A connector for connecting conductors of a medical electrical lead with an implantable medical device, the connector comprising:
- a connector body having multiple conductors;
- and
- a modular system of connector blocks for routing and joining the conductors of the lead with the conductors of the connector body.
A connection system for connecting a plurality of electrical conductors of a medical electrical lead to a plurality of conductors of a connector that is insertable into an implantable medical device, the connection system comprising:
- a plurality of connector blocks, each block comprising:
- a first tooth positioned on the outer diameter of the block for receiving one of the plurality of conductors from the connector;
- and
- a second tooth positioned on the outer diameter of the block approximately one hundred eighty degrees from the first tooth and for receiving one of the plurality of conductors from the lead;
- wherein the plurality of connector blocks are axially aligned in a connector housing and circumferentially rotated with respect to one another.
A medical electrical lead connector comprising:
- a connector body having a proximal end for insertion into an implantable medical device and a distal end for connecting with a medical electrical lead, the connector body comprising a generally cylindrical connector body having a central channel running through the axis of the connector body;
- a first connector ring positioned near a proximal end of the connector body;
- a first conductor wire embedded in the connector body and extending from the distal end to the first connector ring, and conductively linked with the first conductor;
- and
- a retainer comprising:
- a cylindrical body having a proximal end for inserting in the central channel;
- a distal end for receiving a medical electrical lead conductor;
- and
- a center bore extending from the distal end to the proximal end.
A medical lead connector for connecting a lead with an implantable medical device comprising:
- a connector body having a plurality of conductors integrally formed with the connector body;
- and
- a central bore for receiving a conductor.
A retention system for use in a medical electrical lead including a connector pin and a connector body, the retention system comprising:
- a collar comprising:
- an inner diameter sized to match an outer diameter of a groove in the connector pin;
- and
- an outer diameter sized to engage a slot in the connector body;
- and a key for lockably engaging the inner diameter of the collar such that the key is prevented from disengaging the collar.
