Delivery apparatus for a prosthetic heart valve
Summary
USPTO granted patent US12588990B2 to Edwards Lifesciences Corporation on March 31, 2026, covering a delivery apparatus handle for prosthetic heart valves with an actuation knob featuring a toggle mechanism. The toggle allows operators to switch between moving multiple elements (for frame expansion/collapsing) and moving a single element (for locking/releasing the frame). The patent contains 18 claims.
What changed
USPTO granted patent US12588990B2 to Edwards Lifesciences Corporation for a prosthetic heart valve delivery apparatus. The invention comprises an actuation knob with a toggle mechanism that switches between two states: one enabling coordinated movement of multiple tubes attached to a heart valve frame for expansion or collapsing, and another enabling movement of a single element for locking or releasing the frame from the delivery apparatus. Inventors are Oren Cohen and Ofir Witzman, with filing date December 4, 2023 and application number 18528619.
This is a routine patent grant notification with no compliance obligations or deadlines for external parties.

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.
