1. A method for treatment of disorders in the heart rhythm regulation system, said method comprising:
- inserting a tissue lesion creating device having a tubular cutting framework through the vascular system to a desired position in a vessel, andchanging a shape of the tissue lesion creating device at said desired position by radially expanding an entirety of said tubular cutting framework of said device to cut entirely through an outer circumference of a vessel wall into heart tissue surrounding said vessel.

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.

9. A method for treating heart rhythm disorders comprising:
-
advancing a treatment device having a tubular cutting framework through a vascular system and into a beating heart; releasing said treatment device at a treatment site within said beating heart; allowing said tubular cutting framework of said treatment device to expand against tissue of said beating heart; cutting said tissue of said beating heart with said tubular cutting framework of said treatment device by radially expanding an entirety of said tubular cutting framework of said treatment device to cut entirely through an outer circumference of said tissue of said beating heart; and
,forming scar tissue at said treatment site that reduces transmission of electrical signals through said tissue of said beating heart. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method for treatment of disorders in the heart rhythm regulation system, said method comprising:
-
inserting a tissue lesion creating device having a tubular cutting framework through a vascular system until a portion of said tissue lesion creating device is adjacent a heart; modifying a configuration of said tissue lesion creating device by radially expanding an entirety of said tubular cutting framework of said device to press against and cut entirely through an outer circumference of tissue of said heart. - View Dependent Claims (17, 18, 19, 20)
