Tool for insertion of implanatable monitoring device and method
First Claim
1. A system for locating the appropriate insertion positioning for an implantable device having two electrodes for monitoring an ECG in a body such that use of said system indicates the substantially optimum ECG monitoring position for implant prior to implant in a non-invasive manner, said system having electrode means for measuring ECG signals on the surface of a body, means for moving the electrodes to various other positions on the body and means for comparing the ECG output signal at said various locations.

Abstract
A minimally invasive implant, means for insertion, and description of how to most efficiently use it are described n several embodiments. This implant preferably has a segmented looping memory for storing triggered physiologic events. Preferred events for setting autotriggers to record physiologic signals occurring during events include arrhythmias and syncopal events. Preferably the device can function without a microprocessor. An outside device or other patient activated manual trigger is included. Auto triggers and manually set triggers may be of different sizes. The preferred physiologic events are ECG signals. Electrode spacing can be critical. Additional sensors may be provided to the device. Preferred communications with the device is through telemetry such as is used for pacemakers and other implanted devices.
