Abstract

An implantable medical device includes an impulse generator having a header and a contact assembly which includes at least one molded plastic housing having two halves joined together with the halves defining a bore therethrough. A canted coil spring is disposed within the housing halves along a bore circumference and includes a weld plate which extends to an exterior of the housing halves. A weld plate overlays the housing halves exterior which is joined to both the spring lead and devices wires.

Claims

1. An implantable medical device comprising:

an impulse generator having a header; and

at least one contact assembly disposed within said header and including;

at least one molded plastic housing including two halves joined together, the joined halves defining a bore therethrough;

a canted coil spring disposed within the housing halves along a bore circumference;

an exterior weld plate overlaying and aligning the housing halves and joined to the spring; and

at least one device wire joined to said weld plate.

2. The assembly according to claim 1 further comprising a plurality of molded plastic housings engaged with one another and aligned with coaxially bores each of the plurality including a canted coil spring with a weld plate extending to an exterior of the corresponding housing and joined thereto.

3. The assembly according to claim 2 further comprising a plurality of device wires, each device wire joined to a corresponding weld plate.

4. The assembly according to claim 3 further comprising an implantable lead insertable into the coaxial bores and having spaced apart conductive rings alignable with corresponding canted coil springs.

5. The assembly according to claim 1 wherein said weld plate is fixed to the housing halves by dovetails formed therein.

6. An implantable medical device comprising:

an impulse generator having a header; and

at least two parallel contact assemblies disposed within said header each assembly including;

a plurality of molded plastic housings each having including two halves joined together, the joined halves define a bore therethrough;

a canted coil spring disposed within each of the housing halves along a bore circumference;

an exterior weld plate overlaying and aligning pairs of the housing halves and joined to the spring; and

at least one device wire joined to each weld plate.

7. The assembly according to claim 6 wherein the plurality of molded plastic housings are aligned with coaxially bores.

8. The assembly according to claim 7 further comprising a plurality of device wires, each device wire joined to a corresponding weld plate.

9. The assembly according to claim 8 further comprising a pair of implantable leads insertable into corresponding coaxial bores and having spaced apart conductive rings alignable with corresponding canted coil springs.

10. The assembly according to claim 6 wherein said weld plate is fixed to the housing halves by dovetails formed therein.
