CARDIAC STIMULATION APPARATUS
First Claim
1. Cardiac stimulation apparatus comprising an electrode support, an electrode provided on the support for electrical contact with internal tissue within the body of a patient, and means for releasably attaching the support in position in relation to the internal tissue, an electrical lead defining an electroconductive path for delivering stimulation to the electrode, the support being forcibly removable from the internal tissue and also collapsible upon application of a pulling force to the electrical lead to facilitate withdrawal of the support from the body of the patient along with the electrical lead.

Abstract
Cardiac stimulation apparatus (10) such as a lead comprising one or more electrodes (17, 19 and 21) for electrical contact with heart or other tissue. An adhesive substance is provided for adhesively attaching the electrodes in position in relation to the heart or other tissue to provide a non-traumatic fixing procedure. The electrodes (17, 19, 21) are positioned on a support (15) to which the adhesive substance is applied attached.

- 1. Cardiac stimulation apparatus comprising an electrode support, an electrode provided on the support for electrical contact with internal tissue within the body of a patient, and means for releasably attaching the support in position in relation to the internal tissue, an electrical lead defining an electroconductive path for delivering stimulation to the electrode, the support being forcibly removable from the internal tissue and also collapsible upon application of a pulling force to the electrical lead to facilitate withdrawal of the support from the body of the patient along with the electrical lead.
- 6. A cardiac stimulation lead comprising an electrode support at one end of the lead, first and second electrodes mounted in spaced relation on the electrode support, and a third electrode mounted on the electrode support in spaced relation to said first and second electrodes, said first and second electrodes being dimensioned for cardiac pacing and the third electrode having a larger electrical contact area than the first and second electrodes for cardiac defibrillation, and means for providing an electroconductive path between each electrode and the other end of the lead for electrical connection to a source of electrical stimulation, means for releasably attaching the support in position in relation to internal tissue within the body of a patient, the support being forcibly removable from the internal tissue and also collapsible upon application of a pulling force to the cardiac stimulation lead to facilitate withdrawal of the support from the body of the patient.
-
18. An epicardial stimulation lead, comprising:
- an elongated sheath, an electrode support at one end of the sheath and an electrode mounted on the electrode support, an electroconductive path passing through the sheath between the electrode and the other end of the sheath, wherein the sheath comprises a ribbon of flexible material twisted about its length.

-
21. A method of making a stimulation lead comprising the steps of providing a ribbon of flexible material and an electrode support at one end of the ribbon, providing an electrode on the electrode support, forming an electroconductive path along the ribbon from the electrode to the other end of the ribbon, and twisting the ribbon about its length to create a sheath for housing the electroconductive path.
- 22. A biomedical device comprising a substrate supporting an electrode, the substrate being attachable to internal tissue of a patient, the electrode being detachable from the substrate for removal from the patient while the substrate remains attached to the internal tissue, the substrate comprising a bioabsorbable material.
