Detecting improper energy transmission configuration in medical device system
A medical device system may be configured to detect an improper energy transmission configuration therein. The condition may be detected by way of a detection of a condition where an energy-transmitting electrode of the medical device system becomes too close to or becomes in contact with an object resulting in an inability of the electrode to properly transmit energy. For example, if the energy-transmitting electrode is a first electrode configured in its operational state to transmit energy to bodily tissue adjacent the first electrode, but the first electrode is inadvertently contacting a second electrode, such contact may cause at least some energy transmitted by the first electrode to follow an unintended path away from its intended path to the adjacent tissue. Such a condition may be detected based at least upon an analysis of information acquired from a sensing device system.
