  • Publication number: 20210128208
    Abstract: A bone stabilizing plate includes two plate portions, each affixable to bones of a patient, the plate portions telescoping together with mating rails and grooves. A limiter associated with one of the plate portions sliding engages one a catch associated with the other of the plate portions, when the plate portions are telescoped together, and resists stops telescoping when the plate portions are telescoped a predetermined distance apart. Once the limiter and catch are engaged, the plate portions enable imposition of a minimum compressive force between bones connected to the plates. The limiter is resiliently positioned to deflect into a relief formed in its respective plate portion. A groove positioned proximate the catch enables free telescoping motion limited by the engagement of the catch and limiter, whereby the minimum compressive force between bones is maintained, and Wolfe's Law may apply.

    Abstract: Described here are devices and methods for forming a fistula between two vessels. In some instances, the fistula may be formed between a proximal ulnar artery and a deep ulnar vein. The fistula may be formed using an electrode, and may be formed with a first catheter placed in a first blood vessel and a second catheter placed in a second blood vessel. In some instances, access to the proximal ulnar artery may be achieved through a brachial artery, and access to the deep ulnar vein may be achieved through a brachial vein.

    Abstract: Systems, devices, and methods for transvascular ablation of target tissue are disclosed herein. The devices and methods may, in some examples, be used for splanchnic nerve ablation to increase splanchnic venous blood capacitance to treat at least one of heart failure and hypertension. For example, the devices disclosed herein may be advanced endovascularly to a target vessel in the region of a thoracic splanchnic nerve (TSN), such as a greater splanchnic nerve (GSN) or a TSN nerve root. Also disclosed are method of treating heart failure, such as HFpEF, by endovascularly ablating a thoracic splanchnic nerve to increase venous capacitance and reduce pulmonary blood pressure.

  • Publication number: 20210128230
    Abstract: A catheter shaft includes an elongate body extending from a proximal end to a distal end and including a proximal portion and a deflectable distal portion. The distal portion is selectively deflectable in at least one direction by actuation of a shaft actuator assembly. The elongate body defines at least one lumen extending from the proximal end to the distal end. The catheter shaft also includes a loop actuation wire extending through the at least one lumen and being operable to selectively adjust a diameter of an electrode loop assembly coupled at the distal end of the elongate body. The catheter shaft further includes a first coil wound around the loop actuation wire along the proximal portion of the elongate body and a second coil wound around the loop actuation wire along the distal portion of the elongate body. The second coil has a more flexible construction than the first coil.

  • Publication number: 20210128232
    Abstract: A mapping catheter comprises a flexible shaft having a proximal end and an opposite distal end, and an expandable mapping element attached to the distal end of the shaft. The expandable mapping element is configured to self-expand from a collapsed configuration to an expanded configuration. The expanded configuration is defined by a proximal portion extending from the distal end of the shaft and forming a proximally-facing concave recess, an intermediate portion extending distally from the proximal portion and defining a maximum diameter of the mapping element when in the expanded configuration, and a distal portion having a conical shape with a distal portion diameter that decreases in a direction distally of the intermediate portion. The mapping element further includes a plurality of electrodes located in one or both of the intermediate portion or the distal portion.

  • Publication number: 20210128236
    Abstract: An automated laser-surgery system for performing a closed-loop surgical procedure is disclosed. The procedure includes forming a post-procedural goal based on a three-dimensional (3D) image of a surgical site, planning a path for a surgical laser signal based on the post-procedural goal, performing a procedural pass by steering the surgical laser signal along the path, measuring the surface of the surgical site after the procedural pass, updating a model based on the measured effect at the surgical site, and evaluating the success of the procedural pass based on the surface measurement and the post-procedural goal. If necessary, a new path is planned based on the post-procedural goal and the surface measurement a new pass based on that path is performed, and the surface is again measured to evaluate the success of the new pass. These operations are repeated as a closed-loop sequence as many times as necessary to achieve success.

  • Publication number: 20210128238
    Abstract: A co/counter propagating acousto-optic modulator is provided that creates a low-intensity focused ultrasound (FUS) wave on a laser beam in a medium such as water without any auxiliary mediators or special software/hardware. The main optical effect of the FUS is the controllable focusing of the laser beam through modification of the refractive index of the medium in a time-stable and dynamic fashion. The laser beam and the FUS wave are coaxially mixed and propagated through each other. The FUS pressure field highly amplifies the power density, highly amplifies the intensity, sharpens the diameter, and reduces the full width at half maximum (FWHM) of the laser beam. The FUS pressure field keeps the laser beam's lensing power positive, with small fluctuations, as long as the ultrasound wave is coaxially propagated with the laser beam.

  • Publication number: 20210128239
    Abstract: A medical instrument includes two jaw members, at least one of which creates conditions of frustrated total internal reflection at a tissue-contacting surface when tissue is grasped between the two jaw members. The first jaw member may include an optical element having a tissue-contacting surface. The medical instrument also includes a light source that provides a light beam for sealing tissue. The light source is positioned so that the light beam is totally internally reflected from an interface between the tissue-contacting surface and air when tissue is not grasped by the jaw members. When tissue is grasped by the jaw members, at least a portion of the light beam is transmitted through that portion of the tissue-contacting surface that is in contact with the tissue. The light source may be movably coupled to a jaw member to scan the light beam and/or to change the incident angle based on optical properties of the tissue.
