摘要： In various embodiments, provided herein are devices, systems and methods using two, three or more pigtails for precisely imaging an aortic valve complex with minimal contrast and/or for advancing an instrument, such as a wire, or device, such as a transcatheter valve, across an aortic valve. In various embodiments, these devices, systems and methods may be used to diagnose and/or treat patients with aortic stenosis, other valvular heart disease or other cardiovascular or non cardiovascular disease, facilitating precise contrast or drug or device delivery, precise pressure measurement and/or precise drainage or sampling. In some embodiments, each of the multiple pigtails of the device may be advanced independently of one another in multiple directions and at multiple lengths of deployment to optimize position.

摘要： A method and system for performing pulmonary vein isolation, mapping, and assessing pulmonary vein occlusion using a single device. The device may generally include an ablation element, such as a cryoballoon, and a sensing component slidably disposed within a lumen of the device and bearing one or more mapping electrodes and one or more pressure sensors. The method may generally include mapping cardiac electrical signals within a heart and/or pulmonary vein, positioning a distal portion of the sensing component within a pulmonary vein, advancing the ablation element until it is in contact with the pulmonary vein ostium, recording blood pressure measurements within the pulmonary vein with the one or more pressure sensors to assess pulmonary vein occlusion, and activating the treatment element when the pulmonary vein is completely occluded. The sensing component may have a straight or hooped configuration, or a configuration therebetween.

摘要： A device, system, and method for providing support to a mapping catheter during mapping or pacing and for adjusting the diameter of a distal loop portion of currently available mapping catheters. A medical device support device includes an elongate body defining a wall and an at least substantially linear proximal portion and a distal portion being transitionable between an at least substantially linear configuration and an expanded configuration, the elongate body defining a lumen extending through the proximal portion and distal portion, the lumen being entirely surrounded by the wall in the proximal portion and being partially surrounded by the wall in the distal portion. For example, the lumen may be sized to receive a mapping catheter therein such that adjustment of the configuration or diameter of the distal portion of the elongate body will likewise modify the configuration or diameter of the distal portion of the mapping catheter.

摘要： A biopsy device is proposed comprising a shaft and a tubular member. The shaft is movably, i.e. rotatably as well as shiftably accommodated within the tubular member and comprises a spiral at a distal end portion of the shaft, wherein the spiral is formed by a twisted sheet. Such a spiral may be considered as a laterally open thread having no solid core.

摘要： A volume mapping instrument (20), deployable within a partially or a completely enclosed anatomical volume, employs one or more medical tools (40) with each medical tool (40) being transitional between a deployable structural configuration to orderly position each medical tool (40) within the anatomical volume and a mapping structural configuration to anchor the medical tool (40) against the boundary of the anatomical volume. The volume mapping instrument (20) further employs an optical shape sensor (30) to generate one or more encoded optical signals indicative of a shape of the boundary of the anatomical volume in response to each medical tool (40) being transitioned from the deployable structural configuration to the mapping structural configuration within the anatomical volume. Based on the encoded optical signal(s), a volume mapping module (51) is utilized to map a portion or an entirety of the boundary of the anatomical volume.
