Device, a kit and a method for treatment of disorders in the heart rhythm regulation system

摘要

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.

主权项

1. A kit of shape-changing devices for treatment of disorders in a heart rhythm regulation system, said kit comprising:
shape-changing devices, which each has a first and a second state, wherein the device in the first state has such dimensions as to be insertable to a desired position within the vascular system, and wherein the device is capable of changing shape to the second state when located at said desired position, the device in the second state having a tubular part, which strives to a diameter that is larger than the diameter of the vessel at the desired position, whereby the tubular part has expansion characteristics so as to circumferentially cut through an entire vessel wall of said vessel along an entire circumference and along a length of the tubular part into a tissue surrounding the vessel at the desired position and destroy the tissue in order to prevent the tissue from transmitting electrical signals, wherein at least one of the shape-changing devices is adapted to be inserted to a position at an orifice of a pulmonary vein in a heart, and at least one of the shape-changing devices is adapted to be inserted to a position in a coronary sinus.
