  • Patent number: 10390977
    Abstract: A plaque tack can be used for holding plaque against blood vessel walls such as in treating atherosclerotic occlusive disease. The plaque tack can be formed as a thin, annular band for holding loose plaque under a spring or other expansion force against a blood vessel wall. Focal elevating elements and/or other features, such as anchors, can be used to exert a holding force on a plaque position while minimizing the amount of material surface area in contact with the plaque or blood vessel wall and reducing the potential of friction with the endoluminal surface. This approach offers clinicians the ability to perform a minimally invasive post-angioplasty treatment and produce a stent-like result without using a stent.

    Abstract: A self-expanding stent-graft provided in a diametrically compacted state for implantation and retained preferably by a constraining sheath, useful for the temporary or permanent repair of injured, partially or entirely transected body conduits including blood vessels. It may be used under direct visualization to quickly stop or substantially reduce loss of blood from such damaged vessels and to quickly re-establish perfusion distal to the injury site. The device would typically be implanted under emergency room conditions but also be used in field situations by trained medical technicians. After an end of the device is inserted into a blood vessel through the injury access, deployment preferably initiates from the device end in a direction moving toward the middle of the length of the device by directionally releasing the constraining sheath.

  • Patent number: 10154846
    Abstract: Various systems and methods are provided for reducing pressure at an outflow of a duct such as the thoracic duct or the lymphatic duct. In one embodiment, an indwelling catheter can be configured to be at least partially implanted within a vein of a patient in the vicinity of an outflow port of a duct of the lymphatic system. The catheter can include first and second restrictors each configured to at least partially occlude the vein within which the catheter is implanted and thus to restrict fluid flow within the vein when the restrictors are activated. The restrictors can each be configured to move between an activated configuration, in which the restrictor occludes the vein, and a relaxed configuration, in which the restrictor does not occlude the vein. The catheter can include a pump, such as an axial motor pump, configured to pump fluid through the catheter.

  • Patent number: 10123804
    Abstract: Described herein are flexible implantable devices or stents that can conform to the shape of vessels of the neurovasculature. In some embodiments, the devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. In some embodiments, a vascular remodeling device includes a first section and a protruding section. During deployment, the device expands from a compressed configuration to an expanded configuration. The first section anchors the device in an afferent vessel and/or in an efferent vessel of a bifurcation and the protruding section is positioned in the junction of the bifurcation having an aneurysm and across the neck of the aneurysm or at least partially within the aneurysm.

  • Patent number: 10117668
    Abstract: An angioplasty catheter comprises a catheter body having a balloon or other radially expandable shell at its distal end. An external structure is carried over the shell and scores a stenosed region in a blood vessel when the balloon is inflated therein. The catheter has an attachment structure disposed between the catheter body and the balloon to accommodate foreshortening and rotation of the external structure as the balloon is expanded. The external structure may be part of a helical cage structure which floats over the balloon. Stabilizing struts are provided between at least some of the helical struts.

  • Patent number: 10105245
    Abstract: This invention relates generally to an endoluminal prosthesis, and more particularly, to a stent graft assembly and method for treating branched vessels. The assembly includes a first prosthesis, such as an iliac branch device (IBD), comprising a tubular main body, a first leg extending from a distal end of the main body and at least one fenestration formed in the main body. An internal tubular side branch extends proximally from the fenestration into the lumen of the main body, resulting in an iliac branch device having an overall reduced proximal length. The assembly further includes a second prosthesis, or a bridging limb, having a distal end with a scalloped fenestration formed therein to accommodate sealing with the proximal end of the iliac branch device without interfering with the internal branch. A connecting stent graft adapted for placement in the internal iliac artery may be sealingly connected to the internal branch.

  • Patent number: 10076406
    Abstract: An endoluminal prosthesis for placement within a body vessel may include a tubular support structure including a proximal end segment, a distal end segment, an intermediate segment positioned between the proximal end segment and the distal end segment, a lumen extending longitudinally within the support structure, a luminal surface, and an abluminal surface opposite the luminal surface. The prosthesis may include a first layer of nonwoven electrospun fibers positioned on the luminal surface of the support structure. The prosthesis may include a second layer of nonwoven electrospun fibers positioned on the abluminal surface of the support structure. At least one of the proximal end segment or the distal end segment of the support structure may be encapsulated within a covering including the first layer of nonwoven electrospun fibers and the second layer of nonwoven electrospun fibers. The intermediate segment of the support structure may be unencapsulated within the covering.

  • Patent number: 10064745
    Abstract: A stent or scaffold has a tapered end or ends. The scaffold is made using an additive manufacturing technique such as stereolithography (SLA). The scaffold may take the shape of a frustum, or a scaffold having one or both of its ends flared. The scaffold has varying mechanical properties over its length, such as a varying ring stiffness, porosity or elasticity modulus. In one embodiment the strut and link widths change linearly from the distal to proximal ends.
