20160374754 | DEVICES AND METHODS FOR ABLATION OF TISSUE - This document provides devices and methods for the treatment of heart conditions, hypertension, and other medical disorders. For example, this document provides devices and methods for treating atrial fibrillation by performing thoracic vein ablation procedures, including pulmonary vein myocardium ablation. In some embodiments, the ablation is performed in coordination with the delivery a pharmacological agent that can abate the formation of tissue stenosis or neointimal hyperplasia caused by the ablation. | 2016-12-29 |
20160374755 | OPEN-IRRIGATED ABLATION CATHETER - An open-irrigated catheter system includes a catheter body and a tip assembly, coupled to a distal end of the catheter body. The tip assembly includes an exterior wall that is conductive for delivering radio frequency (RF) energy for an RF ablation procedure, and that defines an interior region. The exterior wall includes a number of proximal irrigation ports and a number of distal irrigation ports. At least one fluid chamber is defined within the interior region and is in fluid communication with at least one of the proximal irrigation ports and the distal irrigation ports. At least one fluid lumen extends from a fluid source, through the catheter body, to the tip assembly, and is in fluid communication with the at least one fluid chamber. | 2016-12-29 |
20160374756 | CATHETER HAVING TWO-PIECE CONNECTOR FOR A SPLIT HANDLE ASSEMBLY - A catheter and method for the treatment of a patient having atrial flutter or other arrhythmia comprises an elongated catheter body having an outer wall, proximal and distal ends, and at least one lumen extending therethrough. Further it has a distal tip section comprising a flexible tubing having a proximal end and a distal end and a plurality of lumens extending therethrough. The proximal end of the tip section is fixedly attached to the distal end of the catheter body. The tip section further comprises a nitinol tube having slots formed therein which causes the distal tip section to deflect using the same puller-wire action used to cause the deflectable catheter to deflect at a point proximal to the distal tip section. | 2016-12-29 |
20160374757 | TREATMENT DEVICE AND TREATMENT SYSTEM - A treatment device includes: a linear member which is deformable between a substantially straight state and a tissue catching state and which is configured to catch a treatment target in a state of being deformed in the tissue catching state; and first and second energy emitting portions provided in the linear member to catch the treatment target in cooperation with each other. The second energy emitting portion is apart from the first energy emitting portion, and is configured to emit energy to the treatment target from between the first energy emitting portion and to treat the treatment target. | 2016-12-29 |
