Adaptor for endovascular electrocardiography
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.
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.
