    摘要： Devices and methods for facilitating transvascular, minimally invasive and other “less invasive” surgical procedures generally include a sheath with an expandable balloon at the distal end, an inflation lumen for expanding the balloon, and a device passage lumen for allowing passage of one or more surgical instruments. The sheath is configured to house at least one visualization device such that an optical element of the device is positioned to view the surgical site. In some embodiments, instruments may be passed through the sheath, with the distal balloon partially or fully circumscribing or encircling the instruments. Any suitable instrument(s) may be passed through sheaths of the invention, such as a surgical clip applier for repairing a heart valve, an ablation member for treating atrial fibrillation, one or more pacemaker leads, a coronary sinus access device or the like.

    摘要： A tissue removal system comprises a rotatable burr element located within a distal housing and a burr opening. The burr opening is located about a distal surface and side surface of the distal housing. The distal housing is configured to bend or pivot with respect to a proximal housing. The proximal housing comprises an auger hole configured to draw fluid and particulate matter for transport proximally along the length of the tissue removal system. A linkage assembly attaches a drive shaft of the tissue removal assembly to the rotatable burr element to permit rotation of the rotatable burr element when the distal housing is bent or pivoted.

    摘要： The devices and methods generally relate to treatment of occluded body lumens. In particular, the present devices and methods relate to removal of the occluding material from the blood vessels as well as other body lumens. The devices may include a catheter and a cutter assembly, where the cutter assembly has a distal cutter and a proximal cutter. The devices may also include a drive mechanism, a torque shaft, a deflecting mechanism and a torque control mechanism. The torque control mechanism may sweep the cutter assembly when the cutter assembly is deflected.
