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. Gainor

Patent number: 9168132Abstract: 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: May 15, 2013Date of Patent: October 27, 2015Assignee: HLT, Inc.Inventors: Gary A. Thill, Robert Foster Wilson, John P. Gainor, Christopher M. Banick

Publication number: 20150119853Abstract: A method of controlling and changing the shape of a catheter in situ that includes the use of two nested catheters. The catheters have two different shapes that may add, cancel, or override each other when one catheter is placed within the other. The shape may be changed by advancing or rotating one catheter relative to the other catheter.Type: ApplicationFiled: October 29, 2014Publication date: April 30, 2015Inventors: John P.

Publication number: 20150105729Abstract: A catheter with a spring tip that facilitates atraumatic initial placement and also continues to protect tissue contacted by the catheter device subsequent to the initial placement. The spring tip is shock-absorbing and axially compliant and allows enhanced use of various devices in conjunction with the tip such as bioptomes, electrodes, needles, flushing catheters, delivery catheters, and the like. The atraumatic shock-absorbing tip could include conductive or non-conductive materials.Type: ApplicationFiled: October 16, 2014Publication date: April 16, 2015Inventors: Uma S. Valeti, Robert F. Wilson, John P. Gainor

Publication number: 20090131978Abstract: A release assembly is provided to aid the reversible and repositionable deployment of a defect occluder. The release assembly includes an occluder tether having a distal portion comprising at least one suture loop, and a snare structure having a distal portion comprising a snare element. The at least one suture loop is receivable through at least a portion of the defect occluder, and reversibly looped over an anchor element so as to permit reversible collapse the defect occluder for selective ingress and egress from a delivery catheter. The snare element is reversibly engageable with the anchor element so as to reversibly retain the at least one suture loop upon the anchor element, and thereby hold the defect occluder in a posture for reversible free-floating tethered deployment in a defect while being observable in a final position prior to release.Type: ApplicationFiled: January 20, 2009Publication date: May 21, 2009Inventors: John P. Gainor, Brian L. Dukart, Darren L. Wegner
