  • Patent number: 11241320
    Abstract: An endoluminal prosthesis system for a branched body lumen comprises a branch vessel prosthesis. The branch vessel prosthesis is deployable within a branch vessel body lumen and comprises a stent having a generally tubular body portion, a flareable proximal end portion, and a coupling portion disposed intermediate the body portion and the flareable portion. The coupling portion is more crush-resistant than the body portion. The flareable proximal end may be disposed within a fenestrated stent graft with coupling portion disposed in the fenestration of the fenestrated stent graft.

  • Patent number: 8361135
    Abstract: An introducer for an expandable endovascular prosthesis having a self expanding stent has a distal prosthesis positioning mechanism and a proximal prosthesis retention mechanism. The proximal prosthesis retention mechanism includes a cylindrical sleeve adapted to retain the self expanding stent. A release mechanism extends proximally from the distal prosthesis positioning mechanism exerts a force in the proximal direction on the self expanding stent to retain the self expanding stent in the cylindrical sleeve.

  • Patent number: 7968038
    Abstract: A large diameter, flexible, kink-resistant, delivery catheter or sheath for percutaneous delivery of a contained and implantable medical device in the vasculature of a patient. The delivery catheter or sheath includes a reinforcement such as a flat wire coil with uniform spacing between the turns, which is compression fitted about an inner, lubricous PTFE tube. The delivery catheter or sheath further includes an outer tube of a heat formable polyamide material which is heat formed and compressed through the spaces between the turns of the wire coil to mechanically connect to a roughened outer surface of the inner tube. A polymeric radiopaque marker tube may be positioned at the distal end of the coil and between the inner and outer tubes for radiographic visualization. A side port may also be positioned thereat for the infusion of contrast media.

  • Patent number: 7704245
    Abstract: A large diameter delivery catheter or sheath for percutaneous delivery of a contained and implantable medical device in the vasculature of a patient. The delivery catheter or sheath includes a reinforcement such as a flat wire coil with uniform spacing between the turns. The reinforcement is compression fitted about an inner, lubricous PTFE tube having a substantially uniform inner diameter of from 16 to 30 French. The delivery catheter or sheath further includes an outer tube of a heat formable polyamide material having a durometer of about 30 to 60 on the Shore D scale. The outer tube is heat formed and compressed through the spaces between the turns of the wire coil to mechanically connect to a roughened outer surface of the inner tube. A polymeric radiopaque marker tube may be positioned at the distal end of the coil and between the inner and outer tubes for radiographic visualization.

  • Publication number: 20060095050
    Abstract: A large diameter, flexible, kink-resistant and rotatable introducer sheath (10) for percutaneous delivery of a contained and implantable medical device in the vasculature of a patient. The introducer sheath includes a reinforcement such as a flat wire coil (23) fitted about an inner, lubricous material such as polytetrafluoroethylene tube (22). A wire braid (25) is placed around the coil to give good transfer of rotational forces. An outer tube (27) of a heat formable polyamide material is heat formed and compressed through the spaces between the wires of the braid and turns of the wire coil to mechanically connect the outer tube to the roughened outer surface of the inner tube. The durometer of the outer tube can be varied to effect the flexibility of the sheath. A radiopaque marker (42) is positioned at the distal end of the coil and around the inner tube for radiographic visualization.
