  • Patent number: 10028854
    Abstract: A stent delivery system includes an expandable stent, a catheter, and a sheath. The expandable stent includes proximal and distal ends, and a first interlock structure. The catheter includes an elongated member having a second interlock structure displaceably arranged about an outer surface thereof for engaging the first interlock structure of the stent. The sheath is mounted on the elongated member and is positionable in a transport position in which the sheath covers the stent mounted on the elongated member and a deploy position in which the stent is exposed.

  • Publication number: 20070135826
    Abstract: A system and method for delivering an implant includes an implant, an actuation shaft, and a concentrically attachable disconnect mount. A distal guide tube is sometimes also provided. A proximal guide tube is also sometimes provided. The implantable device has a proximal, a distal end, and a plurality of supports. The implantable device is moveable between a collapsed and an expanded configuration. The distal guide tube, when provided, is at the distal end of the supports and extends toward the proximal end of the implantable device. The actuation shaft extends through the proximal end of the implantable device and is removeably engageable with the distal guide tube, or the distal end of the device when the distal guide tube is not provided. The disconnect mount is releasably engageable with the proximal end of the implantable device. The disconnect mount is concentrically attachable to the proximal end of the implantable device as well.

  • Publication number: 20070129785
    Abstract: A renal stent includes a balloon expandable segment intended for deployment in the renal vessel and a self expanding segment intended for deployment in the aortic segment. One or both of the balloon expandable and self expanding segments can be deployed in the ostial region of the renal vessel, typically the renal artery. The balloon expandable segment provides superior radial strength for maintaining dilated diameter of the renal vessel. The self expanding segment expands to conform to the flared ostial and aortic regions of the vessel. The self expanding segment can be balloon dilated to enhance conformance of the self expanding stented segment to the ostial and aortic regions.
