Abstract:
1. A device connector-to-lead terminal connector for an implantable medical device comprising: (a) an implantable pulse generator contained within a hermetically sealed housing; (b) a device connector affixed to a predetermined surface of said housing, the device connector having first and second side surfaces and a front surface and having at least one longitudinally extending bore formed inwardly from the front surface adapted to receive a proximal terminal of a medical lead therein, the proximal terminal including a conductive pin at a proximal end of the terminal; (c) an electrical contact disposed in the device connector and positioned to cooperate with the conductive pin when the proximal terminal of the medical lead is fully inserted into the longitudinal bore; (d) said device connector having first and second side ports extending inwardly from said first and second side surfaces to intersect with the longitudinal bore in alignment with the contact; (e) an elastomeric tube inserted through one of the first and second side ports and oriented crosswise to the longitudinally extending bore, the elastomeric tube having a central lumen and a radial flange on opposed ends of said tube; (f) a first latch member adapted to be inserted through the first side port, the first latch member including a pair of bifurcated legs extending into said lumen; and (g) a second latch member insertable through the second side port into said lumen and having a tapered wedge surface adapted to spread the bifurcated legs of the first latch member apart and press the elastomeric tube against the conductive pin with a force sufficient to hold the conductive pin in place against the electrical contact when the first and second latch members are squeezed together, the radial flanges forming moisture impervious seals between the first and second side surfaces of the device connector and the first and second latch members.
