Patent number: 9295571Abstract: Described herein are flexible implantable devices or stents that can, for example, navigate tortuous vessels of the neurovasculature. The devices can also conform to the shape of tortuous vessels of the vasculature. In some embodiments, the devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. Methods and structures are provided for adjusting, along a length of the device, the porosity of the device while maintaining a cross-sectional dimension. In some embodiments, a distal stent cover covers the distal end of the device and reduces friction between the stent and an inner surface of a delivery device, such as a catheter.Type: GrantFiled: March 12, 2013Date of Patent: March 29, 2016Assignee: Covidien LPInventors: Gabriel F.

Patent number: 9289293Abstract: An improved holder and storage system for a tissue-type prosthetic mitral heart valve that constricts the commissure posts of the valve and prevents suture looping. A rod axially movable relative to the holder tensions lengths of attachment sutures that extend between the commissure post tips to create a tent and flex the tips inward, thus helping to prevent looping of any of an array of pre-implanted sutures around the leading tips during delivery of the valve. The holder has a safety mechanism that prevents valve delivery before the rod is deployed. One embodiment automatically deploys the rod upon opening a storage jar. One embodiment permits a delivery handle to directly deploy the rod, while another uses a separate worm screw and coupling. A holder clip that attaches to a packaging sleeve may be formed of flexible members meshed together from which the heart valve and holder are easily pulled free to eliminate a step of decoupling the clip from the sleeve.Type: GrantFiled: March 3, 2015Date of Patent: March 22, 2016Assignee: Edwards Lifesciences CorporationInventors: Michael C. Murad, Emil Karapetian, Wesley V. Adzich
