  • Patent number: 12016605
    Abstract: An inflatable bone tamp for performing a minimally invasive surgical procedure includes an outer shaft defining an internal lumen, an inflatable structure coupled to the outer shaft, and an inner shaft movably disposed within the internal lumen and coupled to a distal end region of the inflatable structure. The internal lumen is sized to receive the inflatable structure, such that by moving the inner shaft relative to the outer shaft, the inflatable structure can be retracted into the internal lumen (and likewise can be extended from within the internal lumen for deployment in bone). This retraction capability can beneficially protect the inflatable structure during positioning/removal, and can also enhance recovery from radial tears of the inflatable structure.

    Abstract: A flexible, polymer sleeve is provided that is everted into a body passageway in such a manner as to exert minimal rubbing friction on the internal walls of such passageway. The sleeve is housed within a tube assembly comprising a posterior tube that telescopingly slides into an insertion tube. The sleeve everts over the insertion tube, upon forward pressure applied thereon, as it extends forward into a body passageway, and consequently, causes the posterior tube to retract into the insertion tube. Multiple tubes can be telescoped to support the polymer sleeve and to keep a passageway open for the expelling of urine or body fluids, the insertion of tools, sanitation/antibacterial substances, or for the flow of liquids through the sleeve. The insertion tube can be locked in reference to the sleeve to prevent unintended removal of catheter assembly. Sleeve and tubing are removed by reversing the insertion and eversion movements.

  • Patent number: 11717405
    Abstract: A method for replacing a stenotic native aortic valve of a patient can include inserting a delivery apparatus into a femoral artery of the patient, the delivery apparatus having a first shaft extending from the handle, a second shaft disposed around the first shaft, a third shaft extending through the second shaft, and a valve cover coupled to the first shaft. The valve cover can be in a first state housing an entirety of a prosthetic heart valve and retaining the prosthetic heart valve in a radially compressed state during the act of inserting. The method can further include advancing the delivery apparatus through the aorta of the patient to position the valve cover and the prosthetic heart valve within the native aortic valve, and moving the valve cover longitudinally from the first state to a second state in which the entirety of the prosthetic heart valve is uncovered.
