Abstract

The present invention shows the use of a conducive electrode device (10) to actively treat or passively extinguish cardiac arrhythmias.

Claims

[Received by the International Bureau on 02 December 2003 (02.12.2003) : original claims 1-18; claims 1, 2 and 15 have been amended.
Claims 8, 9 and 10 have been deleted.
Claims 3-14 and 16-18 remain unchanged. (4 pages)]
What is claimed is:
1) An implantable medical device for insertion into a chamber of a patient's heart comprising: a radially expandable basket formed from a set of resilient wire loop elements coupled together at a distal tip. and coupled together at a proximal tip, said basket having a substantially rounded shape when deployed to conform to the shape of a heart chamber; each wire element being mechanically and electrical coupled to all other wire elements at the distal and /or proximal tip. thereby forming an approximately balloon shaped electrically conductive network positioned in contact with an atrial or ventricular surface upon insertion and deployment, whereby low voltage low current energy arising in the tissues or impressed on the tissues are distributed over the tissues in contact with the conductive network.
2) An implantable medical device for insertion into a chamber of a patient's heart comprising: a radially expandable basket formed from a set of resilient wire loop elements coupled together at a distal tip, and coupled together at a proximal tip, said basket having a substantially rounded shape when deployed to conform to the shape of a heart chamber; each wire element being mechanically and electrical coupled to all other wire elements at the distal and /or proximal tip, thereby forming an approximately balloon shaped electrically conductive network positioned in contact with an atrial or ventricular surface upon insertion and deployment; a plurality of annular wire rings positioned at orthogonal angles to said resilient wire loop elements, thereby forming a mesh network thereby connecting all of the elements of the network and bringing them to the same potential.
3) The device of claim 1 or claim 2 further comprising; a catheter body having a distal end coupled to said basket at said proximal tip of said basket or mesh for electrically coupling said set of resilient wire elements to a remote rhythm management device; said catheter body having a proximal end terminated in a pacing connector; said basket or mesh, thereby functioning as a distal electrode for said rhythm management device.
4) The device of 3 further comprising; a proximal ring electrode located on the body of the catheter proximate said catheter body distal end, said ring electrode being electrically independent of said mesh and separately terminated in said pacing connector.
5) The device of claim 3 or claim 4 further comprising: a rhythm management device coupled to said pacing connector for delivering a temporary or permanent therapy to the chamber containing said active basket or mesh.
6) The device of claim 5 further comprising: a passive basket or mesh located in a heart chamber for supplying a passive therapy in conjunction with the active therapy is the complimentary chamber.
7) The device of claim 5 wherein said rhythm management device delivers a therapy selected from the group of: sub-threshold stimulation pulses, super-threshold stimulation pulses, burst or other antitachycardia stimulation algorithm.
8) (canceled)
9) (canceled)
15 10) (canceled)
11) The device of claim 1 or claim 2 wherein at least one device is placed and deployed in a chamber selected from the group consisting of; the RV, the LV, the RA, the LA.
12) The device of claim 1 or claim 2 wherein at least two of said devices are placed and deployed in chambers selected from the group consisting of; the RV, the LV, the RA, the LA.
13) The device of claim 1 or claim 2 wherein at least three devices are placed and deployed in chambers selected from the group consisting of; the RV, the LV, the RA, the LA.
14) The device of claim 1 or claim 2 wherein one of said devices is placed and deployed in each chamber of the heart namely; the RV, the LV, the RA, the LA.
15) A medical device for insertion and implantation into a vessel in the pulmonary outflow tract comprising: a metallic mesh of resilient wires having a stent-like shape providing electrical and mechanical contact with cardiac endocardial surfaces, thereby preventing the initiation of atrial or ventricular arrhythmias.
16) An implantable medical device for application into a chamber of a patient's heart comprising: a radially expandable basket formed from a set of resilient wire elements coupled together at a distal tip, said basket having a substantially hemispheric shape when, deployed to conform to the shape of a heart chamber; each wire element being mechanically and electrical coupled to all other wire elements at the distal tip, thereby forming an
16 approximately hemispheric surface shaped electrically conductive mesh or mesh positioned in contact with an interior or exterior surface of the heart; a screw anchor coupled to said distal tip for retaining said mesh in contact with cardiac tissues.
17) The device of claim 16 wherein said device is positioned in contact with an epicardial surface upon deployment.
18) The device of claim 16 wherein said device is positioned in contact with an endocardial surface upon deployment.
