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.

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 preferably more crush-resistant than the body portion.

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.

Prosthesis deployment system

A method for producing a radially expandable prosthesis by cutting a pattern in a tubular member, which member has an outer diameter at least as great as the expanded diameter of the prosthesis.

Method of producing a radially expandable prosthesis

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.

Large diameter delivery catheter/sheath

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.

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 and exerts a force in the proximal direction on an interior surface of the self expanding stent to retain the self expanding stent in the cylindrical sleeve.
