Patent number: 9439760Abstract: A stentless support structure capable of being at least partly assembled in situ. The support structure comprises a braided tube that is very flexible and, when elongated, becomes very long and very small in diameter, thereby being capable of placement within a small diameter catheter. The support structure is preferably constructed of one or more thin strands of a super-elastic or shape memory material such as Nitinol. When released from the catheter, the support structure folds itself into a longitudinally compact configuration. The support structure thus gains significant strength as the number of folds increase. This radial strength obviates the need for a support stent. The support structure may include attachment points for a prosthetic valve.Type: GrantFiled: March 2, 2015Date of Patent: September 13, 2016Assignee: HLT, Inc.Inventors: Gary A. Thill, Robert Foster Wilson, John P. Gainor, Christopher M. Banick

Publication number: 20160220358Abstract: An expandable delivery tool for aiding the deployment of a prosthesis device within a patient. The delivery tool has a generally elongated shape with a selectively expandable distal end region that flares outward in diameter. Once advanced percutaneously within a patient's vessel, the delivery device can help locate a target area, assist in deploying a prosthesis at a desired position and further expand the prosthesis after deployment.Type: ApplicationFiled: April 11, 2016Publication date: August 4, 2016Applicant: HLT, Inc.Inventors: Robert Foster Wilson, John Gainor

Publication number: 20160051363Abstract: An intravascular cuff acts as a lining between a native vessel and an intravascular prosthetic device. During deployment, the ends of the cuff curl back upon themselves and are capable of trapping native tissue, such as valve leaflet tissue, between the ends. The cuff creates a seal between the vessel and the prosthetic, thereby preventing leakage around the prosthetic. The cuff also traps any embolic material dislodged from the vessel during expansion of the prosthetic.Type: ApplicationFiled: October 30, 2015Publication date: February 25, 2016Applicant: HLT, INC.Inventors: Robert Foster Wilson, John P.

Publication number: 20140194980Abstract: A device and method for controlling commissural tip deflection of a prosthetic valve, thereby both preventing failure due to repeated movement and/or uneven loading of the commissural points and also improving coaptation of the valve leaflets, including connecting reinforcing material between the commissural points so a spring-like span is created across the points. The spanning material may be in the form of a ring that is lashed, sewn or otherwise connected to the commissural points. The reinforcing material may form curved segments between the commissural points that extend outwardly to form sinuses behind the leaflets of the prosthetic valve. The reinforcing material may also extend in an upstream direction to avoid interfering with blood flowing out of the prosthetic valve.Type: ApplicationFiled: March 10, 2014Publication date: July 10, 2014Applicant: HLT, Inc.Inventor: John Gainor
