Abstract

A connector sleeve includes a lumen adapted to receive a medical lead connector wherein a retention element engages a retention edge formed at a distal end of a connector element included on the lead connector. The connector sleeve further includes a contact element adapted to electrically engage the lead connector element within the lumen and an external conductive surface electrically coupled to the contact element and adapted for electrical engagement within the connector bore of an implantable medical device.

Claims

1. A medical system comprising:

an implantable medical device including a connector bore;

an electrical lead connector including a connector element;

the connector element comprising a portion defining a retention edge with an engagement surface extending laterally to a centerline axis of the connector element; and

a connector sleeve including

a lumen adapted to receive the lead connector,

a contact element within the connector sleeve lumen adapted to electrically engage the connector element,

a retention element extending into the sleeve lumen, the retention element deflectable during insertion of the electrical lead connector into the connector sleeve lumen and redeploying to its initial position to mechanically engage the retention edge surface of the connector element portion and retain the connector element within the connector sleeve lumen and

an external conductive surface electrically coupled to the contact element and adapted for electrical engagement within the connector bore of the implantable medical device.

2. The medical system of claim 1, wherein the connector sleeve further includes a sidewall and the retention element comprises a deflectable clip ring having opposing ends protruding into the lumen through the sidewall to mechanically abut the retention edge surface of the connector element within the lumen of the connector sleeve.

3. The medical system of claim 1, wherein the retention element of the connector sleeve and the contact element of the connector sleeve are integrally formed.

4. A medical electrical lead adaptor assembly, comprising:

a lead connector adapted to be coupled to a medical electrical lead and having a connector element comprising a portion defining a retention edge with an engagement surface extending laterally to a centerline axis of the connector element;

a connector sleeve having a lumen adapted to receive a lead connector;

a contact element within the sleeve lumen adapted to electrically engage a connector element of the lead connector

a retention element extending into the sleeve lumen and deflecting during insertion of the lead connector into the connector sleeve lumen and redeploying to its initial position to mechanically engage the retention edge surface of the connector element portion and retain the lead connector within the connector sleeve lumen; and

an external conductive surface on the connector sleeve electrically coupled to the contact element and adapted for electrical connection to an implantable medical device.

5. The medical lead adaptor assembly of claim 4, wherein the connector sleeve further comprises a sidewall and wherein the retention element comprises a deflectable clip ring having opposing ends protruding into the lumen through the sidewall.

6. The medical lead adaptor assembly of claim 4, wherein the retention element and the contact element are integrally formed.

7. A medical system comprising:

an implantable medical device including a connector bore;

an electrical lead connector including a connector element;

the connector element comprising a portion defining a laterally extending retention edge; and

a connector sleeve including

a lumen adapted to receive the lead connector,

a contact element within the connector sleeve lumen adapted to electrically engage the connector element,

a retention element extending into the sleeve lumen, the retention element deflectable during insertion of the electrical lead connector into the connector sleeve lumen and redeploying to its initial position to mechanically engage the retention edge of the connector element portion and retain the connector element within the connector sleeve lumen and

an external conductive surface electrically coupled to the contact element and adapted for electrical engagement within the connector bore of the implantable medical device.

8. The medical system of claim 7, wherein the connector sleeve further includes a sidewall and the retention element comprises a deflectable lever formed in the sidewall to mechanically abut the retention edge surface of the connector element within the lumen of the connector sleeve.

9. The medical system of claim 7, wherein the connector sleeve further includes a sidewall and the retention element comprises a deflectable clip ring having opposing ends protruding into the lumen through the sidewall to mechanically abut the retention edge surface of the connector element within the lumen of the connector sleeve.

10. The medical system of claim 7, wherein the retention element comprises a resilient protrusion.

11. The medical system of claim 7, wherein the retention element of the connector sleeve and the contact element of the connector sleeve are formed integrally with one another.

12. A medical electrical lead adaptor assembly, comprising:

a lead connector adapted to be coupled to a medical electrical lead and having a connector element comprising a laterally extending retention edge;

a connector sleeve having a lumen adapted to receive a lead connector;

a contact element within the sleeve lumen adapted to electrically engage a connector element of the lead connector

a retention element extending into the sleeve lumen and deflecting during insertion of the lead connector into the connector sleeve lumen and redeploying to its initial position to mechanically engage the retention edge of the connector element portion and retain the lead connector within the connector sleeve lumen; and

an external conductive surface on the connector sleeve electrically coupled to the contact element and adapted for electrical connection to an implantable medical device.

13. The medical electrical lead adaptor assembly of claim 12, wherein the connector sleeve further comprises a sidewall and wherein the retention element comprises a deflectable lever formed in the sidewall to mechanically abut the retention edge surface of the connector element portion.

14. The medical lead adaptor assembly of claim 12, wherein the connector sleeve further comprises a sidewall and wherein the retention element comprises a deflectable clip ring having opposing ends protruding into the lumen through the sidewall.

15. The medical lead adaptor assembly of claim 13, wherein the retention element comprises a resilient protrusion.

16. The medical lead adaptor assembly of claim 13, wherein the retention element and the contact element are formed integrally with one another.
