  • Patent number: 10952677
    Abstract: Apparatus for rupturing muscle fibres in a lower oesophageal sphincter comprises a balloon catheter. 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.

  • Patent number: 10307248
    Abstract: A medical device includes an expandable conduit, a prosthetic heart valve and a delivery device, including a balloon catheter. The expandable conduit may include one or more inner or outer sleeves supported by a frame or stent. The sleeve(s) may be a bioprosthetic tissue wrapped, molded or sewn about the frame or stent. Coupled to an end of the expandable conduit is the prosthetic heart valve. The conduit and heart valve may be crimped on the balloon catheter for percutaneous deployment. The frame may be constructed of a balloon-expandable material for the conduit portion and a self-expandable material for the prosthetic heart valve portion. The prosthetic heart valve is anchored at the native heart valve and then the conduit to be expanded into place to protect the aorta. The self-expanding prosthetic heart valve avoids the need for balloon mounting. This provides for a smaller diameter and easier delivery.
