Abstract

This invention pertains generally to an implantable medical lead for stimulating muscle or tissue contraction and a method for using the same, and specifically to a paraneural electro-stimulating bipolar shielded lead and a method for using the same, for use in surgical procedures such as the Muscle Flap Heart Function Augmentation Procedure and/or other circulatory augmentation procedures, and/or wherever stimulation of muscle or tissue is desired.

Claims

1. A paraneural stimulating lead attached to stimulating means and which is spaced from a nerve of tissue to be stimulated, said paraneural lead comprising:

at least one first section comprising a bipolar, shielded lead which is spaced from said nerve of the stimulated tissue further comprising at least one shielded anode and at least one shielded cathode;

at least one second section comprising a connecting means for physically and electrically connecting said paraneural stimulating lead to said stimulating means;

a third section physically and electrically connecting said first section and said second section, said third section comprising a means for conducting a stimulating current discharge generated by said stimulating means between said first section and said second section; and

wherein the shielding of said shielded anode and said shielded cathode further comprises a means for attachment of said bipolar shielded lead to said tissue spaced from said nerve.

2. The paraneural stimulating lead of claim 1, wherein said stimulating means is a cardio-muscle stimulator and said paraneural stimulating lead is used for cardiac or circulatory augmentation including cardiomyoplasty.

3. The paraneural stimulating lead of claim 1, wherein said connecting means is a bipolar single unit connecting means providing both positive and negative connections in one unit.

4. The paraneural stimulating lead of claim 1 wherein said shielding further comprises a means for attachment of said bipolar shielded lead to a muscle flap.

5. The paraneural lead of claim 1, further comprising at least one anchoring sleeve positioned between said connecting means and said shielded anode and said shielded cathode.

6. A method of stimulating cardiac and non-cardiac tissue comprising:

contacting a paraneural stimulating lead with tissue to be stimulated;

connecting said paraneural stimulating lead to a stimulating means;

inducing said stimulating means to generate a stimulating current discharge;

transferring said stimulating current discharge to said tissue through said paraneural stimulating lead;

wherein said paraneural stimulating lead comprises at least one first section comprising a bipolar, shielded lead further comprising at least one shielded anode and at least one shielded cathode, at least one second section comprising a connecting means for physically and electrically connecting said bipolar shielded lead to said stimulating means, and a third section physically and electrically connecting said first section and said second section, said third section comprising a means for conducting a stimulating current discharge generated by said stimulating means between said first section and said second section.

8. The method of stimulating tissue of claim 6, wherein said contacting of said lead with said tissue is at the surface of said tissue spaced from the nerve of said tissue to be stimulated.

9. The method of stimulating tissue of claim 8, wherein said lead is attached to said tissue surface.

7. A method for use with cardiomyoplasty of stimulating tissue comprising:

contacting a paraneural stimulating lead with tissue to be stimulated;

connecting said paraneural stimulating lead to a stimulating means;

inducing said stimulating means to generate a stimulating current discharge;

transferring said stimulating current discharge to said tissue through said paraneural stimulating lead;

wherein said paraneural stimulating lead comprises a bipolar shielded lead further comprising at least one shielded anode and at least one shielded cathode, wherein the shielding of said shielded anode and said shielded cathode restricts the direction of flow of a stimulating current discharge so that said stimulating current discharge generated by said stimulating means flows unidirectionally into said tissue, said bipolar shielded lead further comprising a connecting means capable of physically and electrically connecting said bipolar shielded lead to said stimulating means, said bipolar shielded lead further comprising a means for electrically conducting said stimulating current discharge between said connecting means and said shielded anode and said shielded cathode.

10. The method of stimulating tissue of claim 7, wherein said contacting of said lead with said tissue is at the surface of said tissue spaced from the nerve of said tissue to be stimulated.

11. The method of stimulating tissue of claim 10, wherein said lead is attached to said tissue surface by said shield lead connecting means.

12. A method of stimulating tissue, for use with cardiac or circulatory augmentation including cardiomyoplasty, comprising:

contacting a paraneural stimulating lead with tissue to be stimulated;

connecting said paraneural stimulating lead to a stimulating means;

inducing said stimulating means to generate a stimulating current discharge;

transferring said stimulating current discharge to said tissue through said paraneural stimulating lead;

wherein said paraneural stimulating lead comprises a bipolar shielded lead further comprising at least one shielded anode and at least one shielded cathode, wherein the shielding of said shielded anode and said shielded cathode restricts the direction of flow of a stimulating current discharge so that said stimulating means flows unidirectionally into said tissue, sad bipolar shielded lead further comprising a connecting means capable of physically and electrically connecting said bipolar shielded lead to said stimulating means, said bipolar shielded lead further comprising a means for electrically conducting said stimulating current discharge between said connecting means and said shielded anode and said shielded cathode.

13. The method of stimulating tissue of claim 12, wherein said contacting of said lead with said tissue is at the surface of said tissue spaced from the nerve of said tissue to be stimulated.

14. The method of stimulating tissue of claim 13, wherein said lead is attached to said tissue surface by said shield lead connecting means.
