  • Patent number: 10322021
    Abstract: Several gastrointestinal surgery procedures are effective as treatments for metabolic disorders such as obesity and diabetes. Minimally invasive procedures including intra-luminal gastrointestinal implants have been proposed to mimic the anatomical, physiological and metabolic changes achieved by these procedures. Many of these designs include long sleeve like elements that prevent contact of food with the walls of the small intestine. It is desirable to have simple delivery systems that can place these implants under endoscopic guidance. However, in order to anchor these sleeve elements safely and reliably, the inventors have previously disclosed anchoring means that anchor the sleeves at the junctions of the stomach and the intestine or the stomach and esophagus.

  • Patent number: 9636208
    Abstract: A vascular prosthesis is disclosed, comprising a forked tube, having: an inflow tube with an inflow end; a primary distal outflow branch with a primary distal outflow end; and a secondary proximal outflow branch with a secondary proximal outflow end. The two outflow ends are directed in different directions and the two outflow branches in the vicinity of the bifurcation have different cross-sectional areas. Further, the secondary proximal outflow branch is more curved than the primary distal outflow branch, and the secondary proximal outflow branch in the vicinity of the bifurcation has a smaller cross-sectional area than the primary distal outflow branch. Hereby, energy losses at flow bifurcations is adapted to the bypass situation to even out the level of shear stress, thereby avoiding areas with low shear stress and decreasing the tendency for turbulent flow, thus reducing the risk of graftstenosis.

  • Patent number: 9301861
    Abstract: Stents and method of inserting a stent into a delivery catheter are disclosed. In a disclosed embodiment, a stent for redirecting blood flow away from an aneurysmal sac is provided. The stent comprises an elongate frame (2) that is radially contractable from a fully radially expanded state to a radially contracted state in a process involving elongation of the frame, wherein: the fully radially expanded state represents the state of the frame at body temperature when no external force is applied to the frame; in the radially contracted state the frame has a maximum lateral dimension that is at least 30% smaller than the maximum lateral dimension of the frame in the fully radially expanded state; and the frame comprises a low porosity region (4) for positioning at the opening to the aneurysmal sac, the low porosity region having a porosity of less than 50% when the frame is in the fully radially expanded state.

  • Patent number: 9296011
    Abstract: An interventional device for delivery of beneficial agent to a lumen and methods of loading and manufacture of the same, which include a prosthesis loaded with beneficial agent to provide a controlled dosage concentration of beneficial agent to the lumen. The beneficial agent is loaded onto the prosthesis by a fluid-dispenser having a dispensing element capable of dispensing the beneficial agent in discrete droplets, each droplet having a controlled trajectory. The interventional device has a controlled local areal density of beneficial agent for systemic delivery or delivery to the luminal wall. The local areal density of beneficial agent may be varied along the prosthesis. The interventional device includes overlapping or bifurcated stents having a controlled areal density of beneficial agent.

  • Patent number: 9265599
    Abstract: A delivery system for an endoluminal device including an introducer, the introducer having a distal end intended to remain outside a patient in use and a proximal end. A stent graft having a first and second end is retained upon the introducer, the stent graft defining a fenestration disposed through a wall of the stent graft between the first and second end. A valve arrangement is disposed within an interior lumen of the stent graft about the fenestration. A retention system including a trigger wire engages and retains the valve arrangement away from the fenestration. The fenestration is in fluid communication with the interior lumen of the stent graft.

  • Patent number: 9241793
    Abstract: A valve prosthesis device and methods for deployment is disclose. The device comprises an expandable support stent and a valve assembly comprising a flexible conduit having an inlet end and an outlet, made of pliant material attached to the support beams providing collapsible slack portions of the conduit at the outlet. Flow is allowed to pass through the valve prosthesis device from the inlet to the outlet, but reverse flow is prevented as the collapsible slack portions of the valve assembly collapse inwardly. The device is configured so that retrograde flow will be altered from laminar flow and directed towards the leaflets to effect closing. The device can be deployed in a native heart valve position using a deployment catheter advanced through a body lumen such as a blood vessel, including an aorta.

  • Patent number: 9168160
    Abstract: A fenestrated implantable medical device, such as a stent graft (10) is provided with a plurality of zigzag stents (12) of which two or more form fenestrations (34, 36) using part of the stents (12) as a support frame (30, 32) for the fenestrations (34, 36). The frames (30, 32) are preferably covered by radiopaque wire (44) coiled around the stent structures. The radiopaque coil (44) provides easy reference to the fenestrations (30, 32) for imaging purposes.

  • Patent number: 9161831
    Abstract: A modular stent graft system and methods of assembly are disclosed. The stent graft assembly comprises a first stent graft having an interface region at its distal end and a first locking stent secured to an internal surface of the interface region. A second stent graft having an interface region at its proximal end is configured to at least partially overlap with the interface region at the distal end of the first stent graft. The second stent graft comprises a second locking stent secured to an external surface of the interface region. The first and second locking stents are configured to be engaged such that the second locking stent is nested between the first locking stent and an internal surface of the interface region of the first stent graft thereby interlocking the first and second stent grafts to each other.

  • Patent number: 9095461
    Abstract: An endoluminal vascular repair system includes an aorta stent graft having a fenestration with a first reinforcement around the fenestration. The fenestration aligns with a branch vessel when deployed. A branch vessel stent graft has a flaring portion at a proximal end of the branch vessel prosthesis that has a second reinforcement around its circumference to engage the reinforcement around the fenestration, and a tubular portion. When deployed, the flaring portion retains the proximal end within the aorta stent graft, and the tubular portion extends through the fenestration and into the branch vessel.

  • Patent number: 9066824
    Abstract: Assemblies, devices, and methods for positioning the same proximate a target site within a body lumen are provided. The assembly includes first and second components that can function independently of one another to address a patient's vascular abnormalities or can cooperate to form an assembly. The assembly is designed to address aortic pathologies near clusters of arterial branches in a way that allows blood to continue flowing to the arterial branches during the procedure while providing an adequate landing zone for the adjoining component. One of the components may include a tapered portion near one end that can be received by a corresponding end of the other component. Alternatively, one of the components may include an invaginated end that is able to receive a corresponding end of the other component such that the position of each component is substantially fixed with respect to the other.

  • Patent number: 9050182
    Abstract: A stent/graft assembly includes a tubular graft connected in substantially end-to-end relationship with a generally tubular stent. Free ends of the stent and graft extend in opposite directions from the end-to-end connection during a pre-deployment orientation of the assembly. However, the graft is inverted during deployment so that free ends of the graft and the stent extend in substantially the same direction from the end-to-end connection in a post-deployment orientation. Thus, at least a portion of the stent is disposed within at least a portion of the graft in a post-deployment orientation of the assembly.
