  • Patent number: 10327932
    Abstract: Catheter including a pressure chamber defined by proximal and distal seals and inner and outer tubular members. An actuator member, moveable between first and second positions, is disposed within the pressure chamber. Fluid introduced into the pressure chamber applies a force on the actuator member to move the actuator member toward the second position. A lock mechanism, disposed between inner and outer tubular members, includes a latch having an engaged condition preventing movement of the outer tubular member relative the inner member and a disengaged condition allowing movement the outer member. The latch is shifted to the disengaged condition when the actuator member is moved to the second position. With the actuator member in the second position and the latch in the disengaged condition, fluid introduced through the fluid flow port and into the pressure chamber applies a force on the proximal seal to urge the outer tubular member proximally.

  • Patent number: 8323327
    Abstract: A catheter system for implanting an endoprosthesis at a treatment site in a patient's body lumen. The catheter includes an elongated shaft outer member and a stent sheath distal portion and a self-expanding stent radially restrained in a collapsed configuration within the stent sheath distal portion. A balloon catheter dimensioned for relative axial movement within the shaft outer member has an elongated shaft having an inflation lumen and a device receiving lumen. A stent stop secured to the balloon catheter is reversibly radially expandable to deploy from a collapsed to a radially expanded configuration. In the expanded configuration, the stent stop prevents longitudinal displacement of the stent. A balloon is located on a distal shaft section is releasably locked with respect to the shaft outer member and slidably disposed therein in an unlocked configuration.

  • Publication number: 20100331951
    Abstract: A catheter system and method for implanting an endoprosthesis such as a stent at a treatment site in a patient's body lumen. The catheter provides a complete system for stent delivery, dilatation, and delivery and/or recovery of an expandable device, such as an embolic protection device, adjacent to the treatment site in the body lumen.

  • Publication number: 20080140003
    Abstract: A method of using a balloon catheter to perform a medical procedure at a treatment site in a patient's body lumen and to recover an expanded device, such as an embolic protection device, which is adjacent to the treatment site in the body lumen. The inflated balloon is deflated and regroomed to a low profile configuration in the body lumen, and the balloon catheter is advanced distally from the treatment site to collapse the expanded device (e.g., embolic protection filter) within the balloon catheter. The balloon catheter has a recovery distal tip for collapsing an expanded device, and has a regrooming sheath member configured to slidably receive the deflated balloon therein to regroom the balloon.

  • Patent number: 6596224
    Abstract: A powder bed (32) is built up by repeated deposition of a slurry that contains powder. Layers are made by depositing a liquid dispersion of the desired powdered material, which then slip-casts into the forming powder bed to make a new layer (34). The slurry may be deposited in any suitable manner, such as by raster or vector scanning, or by a plurality of simultaneous jets that coalesce before the liquid slip-casts into the bed, or by individual drops, the deposits of which are individually controlled, thereby generating a regular surface for each layer.
