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: 11
Claim 1
Independent Claim
140 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 an electrode taking the form of a hollow, elongated conductive cylinder defining a central lumen therethrough, said electrode displaying an outer diameter less than the innter diameter of said tubular organ; inserting said electrode into said tubular organ at a desired location; and expanding said electrode into contact with the inner surface of said tubular organ by permanently deforming said electrode by expanding said electrode from a first configuration in which the other diameter of said electrode is substantially less than the inner diameter of said tubular organ to a second configuration in which the lumen through said electrode has an inner diameter approximately equal to the inner diameter of said tubular organ.
Claim 2
Independent Claim
140 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 an electrode taking the form of a hollow, elongated conductive cylinder defining a central lumen therethrough, said electrode displaying an outer diameter less than the innter diameter of said tubular organ; inserting said electrode into said tubular organ at a desired location; and expanding said electrode into contact with the inner surface of said tubular organ by permanently deforming said electrode by expanding said electrode from a first configuration in which the other diameter of said electrode is substantially less than the inner diameter of said tubular organ to a second configuration in which the lumen through said electrode has an inner diameter approximately equal to the inner diameter of said tubular organ.
Claim 3
Dependent Claim
64 words
A method according to claim 1 wherein said step of inserting said electrode comprises mounting said electrode to a catheter having an expansible portion, such that the expansible portion of said catheter is located within said lumen through said electrode; and wherein said step of expanding said electrode comprises expanding said expansible portion of said catheter to accomplish said permanent deformation of said electrode.
Claim 4
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 5
Dependent Claim
29 words
A method according to claim 3 wherein said step of inserting said electrode into said desired tubular organ comprises inserting said electrode into the coronary sinus within said body.
Claim 6
Dependent Claim
89 words
An implantable electrical lead, comprising: an elongated insulated conductor having a proximal end and distal end; a hollow, cylindrical electrode formed of a permanently deformable material, mounted to the distal end of said conductor and extending distally therefrom, said cylindrical electrode having a central lumen extending therethrough, said cylindrical electrode expandable from a first configuration displaying a first outer diameter to a second configuration displaying an increased, second outer diameter wherein said electrode is adapted to be permanently deformed by expansion from said first diameter to said second diameter.
Claim 7
Dependent Claim
89 words
An implantable electrical lead, comprising: an elongated insulated conductor having a proximal end and distal end; a hollow, cylindrical electrode formed of a permanently deformable material, mounted to the distal end of said conductor and extending distally therefrom, said cylindrical electrode having a central lumen extending therethrough, said cylindrical electrode expandable from a first configuration displaying a first outer diameter to a second configuration displaying an increased, second outer diameter wherein said electrode is adapted to be permanently deformed by expansion from said first diameter to said second diameter.
Claim 8
Dependent Claim
41 words
An electrical lead according to claim 5 further comprising a delivery catheter having an expandable portion located thereon, wherein said electrode is mounted to said delivery catheter such that said cylindrical electrode is mounted around said expandable portion of said catheter.
Claim 9
Dependent Claim
21 words
An electrical lead according to claim 5 wherein said hollow, cylindrical electrode comprises an electrode formed entirely of a conductive material.
Claim 10
Dependent Claim
18 words
An implantable electrical lead according to claim 7 wherein said electrode is fabricated entirely of a conductive metal.
Claim 11
Dependent Claim
16 words
An electrical lead according to claim 5 wherein said electrode is fabricated of conductive metal wire.
