A branch stent for implantation from a main blood vessel in a plurality of branch blood vessels having respective branch blood vessel diameters, the branch stent comprising: a tubular element having: an axis of elongation; a first and a second tubular element end; the tubular element covered with a tubular element cover; and a parachute element having an unconstrained flat-toroid/disc configuration, the parachute element having a parachute element cover, the parachute element positioned perpendicularly at the second tubular element end, and positioned coaxially to the axis of elongation; wherein the branch stent is implanted from within a fenestrated stent-graft having oversized fenestrations, the fenestrated stent-graft first implanted in the main blood vessel at a bifurcation zone including the plurality of branch blood vessels, with each of the oversized fenestrations having respective diameters larger than respective branch blood vessel diameters; wherein the branch stent and the fenestrated stent-graft are together a multi-stent.

Branch stent for implantation from a main blood vessel and deployment methods

The present invention provides an intracardiac device suitable for minimally-invasive delivery, wherein said device comprises a device body and one more stabilizing elements attached to said device body. The stabilizing elements may be selected from the group consisting of: stabilizing wings having at least one portion with a thickness greater than that of the device body, wings comprising one or more auxiliary support arms, wings having a metal wire coil wound around them, wings having a leaf spring attached thereto, polymer-coated stabilizing wings, and mechanical stabilization elements comprising a rotatable jaw-like structure.

Intracardiac devices comprising stabilizing elements having improved fatigue resistance

A multi stent delivery system for intravascular bifurcation zone delivery and deployment of a multi stent, the bifurcation zone having a main blood vessel, the main blood vessel having a main blood vessel longitudinal axis and at least one side blood vessel inclined/branching out of the main blood vessel, the delivery system comprising: a catheter having a catheter longitudinal axis substantially coaxial with the main blood vessel longitudinal axis, a tube positioned coaxially within the catheter, the catheter having a distal end and a proximal end, and the tube containing: at least one crimped side stent for deployment substantially normal to the catheter longitudinal axis and into the side blood vessel; and at least one crimped main stent for deployment substantially along the catheter longitudinal axis into the main blood vessel; wherein the at least one crimped side stent and at least one crimped main stent are part of a unified/singular configuration within a sheath, located substantially at the distal end.
