  • Patent number: 9375336
    Abstract: A delivery device can provide sequential delivery of a plurality of intraluminal devices or tacks held in a compressed state on the delivery device. Delivery platforms on the delivery device can hold a tack in a compressed position and have a unique shape, such as a non-constant outer diameter, an hourglass shape, a tapered proximal half, ridges, dimples, etc. This unique shape can be positioned between annular pusher bands that may also be radiopaque markers. In some embodiments, the unique shape is provided by a sleeve of flexible material with the unique shape surrounding a harder inner shaft. Further, the annular pusher bands can be made of wire or sections of material to increase flexibility while remaining radiopacity. A tack deployment method can include alignment of radiopaque markers on the outer sheath and the tack to be deployed prior to deployment.

  • Patent number: 8485961
    Abstract: Disclosed herein are heart pumps that include a catheter assembly and that can be applied percutaneously. Some embodiments include a locking device that prevents components of the catheter assembly from being separated when in use. The catheter assembly can include an expandable tip. In some embodiments, the catheter assembly includes a housing having a wall structure, a portion of which can have a bulbuous shape or can be deformable. In other embodiments, the housing can be configured to reduce fluttering or deflection of the housing and/or to maintain a gap between the housing and an impeller blade disposed therein.

  • Publication number: 20100034748
    Abstract: The present invention relates to a loaded reactive nanoscale latex particle synthesized from mixture of monomers containing water insoluble monomers, at least two ethylenically functionalities monomers, halo-aromatic-polyethyleneglycol-methacrylate, polyethyleneglycolacrylate containing macromonomers, and up to 10 wt % other ethylenic monomers different from above monomers. The reactive halo-aromatic groups on the surface of latex particle are servable as linkers to react with peptides, antibodies, nucleic acids, ligands or other biomolecules.

  • Publication number: 20090082843
    Abstract: The invention is directed to a self-expanding stent for implantation into a body lumen, such as an artery. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common longitudinal stent axis and interconnected by a plurality of interconnecting members placed on the stent in a collinear arrangement such as to create at least one continuous spine which extends along the length of the stent. The invention is also directed to a stent delivery system for implantation of a stent in a vessel which includes an outer tubular member having a restraining sheath and an inner tubular member having a distal end which has a compressed stent mounted thereto. The proximal end of the inner tubular member is connected to a housing assembly which prevents the inner tubular member from moving when the outer tubular member is retracted to deploy the stent.

  • Patent number: 6997944
    Abstract: An expandable intraluminal stent having a strut pattern made from a plurality of triangular cells is disclosed. Each triangular cell is formed from at least two V struts of different magnitudes aligned in phase and joined at opposite ends forming two opposed vertices of the triangle. A series of triangular cells are joined at the vertices to form a ring. The series of triangular cells may be arranged to form peaks in the ring, peaks and valleys in the ring, or a combination thereof. A plurality of the rings are aligned coaxially and joined by connecting elements to form a tubular shape. Use of the double V strut formation in the rings increases vessel wall coverage, reduces gap sizes, and does not impair the compressability of the stent for a small profile for delivery.
