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.

[ What is claimed is:] [1.] A minimally invasive implant for implantation beneath a skin and into a living body comprising;a shell housing means having an inside and an outside,said outside forming a shape and having electrodes for sensing a physiologic parameter of said body, said electrodes located on said outside such that a substantially fixed spacing is maintained between said electrodes on said outside's shape, said electrodes being for electrical connection with the body and wherein said housing shape has a longitudinal dimension exceeding a transverse dimension, said transverse dimension being of a size suitable for insertion into said body with minimal opening requirements to the skin of said body, said minimal opening size being substantially no greater than 1/2 inch in maximum diameter,said inside having a power source and electronic circuitry powered thereby comprising at least an input means for sensing an electrical signal due to a physiologic parameter of said body connected to at least one of said electrodes, a memory means connected to accept output from said means for sensing, said memory means triggerable to use segments of said memory means by a trigger means and to store said output, as digital data representative of said physiologic parameter, and telemetry means connected to transmit data from said memory means upon activation of said telemetry means by a receiver means outside said body.
