Abstract: A balloon for renal nerve modulation is disclosed. The balloon may include a polymer material forming a balloon wall having an outer surface and flexible circuits comprising a base selectively adhered to the exterior surface of the balloon wall. Adhesive is selectively applied to the outer surface of the balloon, to the flexible circuit or to both such that the adhesive is selectively deposited on the at least a portion of the at least two pads or on the at least a portion of the at least two pads and to a portion of the distal spline. The portion of the at least two pads or the portion of the at least two pads and a portion of the distal spline are adhered to the outer surface of the balloon and a remainder of the flexible circuit moves freely with respect to the outer surface of the balloon.

Abstract: An introducer set for a microwave ablation probe is disclosed. The introducer set includes a cannula that is at least partially transparent to microwave energy, and a stylet sized to be received by the lumen of the cannula. Other examples provide a microwave ablation system including a microwave ablation probe having a radiating portion and a cannula that is at least partially transparent to microwave energy. The radiating portion of the probe aligns with the transparent portion of the cannula when the probe is inserted into the cannula lumen. The technology provides a method including introducing a microwave ablation probe into the lumen of a cannula having a cannula body that is at least partially transparent to microwave energy, aligning the transparent portion of the cannula with the radiating portion of the probe, and causing microwave energy to be emitted from the radiating portion of the probe.

Abstract: An occlusive implant includes an expandable framework that is configured to shift between a collapsed configuration and an expanded configuration. An occlusive member is disposed along at least a portion of the expandable framework. At least part of the occlusive implant is configured to repel fibrinogen. In some cases, the occlusive implant may be configured for placement within a left atrial appendage (LAA) of a patient's heart.

Abstract: Biological cell destruction is achieved through a combination of injection of a substance and application of an electrical field. The substance, such as a cationic polymer, is selected for its electrical characteristics which can add to the transmembrane electric field of a cell when the electrical field is applied. In some examples, electrical field application is performed to encourage spatial concentration of the injected substance favorable to increased transmembrane field strength. The biological cell or cells are destroyed primarily through irreversible electroporation.

Abstract: A variable-length microwave ablation probe is provided. The probe is configured to have a range of resonant frequencies. The probe includes a microwave antenna, an outer conductor, and a cap. The probe further includes a radiation window that is at least partially transparent to microwave energy. The distal boundary of the outer conductor or the proximal boundary of the cap varies in distance from the probe distal end. The probe can have a choke length, an arm length, a radiating portion length, and a cap length. The lengths can each affect the resonant frequency of the antenna. Some examples provide a variable choke length, a variable arm length, a variable radiating portion length, and/or a variable cap length.

Abstract: A system and method for denervation where a catheter includes a radially expandable member, the radially expandable member including an exterior surface, a plurality of electrodes on the exterior surface configured for delivery of energy during a denervation procedure in a vessel, and a chemical agent coating on the exterior surface, wherein the chemical agent inhibits or prevents nerve regeneration. The radially expandable member is configured to have a first unexpanded configuration and a second expanded configuration, and is configured to bring the exterior surface in contact with a wall of a vessel when it is in the expanded configuration.

Abstract: A deflective medical device including a catheter shaft having a distal end, and an ablation electrode disposed at the distal end of the catheter shaft. A deflection body is provided within the catheter shaft, and the deflection body includes a longitudinally extending spine. Multiple slots are formed in the deflection body, and the slots define a group of ribs. A flex member is disposed distal to the deflection body, and an intermediate region is defined between the deflection body and the flex member. A deflection mechanism is coupled to the intermediate region, which includes a retaining member, a collar, and a pull wire coupled to the collar.
