Patent Application Titled "Method and Apparatus for Implanting a Prosthesis" Published Online

May 12, 2014



By a News Reporter-Staff News Editor at Biotech Business Week -- According to news reporting originating from Washington, D.C., by NewsRx journalists, a patent application by the inventors DAVENPORT, Austen (Columbia City, IN); WITT, Tyler D. (Warsaw, IN), filed on October 23, 2012, was made available online on May 1, 2014 (see also Biotechnology Companies).

The assignee for this patent application is Biomet Manufacturing Corporation.

Reporters obtained the following quote from the background information supplied by the inventors: "This section provides background information related to the present disclosure which is not necessarily prior art. In performing a procedure on a patient, a prosthesis can be used to replace or augment a natural anatomical feature. For example, due to age, injury, disease, or other causes, a portion of the anatomy may need to be replaced or resurfaced. Examples include replacing an acetabulum on a patient either in conjunction with or separate from replacing or resurfacing a femoral head. An acetabular prosthesis is generally positioned within a prepared acetabulum.

"Positioning an acetabular prosthesis within a prepared acetabulum can include various dexterous movements. The acetabular prosthesis is generally positioned within the acetabulum in a selected alignment and position. The alignment of the acetabular prosthesis is generally selected to be relative to the natural anatomy. The prosthesis includes a central axis that is generally aligned and positioned or is selected to be aligned and positioned with a portion of the natural anatomy. In positioning the acetabular prosthesis in the selected position, both position and axial alignment can be selected.

"When positioning the acetabular prosthesis, it also needs to be engaged into the acetabulum with a selected force to ensure proper seating and positioning of the acetabular prosthesis. Accordingly, positioning the acetabular prosthesis generally requires dexterity on the part of the user, such as a surgeon, to position the acetabular prosthesis appropriately in a patient's anatomy. Then a force is applied to assist in fixing the prosthesis in the pelvis."

In addition to obtaining background information on this patent application, NewsRx editors also obtained the inventors' summary information for this patent application: "This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.

"An instrument to position an acetabular prosthesis in a prepared acetabulum is disclosed. The instrument can engage the acetabular prosthesis to establish both position and rotation control of the acetabular prosthesis. The acetabular engagement instrument can include at least a first portion to thread into an acetabular prosthesis and a second portion to engage a rotational control or holding portion of the acetabular prosthesis. Generally, the threaded portion can be positioned within an exterior member that can engage the acetabular prosthesis to fix rotation of the acetabular prosthesis relative to both of the threaded member and the exterior member.

"A process of positioning an acetabular prosthesis in a prepared acetabulum can include engaging the acetabular prosthesis for positioning relative to the prepared acetabulum. Engaging the acetabular prosthesis with an insertion instrument to fix it in both a position and rotation relative to the instrument can assist in positioning the acetabular prosthesis in the anatomy in a selected position and orientation. The acetabular prosthesis can be positioned in the prepared acetabulum both at a selected position and in a selected orientation between a central axis of the acetabular prosthesis and the anatomy.

"Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.

DRAWINGS

"The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.

"FIG. 1 is an exploded view of an acetabular inserter assembly;

"FIG. 2 is a detailed cross-sectional view of the acetabular inserter of FIG. 1 connected to an acetabular prosthesis with a portion of the inserter assembly in a first configuration;

"FIG. 3 is a detailed cross-sectional view of the inserter of FIG. 1 with a portion thereof in a second configuration;

"FIG. 4 is a perspective environmental view of the inserter positioning an acetabular prosthesis;

"FIG. 5 is a perspective view of a threaded rod portion of the inserter connected to an acetabular prosthesis;

"FIG. 6 is a detailed exploded view of a portion of the acetabular inserter interconnected with an acetabular prosthesis;

"FIG. 7 is an environmental view of an acetabular prosthesis inserter being removed from a portion of the inserter assembly after positioning the acetabular prosthesis; and

"FIG. 8 is a perspective environmental view of removing a portion of the acetabular prosthesis inserter assembly after removing a first portion of the inserter assembly.

"Corresponding reference numerals indicate corresponding parts throughout the several views of the drawings."
