Abstract: A leaflet resection catheter apparatus and system for a Transcatheter Aortic Valve Replacement (TAVR) procedure including a catheter configured at a distal end with a guidewire to deploy the catheter within a vessel lumen to a situs of an aortic valve for leaflet resection; an accessory tool configured with a set of grasping elements attached at a catheter's distal end to enable the accessory tool to travel down the vessel lumen to the situs of the aortic valve to exert a pulling action to draw the aortic valve leaflet in a direction towards the catheter's distal end to draw a portion of the aortic valve leaflet into a protective sleeve of the catheter at the catheter's distal end; and one or more fibers of a ring of fibers surrounding the catheter's distal end to resect tissue that includes a portion of the aortic valve leaflet drawn into the protective sleeve.

Abstract: Systems and Apparatuses for valve clip removal that includes a catheter configured with a first lumen, and a second lumen; a cutting sheath configured with a cutting mechanism; wherein the first lumen is used to deploy a first snare that enables securing a first section of a valve clip; wherein the second lumen is used to deploy a second snare that enables securing of a second section of the valve clip; upon securing the first section of the valve clip, the second snare pulls the cutting sheath over part of the second section of the valve clip for the cutting sheath to: capture part of a second section of valve clip and grasp the valve clip in a stable position, and execute a removal action across the part of the second section of valve clip to detach the valve clip from a valve leaflet whilst the valve clip is grasped; and after performing the removal action and liberating the valve clip from the valve leaflet, the cutting sheath and grasped valve clip are removed through the catheter.

Abstract: A method is provided for determining whether a section of a lead has adhered to a blood vessel. The method comprises obtaining data corresponding to the blood vessel with a lead inside and determining motion vectors corresponding to the lead from the data corresponding to the blood vessel. The motion vectors are input into a machine learning algorithm trained to learn the correlation between the motion vectors and whether a section of a lead has adhered to a blood vessel and output an adherence level for segments of the lead.
