Patent number: 9168188Abstract: Apparatus and methods for cutting a material, especially with low material speed and high cutting torque. In some embodiments, the apparatus is a hand-held device for quietly cutting through an orthopedic cast with little or no generation of debris. In yet other embodiments, there is a method for automatically advancing material past a shearing surface, such that the shearing action occurs at about the same velocity as the advancement. In yet other embodiments, there is a device for cutting material between a foot and a sharp edge, with the bottom of the foot being under the sharp edge to protect the skin of the patient.Type: GrantFiled: November 13, 2008Date of Patent: October 27, 2015Assignee: OrthoPediatrics CorporationInventors: Paul A.

Publication number: 20120016481Abstract: Medical devices having one or more rotatable linkable components or segments, delivered in a first orientation relative to a component guide into a tissue cavity, such as the interbody vertebral space. After delivery, each segment may be rotated to a second, different orientation relative to the component guide, such as into a permanent vertical standing position. The segments achieve maximum distraction of the cavity space such as adjacent vertebra end plates, while using a minimal invasive surgical (MIS) approach. When the segments are tightened in place, the device provides long-term stability. The device can be used as a distraction instrument and/or permanent implant that can be used for interbody fusion, nuclear replacement, or anywhere in the body where a stable distraction of tissue and/or the implantation of material such as a device with an MIS approach is desired.Type: ApplicationFiled: September 23, 2011Publication date: January 19, 2012Applicant: MORPHOGENY, LLCInventor: Paul Zwirkoski

Patent number: 7833275Abstract: A method and apparatus for performing a minimally invasive total hip arthroplasty. An approximately 3.75-5 centimeter (1.5-2 inch) anterior incision is made in line with the femoral neck. The femoral neck is severed from the femoral shaft and removed through the anterior incision. The acetabulum is prepared for receiving an acetabular cup through the anterior incision, and the acetabular cup is placed into the acetabulum through the anterior incision. A posterior incision of approximately 2-3 centimeters (0.8-1.2 inches) is generally aligned with the axis of the femoral shaft and provides access to the femoral shaft. Preparation of the femoral shaft including the reaming and rasping thereof is performed through the posterior incision, and the femoral stem is inserted through the posterior incision for implantation in the femur.Type: GrantFiled: September 26, 2005Date of Patent: November 16, 2010Assignee: Zimmer Technology, Inc.Inventors: Dana Mears, Kevin Greig, Paul A Zwirkoski
