Abstract
Abstract An expandable electrode for location within a blood vessel or other tubular organ. The electrode takes the form of a hollow, tubular metal structure, expanded into contact with the inner walls of the tubular structure in which the electrode is to be located. Expansion of the electrode may take place by means of plastic deformation of the electrode, or the electrode may be fabricated such that it resiliently expands. The electrode is particularly adapted for location within arteries and veins, and in particular for use in the coronary sinus and great vein of the human heart.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
174 words
A method of inserting an electrode into a desired tubular organ within the body, said tubular organ having an inner surface defining an inner diameter, comprising: selecting a resiliently deformable electrode which in an undeformed state takes the form of a hollow elongated conductive cylinder defining a central lumen through said electrode and which in said undeformed state has an outer diameter greater than the inner diameter of said tubular organ; deforming said electrode to display an outer diameter less than the inner diameter of said tubular organ; mounting said deformed electrode to an introducer catheter comprising means for retaining said electrode and for maintaining the outer diameter of said electrode less than the inner diameter said tubular organ; inserting said electrode into said tubular organ at a desired location; and removing said electrode from said catheter and allowing said electrode to expand into contact with the inner surface of said tubular organ such that the lumen through said electrode has an inner diameter approximately equal to the inner diameter of said tubular organ.
Claim 2
Independent Claim
174 words
A method of inserting an electrode into a desired tubular organ within the body, said tubular organ having an inner surface defining an inner diameter, comprising: selecting a resiliently deformable electrode which in an undeformed state takes the form of a hollow elongated conductive cylinder defining a central lumen through said electrode and which in said undeformed state has an outer diameter greater than the inner diameter of said tubular organ; deforming said electrode to display an outer diameter less than the inner diameter of said tubular organ; mounting said deformed electrode to an introducer catheter comprising means for retaining said electrode and for maintaining the outer diameter of said electrode less than the inner diameter said tubular organ; inserting said electrode into said tubular organ at a desired location; and removing said electrode from said catheter and allowing said electrode to expand into contact with the inner surface of said tubular organ such that the lumen through said electrode has an inner diameter approximately equal to the inner diameter of said tubular organ.
Claim 3
Dependent Claim
29 words
A method according to claim 1 wherein said step of inserting said electrode into said desired tubular organ comprises inserting said electrode into a blood vessel within said body.
Claim 4
Dependent Claim
29 words
A method according to claim 2 wherein said step of inserting said electrode into said desired tubular organ comprises inserting said electrode into the coronary sinus within said body.
Claim 5
Dependent Claim
77 words
An implantable electrical lead, comprising: an elongated insulated electrical conductor having a proximal end and a distal end; a resiliently deformable electrode which in an undeformed state takes the form of a hollow cylinder having a central lumen extending therethrough mounted to the distal end of said conductor and extending distally therefrom, said electrode compressible from a first configuration displaying a first outer diameter in said undeformed state to a second configuration displaying a decreased outer diameter.
Claim 6
Dependent Claim
77 words
An implantable electrical lead, comprising: an elongated insulated electrical conductor having a proximal end and a distal end; a resiliently deformable electrode which in an undeformed state takes the form of a hollow cylinder having a central lumen extending therethrough mounted to the distal end of said conductor and extending distally therefrom, said electrode compressible from a first configuration displaying a first outer diameter in said undeformed state to a second configuration displaying a decreased outer diameter.
Claim 7
Dependent Claim
26 words
An electrode lead according to claim 4 further comprising a delivery catheter having means for retaining said electrode resiliently compressed to display said first outer diameter.
Claim 8
Dependent Claim
19 words
An electrical lead according to claim 4 wherein said electrode comprises an electrode formed entirely of a conductive material.
Claim 9
Dependent Claim
18 words
An implantable electrical lead according to claim 6 wherein said electrode is fabricated entirely of a conductive metal.
Claim 10
Dependent Claim
16 words
An electrical lead according to claim 4 wherein said electrode is fabricated of conductive metal wire.
