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.
Core Innovation
The invention relates to a modular endoluminal catheter system that includes a main body and a delivery catheter sheath projecting distally from a distal end portion of the main body. A handle member is supported by the main body and is axially moveable along the main body by axially sliding the handle member relative to the main body, and the main body comprises a slot configured to receive a protruding portion of the handle member.
The system further provides an inner core that is axially advanceable through the main body, where the inner core is axially moveable by axially sliding the handle member relative to the main body. The inner core is selectively engageable by the handle member, coupling axial movement and engagement to control inner-core motion.
In some configurations, the handle member does not rotate relative to the main body, constraining the handle motion to axial sliding guided by the main-body slot. Additional structural features include external threads on the main body and selective engagement structures for engaging and releasing an inner core, and stent traction-support features are described as tabs or beads on a core wire for endoluminal stent or stent graft positioning.
Claims Coverage
The independent claims cover delivery catheter systems with a main body, an axially movable handle, and an axially advanceable inner core. Four independent claims are present, each focused on axial coupling, selective engagement, and relative rotation relationships.
Non-rotational axial sliding handle with main-body slot
A main body comprising a slot configured to receive a protruding portion of a handle member, where the handle member is axially moveable along the main body by axially sliding the handle member relative to the main body.
Axial advanceable inner core selectively engageable by axially sliding handle
An inner core axially advanceable through the main body, where the handle member is axially moveable along the main body, the inner core is axially moveable by axially sliding the handle member relative to the main body, and the inner core is selectively engageable by the handle member.
Axially advanceable inner core with inner core rotatable relative to handle
An inner core axially advanceable through the main body, where the inner core is axially moveable by axially sliding the handle member relative to the main body and the inner core is rotatable relative to the handle member.
Axially sliding handle to move inner core while handle does not rotate
An inner core axially advanceable through the main body and a handle member axially moveable along the main body, where the inner core is axially moveable by axially sliding the handle member relative to the main body and the handle member does not rotate relative to the main body.
Across the independent claims, the inventive core is the axial translation of handle motion into inner-core axial movement via sliding relative to a main body, combined with selective engagement and controlled relative rotation relationships.
