    摘要： The invention provides a catheter and method of making the same including an first tubular member having a length, an outer surface, an inner surface and a lumen therein. The catheter also includes second tubular member having an outer surface, an inner surface and a lumen therein, at least a length of the second lumen is disposed in the lumen of the first tubular member. The catheter also includes a support member biasing a portion of the outer surface of the inner tubular member against a portion of the inner surface of the outer tubular member. The method of the invention includes providing a first tubular member and a second tubular member, arranging the first tubular member in contact with the second tubular member to define a contact area therebetween and joining the first and second tubular members at the contact area by irradiating them to define a fusion area having an intensity gradient.

    摘要： A tissue cutting device is disclosed, which is structured and arranged to be inserted through the vascular system into a body vessel adjacent to the heart and/or into the heart, and to be subsequently subjected to a change of shape in order to penetrate into the heart tissue. The tissue cutting device may thus be used for treating disorders to the heart rhythm regulation system. A kit of tissue cutting devices provides a plurality of devices for creating a lesion pattern for treating such disorders. The tissue cutting device is of a biodegradable material, such as hydrolytically degradable material or an enzymatically degradable material.
