  • Patent number: 7959661
    Abstract: A delivery system for delivering an endoluminal implant to a distal deployment location inside a body lumen from a proximal access location outside the lumen. The system includes the implant, a catheter, and a slidable sheath having an advanced position in which the sheath covers the implant and a retracted position in which the implant is exposed. The catheter includes a stabilizer having a distal end adjacent the implant proximal end and/or a catheter tip attached to a central core slideably disposed relative to the implant and having a proximal end adjacent the implant distal end. The catheter tip proximal end and/or the stabilizer distal end includes a docking section adapted to releasably engage a portion of the implant. Each docking section has an engagement geometry including a flared engagement surface that extends inside a short axial length of the implant or a pocket having a bottleneck geometry.

  • Patent number: 6858034
    Abstract: A stent delivery system adapted to deliver a compressed stent to a distal deployment location inside a body lumen from a proximal access location outside the body lumen. The system houses a compressed stent and includes a pusher and a catheter tip attached to a central core slideably disposed within the pusher. At least one of the pusher distal end and catheter tip proximal end comprises a docking section adapted to releasably engage a limited length of one end of the compressed stent. The docking section may comprise a pocket having a flared end rim that is radially biased outward and adapted to be inwardly compressed to grip the stent end when the docking section is loaded in an outer sheath. Other docking section configurations are also disclosed, such as an insert within the stent, an annular pocket, and/or a set of fingers that grip the stent.
