    摘要: The active introducer sheath systems disclosed herein are expanded by activating a translation mechanism at the handle. The sheath has an inner cylindrical structure of comingled fixed and mobile elongate rods bound together by an attachment line. Activating the translation mechanism causes the mobile rods to move axially with respect to the fixed rods, changing the internal tension in the attachment line. Increased tension draws the fixed and mobile rods closer together, decreasing the diameter of the cylindrical structure. Decreased tension in the attachment line enables the fixed and mobile rods to move apart, increasing the diameter of the cylindrical structure. A prosthetic device, such as a prosthetic heart valve, can be routed through the expanded sheath and to the implantation site. During implantation, the sheath can be contracted back to its original outer diameter, and expanded again for retrieval of the delivery apparatus.

    摘要: A stent graft crimping device for radially constricting a stent graft includes a rigid cylinder defining a slot extending parallel to a longitudinal axis of a flexible sheet having a straight edge and a second edge and extending within the rigid cylinder to define a pocket. In a method of use, a stent graft can be positioned within the pocket and radially constricted by pulling on the second edge of the flexible sheet while the straight edge, having a raised component, remains at the slot defined by the rigid cylinder. The stent graft crimping device can be employed independently or as a system in combination with components of a stent graft delivery device.

    摘要: A delivery system for deploying a medical implant includes a delivery wire assembly disposed within a delivery catheter lumen, the assembly having an implant loading region configured for seating the implant when the assembly is constrained within the delivery catheter lumen and the implant is in a compressed configuration, the assembly further including an implant distal protection having a central portion coupled to the assembly, distal of the implant loading region, and a peripheral portion extending proximally from the central portion to at least partially cover a distal end portion of the implant when the assembly, implant and distal protection are constrained within the catheter lumen, wherein the peripheral portion remains extending in the proximal direction when the implant assumes an expanded configuration after being released from the catheter lumen, and the peripheral portion of the distal protection comprises a plurality of stems, each comprising a respective petal-like member.

    摘要: A system (100) for identifying deformations of a deployed stent, is provided. The system includes one or more processors (110) configured to: receive (SI 10) X-ray image data representing one or more X-ray images (120) of a deployed stent (130) within a lumen (140), the stent including a plurality of stent struts (150): analyse (S120) the X-ray image data to determine a distribution of the stent struts (150) along an axis (160) of the lumen (140); and identify (S130) one or more longitudinally-deformed portions (170, 180) of the stent based on a density of the determined distribution of the stent struts (150) along the axis (160) of the lumen (140).
