First Claim
Patent Images
1. A housing for an implantable defibrillator for implantation in the pectoral region of a patient, the housing comprising:
- at least two discrete, cooperating housing segments constructed of a biocompatible material, the segments positioned such that an edge of one segment is proximate to and coaxial with an edge of the other segment, and such that the segments define an integrated, articulated housing structure having a contoured periphery, wherein the segments are adapted to pivot at at least one hinge axis located between said segments, whereby the housing is configured to conform to the contour of an implantation site in the pectoral region of the patient'"'"'s chest and to flex in compliance with movement at said implantation site through pivotal movement of said segments, one relative the other, about said hinge axis.

Abstract
An implantable device, such as a defibrillator, has a conforming housing that is adapted to follow to the contours of the patient'"'"'s body at a device implantation site, while complying with pressures applied to the patient'"'"'s body and with body flexion. In one form of the invention, the device housing is articulated at one or more hinge locations to provide a segmented housing that conforms to an implantation site through movement about the hinge axis. Another embodiment of the invention provides a flexible housing that surrounds a flex-circuit assembly.
