SYSTEM FOR LEADLESS PACING OF THE HEART

摘要

Devices for use in providing stimulation to cardiac tissue are provided. One device is configured for implantation in or near the heart and includes a flexible, elongate body. The body is configured to be positioned across two different sections of the vasculature such that (a) the first end can be positioned in a first section of the vasculature through which the device can stimulate a first chamber of the heart and (b) the second end can be positioned in a second section of the vasculature through which the device can stimulate a second chamber of the heart. The device further includes a receiver circuit configured to receive signals wirelessly from a transmitter device and to convert the signals into electrical power. The device also includes at least a first set of one or more electrodes configured to stimulate the heart using the electrical power.

主权项

1. A device that is configured for implantation in a vasculature within or proximate to a heart of a patient so as to accommodate stimulation of at least one of a first chamber and a second chamber of the heart, respectively, the device comprising:
a flexible, elongated body that has a first end and an opposite second end, wherein the body has a substantially isodiametric tubular shape across a length of the body between the first end and the opposite second end, wherein the body is configured to be positioned across two different sections of the vasculature such that (a) the first end can be positioned in a first section of the vasculature through which the device can stimulate the first chamber of the heart and (b) the second end can be positioned in a second section of the vasculature through which the device can stimulate the second chamber of the heart; a receiver circuit configured to receive signals wirelessly from a transmitter device and to convert the signals into electrical power; and at least a first set of one or more electrodes that is positioned on the body proximate to the first end and that is configured to receive the electrical power from the receiver circuit and to stimulate the heart.
