1. An implantable medical device comprising:
a housing; and
a header arranged with the housing;
a connector port arranged within the header and configured to couple an implantable lead to the header, the connector port including a proximal end, an opposite distal end, and an access hole extending radially through the connector port between the proximal and distal ends of the connector port; and
a collet assembly arranged within the connector port and configured to clamp against a portion of the implantable lead and to secure the implantable lead with the header in response to insertion of the portion of the implantable lead into the connector port,
wherein the collet assembly includes one or more bearings arranged about an angled outer circumference of the collet assembly and configured to contact an angled inner circumference of the connector port, wherein the angled outer circumference of the collet assembly extends from a distal end of the collet assembly to a proximal end of the collet assembly, and wherein the one or more bearings are located between the distal end and the proximal end, and
wherein the access hole is aligned with the proximal end of the collet assembly and is configured to receive a probe for engaging the proximal end of the collet assembly to cause the collet assembly to move in an axial direction toward the distal end of the connector port.
