DELIVERY DEVICE, SYSTEMS AND METHODS OF USE
First Claim
1. A delivery device comprising:
- an elongated flexible shaft having a proximal end, a distal end, and a main lumen therebetween; and
at least one flexible tubular guide extending through the main lumen, the at least one flexible tubular guide having a first end constrained within the shaft, at or near the distal end of the shaft and a second end constrained, at or near the proximal end of the shaft, the at least one flexible tubular guide unconstrained relative to the shaft in at least one location between the first and second ends so as to be laterally moveable within the main lumen, at least a portion of the at least one flexible tubular guide being both flexible and tubular.

Abstract
Devices, systems, methods and kits are provided for delivering interventional devices to a target location with a body. Such interventional devices particularly include fixation devices or any devices which approximate tissue, such as valve leaflets. The delivery devices and systems direct the interventional device to the target location through a minimally invasive approach, such as through the patient'"'"'s vasculature, and provide for manipulation of the interventional device at the target location, such as to approximate tissue. Optionally, the delivery devices and systems may provide for decoupling of the interventional device, allowing the interventional device to be left behind as an implant.

18. An endovascular heart valve repair device comprising:
-
an elongated flexible shaft having a proximal end, a distal end, and a main lumen therebetween, the elongated flexible shaft being adapted for positioning through a blood vessel into a chamber of the heart;
at least one flexible tubular guide extending from the proximal end to the distal end through the main lumen;

27. A system for approximating tissue at a treatment site comprising:
-
an elongated flexible shaft having a proximal end, a distal end, and a main lumen therebetween;
first and second movable elements extending through the main lumen from the proximal to the distal end and being movable relative to the shaft; and
