Abstract
A biocompatible medical device can be at least partially implantable into a living human or animal subject to provide active treatment of biofilm that can occur use within the subject. The medical device can include a catheter, including an interior conduit capable of permitting fluid flow. A heating device can be located on a portion of the catheter to be located within the subject, the heating device including at least a pair of electrodes having a variable spacing therebetween, the variable spacing specified to allow heat to be generated using a time-varying electromagnetic input signal providing a variable frequency to control a variable location along the electrodes at which heat is generated, such as can provide a virtual matrix of local heat sources.

(canceled)
A medical device that is at least partially insertable or implantable into a living human or animal subject, the medical device comprising:
- a body, sized and shaped to include a biocompatible portion that is configured to be insertable or implantable into the subject, the body including:
- an electrical conductor, connected or coupled to receive an AC electromagnetic input signal;
- and
- at least one of a semiconductor, a lossy dielectric, a thin-firm metal, or a crystalline substrate, arranged with respect to the electrical conductor to use the AC electromagnetic input signal varied to a specified frequency to select a sensor location in response thereto.
