Low insertion force electrical connector for implantable medical devices

摘要

A low-insertion force electrical connector for implantable medical devices includes a housing with a pair of opposing sidewalls each with center openings oriented generally concentrically around a center axis. An inner coil is located in a recess with a coil axis generally co-linear with the center axis of the center openings. The inner coil includes an outer diameter less than a recess diameter, and an inner diameter greater than a center opening diameter. An outer coil is threaded onto the inner coil. The outer coil has an outer diameter less than the recess diameter, and an inner diameter less than the center opening diameter. The outer coil is radially expanded within the recess in response to engagement with contact rings on the implantable medical device, such that the outer diameter of the outer coil is at least equal to the recess diameter.

主权项

1. An electrical contact for coupling to a contact ring on an implantable medical device, the electrical contact comprising:
a housing with a pair of opposing sidewalls, each with center openings oriented generally concentrically around a center axis, the housing including a recess and a first protrusion disposed within the recess to at least partially divide the recess; and at least a pair of first coils disposed within the recess and separated from one another by the first protrusion, at least a portion of each of the first coils extending into the center openings, the portion of each of the first coils being configured to flex outwardly with insertion of the contact ring within the electrical contact.
