Abstract

An adaptor for endovascular electrocardiography includes a member having two ends and an inner lumen such that when one of the ends is connected to a catheter and the other end is connected to a syringe, fluid from the syringe is flushed into the catheter through the inner lumen. The adaptor also includes a metal insert, disposed along the inner lumen of the member, which connects through a sealed electrical connection to the outer side of the member.

Claims

1. An adaptor for endovascular electrocardiography, comprising:

a member having a first end, a second end, and an inner lumen, the first end designed to be connected to a luer of a catheter and the second end designed to be connected to a syringe, such that fluid from the syringe is flushed into the catheter through the inner lumen; and

a metal ring, disposed along the inner lumen of the member and located fully inside the member, the metal ring connecting through a sealed electrical connection to an outer side of the member, the metal ring separated from the catheter by a section of the member when the first end of the member is connected to the luer of the catheter.

2. The adaptor according to claim 1, wherein the metal ring comprises a metal ring disposed along an inner surface of the inner lumen.

3. The adaptor according to claim 1, wherein the metal ring terminates prior to the two ends of the member.

4. The adaptor according to claim 1, further comprising a wire having a first end connected to the metal ring.

5. The adaptor according to claim 4, further comprising a connector coupled to an opposing end of the wire.

6. The adaptor according to claim 5, wherein the connector comprises external insulation.

7. The adaptor according to claim 5, wherein the connector is configured to plug into an electronic module.

8. The adaptor according to claim 5, wherein the connector comprises a nipple shape.

9. The adaptor according to claim 1, wherein an exterior most surface of the one of the ends of the adaptor is tapered.

10. The adaptor according to claim 9, wherein the other end comprises a luer connector.

11. The adaptor according to claim 1, wherein a body portion provides a connection between the metal ring along an inner surface of the inner lumen of the member and a wire external to the member through a perforation in a wall of the member.

12. The adaptor according to claim 11, wherein the connection through the wall is waterproof.

13. The adaptor according to claim 1, wherein the two ends of the member comprise different external and internal diameters.

14. An assembly for endovascular electrocardiography, comprising:

the adaptor according to claim 1; and

a connector separate from a body of the adaptor coupled to the metal ring.

15. The assembly according to claim 14, wherein the connector is coupled to the adaptor by a wire between the metal ring and the connector, the wire configured to freely orient the connector with respect to the adaptor.

16. The assembly according to claim 14, wherein the connector is configured to plug into an electronic module.

17. The assembly according to claim 14, wherein the connector comprises a nipple shape.
