20100319848METHOD FOR CONNECTING A CATHETER BALLOON WITH A CATHETER SHAFT OF A BALLOON CATHETER - A method for connecting a catheter balloon with a catheter shaft of a balloon catheter that improves the welding quality of a weld between the catheter balloon and the catheter shaft of the balloon catheter. Preferably, a welding energy absorbing device is arranged, preferably in the form of a coloured tubing, in the area of a fixation site after attaching a pre-fixation and then to irradiate this welding energy absorbing device with the radiation energy to carry out the welding. After the welding the pre-fixation and the welding energy absorbing device are removed.12-23-2010

20080294088Biodegradable Tissue Cutting Device, A Kit And A Method For Treatment Of Disorders In The Heart Rhythm Regulation System - 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.11-27-2008
20090209988PATIENT CONFIGURED DEVICE, A KIT AND A METHOD FOR TREATMENT OF DISORDERS IN THE HEART RHYTHM REGULATION SYSTEM - A patient-configured 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 patient configured tissue cutting device may thus advantageously be used for treating disorders to the heart rhythm regulation system of a specific patient. A kit of devices provides a plurality of devices for creating a lesion pattern for treating such disorders, a device, system, and method for determining the shape of said vessel, are also disclosed.08-20-2009
20100016877Controllable Device, A Kit And A Method For Treatment Of Disorders In The Heart Rhythm Regulation System - 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 device comprises at least one connection element that is arranged such that a connection formed from said connection element between a first and second part of said tissue cutting device is configured to break when said connection element is subjected to a specific external influence. The tissue cutting device may thus be used for controllably 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.01-21-2010
20100305603Shape-Changing Medical Device, Kit, Method Of Production, And Method Of Use - The present disclosure relates to treatment of disorders in the heart rhythm regulation system and, more particularly, to a medical device for tissue cutting and/or migrating wherein the cutting and/or migrating is at least partly actuated by the swelling of a swellable material. The disclosure furthermore relates to a method of producing such a medical device, a kit of such medical devices, and a method for treating such disorders.12-02-2010
