  • Patent number: 11202702
    Abstract: A suture to be used in producing a medical instrument provided with a sutured site such as a stent graft, an artificial blood vessel or an artificial heart valve, has two components, i.e., a high melting-point component and a low-melting point component, the difference between the melting points of components being 30° C. or more and the low-melting point component is exposed on the suture surface entirely along the length direction. When a medical material formed of a fabric or a film is sutured or knotted with the suture and then the suture site is heated at such a temperature not allowing the high-melting point component but the low-melting point component alone to melt, the sutured site is fused and fixed. Thus, a knot or a seam, which sustains the fiber shape and strength and never becomes loose, can be formed.

  • Patent number: 11065096
    Abstract: Medical procedures and devices suitable for reducing the risk of embolic cerebrovascular events, including but not limited to cardioembolic stroke, that result from emboli entering the right or left common carotid artery. The invention uses a combination of intracranial flow diverting stent technologies and carotid stent technologies to achieve clinical objectives of embolic stroke prevention without thromboembolic and/or vascular stenosis complication. Such a stent has struts that generate high radial forces for endothelial apposition, and a mesh with interstices sufficiently small to prevent clinically significant-sized embolic material from passing therethrough from the common carotid artery into the internal carotid artery, but sufficiently large to enable blood and small clinically insignificant-sized embolic material to pass therethrough from the common carotid artery into the internal carotid artery.

The first conduit may be a branch vessel, such as a renal artery and the second conduit may be a main graft that extends over an aortic aneurysm. The branch graft may be deployed starting at an offset distance from the first end, thereby preventing the deployed portion from insertion into the first conduit and predetermining the insertion length into the target vessel. The first end may then be deployed to secure the first end to the first conduit. A branch graft may be a self-expanding stent graft having one or more ripcords, and/or a serpentine ripcord that enables non-linear deployment of the branch graft, or deployment that does not progress from one end to the opposing end.

  • 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: 10080674
    Abstract: A branched stent graft, a convey system comprising thereof and manufacturing method thereof, the branched stent graft includes a main body (100) and a side branch (200), at least a portion of a lowermost stent section of the side branch (200) closest to the main body (100) is not stitched to the cover of the side branch from a lower end to an upper end, the at least a portion of the lowermost stent section is located on a side of the side branch corresponding to a folding direction of the side branch. After deployed, the branched stent graft has an effective supporting force at the base portion of the side branch. In addition, during the deployment of the stent, the side branch can expand to a maximal extent even when the positioning is slightly inaccurate. Further, vascular stenosis or occlusion will not be caused even when subsequent endothelialization occurs.

  • Patent number: 10070950
    Abstract: A prosthetic assembly for repairing a target tissue defect within a target vessel region configured includes an exclusion structure sized to substantially bypass target tissue defect, and includes a branch assembly. The branch assembly can include a self-expanding outer branch prosthesis having an inflow region configured to deform to a non-circular cross-sectional-shape when deployed, and a support structure at least partially disposed within the inflow region. The support structure preserves blood flow to the branch vessel while the deformed inflow region inhibits blood leakage between and/or around the prosthetic assembly.

  • Patent number: 10004508
    Abstract: Disclosed is a medical device for shaping a vessel accommodated therein in a predetermined form, wherein said vessel includes a vein and an artery which are connected at a artifactual vascular junction thereof. The device includes an external vascular support (100) having at least one vascular support wall for accommodating an exterior vessel wall of a vessel therein when implanted. The support includes an arterial portion (1304) for apposition with said artery when accommodated therein, and/or a venous portion (1302) for apposition with said vein when accommodated therein. The venous portion (1302) and/or said arterial portion (1304) are shaped at a junction thereof to provide a vessel rounding to at least a portion of said vessel junction when in apposition with the latter upon implantation of said device for said vessel shaping. Corresponding methods are also disclosed. Thus dysfunction or failure of a vessel of the artifactual vascular junction may be reduced, minimized, or eliminated.

  • Patent number: 9993330
    Abstract: An endoluminal prosthesis system may include a main graft and an extension graft. The main graft may include a tubular main body having a sidewall, open proximal and distal ends, a lumen, and a fenestration in the sidewall. The extension graft may include a tubular extension body, and tubular first and second extension legs. Each of the first and second extension legs may extend from the extension body and include a lumen in fluid communication with the extension body lumen. The extension graft may be deployable within the main graft such that the extension body extends through the fenestration in the sidewall of the main body. Each of the first and second extension legs may extend outward away from the main graft. An auxiliary guide such as an auxiliary cannula and/or auxiliary guide wire may be preloaded in the extension graft and extend through the lumen of each of the second extension leg and the extension body.

  • Patent number: 9987122
    Abstract: An iliac branch device includes an iliac septum limb configured to be deployed in the common iliac artery. The iliac septum limb includes a graft material, a proximal end, and a septum. The graft material defines a common iliac lumen extending between the proximal end and the septum, the graft material and the septum defining an internal iliac lumen and an external iliac lumen. The iliac branch device including the iliac septum limb has several modes of adjustability. In addition, the iliac branch device has a relatively small cross-sectional area allowing the iliac branch device to treat relatively small iliac aneurysms in short common iliac arteries. This allows the iliac aneurysms to be treated at very early stages of the disease.

  • Patent number: 9801744
    Abstract: Described herein are flexible implantable occluding devices that can, for example, navigate the tortuous vessels of the neurovasculature. The occluding devices can also conform to the shape of the tortuous vessels of the vasculature. In some embodiments, the occluding devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. Some embodiments describe methods and apparatus for adjusting, along a length of the device, the porosity of the occluding device. In some embodiments, the occluding devices allows adequate blood flow to be provided to adjacent structures such that those structures, whether they are branch vessels or oxygen-demanding tissues, are not deprived of the necessary blood flow.
