CATHETER SYSTEM AND METHODS OF USING SAME
First Claim
1. A catheter system comprising:
- a delivery catheter comprising;
a main body having a proximal end portion and a distal end portion;
a delivery catheter sheath projecting distally from a distal end portion of the main body;
an inner core configured to a support a stent thereon, the inner core being axially advanceable 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 delivery catheter being configured such that the handle member and the inner core move together in an axial direction when the handle member is connected to 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;
wherein the handle member is axially moveable along the main body of the delivery catheter between the distal end portion of the main body and the adjustment member by either axially sliding the handle member relative to the main body or by rotating the adjustment member relative to the main body when the adjustment member is rotated to provide an axial contact force with the handle member.

Abstract
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.

19. A 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; an inner core configured to a support a stent thereon, the inner core being axially advanceable through the main body of the delivery catheter and the outer sheath; a handle member supported by the main body of the delivery catheter, the handle member being axially coupled with the inner core such that the handle member and the inner core move together in an axial direction; and an adjustment member supported by the main body of the delivery catheter, the adjustment member being configured such that rotation of the adjustment member provides a mechanical advantage that causes the adjustment member to move axially along the main body; wherein the handle member can be moved axially relative to the main body of the delivery catheter between the distal end portion of the main body and the adjustment member by either axially sliding the handle member relative to the main body or by rotating the adjustment member relative to the main body when the adjustment member is in contact with the handle member, thereby axially moving the inner core relative to the outer sheath. - View Dependent Claims (20, 21, 22, 23)

24. A 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; an inner core configured to a support a stent thereon, the inner core being axially advanceable through the main body of the delivery catheter and the outer sheath; 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 overlaps the distal end portion of the second wire; wherein a bend formed in the first hollow release wire removably locks the distal end portion of the second wire to the first hollow release wire.
