Implantable leadless cardiac device with flexible flaps for sensing
First Claim
1. A subcutaneously implantable stimulation device comprising:
- an electrical stimulation and processing device comprising a housing defining an outer peripheral surface;
a flap member of flexible insulative material connected to the housing and projecting away from the housing;
a sensing device mounted on the flap member and spaced from the housing; and
a conductor electrically connecting the stimulator device and the sensing device;
wherein the flap member has an opening defined by a rim with a continuous edge;
wherein the housing has upper and lower members with matingly engageable upper and lower rims; and
wherein upon assembly of the upper and lower members the upper and lower rims engage and hold firm the rim of the flap member between the upper and lower members and fully seal the interior of the housing from the exterior environment.

Abstract
A technique for performing sensing operations in the body subcutaneously employs, in combination, the housing of an electrical stimulator such as a pacemaker or an implantable cardioverter defibrillator and an integral flap member of flexible insulative sheet material which has at least one arm projecting away therefrom to an extreme tip end. Each arm is rolled about itself from the tip end on a lateral axis transverse of the longitudinal axis of the arm into a compact unit adjacent the housing. An incision is made through the skin and a region beneath the skin enlarged to form a cavity. The compact unit is then inserted into the cavity and unrolled about the lateral axis of each arm so as to be laid flat under the skin. When positioned into a desired orientation, each flap member is sutured to the skin to maintain the desired orientation.
