  • Patent number: 10327896
    Abstract: An expandable introducer sheath for passage of implant delivery catheters, such as catheters for delivery of prosthetic heart valves. The expandable sheath balances the amounts, shapes and positions of various stiff and elastic structures in the sheath to selectively program the expandability and buckling stiffness of the sheath. The expandable sheath can include, for example, an expandable tubular layer that includes alternating stiff and elastic wall portions of a single radial thickness. The combination of stiff and elastic wall portions allow for torque and push strength to advance the expandable sheath while at the same time accommodating temporary expansion. The expandable sheath can also be reinforced with a tubular layer of braided fibers or a stent structure for additional strength. Other embodiments include selective use of slots or gaps at the distal end of a stiff wall portion to enhance expandability and distribute strain.

  • Patent number: 9987134
    Abstract: Embodiments of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such embodiments can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some embodiments can include a sheath with inner and outer layers, where a folded portion of the inner layer extends through a slit in the outer layer and a portion of the outer layer overlaps the folded portion of the inner layer. Some embodiments include an elastic outer cover positioned outside the outer layer. Embodiments of the present expandable sheath can avoid the need for multiple insertions for the dilation of the vessel, thus offering advantages over prior art introducer sheaths.

  • Patent number: 9925074
    Abstract: Self-expandable, woven intravascular devices for use as stents (both straight and tapered), filters (both temporary and permanent) and occluders for insertion and implantation into a variety of anatomical structures. The devices may be formed from shape memory metals such as nitinol. The devices may also be formed from biodegradable materials. Delivery systems for the devices include two hollow tubes that operate coaxially. A device is secured to the tubes prior to the implantation and delivery of the device by securing one end of the device to the outside of the inner tube and by securing the other end of the device to the outside of the outer tube. The stents may be partially or completely covered by graft materials, but may also be bare. The devices may be formed from a single wire. The devices may be formed by either hand or machine weaving.

  • Patent number: 9925077
    Abstract: The invention relates to a delivery system for delivering a stent (S) into a body vessel of a patient, comprising a flexible catheter tube (3) having a proximal and a distal end for delivering the stent (S) to a predetermined location in the body vessel and a catheter tip (1) having a longitudinal direction, which is disposed at the distal end of the catheter tube (3). The catheter tip (1) has a stent chamber (150) to receive the stent (1). The catheter tip has a first pressure chamber (20, 22). In the catheter tube (3) a first fluid channel (31) extends from the proximal end to the first pressure chamber (20, 22) of the catheter tip (1). The volume of the first pressure chamber (20, 22) can be enlarged by delivering a first fluid from the first fluid channel (31) to the first pressure chamber (20, 22), such that the stent (S) is released from the stent chamber (150) at the predetermined location in the body vessel.

  • Patent number: 9901468
    Abstract: A stent delivery system includes a distal-side tube, a proximal-side tube, a fixing tube, a stent containing tubular member, a stent in the stent containing tubular member, and a pulling wire for moving the stent containing tubular member to the proximal side. The distal-side tube includes a distal-side priming slit provided in a side wall in proximity to a stent proximal end lock section and a proximal-side priming slit provided in a side wall on the proximal side of the distal-side tube. The slits are opened by injecting liquid, with the distal opening or the rear end opening of a guide wire lumen of the distal-side tube closed.

  • Patent number: 9901472
    Abstract: A stent delivery system can include a core wire and a self-expanding member disposed along the core wire. The self-expanding member can be used to facilitate expansion of a stent or other implantable device within the vasculature of a patient. The self-expanding member can include first and second end portions that are each axially slidable along the core wire and be able to expand from a collapsed configuration to an expanded configuration upon axial convergence of the first and second end portions.

  • Patent number: 9889007
    Abstract: A heart valve delivery system includes a low-profile catheter having an outer sheath, the outer sheath having therein a stent and a replacement heart valve. In an unemployed configuration, the stent is located distally to the replacement heart valve. Upon deployment, however, the stent and replacement heart valve are expanded and the replacement heart valve is situated within the stent.

  • Patent number: 9877748
    Abstract: Facet joint replacement implants may be designed for use on multiple adjacent vertebral levels. Each superior implant may have a substantially semispherical concave surface, and each inferior implant may have a cooperating semispherical convex surface that is deformable to enable it to be pressed into the superior implant concave surface to fix the relative orientations of the superior and inferior implants. Thus, the inferior implant may be attached to the same pedicle as the superior implant, but may also be oriented independently of the superior implant and then fixed in position. Similar mounting structures may be used to attach one or more fusion implants to a level adjacent to that of a facet joint replacement implant.

  • Patent number: 9844453
    Abstract: Described herein is a positioning tool having an elongate portion for carrying a medical implant. Also described is a method of positioning a medical implant using an elongate positioning tool. One form of the method includes positioning a medical implant on a distal portion of an elongate positioning tool, inserting the positioning tool with the implant thereon into a body cavity manipulating the positioning tool to position the implant into contact with tissue at an attachment location, attaching the implant to surrounding tissue at the attachment location, separating the implant from the positioning tool, and withdrawing the positioning tool from the body. In a preferred embodiment, the position of the implant is visually confirmed using an endoscope before the implant is attached to surrounding tissue. In one embodiment, the implant is a satiation device and the body cavity is the esophagus and/or stomach.

  • Patent number: 9839514
    Abstract: An assembly for treating a native heart valve can include a prosthetic valve and a delivery apparatus. The prosthetic valve can include an expandable frame, a valve structure, a first end with apertures formed therein, and a second end. The delivery apparatus can include a valve catheter, flexible extension arms, slidable wires, and release members. First ends of the arms can be coupled to a cylindrical coupling element, second ends of the arms can be releasably coupled to the prosthetic valve, and the coupling element can be connected to the distal end of the valve catheter. The slidable wires can extend distally from the distal end of the valve catheter. The release members can be coupled to the distal end of the valve catheter and can extend through a respective aperture of the prosthetic valve, thereby forming a releasable connection between the prosthetic valve and the slidable wires.
