LEAD ENGAGEMENT DEVICES AND METHODS FOR ELECTRICAL STIMULATION AND/OR MONITORING SYSTEMS

摘要

According to aspects of the present disclosure, an implantable electrical system may include an implantable pulse generator with a bore sized to receive an electrical lead, with an engagement mechanism that does not require the use of set screws to secure the lead within the bore. The engagement mechanism may include a deformable component that may be moved or deformed to allow entry of the lead into the bore, and then moved or deformed again to engage a surface of the lead to secure the lead within the bore. The engagement mechanism may allow rotation of the lead within the bore while maintaining electrical connections between the generator and the lead. The engagement mechanism may also allow the securing and/or release of the lead relative to the bore without the need to manipulate a set screw or breach a seal of the generator.

主权项

1. An implantable pulse generator comprising:
a housing having circuitry and a battery; and a header coupled to the housing, the housing including a bore configured to receive an end of a lead, the header supporting at least one electrical contact within the bore coupled to the circuitry, the header further supporting a retainer device within the bore, the retainer device having a first position that permits egress of the lead into the bore and having a second position that occludes at least a portion of the bore sufficiently to prevent egress of the lead from the bore.
