Appl. No.:

13/346623

Inventors:

John Keggi - Woodbury CT, US
Louis Keppler - Valley City OH, US
Timothy McTighe - Chagrin Falls OH, US
Declan Brazil - Chatswood, AU
Carl Knobloch - East Taunton MA, US

International Classification:

A61F 2/38

US Classification:

623 2021, 623 2034, 606 88

Abstract:

A tibial component for use in conjunction with a knee replacement surgery. An inferior surface of the tibial component may be concave to thereby improve bonding between the tibial component and a tibia. The tibial component may produce low stress in the cement mantle during in-vivo loading. A stem extending from the inferior surface of the tibial component may include an anterior curvature to facilitate the use of minimally evasive surgical techniques. The stem may further include medial-lateral wing portions with a posterior curvature to provide improved support.

International Classification:

A61B 17/00

US Classification:

606 1

Abstract:

The present invention relates to an adaptable therapeutic, diagnostic or surgical guide for an intra-operative adjustment of a guidance element to a pre-planned position. An advantage and innovation of the present invention is that it provides a template or guide that adapts in a controlled way to a changed intra-operative anatomical situation compared to the default planned situation. This adaption maybe purely positional but it may also include force feedback. Feedback, either visual feedback or force feedback that results in an adjustment of a guidance element is also an aspect of the present invention. For example, the feedback can contain information either about the fit of the guide or template onto a bone (in case the guide or template fits onto one bone) or about the relative position of two bones of bone fragments (e.g. ligament tension between the femur and tibia).

International Classification:

A61B 19/00

US Classification:

128845

Abstract:

The present invention relates to a therapeutic, diagnostic or surgical tool, e.g. surgical guide frame for medical treatments, comprising: —a rigid structure, and —at least one functional guidance element (), wherein the rigid structure comprises means for positioning and holding the rigid structure around a soft tissue area of a patient and includes means for compressing the soft tissue area surrounded by the positioning and holding means as well as to the use of such a therapeutic, diagnostic or surgical tool for medical treatments, especially in areas where the therapeutic, diagnostic or surgical tool, e.g. surgical guide is supported on soft tissue.

International Classification:

A61B 17/80
A61B 17/17

US Classification:

606280, 606 88

Abstract:

A surgical method for tibia osteotomy includes attaching a patient-specific alignment guide to a corresponding surface of a tibia of a patient for whom the alignment guide is customized during a pre-operative planning stage and making a partial bone cut in the tibia through a planar slot of the alignment guide. The planar slot is oriented at a patient-specific angle relative to an anatomic axis of the patient and the angle is customized during the pre-operative planning stage. The method includes opening the bone cut to form an opening wedge, and inserting a patient-specific implantable wedge into the opening wedge.

International Classification:

A61B 17/17

US Classification:

606 88

Abstract:

A surgical kit for unicompartmental knee arthroplasty includes a unitary patient-specific unicompartmental tibial guide and a tibial drill template and other instruments. The tibial guide has a patient-specific body with an inner surface preoperatively configured to nestingly conform and mate in only one position with an anterior portion and a proximal portion of one compartment of a tibial bone of a specific patient. The tibial guide includes a drill guide portion preoperatively configured for drilling first and second anterior holes into the tibial bone for guiding a horizontal tibial resection. The tibial guide includes a vertical resection guide portion preoperatively configured for guiding a vertical resection through the tibial bone before the horizontal resection.

Appl. No.:

7/659845

Inventors:

Louis Keppler - Strongsville OH

International Classification:

A63B 2304

US Classification:

482 51

Abstract:

An exercise apparatus for a skater or similar athlete includes a flexible sheet having a smooth glide surface along which the feet of the exerciser can slide. Bumper assemblies are releasably connected with opposite ends of the flexible sheet. The flexible sheet is releasably clamped between a rigid base plate and a main section of a bumper assembly. A ramp section is releasably connected with the main section of a bumper assembly. A resiliently compressible bumper strip is provided on an upwardly sloping side surface of the ramp section to engage the foot of the exerciser. To further absorb forces resulting from enagagement of an exerciser's foot against the ramp section, a pad is provided between the ramp section and the main section of a bumper assembly. A mat extends beneath the flexible sheet and ramp section of a bumper assembly to stabilize the bumper assembly.

International Classification:

A63B 2304

US Classification:

272 70

Abstract:

An exercising apparatus for a speed skater or similar athlete including a base having a plurality of board members arranged in side-by-side relationship. Hinges pivotally connect adjacent board members to each other. A flexible plastic sheet overlays the board members and has a smooth glide surface on which the skater can slide. Bumpers are located at opposite ends of the base. Clamps releasably interconnect the base, the sheet, and the bumpers.
