Patent number: 9271856Abstract: Heart valve delivery systems and methods of delivering and implanting heart valves using delivery catheters are disclosed. The delivery systems can include a handle assembly with a rotatable control knob and a catheter including an introducer shaft, an intermediate shaft extending from the handle assembly, an inner shaft extending from the handle assembly, and a capsule for containing a prosthesis. The distal end of the capsule can be connected to a distal end of the inner shaft, which can be moved in a distal direction by the rotatable control knob to deploy the prosthesis. By advancing the introducer through the deployed prosthesis and retracting the capsule to mate with the introducer, a smooth profile can be created for retraction of the system through the deployed prosthesis, minimizing hang-ups and snagging.Type: GrantFiled: July 25, 2012Date of Patent: March 1, 2016Assignee: Medtronic Vascular GalwayInventors: Niall Duffy, Ronan Rogers, John Gallagher, Gavin Kenny

Patent number: 9144493Abstract: The delivery systems disclosed herein can create simultaneous movement of an inner and an outer sheath of the delivery system. The delivery systems can generally include a handle assembly and a delivery catheter. In certain embodiments, the inner shaft and the outer sheath can be slidably controlled by a control element in the handle. The handle assembly can include a housing with a thumbwheel acting as the control element. In certain embodiments, movement of the inner shaft and the outer sheath can be caused via a gear-type system. In certain embodiments, the handle assembly can include a rotatable housing. A control element can rotate the housing, which can cause a first boss associated with the outer sheath and a second boss associated with the inner shaft to move in opposite directions.Type: GrantFiled: November 14, 2012Date of Patent: September 29, 2015Assignee: Medtronic Vascular Galway LimitedInventors: Damian Carr, Kate Corish, Niall Duffy, Ronan Rogers, Yossi Tuval, Frank White, Declan Costello, John Gallagher, James Kearns, Edmond Sheahan, Matthew Rust
