Abstract: A medical stent includes an inner metallic tubular member including a plurality of interconnected struts defining the inner metallic tubular member, and an outer metallic tubular member circumferentially surrounding the inner tubular member. The outer metallic tubular member includes one or more filaments knitted together in a plurality of loops that together form the outer metallic tubular member. The outer metallic tubular member is secured relative to the inner metallic tubular member. The inner tubular member exerts a radially outward force on the outer tubular member in a radially expanded configuration.

Abstract: Embodiments in the present disclosure relate to an anchoring and centering device for a circulatory support pump. An exemplary apparatus comprises an expandable anchoring device extending along a longitudinal axis, wherein the expandable anchoring device is arranged about a central axis. A distal portion of the expandable anchoring device defines an annulus through which the cardiac pump can be arranged and to which the cardiac pump can be releasable coupled. A proximal portion of the expandable anchoring device is configured to circumferentially expand to an unconstrained configuration that has a cross-sectional diameter greater than a diameter of the annulus. The exemplary apparatus also includes a constraining member arranged over the expandable anchoring device to constrain the expandable anchoring device in a constrained configuration for delivery of the anchoring apparatus.

Abstract: A thrombectomy apparatus for removing a clot from a vessel includes a catheter defining a lumen extending proximally from a distal end. A funnel is secured to the distal end and extends distally therefrom, the funnel includes a braided inner layer and a braided outer layer, the braided outer layer folded over the braided inner layer and adapted to constrain the braided inner layer. A tractor is adapted to extend over an outer surface of the catheter and the funnel in an un-inverted configuration and to extend in an inverted configuration through the funnel and into the lumen, the tractor adapted to invert by rolling over the distal end of the funnel when the tractor moves proximally. A puller extends through the lumen and is secured to an end of the tractor disposed within the lumen.

Abstract: An endoprosthesis for preventing collapse of a vein may include an expandable framework configured to shift between a radially collapsed configuration and a radially expanded configuration, and a plurality of anchoring legs extending axially away from a first end of the expandable framework. The plurality of anchoring legs may be configured to shift between a delivery configuration and a deployed configuration. In the deployed configuration, the plurality of anchoring legs may be configured to extend radially outward of the expandable framework in the radially expanded configuration. A system for preventing collapse of a vein may include a delivery catheter having a lumen, an endoprosthesis disposable within a distal portion of the lumen in a radially collapsed configuration, and at least one filament coupled to the plurality of anchor legs of the endoprosthesis and extending within the lumen of the delivery catheter.

Abstract: Devices and methods for assisting blood flow are provided. The device includes a housing with an inlet and an outlet, and a fluid barrier separating the housing into a first section containing the inlet and outlet, and a second section. The device also includes an impeller shaft coupled to an impeller and a first magnet in the first section of the housing, and a drive shaft coupled to a second magnet in the second section of the housing. The first and second magnets are arranged such that rotation of the drive shaft rotates the second magnet causing rotation of the first magnet, which drives the impeller.
