Hermetically sealed prosthetic component and method therefor
First Claim
1. A prosthetic component for measuring a parameter comprising:
- a first structure having at least one support surface;
a second structure configured to couple to bone where the first and second structures are coupled together having at least one cavity therein;
electronic circuitry in the cavity; and
at least one sensor configured to measure the parameter where the electronic circuitry is coupled to the electronic circuitry and where the at least one cavity is hermetically sealed from an external environment.

Abstract
A prosthetic component suitable for long-term implantation is provided. The prosthetic component measures a parameter of the muscular-skeletal system is disclosed. The prosthetic component comprises a first structure having at least one support surface, a second structure having at least one feature configured to couple to bone, and at least one sensor. The electronic circuitry and sensors are hermetically sealed within the prosthetic component. The sensor couples to the support surface of the first structure. The first and second structure are coupled together housing the at least one sensor. In one embodiment, the first and second structure are welded together forming the hermetic seal that isolates the at least one sensor from an external environment. The at least one sensor can be a pressure sensor for measuring load and position of load.
