Publication number: 20120095550Abstract: 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: August 11, 2011Publication date: April 19, 2012Inventor: John Gainor

Publication number: 20120065728Abstract: 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: ApplicationFiled: May 10, 2011Publication date: March 15, 2012Inventors: John Gainor, Gary A. Thill, Robert Foster Wilson, Christopher M. Banick

Publication number: 20080195123Abstract: The present invention provides a septal defect closure device (10) having a first occluding disk (30) having a first flexible membrane (32) attached to a first frame (34) and a second occluding disk (20) having a second flexible membrane (22) attached to a separate second frame (24). The first frame has at least two outwardly extending loops joined to one another by flexible joints. These loops are attached to the first membrane to define taut fabric petals when the first disk is in a deployed configuration. A central portion of the first membrane is joined to the central portion of the second membrane via a joining segment, which may comprise a conjoint disk. The flexible joints of the first frame are received within the joining segment. This septal defect closure device provides enhanced retrievability.Type: ApplicationFiled: April 25, 2008Publication date: August 14, 2008Applicant: EV3, INC.Inventors: John Gainor, Jeff Helgerson, Richard S.

Publication number: 20080082165Abstract: 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: September 28, 2007Publication date: April 3, 2008Inventors: Robert Foster Wilson, John Gainor

Publication number: 20060276874Abstract: 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: May 26, 2006Publication date: December 7, 2006Inventors: Robert Wilson, John Gainor

Patent number: 7033393Abstract: An occlusion device for occluding a defect in a spinal disc anulus, including a plate and a retention device. The plate defines an anulus contact face. The retention device extends from the contact face of the plate and defines an anulus engagement portion. The retention device is deflectable relative to the plate such that in a deployed state, the retention device biases the plate against material disposed between the contact face of the plate and the anulus engagement portion. Upon final deployment, the retention device bears against the exterior surface of the anulus, biasing the plate into contact with the interior surface of the anulus. In a preferred embodiment, the retention device includes a pair of L-shaped arms each extending in an opposing, angular fashion from the plate.Type: GrantFiled: April 30, 2003Date of Patent: April 25, 2006Assignee: Raymedica, Inc.Inventors: John Gainor, Britt K. Norton, Orson James May, Anthony C. Phillips

Publication number: 20040002763Abstract: An occlusion device for occluding a defect in a spinal disc anulus having interior and exterior surfaces, and defining an internal cavity. The occlusion device includes a first member, a second member, and a connector. The first member is configured for deployment within the internal cavity and placement against the interior surface of the anulus. The second member is configured for placement against the exterior surface of the anulus. Finally, the connector connects the first and second members and is preferably adapted to provide an adjustable spacing therebetween. With this construction, the device is configured such that upon final deployment, the first and second members are rigidly secured against the anulus, at opposite surfaces thereof, in a region of the defect via the connector.Type: ApplicationFiled: June 27, 2002Publication date: January 1, 2004Applicant: Raymedica, Inc.Inventors: Anthony C.
