Abstract: Methods and devices for preparing an acetabulum for receiving an acetabular component in a hip replacement procedure. The methods may include aligning a first guide in an acetabular notch of the acetabulum and determining a reference point in the acetabulum. The first guide is removed from the acetabulum and then a second guide is positioned in the acetabulum and oriented with the reference point. While the second guide is positioned in the acetabulum, the acetabular margin is reamed with a reamer. During reaming, the reamer is contacted against a rim of the second guide which prevents additional reaming of the acetabular notch below the rim of the second guide.

Abstract: Devices and methods for use in a hip replacement surgical procedure. One aspect includes methods and devices for reaming selective regions of the femoral canal. This may include reaming distal and proximal sections of the femoral canal prior to reaming a middle region of the canal. Another aspect includes a dummy implant and methods of use. The dummy implant is inserted into the femoral canal and may be used for one or more of retraction of the femur, gauging a space with the acetabulum, and further revising the femoral cut. The aspects may be used together in a single surgical procedure or separately in different surgical procedures.

Abstract: Guides configured to guide one or more osteotomes to remove a femoral component that is implanted in a femur. When implanted, the femoral component includes a stem implanted within the femur, a proximal end that extends from the femur, and a receptacle in the proximal end. The guides are configured to attach to the femoral component and attach to the receptacle in the femoral component. The guides include one or more openings sized to guide the osteotomes along the stem of the femoral component. The guides may further include multiple different sections that can be attached together.

Abstract: A catheter that comprises a sheath that is connected at opposing ends to concentric tubes that move relative to each other in a manner that alternatively covers and exposes a medical device loaded onto the catheter. A portion of the sheath is arranged so as to invert upon itself so that axial movement of one tube relative to the other simultaneously moves the inversion point over or away from the device, alternatively covering or exposing the device.

Abstract: Methods for delivering a medical device loaded onto a catheter include positioning a first tube relative to a second concentric tube such that sheathing material having a first end affixed to the first tube and a second end affixed to the second tube forms an inner layer and an outer layer having at least one inversion point, such that no portion of the first tube is between any portion of the inner and outer layers of the sheathing material. Upon positioning the catheter at a desired target site the first tube can be moved relative to the second tube so that the inversion point moves to expose the medical device, thereby permitting expansion of the medical device at the target site.

Abstract: An acetabular component of a hip replacement implant that is configured to be attached to an acetabulum and to receive a femoral component of the hip replacement implant. The component includes a concave body with a closed end configured to seat against the acetabulum and an open end configured to receive the femoral component. At least one radiological marker is positioned on the body and is visibly distinct from the body on X-ray imaging. The radiological markers may include an elongated shape with a length measured between a first end and a second end. The radiological markers may be shorter than the body such that they do not extend completely around the body and the first and second ends are spaced apart from one another.

Abstract: The present invention is related to an article of footwear, namely an interactive activity integrated into the article of footwear. The interactive activity may be operated when the article of footwear is either in motion or stationary. The interactive activity instructs the user to respond. Upon a correct or incorrect response, the interactive activity will provide either further instruction or provide a signal that informs the user of the propriety of their response. The interactive activity may be a music tutorial, a game, or an educational tool.
