  • Patent number: 8057529
    Abstract: A stent delivery system for implantation of a stent in a vessel 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. The proximal end of the outer tubular member is attached to a pull-back handle which is slidably mounted on the base of the housing assembly. When the pull-back handle is retracted, the restraining sheath is retracted to deploy the sheath, while the inner tubular member remains stationary.

  • 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.

  • Publication number: 20080053458
    Abstract: A nasally introduced catheter (nasal catheter) has a portion in which a user's breath (breathing air) air travels internally and a portion in which the breath travels externally. The portion in which air flow travels internally preferably includes a mesh or a whisk-like portion that expands and contracts, and the portion in which air flow travels externally preferably comprises a proximal tubular element having a sufficiently small cross-sectional area that at least 50% of the breathing air flows externally to the proximal portion. A sheath can optionally be positioned about the distal portion, and pulled back along the proximal portion to allow the distal portion to expand.

  • Patent number: 6893458
    Abstract: A self-expanding stent for implantation into a body lumen, such as an artery, includes 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 to create at least one continuous spine which extends along the length of the stent. The cylindrical elements are nested when placed in a collapsed position. The cylindrical elements may include a W-shared portion to which the interconnecting members attach.
