Abstract
Delivery systems for expandable and stented implants include adjustable tensioning members that control the expansion of the implant along the length of the implant. The tensioning members are wound onto one or more rotors located on the distal segment of the delivery system, which are rotated to unwind the tensioning members and incrementally expand the implant. Positioning mechanisms are also provided to adjust the position and orientation of the implant during delivery.
Claims30
A system, comprising:
- a delivery catheter comprising:
- a proximal handle comprising a handle housing and an actuator;
- a catheter body coupled to the proximal handle, the catheter body comprising a distal section, a proximal section and a middle section therebetween, wherein the proximal section of the catheter body is coupled to the proximal handle and wherein the middle section of the catheter body and distal section of the catheter body extend distally from the proximal handle;
- a rotatable drive shaft coupled to the actuator and located in the catheter body;
- and
- a rotor disc attached to the rotatable drive shaft at the distal section of the catheter body, the rotor disc comprising a tension member attachment site and a tensioning member fixedly coupled to the tension member attachment site;
- and
- an expandable stent structure approximate the rotor disc,
- wherein:
- the tensioning member is releasably coupled to the expandable stent structure, and
- the tensioning member is at least partially wound about the rotor disc such that actuation of the rotor disc unwinds and extends the tensioning member from the delivery catheter to permit expansion of the expandable stent structure.

- wherein:
- the tensioning member is releasably coupleable to an expandable stent structure, and
- when releasably coupled to the expandable stent structure, the tensioning member is at least partially wound about the rotor disc such that actuation of the rotor disc unwinds and extends the tensioning member from the delivery catheter to permit expansion of the expandable stent structure.
