Abstract
Some embodiments of an electrode delivery system may be used to deliver a plurality of wired electrodes into one or more chambers of the heart. In particular embodiments, the plurality of wired electrodes may be delivered into a heart chamber through a single guide sheath device. Such a system may be used to deliver one or more wired electrodes to inner wall of the left atrium, the left ventricle, or both.
Claims15
A system, comprising:
- a cardiac stimulation wired electrode assembly, comprising:
- a fixation device configured to be driven in a direction of a longitudinal axis of the fixation device to securely implant the fixation device into an interior wall of a heart chamber, the fixation device comprising a conductive helical coil member having a piercing tip at a distal end and an integrally formed cross bar extending inward at a proximal end of the coil member toward the center of the coil member to form a handle;
- and
- at least one insulated wire including a first end that is attached directly to the conductive material of the fixation device at an attachment point that is laterally offset from the longitudinal axis of the fixation device, and including a second end that is connectable to an implantable pulse generator device;
- and
- wherein the fixation device handle is confined within a lateral profile of the fixation device, the handle member configured to be releasably retained by a deployment device at a first location, and wherein the insulated wire is laterally offset from the deployment device and the first location when the handle member is releasably retained by the deployment device at the first location.
