Catheter system and methods of using same

摘要

A modular catheter system including a sheath projecting distally from a delivery catheter having a main body module An inner core module carrying a stent thereon, the inner core being axially movable through the main body of the delivery catheter and the delivery catheter sheath, a handle member supported by the main body of the delivery catheter, the handle member being selectively axially engageable with the inner core such that the handle member and the inner core move together in an axial direction when the handle member is engaged with the inner core; and an adjustment member supported by the main body, the adjustment member being configured such that rotation of the adjustment member causes the adjustment member to move axially along the main body by either axially sliding the handle member relative to the main body or by rotating the adjustment member.

1. A delivery catheter system configured to deliver a stent, the delivery catheter system comprising:
a main body having a proximal end portion and a distal end portion; an outer sheath projecting from the distal end portion of the main body; a first restraint for restraining a main body portion of the stent; a second restraint for restraining a branch portion of the stent; a first hollow release wire axially coupled with the second restraint; a second wire having a proximal and a distal end portion, the second wire advanced into the first hollow release wire in a stent loaded state such that at least a portion of the hollow release wire is coaxial with the second wire; wherein a bend formed in the first hollow release wire removably locks a distal end portion of the second wire to the first hollow release wire.
