  • Patent number: 10624772
    Abstract: An aneurysm bridging device can be placed in the neurovasculature of a patient by advancing the aneurysm bridging device in a small-diameter configuration a delivery catheter to a target region within the neurovasculature and securing the distal region of the aneurysm bridging device to the neurovasculature. While the distal region of the aneurysm bridging device is secured to the neurovasculature, the proximal region of the aneurysm bridging device can be advanced to permit the aneurysm bridging device to expand from the small-diameter configuration and to deform and twist in a central region of the aneurysm bridging device. The proximal region of the aneurysm bridging device can be secured within the neurovasculature to maintain the central region of the aneurysm bridging device in a deformed state.

  • Patent number: 9827093
    Abstract: A method for implanting a stent includes contracting a self-expanding/forcibly-expanding stent of a shape-memory material set to a given shape to a reduced implantation size with a delivery system having drive wires. The stent has a selectively adjustable assembly with adjustable elements operatively connected to the drive wires such that, when the adjustable elements are adjusted by the drive wires, a configuration change in at least a portion of the self-expanding stent occurs. The contracted stent is inserted into a native annulus in which the stent is to be implanted. The drive wires are rotated with the delivery system to forcibly expand the stent into the native annulus. While rotating the drive wires, a torque applied to the drive wires is determined with the delivery system. Rotation of the drive wires is stopped based upon a value of the determined torque.

  • Patent number: 9526641
    Abstract: The current invention employs tubes that can be constrained and expanded by either axial or torsional strain. By torsionally displacing the tube in a direction counter to the biased helices and angularly displacing the lower angle helix to an angle equal to, but opposite, the starting angle, the tube is expanded diametrically with no significant change in length after expansion of the tube. These tubes find utility in medical and non medical applications.

  • Patent number: 9440302
    Abstract: An assembly and planar structure for use therein which is expandable into a 3-D structure such as a stent and device for making the planar structure are provided. The planar structure permits the use of planar batch manufacturing technologies to fabricate coronary artery stents. Stents with different wall patterns are fabricated from 50 ?m thick stainless steel foil using micro-electro-discharge machining, and expanded to tubular shapes by using angioplasty balloons. The stents are free-standing. The free-standing stents exhibit diameter variations of <±4%, almost zero radial recoil after deflation of the balloon, and longitudinal shrinkage of <3% upon expansion. A variation of the stents uses breakable links to provide additional customization of electrical and mechanical properties. Loading tests reveal that the radial strengths match commercially available stents, while longitudinal compliance, at 0.02 m/N for a 4 mm long section of the stent, is substantially higher.

    Abstract: The inventions relate generally to expandable medical implants for maintaining support of a body lumen and, in particular, to an axially nested, diametrically expandable, slide and lock vascular device for enlarging an occluded portion of a vessel. The axially nested vascular device desirably achieves both competitive crossing profiles while maintaining other key features, such as, for example, radial strength and luminal patency. The collapsed profile can also be made very thin without compromising radial strength. Thus, the vascular device can advantageously be deployed in small and difficult to reach areas or vessels. The axial nesting substantially eliminates radial overlap between mating structural elements thereby desirably allowing for a low, uniform profile.

  • Patent number: 8034099
    Abstract: A generally tubular, cylindrical stent prosthesis has an unexpanded delivery configuration and an expanded configuration for contacting the vessel wall. The stent prosthesis has a plurality of adjacent stent struts, each stent strut having a wavelike or sinusoidal pattern of straight segments and crowns. A Y-shaped member is attached to one or more crowns to cause the crowns to flare outwardly at an angle from the cylindrical stent body when the stent is expanded. Upon expansion of the stent, the crown(s) having Y-shaped members attached thereto are angled with respect to the longitudinal axis and radially flare from the cylindrical stent body. The flared crowns anchor the stent within the vessel by protruding into the vessel wall and/or seating the stent within an ostium.

  • Patent number: 8007527
    Abstract: A intraluminal stent comprises a reticulated tube having an un-deployed diameter and expandable to an enlarged diameter. The tube includes a structural beam extending between first and second ends. The structural beam changes from a first geometry to a second geometry when the tube changes from the un-deployed diameter to the enlarged diameter. The structural beam includes first and second longitudinal elements each extending at least partially between the first and second ends and with a spacing between the first and second elements. Each of said first and second elements changes from the first geometry to the second geometry when the tube changes from the un-deployed diameter to the enlarged diameter for the spacing to remain substantially unchanged as the tube changes from the un-deployed diameter to the enlarged diameter.

  • Patent number: 7998193
    Abstract: An intravascular stent especially suited for implanting in curved arterial portions or ostial regions. The stent can include an end region which is fabricated to have a greater radial strength than the remaining axial length of the stent. Such a stent is particularly suited for use in ostial regions, which require greater support near the end of the stent. The stent alternatively can include sections adjacent the end of the stent with greater bending flexibility than the remaining axial length of the stent. Such a stent is particularly suited for use in curved arteries. The stent can also be constructed with an end that has greater radial strength and sections adjacent the end with greater bending flexibility. Such a stent prevents flaring of the stent end during insertion.

  • Patent number: 7959662
    Abstract: A endovascular prosthesis for implantation in a body passageway. The prosthesis comprises a tubular wall which is: (i) movable between a first longitudinal length and a second longitudinally length, and (ii) radially expandable for implantation of the prosthesis in the body passageway. In one embodiment, the tubular wall has a longitudinally length which is variable by an “accordion”-like action. In another embodiment, the tubular wall has a longitudinally length which is variable by an “telescoping”-like action. The longitudinal length of the tubular wall may be varied in vivo to optimize deployment of the endovascular prosthesis.

  • Patent number: 7914574
    Abstract: The invention relates generally to expandable medical implants for maintaining support of a body lumen and, in particular, to an axially nested, diametrically expandable, slide and lock vascular device for enlarging an occluded portion of a vessel. The axially nested vascular device desirably achieves both competitive crossing profiles while maintaining other key features, such as, for example, radial strength and luminal patency. The collapsed profile can also be made very thin without compromising radial strength. Thus, the vascular device can advantageously be deployed in small and difficult to reach areas or vessels. The axial nesting substantially eliminates radial overlap between mating structural elements thereby desirably allowing for a low, uniform profile.

  • Publication number: 20110004294
    Abstract: A fatigue-resistant implantable medical device. The fatigue-resistant implantable medical device includes a tubular stent. The tubular stent can have a laser-cut length and a shape-set length that is either longer or shorter than the laser-cut length. Such stents will tend to return to their laser-cut length when they are compressed for delivery. A stent that is shape-set longer than its laser-cut/delivery length that is deployed in a vessel that is shortened for stent delivery will tend to return to its shape-set length when the vessel returns to its neutral (i.e., elongated) length. Likewise, a stent that is shape-set shorter than its laser-cut/delivery length that is deployed in a vessel that is elongated for stent delivery will tend to return to its shape-set length when the vessel returns to its neutral (i.e., shortened) length. Such stents will experience reduced axial loading and reduced mean strain, thereby improving fatigue life.

  • Patent number: 7853340
    Abstract: A method for aligning a stent with a stent support includes the steps of (1) placing a stent support and a stent mounted on the stent support in a vertically position with the stent support's first support element at a lower position and the stent support's second support element at an upper position; (2) obtaining a digital image of the stent support and stent; (3) analyzing the digital image of the stent support and stent to compute the vertical position of the stent's upper end; (4) computing a desired position of the second support element based on the position of the stent's upper end; and (5) using a positioning device to move the second support element to the desired position. The movement of the second support element causes the conical sections of the first and second support elements to engage the respective ends of the stent to center the stent around a core element of the stent support and to secure the stent in a longitudinal direction of the stent support.
