A catheter pump includes an elongate cannula with a formed mesh structure extending cylindrically between opposing ends thereof. The formed mesh structure defines a pattern configured to be stably expandable and collapsible without fracturing in a percutaneous delivery and re-sheathing in the provision of mechanical circulatory support of a patient's heart.

A stent includes a high radial force segment and a highly flexible segment, where the diameters of the high radial force segment and the highly flexible segment are substantially the same. The stent may further be placed with an additional stent segment, where the additional stent segment has a radial force similar to the radial force of the highly flexible force segment.

Hybrid stent

Self-expending stents that include circumferential rings of alternating interconnected struts connected by flexible connectors. The struts of the rings and flexible connectors have a structure, including areas of expanded or reduced width or thickness, to account for venous applications. When used for venous applications, the stents convey benefit from configurations that improve flexibility (due to the greater elasticity of venous applications) while maintaining enough stiffness to resist pressure on the venous structure in selected areas (such as for the May-Thurner syndrome). The stents include particular structural characteristics—often expressed as ratios between different measurements—that are particularly advantageous for (although not limited to) venous applications.

Non-foreshortening stent

A radially expandable, tubular stent, includes a first section having a first crush resistance force and a second section have a second crush resistance force, wherein the first crush resistance force is less than the second crush resistance force. The first section is connected to the second section to form a tube, connection of the first and second sections extending in an axial direction of the tube.

Intravascular implants

Implantable stents that include strips that are each comprised of main struts connected by first connectors, and adjacent strips are connected by second connectors. The strut connectors have a structure, including areas of expanded or reduced width or thickness, to account for venous applications. When used for venous applications, the stents convey benefit from configurations that improve flexibility (due to the greater elasticity of venous applications) while maintaining enough stiffness to resist pressure on the venous structure in selected areas (such as for the May-Thurner syndrome). The stents include particular structural characteristics that are particularly advantageous for (although not limited to) venous applications.

A system for efficiently and ergonomically waterproofing a weakness area of a roof. The system includes an airless sprayer system capable of attaching to one or more attachments. The airless sprayer system is connected to a reservoir containing a waterproofing liquid. The attachments include an encapsulating attachment and a duckbilled attachment, either attachment capable of connecting to an extending wand. The system may be used atop a roof by either placing the encapsulating attachment over a fastener or the duckbilled end over a seam and pulling the trigger of a spray gun of the airless sprayer system until either the fastener or seam are sufficiently covered in waterproofing liquid. By connecting the wand therebetween the spray gun and the attachment, the user of the system may be able to remain standing when applying the waterproofing liquid. A method for efficiently and ergonomically waterproofing a roof weakness using the system.

A catheter pump is provided that includes a rotatable impeller and an elongate cannula. The elongate cannula has a mesh that has a plurality of circumferential members disposed about the impeller. The elongate cannula has a plurality of axial connector extending between a proximal side of a distal circumferential member and a distal side of a proximal circumferential member. The circumferential members are radially self-expandable. The cannula is configured to minimize fracture within at least in the distal zone of the mesh as the elongated cannula moves into a sheathing device.

A stent includes a high radial/crush force segment and a highly flexible segment. In an aspect, a plurality of first ring struts connected such that each of the plurality of first rings comprises a sinusoidal pattern having a plurality of apices and troughs, each first ring connected to an adjacent first ring by at least one connector. The connector extends from a ring strut of the first ring from a position near an apex of the first ring to a ring strut of the adjacent first rings near an apex of the adjacent ring, and a second stent segment comprises a plurality of second rings connected to one another to form a series of second rings.

A stent includes a high radial force segment and a highly flexible segment, where the diameters of the high radial force segment and the highly flexible segment are different. For example, the stent may be formed from a tube having varying diameters as it extends distally combined with increased strut density to achieve increased flexibility distally while reducing loss of radial stiffness. The stent may further be placed with an additional stent segment, where the additional stent segment has a radial force similar to the radial force of the highly flexible force segment.
