Abstract

An ECG lead set including an ECG electrode assembly and a lead set hub. ECG electrode includes at least one electrode configured to receive biopotential signals from a patient, a plug connector for connecting said ECG electrode assembly, a web, connected between the at least one electrode and the plug connector and configured to form an electrical connection therebetween. The lead set hub includes at least one receptacle configured to receive the plug connector of the ECG electrode assembly.

Claims

1. A lead set assembly comprising:

a lead set hub adapted for electrical connection to a biomedical device;

at least one electrode lead, the at least one electrode lead including;

a lead member;

a flexible tail forming a first end of the lead member and including a continuous conductive strip along the length thereof, the flexible tail configured to releasably connect to the lead set hub; and

an electrode at a second end of the lead member for receiving biopotential signals from a patient, the biopotential signals being transmittable from the electrode to the lead set hub through at least a portion of the continuous conductive strip in the flexible tail, the biopotential signals being transmittable through the lead set hub to provide biomedical information to the biomedical device;

a plate mounted to the lead set hub for electrical connection to the biomedical device; and

a clamp mounted to the lead set hub, the clamp having a receptacle for reception of the flexible tail of the lead member, the clamp movable from an initial unclamped position to a clamped position thereby causing the clamp to secure the flexible tail of the lead member and the plate to puncture the lead member to electrically connect the continuous conductive strip to the plate thereby establishing an electrical connection between the electrode and the lead set hub.

2. The lead set assembly according to claim 1, wherein the clamp includes a conductive terminal adapted to electrically contact a portion of the continuous conductive strip of the flexible tail upon movement of the clamp to the clamped position.

3. The lead set assembly according to claim 2, wherein the lead member includes an insulating cover adapted to electrically isolate the continuous conductive strip and wherein the clamp includes a penetrating member adapted to penetrate the insulating cover upon movement of the clamp to the clamped position to permit the conductive terminal to electrically contact the portion of the continuous conductive strip.

4. The lead set assembly according to claim 3, wherein the penetrating member is adapted to sever the flexible tail upon movement of the clamp to the clamped position.

5. A lead set assembly, comprising:

an electrode assembly including;

an electrode configured to receive biopotential signals from a patient; and

a flexible tail including a continuous conductive strip extending along a length thereof, the continuous conductive strip electrically connectable to the electrode, the flexible tail having a first layer configured to insulate the continuous conductive strip and a second layer with the continuous conductive strip disposed therebetween; and

a lead set hub including a receptacle configured to receive the flexible tail of the electrode assembly, the receptacle having a clamp dimensioned to establish a conductive terminal and adapted to electrically connect the continuous conductive strip of the flexible tail of the electrode assembly to the lead set hub upon movement of the clamp from an initial unclamped position to a clamped position, wherein moving the clamp from the unclamped position to the clamped position causes the clamp to apply pressure to the first layer of the flexible tail to secure the flexible tail to the lead set hub and to puncture the second layer of the flexible tail to electrically connect the continuous conductive strip to the lead set hub thereby establishing an electrical connection between the electrode and the lead set hub.

6. The lead set assembly according to claim 5, wherein the second layer comprises an insulating cover that electrically insulates the continuous conductive strip of the flexible tail, and the clamp further includes a penetrating member connected to the clamp and adapted to penetrate the insulating cover upon movement of the clamp to the clamped position thereby forming an electrical connection with the electrode of the electrode assembly.

7. The lead set assembly according to claim 6, wherein the penetrating member is adapted to sever at least a portion of the electrode assembly upon movement of the clamp to the clamped position.

8. A lead set assembly comprises:

an electrode assembly including a tab portion and a flexible tail, the electrode assembly comprising;

a conductive

disposed on at least a portion of the tab and at least a portion of the center of the flexible tail and extending along the length of the flexible tail, the flexible tail having a first layer configured to insulate the conductive layer and a second layer with the conductive layer disposed therebetween;

a conductive adhesive layer disposed on the conductive layer and adjacent the tab portion; and

a lead set hub assembly

including;

a lead set hub; and

at least one clamp receptacle associated with the lead set hub, the clamp receptacle configured to receive the flexible tail, the clamp receptacle configured to pierce the second layer and electrically connect to the conductive layer of the electrode assembly when moved from an unclamped position to a clamped position, wherein moving the clamp from the unclamped position to the clamped position causes the clamp to apply pressure to the first layer to secure the flexible tail to the lead set hub, and to pierce the second layer of the flexible tail to electrically connect the conductive layer to the lead set hub thereby establishing an electrical connection between the electrode and the lead set hub.

9. The lead set assembly according to claim 8, wherein the conductive layer coated on the tab and the flexible tail is a conductive ink.

10. The lead set assembly according to claim 8, wherein the conductive layer covers a substantial portion of the tab.

11. The lead set assembly according to claim 8, wherein the conductive adhesive layer includes a hydrogel adhesive.

12. The lead set assembly according to claim 11, wherein the electrode assembly further includes a releasable liner releasably attached to the hydrogel adhesive.

13. The lead set assembly according to claim 8, wherein the electrode assembly further includes a nonconductive adhesive layer disposed on a portion of the flexible tail.
