  • Patent number: 10499893
    Abstract: An apparatus for sealing a puncture through a vessel wall including a positioning assembly, a sheath releasably engaged with the positioning assembly, and a support member axially advanceable through the sheath. The positioning assembly includes a positioning element positioned at a distal portion of the positioning assembly and a sealant disposed at a distal portion of the positioning assembly. The sheath guides the sealant and positioning assembly to the puncture in the vessel wall.

  • Publication number: 20190273872
    Abstract: System and method for enabling capturing of multiple images from a display device in which multiple image capturing devices disposed, at least partially, in the display device are controllably oriented to capture opposing offset views of a subject for combining (e.g., via optical tiling of captured image data) into a composite view.

  • Publication number: 20190175870
    Abstract: A neuromodulation catheter includes an elongate shaft and a neuromodulation element. The shaft includes two or more first cut shapes and two or more second cut shapes along a helical path extending around a longitudinal axis of the shaft. The first cut shapes are configured to at least partially resist deformation in response to longitudinal compression and tension on the shaft and torsion on the shaft in a first circumferential direction. The second cut shapes are configured to at least partially resist deformation in response to longitudinal compression on the shaft and torsion on the shaft in both first and second opposite circumferential directions.

  • Patent number: 10076382
    Abstract: Catheter apparatuses, systems, and methods for achieving renal neuromodulation by intravascular access are disclosed herein. One aspect of the present technology, for example, is directed to a treatment device having a multi-electrode array configured to be delivered to a renal blood vessel. The array is selectively transformable between a delivery or low-profile state (e.g., a generally straight shape) and a deployed state (e.g., a radially expanded, generally helical shape). The multi-electrode array is sized and shaped so that the electrodes or energy delivery elements contact an interior wall of the renal blood vessel when the array is in the deployed (e.g., helical) state. The electrodes or energy delivery elements are configured for direct and/or indirect application of thermal and/or electrical energy to heat or otherwise electrically modulate neural fibers that contribute to renal function or of vascular structures that feed or perfuse the neural fibers.

  • Publication number: 20150305808
    Abstract: The present disclosure relates to devices, systems and methods providing evaluation and feedback to an operator of a device providing neuromodulation treatment, such as modulation of renal nerves of a human patient. In one embodiment, for example, a system monitors parameters or values generated before treatment. Feedback provided to an operator is based on the monitored values and relates to an assessment of various electrical properties associated with an electrode carried by a catheter. The electrode measures an electrical property of biological material making contact with the electrode while deploying the electrode, the electrical property being dependent on a ratio of a wall-interface area to a fluid-interface area.

  • Patent number: 9138578
    Abstract: Endovascular catheters and control wires for operating the catheters and associated systems, apparatuses, and methods are disclosed include a catheter apparatus having an elongated shaft, a therapeutic assembly at a distal portion of the shaft, and a handle at a proximal portion of the shaft. An actuator is located at the handle and operably coupled to the therapeutic assembly via a tuned control member extending through the shaft. The tuned control member includes a control wire and a tuning component attached to one another within the shaft. The tuned control member is configured to achieve a desired tuned force-displacement response by modifying the stress-strain response that a non-tuned control wire would ordinarily provide without the intervening tuning component.
