Appl. No.:

13/395260

Inventors:

Ben Geebelen - Haasrode, BE
Roel Wirix-Speetjens - Maaseik, BE
Louis James Keppler - Strongsville OH, US
Wilfried Vancraen - Huldenberg, BE

Assignee:

Materialise N.V. - Leuven

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).

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.

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.

Inventors:

Louis Keppler - Strongsville OH

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.

Inventors:

- Leuven, BE
Louis KEPPLER - Valley City OH, US

International Classification:

A61B 17/17
A61B 17/56

Abstract:

Provided herein are patient-specific surgical guiding tools for positioning on a socket of a ball-and-socket joint, e.g., an acetabulum. The guiding tools comprise a central contact element fitting within the socket and one or more lateral contact elements fitting on the rim of the socket. The guiding tools allow accurate positioning of surgical tools such as alignment elements, according to a pre-operational planning. Methods for the manufacture and use of said guiding tools are also provided.
