Patent Images
1. An implantable pedometer for measuring use of a joint in a skeletal system, comprising:
- an elongated housing having an external surface, at least a portion of the external surface configured for bone engagement;
an acoustic sensor disposed within the housing, the sensor adapted for detecting a sound indicative of joint use;
a memory unit disposed within the cylindrical housing and in communication with the sensor, the memory unit adapted for storing a count data corresponding to the number of sounds indicative of joint use detected; and
a telemetry circuit configured for transmitting the count data outside of the skeletal system.

Abstract
An implantable pedometer for measuring the amount of joint use is disclosed. The implantable pedometer includes a sensor adapted for detecting indicators of joint usage. A counter is configured for storing count data corresponding to the number of indicators detected by the sensor and a telemetry circuit is configured for transmitting the count data outside of the body.
