Benefits of technology

[0016] According to an aspect of the invention, there is provided a tissue lesion creating device for reducing undesired signal transmission in heart tissue. The device is structured and arranged to be inserted through the vascular system into a body vessel adjacent the heart and to be subsequently subjected to a change of shape in order to penetrate into said heart tissue.
[0062] The method may further comprise releasing a restrain on the tissue lesion creating device when it has been inserted into the desired position for allowing said change of the shape of the tissue lesion creating device. The restrain may be released by withdrawing a tube holding the tissue lesion creating device in an insertion shape or by suspending the cooling of the tissue lesion creating device. This release may control the initiation of the change of shape of the tissue lesion creating device.

Problems solved by technology

This may be done through the vascular system, making the insertion only slightly invasive.
The tissue will then be replaced by fibrous tissue, which is not able to transmit electrical signals.

Embodiment Construction

[0088] Referring now to FIGS. 1-3, the problems of disorders to the heart rhythm regulation system and the leading current method of treating these problems will be described. In FIG. 1, a heart 2 is shown and the controlling of the heart rhythm is indicated. The heart rhythm is normally controlled from the sinoatrial node 4. The sinoatrial node 4 transmits electrical signals which are propagated through the heart wall by means of special cells forming an electrical pathway. The electrical signals following the electrical pathway will coordinate the heart muscle cells for almost simultaneous and coordinated contraction of the cells in a heart atrium and heart ventricle. The normal conduction of electrical impulses through the heart starts in the sinoatrial node 4, travels across the right atrium, the atrioventricular node 5, the bundles of His 6 and thereafter spread across the ventricular muscle mass. In a disordered situation, electrical signals are started in heart cells outside ...

Abstract

A tissue lesion creating device is structured and arranged to be inserted through the vascular system into a body vessel adjacent the heart and to be subsequently subjected to a change of shape in order to penetrate into the heart tissue. The tissue lesion creating device may thus be used for treating disorders to the heart rhythm regulation system. A kit of devices provides a plurality of devices for creating a lesion pattern for treating such disorders.

Description

FIELD OF THE INVENTION [0001] The present invention relates to treatment of disorders in the heart rhythm regulation system and, specifically, to a tissue lesion creating device, a kit of shape-changing devices and a method for treating such disorders. BACKGROUND OF INVENTION [0002] The circulation of blood in the body is controlled by the pumping action of the heart. The heart expands and contracts by the force of the heart muscle under impulses from the heart rhythm regulation system. The heart rhythm regulation system transfers an electrical signal for activating the heart muscle cells. [0003] The normal conduction of electrical impulses through the heart starts in the sinoatrial node, travels across the right atrium, the atrioventricular node, the bundles of His and thereafter spread across the ventricular muscle mass. Eventually when the signal reaches the myocytes specialized in only contraction, the muscle cell will contract and create the pumping function of the heart (see F...
