  • Patent number: 10391286
    Abstract: [Subjects] To provide a biliary tract drainage tube in which both an external drainage tube and an internal drainage tube can be installed in a single endoscopic procedure. [Method to Solve] A biliary tract drainage tube used to drain a biliary tract is provided with long external drainage tube 2 and internal drainage tube 3 that is provided on the tip of the external drainage tube so as to be separable from the external drainage tube. Both external drainage tube 2 and internal drainage tube 3 are placed in biliary tract Cd. Since internal drainage tube 3 can be left behind in the biliary tract by removing external drainage tube 2, another endoscopic procedure is not required when switching from external drainage tube 2 to internal drainage tube 3, and the burden placed on the patient can be lessened.

  • Patent number: 10327894
    Abstract: In some embodiments, a method for delivery and deployment of a prosthetic mitral valve into a heart includes inserting an introducer sheath having a prosthetic mitral valve disposed therein in a collapsed configuration into the left atrium of a patient's heart, through a gap between the native mitral valve leaflets, the left ventricle and apex of the heart. An epicardial pad device coupled to the prosthetic valve via a tether is moved distally out of the sheath. The introducer sheath is withdrawn into the left atrium of the heart. An inner delivery sheath is extended distally from within the introducer sheath and disposed within the left atrium. The prosthetic mitral valve is moved distally out of the inner delivery sheath and assumes a biased expanded configuration. The valve is positioned within the mitral annulus of the heart, and secured in place via the tether and epicardial pad device.

    Abstract: Apparatus and methods for facilitating deployment of an implantable medical device including a stent graft. A restraining device, such as cord or suture, holds at least the proximal end of the stent in a radially inwardly compressed configuration during delivery to a desired location within the lumen of a patient's vessel. Withdrawal of one or more trigger wires facilitates the release and removal of the restraining cord from the proximal end of the stent so as to allow the stent to become fully deployed within vessel.

  • Patent number: 9592120
    Abstract: A prosthesis for implantation at a native semilunar valve includes a prosthetic distal valve, which includes a pliant material configured to collapse inwardly towards a longitudinal axis of the prosthesis during diastole, and to open outwardly during systole, and a distal fixation member configured to be positioned in a downstream artery of the subject. The apparatus also includes a proximal fixation member coupled to the distal fixation member, and configured to be positioned at least partially on a ventricular side of the native semilunar valve. The proximal fixation member is shaped so as to define a lattice that is shaped so as to define an intermediary portion that is coupled to the pliant material of the valve and diverges outwardly from the longitudinal axis, and a distal portion that is distal to the intermediary portion and diverges outwardly from the intermediary portion of the lattice. Other embodiments are also described.

  • Patent number: 9579197
    Abstract: A valve retainer is connected to an elongate delivery member. The valve retainer is configured to releasably secure a prosthesis (e.g., a heart valve prosthesis) to the delivery member during delivery to a target site in a body (e.g., a native valve annulus). The valve retainer includes a rotational identifier that identifies the rotational orientation of the valve retainer when the valve retainer is positioned proximate to the target site. A heart valve prosthesis can include a commissural post that has a predetermined rotational position relative to the rotational identifier, such that the heart valve prosthesis can be rotationally aligned with the native commissures of the native valve by rotating the delivery member and the valve retainer until the commissural post is aligned with a native valve commissure and the rotational identifier is visible.

  • Patent number: 9579103
    Abstract: Some embodiments are directed to methods and systems for percutaneously treating dissections in a patient's vasculature, such as, without limitation, the aorta. The method can include deploying a catheter containing a collapsed anchoring element, frame, and cover through a first vessel to an entry point of the dissection. The anchoring element can be secured to the second branch vessel. The frame can be expanded in the first branch vessel. The cover can be unfolded over at least a portion of the entry point. The cover then reduces blood flow into the entry point.

  • Patent number: 9498361
    Abstract: An endoluminal prosthesis includes an expandable stent graft that includes a cannula extending through a lumen of the stent graft. A suture is threaded along the perimeter of the graft through openings therein, with an inner end of the suture mounted to the cannula. The cannula is rotatable relative to the graft to wind or unwind the suture around the cannula and cause the graft to become compressed when wound or allow the graft to expand when unwound. The cannula includes an attachment member for retaining an inner end of the suture, and the attachment member can release the inner end of the suture when adjustment of the graft diameter is no longer desired.

  • Patent number: 9445929
    Abstract: A delivery device can provide sequential delivery of a plurality of intraluminal devices or tacks held in a compressed state on the delivery device. Delivery platforms on the delivery device can hold a tack in a compressed position and have a unique shape, such as a non-constant outer diameter, an hourglass shape, a tapered proximal half, ridges, dimples, etc. This unique shape can be positioned between annular pusher bands that may also be radiopaque markers. In some embodiments, the unique shape is provided by a sleeve of flexible material with the unique shape surrounding a harder inner shaft. Further, the annular pusher bands can be made of wire or sections of material to increase flexibility while remaining radiopacity. A tack deployment method can include alignment of radiopaque markers on the outer sheath and the tack to be deployed prior to deployment.

  • Patent number: 9433429
    Abstract: A self-expandable mechanical clot retrieval device is designed variously to dislodge, engage and retract blood clot from extremely small and tortuous vasculature. The retrieval device comprises an elongate member and a plurality of ring elements. The ring elements may comprise a plurality of struts and crowns interconnected by a tether formed at a distal end of the elongate member or may be a separate component attached thereto. At least one tether may connect each ring element to the elongate member to restrain the ring element in a collapsed configuration during delivery of the retrieval device through an intravascular microcatheter. The tether connecting the ring element to the elongate member disengages when the retrieval device is positioned at the occluded site and the microcatheter is retracted to allow the self-expandable ring elements to reach an expanded configuration.
