Bone Fixation Pin With Rotary Cutting Tip
US Patent:
6159210, Dec 12, 2000
Filed:
Jan 14, 1998
Appl. No.:
9/052790
Inventors:
Michael J. Voor - Louisville KY
Assignee:
Research Corporation Technologies, Inc. - Tucson AZ
International Classification:
A61B 1756
US Classification:
606 56
Abstract:
A fixation pin and methods for attaching an immobilizing device or frame to a bone or to the skull of a patient with a skeletal injury are provided. A preferred embodiment of the pin comprises an externally threaded cylindrical body having on its leading end a shoulder and a smaller diameter coaxial cylindrical post with a rotary cutting tip on its face. The post fits snugly into a hole drilled into the bone by the cutting tip without the need for a high axial force to insert and hold the post in place. Drilling the hole with a rotary cutting tip on the face of the post minimizes lateral damage to the bone. The minimal lateral bone damage and the low axial force provide for a low incidence of pin loosening and side effects such as infections secondary to loosening and headaches. The shoulder limits the depth of penetration of the cutting tip into the bone. A crescent shaped halo utilizing the fixation pin is also provided.
Mems Capacitive Bending And Axial Strain Sensor
US Patent:
7854174, Dec 21, 2010
Filed:
Feb 26, 2009
Appl. No.:

Assignee:
OrthoData Technologies LLC - Louisville KY
International Classification:
G01L 1/14
US Classification:
73780, 73775, 73777
Abstract:
A three-dimensional micro-electro-mechanical-systems (MEMS) capacitive bending and axial strain sensor capacitor is described. Two independent comb structures, incorporating suspended polysilicon interdigitated fingers, are fabricated simultaneously on a substrate that can displace independently of each other while attached to a substrate undergoing bending or axial deformation. A change in spacing between the interdigitated fingers will output a change in capacitance of the sensor and is the primary mode of operation of the device. On the bottom and to the end of each comb structure, a glass pad is attached to the comb structure to allow for ample surface area for affixing the sensor to a substrate. During fabrication, tethers are used to connect each comb structure to maintain equal spacing between the fingers before attachment to the substrate. After attachment, the tethers are broken to allow independent movement of each comb structure.

US Patent:
2012005, Mar 1, 2012
Filed:
Aug 26, 2011
Appl. No.:
13/219376
Inventors:
Michael J. Voor - Louisville KY, US
Assignee:
UNIVERSITY OF LOUISVILLE RESEARCH FOUNDATION, INC. - Louisville KY
International Classification:
A61F 2/28, A61J 1/00, A61P 19/08, A61K 35/32, A61K 9/14
US Classification:
623 1611, 424549, 424400, 206568
Abstract:
A bone graft composition includes a biologically-resorbable cement and a plurality of processed bone particles, where each of the bone particles have a shape configured to interconnect with adjacent bone particles. A method for treating a bone defect using the bone graft compositions includes providing the bone graft composition and administering an effective amount of the bone graft composition to a site of a bone defect in a subject. Kits including a biologically-resorbable cement powder and a plurality of processed bone particles are also provided.
Device And Method To Prevent Hip Fractures
US Patent:
2010002, Jan 28, 2010
Filed:
Jul 23, 2009
Appl. No.:
12/508350
Inventors:
Michael J. Voor - Louisville KY, US
Assignee:
UNIVERSITY OF LOUISVILLE RESEARCH FOUNDATION, INC. - Louisville KY
International Classification:
A61B 17/56
US Classification:
606 64, 606 63
Abstract:
A device for preventing a hip fracture includes: a shaft having a first end and a second end and an expanding means for engaging the femoral head at the first end. The shaft is positioned in a hole of a predetermined depth in a femur. The hole extends from the greater trochanter to the femoral head of the femur, such that the first end is positioned in the femoral head and the second end is positioned in the greater trochanter. The device is oriented substantially perpendicular to the long axis of the femoral shaft.
Rapidly Adjustable Threaded Pin Clamp
US Patent:
6942664, Sep 13, 2005
Filed:

Appl. No.:
10/446311
Inventors:
Michael J. Voor - Louisville KY, US

Seid W. Waddell - Lagrange KY, US
Assignee:
University of Louisville Research Foundation, Inc. - Louisville KY
International Classification:
A61B017/56
US Classification:
606 54
Abstract:
A clamp for the rapid and accurate positioning of a threaded fixation pin has a central body defining a channel therethrough for receiving a fixation pin. The clamp also includes a locking member with a lower surface adapted to engage and mate with the threads of the fixation pin. Thus, the fixation pin can be rapidly inserted into the desired bone structure by rotating the fixation pin, and as the fixation pin is rotated, it also advances forward due to the engagement of the threads of the fixation pin with the locking member of the clamp. If the forward advance caused by the engagement of the threads of the fixation pin with the locking member can not keep pace with the cutting action, the resultant resistance to insertion in the form of a rearward directed force will cause the locking member to rise up and disengage the threads of the fixation pin.
