple vertebral levels, and the relative motion provided at each vertebral level may differ. A method for revising the implant is provided which comprises accessing the implant and replacing the spacer.Type: ApplicationFiled: September 19, 2011Publication date: January 12, 2012Applicant: MEDICINELODGE, INC.

Publication number: 20110313534Abstract: A knee prosthesis including femoral and tibial implants, a tibial insert and a cam post assembly. The femoral implant is secured to a femur and has a cam feature and condyles. The tibial implant is secured to a tibia. The tibial insert has articulating surfaces that match the contours of the condyles of the femoral implant, and may have a medial boss that aligns with the tibial implant to provide rotation about a medially displaced rotation axis. A cam post is secured to the tibial implant and passes through a channel of the tibial insert. A motion limiting structure provides limits to motion between the tibial insert and the tibial baseplate. The cam post assembly interacts with the femoral implant cam feature and allows more anatomically correct rollback and femoral external rotation during knee flexion, and varus/valgus support to the femur.Type: ApplicationFiled: July 22, 2011Publication date: December 22, 2011Applicants: MEDICINELODGE, INC.

Publication number: 20110208304Abstract: A method is provided for depositing a hard wear resistant surface onto a porous or non-porous base material of a medical implant. The wear resistant surface of the medical implant device may be formed by a Laser Based Metal Deposition (LBMD) method such as Laser Engineered Net Shaping (LENS). The wear resistant surface may include a blend of multiple different biocompatible materials. Further, functionally graded layers of biocompatible materials may be used to form the wear resistant surface. Usage of a porous material for the base may promote bone ingrowth to allow the implant to fuse strongly with the bone of a host patient. The hard wear resistant surface provides device longevity, particularly when applied to bearing surfaces such as artificial joint bearing surfaces or a dental implant bearing surfaces. An antimicrobial material such as silver may be deposited in combination with a metal to form an antimicrobial surface deposit.Type: ApplicationFiled: April 21, 2011Publication date: August 25, 2011Applicant: MEDICINELODGE, INC.
