Abstract
Abstract A ribbon conductor set and related method of production and installation are provided for electrically interconnecting components in an implantable medical device, such as a heart pacemaker unit or the like. The ribbon conductor set is formed by die cutting and/or stamping a thin plate of conductive material to define a plurality of conductor ribbons supported from a frame. The ribbon set and supporting frame are shaped for seated placement into a fixture to orient the conductor ribbons in predetermined array to extend between electrical components on the fixture, such as between connector blocks and feedthrough terminals of a heart pacemaker unit. The fixture thus supports the conductor ribbons for facilitated connection to the electrical components, such as by welding, after which the resultant subassembly may be further processed as by encapsulation within a cast epoxy head or the like.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
150 words
An implantable stimulating device for stimulating a patient's heart, comprising: a battery; a pulse generator, coupled to the battery, for generating stimulating pulses to the patient's heart; a hermetically sealed housing for housing the battery and the pulse generator, the housing including a plurality of feedthrough terminal pins for connecting the pulse generator to the exterior of the housing; a plurality of connector blocks disposed external to the housing for securing at least one stimulation lead thereto; a plurality of conductor ribbons formed as a set in a predetermined number, shape and spacing, the conductor ribbons extending between respective ones of the connector blocks and the feedthrough terminal pins; and encapsulation means attached to the housing, the encapsulation means having the plurality of connector blocks and the plurality of conductor ribbons encapsulated therein, the encapsulation means further having at least one channel for receiving at least one stimulating lead therein.
Claim 2
Dependent Claim
150 words
An implantable stimulating device for stimulating a patient's heart, comprising: a battery; a pulse generator, coupled to the battery, for generating stimulating pulses to the patient's heart; a hermetically sealed housing for housing the battery and the pulse generator, the housing including a plurality of feedthrough terminal pins for connecting the pulse generator to the exterior of the housing; a plurality of connector blocks disposed external to the housing for securing at least one stimulation lead thereto; a plurality of conductor ribbons formed as a set in a predetermined number, shape and spacing, the conductor ribbons extending between respective ones of the connector blocks and the feedthrough terminal pins; and encapsulation means attached to the housing, the encapsulation means having the plurality of connector blocks and the plurality of conductor ribbons encapsulated therein, the encapsulation means further having at least one channel for receiving at least one stimulating lead therein.
