Abstract

A system and method for quantitatively assessing a press fit value (and provide a mechanism to evaluate optimal quantitative values) of any implant/bone interface regardless the variables involved including bone site preparation, material properties of bone and implant, implant geometry and coefficient of friction of the implant-bone interface without requiring a visual positional assessment of a depth of insertion. The following description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements.

First claim

What is claimed as new and desired to be protected by Letters Patent of the United States is:

1. An acetabular cup for a prepared cavity in a portion of bone, comprising:
an exterior shell portion defining a generally hemispherical interior cavity; and
said generally hemispherical exterior shell further includes a set of sensors; and
wherein each said sensor of said set of sensors each include a bioreceptor and a transducer communicated to said bioreceptor;
wherein each said bioreceptor is configured to produce a recognition event upon a recognition of a target analyte; and
wherein each said transducer is configured, responsive to said recognition event, to produce a recognition signal.

2. The acetabular cup of claim 1 wherein one or more of said sensors of said set of sensors are selected from the group consisting of a general sensor, a biologic sensor, a mechanical sensor, and combinations thereof.

3. The acetabular cup of claim 1 wherein said set of sensors include a set of bioreceptors immobilized on transducers configured to bio-recognize one or more of bacteria, white blood cells, and variety of a set of byproduct metabolites produced as a result of one or more of an infectious process, an accumulation of metal debris, an accumulation of implant debris, or an accumulation of polymer debris as analytes.

4. The acetabular cup of claim 3 wherein said biorecognition includes a biorecognition event and wherein said set of biorecptors transduce said biorecognition event into a signal configured for one or more of a measurement, quantification, and processing of diagnostic information.

5. The acetabular cup of claim 1 wherein said set of sensors include one or more wireless biological electronic sensors.

6. The acetabular cup of claim 1 wherein said set of sensors include one or more mechanical and biomechanical sensors as motion and linear displacement detectors.

7. The acetabular cup of claim 1 wherein said set of sensors include one or more force, load and displacement sensors directly at an implant/bone interface.

8. The acetabular cup of claim 1 wherein each said sensor of said set of sensors are configured for a continuous monitoring of said target analyte.

9. The acetabular cup of claim 1 wherein said target analyte includes a predetermined in situ substance producing said recognition event in said associated bioreceptor.

10. The acetabular cup of claim 9 wherein said recognition signal is produced, responsive to said recognition event, without receipt of a recognition signal.

11. An implant configured for an association with a portion of bone, comprising: a structure configured for an engagement with the portion of bone; and a set of sensors integrated with said structure; and wherein each said sensor of said set of sensors each include a bioreceptor and a transducer communicated to said bioreceptor; wherein each said bioreceptor is configured to produce a recognition event upon a recognition of a target analyte; and wherein each said transducer is configured, responsive to said recognition event, to produce a recognition signal, wherein the portion of bone includes a prepared cavity, wherein the association includes an installation into said prepared cavity, and wherein said structure includes an acetabular cup configured for said installation.

12. The acetabular cup of claim 11 wherein each said sensor of said set of sensors are configured for a continuous monitoring of said target analyte.

13. The implant of claim 11 wherein said target analyte includes a predetermined in situ substance producing said recognition event in said associated bioreceptor.

14. The implant of claim 13 wherein said recognition signal is produced, responsive to said recognition event, without receipt of a recognition signal.
