Abstract
In one embodiment, a delivery apparatus handle, such as for a mechanical heart valve frame can comprise an actuation knob with a toggle mechanism that can toggle the actuation knob from a first state in which the actuation knob is operable to cause the linear or rotational movement of multiple elements or sets of elements, such as tubes that are attached to, e.g., a mechanical heart valve frame to cause expansion or collapsing of the frame, to a second state in which only a single element or set of elements is moved, allowing for additional operations, such as, e.g., locking the frame and/or releasing it from the delivery apparatus.
Claims1
A delivery apparatus for implanting a medical device in a patient's body comprising:
- a handle;
- at least a first element, a second element, and a third element extending from the handle;
- an actuation knob configured to actuate at least one of the elements;
- a toggle configured to toggle the actuation knob between a first state and a second state, wherein when the actuation knob is in the first state, rotation of the actuation knob moves the first and second elements axially relative to the third element, and wherein when the actuation knob is in the second state, rotation of the actuation knob moves the first element axially relative to the second and third elements.
