  • Patent number: 10314704
    Abstract: Described, in certain aspects of the invention, are apparatuses and methods for deploying artificial devices within the vascular system. One apparatus includes a delivery device having a lumen and a deployment member slidably received within the lumen. This apparatus further includes an artificial device having an anchoring element releasably engaged with the deployment member. Such an apparatus can be percutaneously delivered to a site within a vascular vessel, and thereafter manipulated so that the anchoring element attaches to the vessel wall. The delivery device and deployment member can then be withdrawn from the vessel, whereby the deployment member disengages from the anchoring element, leaving the artificial device implanted in the vessel.

  • Patent number: 10300286
    Abstract: A tool has an outer assembly, which includes a deployment tube, extending around, and moveable with respect to an inner assembly of the tool; the inner assembly includes a single pull wire and a distal member configured to engage an end of an implantable medical device. The deployment tube includes an articulating segment located just proximal to an enlarged distal-most portion, which contains the device and the distal member. Relatively soft and stiff sections of a composite sidewall define the articulating segment and extend alongside one another, such that, when the pull wire is actuated, the composite sidewall causes bending of the segment in two directions. A handle assembly of the tool includes a control member for the pull wire, and may further include a flushing subassembly that has a connector port located at an end of the handle assembly that is opposite a proximal port of the handle.

    Abstract: Stent delivery systems and associated methods for delivering stents are disclosed herein. In several embodiments, a handle assembly for delivering a stent from a tubular enclosure can include a first lead screw having a first lead thread of a first pitch and first handedness, a second lead screw having a second lead thread of a second pitch and second handedness different from the first handedness, and a housing defining threads of the first and second pitches. The first lead screw can be in mechanical communication with the tubular enclosure, and the second lead screw can be in mechanical communication with the stent. Upon rotation of a portion of the housing, the housing threads can engage the lead screws so as to induce simultaneous translations of the lead screws in opposite directions. The simultaneous translations are configured to deploy the stent from the tubular enclosure.

  • Patent number: 10258320
    Abstract: Systems and methods for soft tissue to bone repairs, without knot tying. The soft tissue repair systems include self-cinching constructs with splices, loops and inserts that are pre-loaded onto knotless anchors to position the self-locking, adjustable construct at the repair site. The splice incorporates an insert in the form of a flexible strand with at least one barb, or simply in the form of a cut length of suture or braid that is inserted into the center of the cinching loop to create a thicker portion. When the cinching loop is tightened, the insert prevents loosening of the loop, locking in the cinching loop and preventing movement of the loop.

  • Patent number: 10245100
    Abstract: A connection mechanism and manufacturing method for a surgical instrument includes an inner shaft member that extends at least partially through an elongated shaft member of the instrument and defines proximal and distal ends and is selectively movable in a longitudinal direction with respect to the elongated shaft member and includes at least one aperture that extends partially along the longitudinal direction and disposed distally from the proximal end. The inner shaft member enables a drive collar member to slide on the inner shaft member and reciprocate along the longitudinal direction. A drive collar stop member slides on the inner shaft member and moves along the longitudinal direction. The drive collar stop member then moves in a direction relative to the longitudinal axis to engage the aperture and limit further longitudinal motion of the drive collar member. An inner shaft stop member limits movement of the inner shaft.

  • Patent number: 10195028
    Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve. In one embodiment, for instance, a support member is positioned to at least partially surround the native chordae tendineae and/or leaflets of a valve. The support member can comprise a flexible, distensible material to reduce abrasion and other mechanical damage to surrounding structures. A locking member may be used to couple both ends of the support member, forming a support ring. The support member may have two magnetic end portions which can be magnetically coupled to form a support ring. An expandable prosthetic heart valve can be delivered into the native heart valve and expanded within the support band, thereby causing one or more of the native chordae tendineae and/or leaflets of the native heart valve to be frictionally secured between the support ring and the expanded prosthetic heart valve.
