Abstract: Methods, devices and systems for treating patent foramen ovale (PFO) involve advancing a catheter device to a position in a heart for treating a PFO, bringing tissues adjacent the PFO at least partially together, and applying energy to the tissues to substantially close the PFO acutely. Catheter devices generally include an elongate catheter body, at least one tissue apposition member at or near the distal end for bringing the tissues together, and at least one energy transmission member at or near the distal end for applying energy to the tissues. In some embodiments, the tissue apposition member(s) also act as the energy transmission member(s). Applied energy may be monopolar or bipolar radiofrequency energy or any other suitable energy, such as laser, microwave, ultrasound, resistive heating or the like.

Abstract: RF power is applied to a circular RF electrode cutting a side opening in a graft material of a main stent-graft in situ. As the side opening is formed by the applied RF power and the associated plasma discharge, the side opening is formed with a minimal application of force to the graft material. Further, the side opening is circular and has a fused edge.

Abstract: An ablation catheter comprises a catheter body extending longitudinally between a proximal end and a distal end along a longitudinal axis; and an ablation element assembly comprising ablation elements connected to the catheter body, each ablation element to be energized to produce an ablation zone. The ablation elements are distributed in a staggered configuration such that the ablation zones of the ablation elements span one or more open arc segments around the longitudinal axis, but the ablation zones of all ablation elements projected longitudinally onto any lateral plane which is perpendicular to the longitudinal axis span a substantially closed loop around the longitudinal axis. Since the ablation zones do not form a closed loop, the risk of renal artery/vein stenosis is reduced or eliminated. Since the ablation zones of all ablation elements projected longitudinally onto any lateral plane span a substantially closed loop, substantially complete renal denervation is achieved.

Abstract: A robot system for endoscopic treatment includes a gripping unit, a manipulator unit, a treatment instrument drive unit, a gripping force detection unit, a control unit. The gripping unit is inserted into a body cavity along with an endoscopic apparatus and grips desired living tissue using gripping members. The manipulator unit includes a multi-joint structure that enables bending and stretching. The treatment instrument drive unit pulls and pays out wires. The gripping force detection unit detects gripping force provided by the gripping members. The control unit instructs the treatment instrument drive unit to pull and pay out the wires for the gripping operation so that the gripping force detected by the gripping force detection unit falls within a predetermined range when the gripping unit in the gripping state moves.

Abstract: Methods and apparatus for treatment of patent foramen ovale (PFO) provide for applying energy to tissues adjacent the PFO with a catheter device to substantially close the PFO acutely. Apparatus generally includes a catheter device having at least one energy transmission member at or near its distal end configured to apply energy to PFO tissues to acutely, substantially close the PFO. Applied energy may be monopolar or bipolar radiofrequency energy or any other suitable energy, such as laser, microwave, ultrasound, resistive heating or the like. Some embodiments of a catheter device further include one or more tissue apposition members near the distal end for helping bring PFO tissues together, such as a PFO covering member, a vacuum applying member and/or the like. PFO closure via energy-based approaches of the invention may help prevent stroke, treat migraine headache, and possibly treat or prevent other medical conditions.

Abstract: A textile fabric has at least one raised surface incorporating multicomponent fibers formed of at least a first polymer and a second polymer disposed in side-by-side relationship. The first polymer and the second polymer exhibit differential thermal elongation, which causes the multicomponent fibers to bend or curl and reversibly recover in response to changes in temperature, thereby adjusting insulation performance of the textile fabric in response to ambient conditions.

Abstract: Disclosed is a shape memory polyamide, produced by adding a polyvalent carboxylic acid and a polyvalent amine when polyamide is polymerized from e-caprolactam or hexamethylenediamine and adipic acid, and having an aromatic component which is introduced by one or more among the polyvalent carboxylic acid and the polyvalent amine and has a total amount ranging from 0.4 mol % to 10 mol % based on the amount of the raw material for polyamide. Also, a method of producing a shape memory polyamide fabric using the shape memory polyamide is provided. The polyamide fabric produced using the shape memory polyamide is a highly functional fabric which does not easily wrinkle and easily recovers its original shape even when wrinkled, and thus may be applied as material for various kinds of clothing.
