Abstract

A lead adapter is disclosed which includes a connector portion having a connector configured for reception by an electrical stimulation device and a receptacle portion electrically connected to the connector portion and having at least two receptacles for operatively accepting lead connectors, wherein at least one of the receptacles of the receptacle portion is configured to operatively accept a different type of lead connector than another receptacle of the receptacle portion.

Claims

1. A lead adapter comprising:

a) a connector portion including a bipolar IS-1 type lead connector configured for reception by an electrical stimulation device; and

b) a receptacle portion electrically connected to the connector portion and having two receptacles for operatively accepting lead connectors, wherein one of the receptacles of the receptacle portion is configured to operatively accept a bipolar IS-1 type lead connector and the other receptacle of the receptacle portion is configured to operatively accept a unipolar LV-1 type lead connector.

2. A lead adapter as recited in claim 1, wherein the lead adapter includes a main housing, and wherein the connector portion extends distally from the main housing and the receptacle portion is formed integral with a proximal portion of the main housing.

3. A lead adapter as recited in claim 1, wherein the lead adapter includes a medial yoke portion, and wherein the connector portion extends distally from the yoke portion and the receptacle portion extends proximally from the yoke portion.

4. A lead adapter comprising:

a) a yoke portion;

b) a connector portion extending distally from the yoke portion and including a bipolar IS-1 type connector configured for reception within a corresponding port of an electrical stimulation device; and

c) a bifurcated receptacle portion extending proximally from the yoke portion and electrically connected to the connector portion, the receptacle portion including a first receptacle configured to operatively accept a unipolar LV-1 type lead connector and a second receptacle configured to operatively accept a bipolar IS-1 type lead connector;

wherein each receptacle is connected to the yoke portion by an elongated flexible lumen.

5. A lead adapter as recited in claim 4, wherein one elongated flexible lumen is longer than the other elongated flexible lumen.

6. A lead adapter as recited in claim 5, wherein the elongated flexible lumen associated with the first receptacle is longer than the elongated flexible lumen associated with the second receptacle.

7. A lead adapter comprising:

a) a yoke portion;

b) a connector portion extending distally from the yoke portion and including a bipolar type connector configured for reception within a corresponding port of an electrical stimulation device;

c) a first receptacle portion configured to accept a unipolar type lead connector and connected to the yoke portion by a first elongated flexible lumen extending proximally from the yoke portion and having a first length; and

d) a second receptacle portion configured to accept a bipolar type lead connector and connected to the yoke portion by a second elongated flexible lumen extending proximally from the yoke portion and having a second length;

wherein the first receptacle portion is configured to accept a unipolar LV-1 type connector and the second receptacle portion is configured to accept a bipolar IS-1 type connector.

8. A lead adapter as recited in claim 7, wherein first receptacle portion is configured to operatively accept a unipolar type lead connector and the second receptacle portion is configured to operatively accept a bipolar type lead connector.

9. A lead adapter as recited in claim 8, wherein the length of the first elongated flexible lumen differs from the length of the second elongated flexible lumen.

10. A lead adapter as recited in claim 7, wherein the length of the first elongated flexible lumen is greater than the length of the second elongated flexible lumen.
