Abstract: An intravascular catheter for peri-vascular and/or peri-urethral tissue ablation includes multiple needles advanced through supported guide tubes which expand with open ends around a central axis to engage the interior surface of the wall of the renal artery or other vessel of a human body allowing the injection an ablative fluid for ablating tissue, and/or nerve fibers in the outer layer or deep to the outer layer of the vessel, or in prostatic tissue. The system also includes means to limit and/or adjust the depth of penetration of the ablative fluid into and beyond the tissue of the vessel wall. The preferred embodiment of the catheter includes structures which provide radial and lateral support to the guide tubes so that the guide tubes open uniformly and maintain their position against the interior surface of the vessel wall as the sharpened injection needles are advanced to penetrate into the vessel wall.

Abstract: A lead distal tip for a pacemaker includes a lead body including an insulated wire having a diameter of 2 French or less. The small size and flexibility of the lead distal tip and lead body reduce penetration and dislodgement risk for the lead distal tip. The lead distal tip can be delivered using a delivery catheter engaging with features on the lead distal tip to allow for the guidance and securement of the lead distal tip, despite its small and flexible nature. The attachment of the lead distal tip to heart tissue can be achieved by extending a linear member and/or a helical member from an end of the lead distal tip using features provided on the delivery catheter.

Abstract: Systems and methods for determining parameters and/or configurations for implantable pulse generator and/or lead(s) for the cardiac conduction system. The method includes configuring a stimulation vector. The method also includes configuring an AV delay to be less than an intrinsic AV delay, controlling a pulse generator to deliver pacing with a pacing amplitude, determining a sensing signal from artifacts of the pacing, adjusting the pacing amplitude based on the determined sensing signal and a capture signal, and determining the pacing threshold based on the adjusted pacing amplitude. The method further includes configuring the AV delay to a percentage of an intrinsic AV delay, controlling the pulse generator to deliver pacing with the AV delay, determining a sensing signal from artifacts of the pacing, adjusting the AV delay based on the determined sensing signal, and configuring the pulse generator with the adjusted AV delay.

Abstract: There are provided a system, method(s), and apparatus comprising multiple interacting machines and sub-systems for autonomously/automatically, semi-autonomously/semi-automatically and/or manually harvesting items such as mushrooms from a mushroom bed, wherein the yield and quality of the harvest can be improved over standard methods of harvesting. The system may be referred to as a “harvesting and packing system”, having multiple interacting sub-systems, machines or apparatus to transport and position a harvester at different levels of a multi-layered growing bed, operate the harvester to scan and harvest items from the growing beds, and transfer harvested or “picked” items such as mushrooms to a packer having a stem cutter, discard bin(s) and collection bin(s) to enable fully autonomous harvesting and packing.

Abstract: A flexible elongated tube for a catheter system includes a tubing wall. The wall has a plurality of first indentations spaced apart from each other along a longitudinal axis (L) of the tube and a plurality of second indentations spaced apart from each other along the longitudinal axis (L). An axially aligned pair of indentations has a non-impressed section between the axially aligned pair of indentations. The axially aligned pair of indentations and the non-impressed section form a pull wire space.
