  • Patent number: 10857015
    Abstract: A sheath of a delivery system is retracted by winding in cords coupled to the sheath. More particularly, a helical reel is rotated to wind the cords into a helical cord groove and retract the sheath. Rotation of the helical reel simultaneously causes a cord feed ring to slide ensuring that that the cords are correctly fed into the helical cord groove through cord feedthrough apertures of the cord feed ring. Initially, due to a minimal diameter of the helical cord groove, the cords are retracted slowly and with a high amount of torque, e.g., a high mechanical advantage. After retraction of the sheath has begun, the speed of retraction of the sheath is increased with reduced torque as the cords are wound around the increasing diameter of the helical cord groove.

  • Patent number: 10786351
    Abstract: Apparatus and methods are described herein for use in the transvascular delivery and deployment of a prosthetic mitral valve. In some embodiments, a method includes inverting an outer frame of a prosthetic mitral valve when the valve is in a biased expanded configuration. After inverting the outer frame, the prosthetic mitral valve is inserted into a lumen of a delivery sheath such that the mitral valve is moved to a collapsed configuration. The distal end portion of the delivery sheath is inserted into a left atrium of a heart. The prosthetic mitral valve is moved distally out of the delivery sheath such that the inverted outer frame reverts and the prosthetic mitral valve assumes its biased expanded configuration. In some embodiments, actuation wires are used to assist in the reversion of the outer frame. The prosthetic mitral valve is then positioned within a mitral annulus of the heart.

  • Patent number: 10098771
    Abstract: A sheath is placed over a crimped scaffold to reduce recoil of the crimped polymer scaffold and maintain scaffold-balloon engagement relied on to hold the scaffold to the balloon when the scaffold is being delivered to a target in a body. The sheath has an opening spanning the length of the sheath. The opening spans an arc length of about 90 degrees with respect to the circumference of the scaffold or balloon. The sheath may be removed from the scaffold by pinching the sheath between a thumb and forefinger, or bending or peeling back the sheath from the edges of the opening using fingertips.

  • Patent number: 10064746
    Abstract: The present embodiments provide systems and methods for deploying at least a portion of a stent. In one embodiment, the system comprises a cannula having an outer surface, and at least one coiled member having proximal and distal ends and a plurality of turns disposed therebetween. One of the proximal and distal ends of the coiled member is secured to the outer surface of the cannula, and the other of the proximal and distal ends of the coiled member is unsecured relative to the outer surface of the cannula. A portion of a stent is looped around the unsecured end of the coiled member and disposed within spacing between adjacent turns of the coiled member. Rotation of the cannula subsequently causes the portion of the stent to disengage from the coiled member.

  • Patent number: 9974679
    Abstract: Stent delivery systems and methods for making and using the same are disclosed. An example stent delivery system may include an inner member having a proximal end. A sleeve may be coupled to the inner member adjacent to the proximal end. A deployment sheath may be disposed about the inner member. A gear rack assembly may be coupled to the deployment sheath. A stent may be disposed between the inner member and the deployment sheath. A handle may be coupled to the inner member and to the deployment sheath. The handle may include an actuation member. The actuation member may be coupled to the gear rack assembly so that actuation of the actuation to member shifts the longitudinal position of the gear rack assembly and the deployment sheath. An engagement mechanism may be coupled to the gear rack assembly. The engagement mechanism may be configured to engage the sleeve of the inner member so that proximal retraction of the gear rack assembly results in proximal retraction of the inner shaft.

  • Patent number: 9918823
    Abstract: A reinforcing ring (10) for a fenestration (32) of a stent graft which can be surface treated such as by passivation and/or electropolishing. The reinforcing ring has several turns of a substantially inextensible resilient wire (12) in a circular two dimensional planar shape and terminal ends (14) at each end of the wire. The terminal ends each comprising a loop (14) and a tail (16). The tail is folded back and extends around the circular shape. Each of the tails of the terminal loops can have an enlarged end. The reinforcing ring can be straightened out for surface treatment such as passivation and/or electropolishing with substantially no part of the circular shape, the loops or tails touching each other.

  • Patent number: 9820877
    Abstract: A vascular intervention device delivery system, such as for implanting a self expanding stent, includes a thumbwheel rotatably mounted in a handle. The thumbwheel includes a radially outward thumb surface. A catheter has a proximal end attached to the handle, and a distal carrier segment for mounting a vascular intervention device thereon. A retractable sheath is movable from a first position covering the distal carrier segment to a second position retracted proximally uncovering the distal carrier segment. A pull extends between the thumbwheel and the retractable sheath. A holding mechanism is operably positioned between the handle and the thumbwheel, and includes a wedge pin trapped to move in a wedge shaped cavity between a wedged position that prevents the thumb wheel from rotating, and an unwedged position that permits the thumbwheel to rotate to facilitate deployment of a self-expanding stent.
