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.
Claims45
A delivery system, comprising:
- a proximal handle comprising a handle housing and a first actuator;
- a catheter body coupled to the handle, the catheter body comprising a distal section, a proximal section and a middle section therebetween;
- a rotatable drive shaft coupled to the first actuator and located in the catheter body;
- a first stator housing attached to the catheter body, the first stator housing comprising an internal opening and an external opening;
- a first rotor attached to the rotatable drive shaft and located in the first stator housing, the first rotor comprising at least one tension line attachment site;
- a self-expanding implant, the implant comprising a contracted configuration and an expanded configuration;
- and a first tensioning member releasably coupled to the self-expanding implant and fixedly coupled to the attachment site of the first rotor and
- a movable sheath located over the catheter body.

A delivery system, comprising:
- a proximal handle comprising a handle housing and a first actuator;
- a catheter body coupled to the handle, comprising;
- a first rotatable drive shaft coupled to the first actuator and located in the catheter body, the first rotatable drive shaft comprising a first mechanical interfit interface at a distal end of the first rotatable drive shaft;
- and
- a first locking structure coupled to the catheter body;
- an implant delivery body, comprising:
- a first stator housing attached to the implant delivery body, the first stator housing comprising an internal opening and an external opening;
