Abstract: An example system for use in ablating target tissue includes memory configured to store anatomical and/or physiological information of a patient and processing circuitry communicatively coupled to the memory. The processing circuitry is configured to, based on the anatomical information and/or the physiological information, determine ablation parameters, the ablation parameters including a suggested positioning of at least energy delivery element of at least one catheter and/or an amount of energy to be delivered via the at least one energy delivery element to the target tissue during ablation. The processing circuitry is configured to output, for display, a representation of at least one of a suggested positioning of the at least one energy delivery element during the ablation, a representation of the target tissue, or a representation of the predicted tissue volume that will be ablated after delivery of ablation energy.

Abstract: A method of percutaneously delivering a multi-layered stent assembly to a desired implantation location of a patient including the steps of radially compressing a multi-layered stent assembly to a compressed size for implantation in a patient, the multi-layered stent assembly including a first stent, a second stent coaxially positioned within at least a portion of a length of the first stent, and a valve, wherein the first stent comprises at least one different material property than the second stent. The method further includes delivering the multi-layered stent assembly to the desired implantation location of the patient using a delivery system and substantially simultaneously expanding the first stent and the second stent of the multi-layered stent assembly at the desired implantation location to a radially expanded size that is larger than the compressed size.

Abstract: A method and a pulsed electric field (PEF) ablation instrument are provided. According to one aspect, a method in a PFA generator includes receiving electrical responses for each of at least one non-therapeutic waveform. The process also includes determining an electric field distribution based at least in part on the received electrical responses. The process further includes selecting a non-therapeutic waveform that produces an electric field distribution that satisfies criteria.

Abstract: A method and system for directed pulsed electric field (PEF) ablation are disclosed. In one aspect, an irreversible electroporation (IRE) system includes processing circuitry configured to select a first set of electrodes positioned to produce a first electric field in a first direction in a region of tissue of a patient, and select a second set of electrodes positioned to produce a second electric field in a second direction in the region of tissue. The processing circuitry is configured to transmit a first IRE pulse to the first set of electrodes to cause emission of the first electric field and transmit a second IRE pulse to the second set of electrodes to cause emission of the second electric field. The first IRE pulse and the second IRE pulse are transmitted by the processing circuitry to control an electric field gradient along a path within the region of tissue.
