Abstract
The epicardial pacing system and related method includes an epicardial catheter configured to be disposed in the middle mediastinum of the thorax of a subject for use in electrical pacing of the heart at one or more locations on the epicardial surface. The epicardial pacing catheter may include at least one electrode whereby the electrode is insulated on at least one side to allow pacing of the heart without damage to adjacent anatomical structures.
Claims5
An epicardial pacing system, said system comprising:
- an epicardial pacing catheter configured to be disposed in the body of a subject and configured for use in electrical pacing of the heart in at least three locations on the epicardial surface, said epicardial pacing catheter including:
- a proximal portion, a distal portion, and a longitudinal structure there between, wherein the proximal portion, the distal portion, and the longitudinal structure have requisite flexibility for deployment within the subject;
- a plurality of electrodes in communication with said distal portion;
- a stabilizer including deployable members configured to transition between a retracted position and a deployed position via a hinge device while disposed in the body of the subject, wherein the deployable members comprise at least one outward facing bumper tab and at least one inward facing friction tab and wherein the at least one inward facing friction tab exposes a lubricious surface when in the retracted position and further exposes a textured surface when transitioned to the deployed position, wherein the textured surface of the at least one inward facing friction tab comprises a rough surface having a larger coefficient of friction than the lubricous surface;
- and
- stabilizer actuators configured to allow an operator of said epicardial pacing system to deploy said deployable members, wherein the stabilizer actuators each include a longitudinal member that is in communication with the hinge device and is configured to deploy a corresponding deployable member of the deployable members to the deployed position via the hinge device.
