A multi-electrode impedance planimetry measuring system comprising a pair of stimulating electrodes and sensing electrodes is located on the catheter within the balloon for monitoring the diameter of the balloon when the balloon is inflated with a liquid saline solution from a reservoir through a flowmeter under the control of a microprocessor. The microprocessor computes the minimum diameter value from signals read from the sensing electrodes each time the cumulative volume of the liquid saline solution in the balloon increases by a predefined unit volume. The microprocessor computes a curve of a plot of the minimum diameter values against the corresponding cumulative volume values and determines the slope at each computed minimum diameter value. Rupture of the muscle fibres of the sphincter is determined at the point of inflection of the curve.

    Abstract: A growth stent and methods for making and using the same. The growth stent may be delivered to treat early stage congenital lesions, while expanding to adult vessel diameters. In selected embodiments, the growth stent can comprise a frame and may have a covering on some portion to prevent blood flow through a wall of the frame. The growth stent advantageously can maintain radial strength across an entire range of diameters necessary to treat a narrowed lesion from birth and childhood through adulthood as the vessels grow over the lifetime of a patient.

  • Patent number: 10646699
    Abstract: A non-compliant fiber-reinforced medical balloon comprises a first fiber layer and a second fiber layer embedded in a continuous matrix of thermally-weldable polymer material defining a barrel wall, cone walls and neck walls. The fibers of the first fiber layer run substantially parallel to one another and substantially parallel to the longitudinal axis. The fibers of the first fiber layer have a pattern of different lengths and are divisible into a first group and a second group based on length.

  • Patent number: 10617293
    Abstract: The foregoing application describes a system and method of performing a minimally invasive surgical operation. More specifically, the invention involves the use of disposable cannula and slender dilators of variable lengths, which incorporate a source of illumination to carry light to a surgical site and video capabilities for capturing and displaying images from a CMOS or CCD camera device. According to one embodiment, fiber optics run semi-circumferentially or along walls of the cannula/dilator and terminate at about a centimeter from the distal end of the cannula/dilator, thereby preventing illumination from “bottoming out” at the floor of the incision. According to one alternate embodiment, the light fibers may be fashioned in an annulus around one or more camera chips to provide illumination and video of the surgical site.

  • Patent number: 10603020
    Abstract: A medical device for reducing the volume of a left atrial appendage (LAA) may include an elongate shaft having a distal portion, and a volume-reducing means expandable from a collapsed to an expanded state, the volume-reducing means being releasably attached to the distal portion. The volume-reducing means may include an actuatable frame and an impermeable covering disposed over the frame. The volume-reducing means may be sized to fit within the LAA in the expanded state while maintaining an open fluid flow path from a distal region through the ostium of the LAA. A medical device may include a second volume-reducing means to be placed within and substantially occlude a distalmost region of the LAA. A method may include inserting a volume-reducing means into the LAA, expanding the volume-reducing means, and positioning the volume-reducing means such that an open fluid flow path is maintained through an entire cycle of the heart.

  • Patent number: 10568635
    Abstract: A surgical apparatus for application of surgical clips to body tissue is provided. The surgical apparatus includes a housing, a drive assembly, a trigger, and a shaft assembly. The trigger is operatively connected with the drive assembly. The drive assembly is at least partially positioned within the housing. The shaft assembly extends distally from the housing and has a first tubular member pivotally connected with a second tubular member located distally from the first tubular member. An articulation mechanism is operatively connected between the first and second tubular members, and includes a gear rack, at least one gear, and a gear segment, respectfully connected with each other to pivot the second tubular member about the pivot axis. The gear rack and at least one gear are located within the first tubular member. The gear segment extends proximally from the second tubular member.

  • Patent number: 10569009
    Abstract: Methods and systems for automated control of the inflation of an inflatable retention member, e.g. a balloon, in a catheter are disclosed. One catheter is preferably a rectal or anal catheter, and the inflation is controlled by a controller. A plurality of predetermined inflation levels are provided, and for each of level, a pumping time threshold and a pressure level threshold are defined. The pressure in the balloon is continuously measured during the inflation. An inflation level is selected form said plurality of inflation levels, and an electric pump is used to inflate the inflatable retention member. Operation of the electric pump is continued until one of the pumping time threshold and pressure level threshold of the selected inflation level has been reached.

  • Patent number: RE48597
    Abstract: Improved methods and devices for performing an endoscopic surgery are provided. Systems are taught for operatively treating gastrointestinal disorders endoscopically in a stable, yet dynamic operative environment, and in a minimally-invasive manner. Such systems include, for example, an endoscopic surgical suite. The surgical suite can have a reversibly-expandable retractor that expands to provide a stable, operative environment within a subject. The expansion can be asymmetric around a stabilizer subsystem to maximize space for a tool and an endoscope to each be maneuvered independently to visualize a target tissue and treat the target tissue from outside the patient in a minimally invasive manner.
