Patent number: 10245419Abstract: In one embodiment, a balloon catheter is provided for use during annuloplasty. Preferably, the balloon includes a distal, noncompliant portion and a proximal semi-compliant portion which allows for sequential inflation, reliable positioning, and compliance measurement.Type: GrantFiled: January 22, 2016Date of Patent: April 2, 2019Assignee: InterValve Medical, Inc.Inventors: William J. Drasler, Wesley R. Pedersen, Mark Ungs

Patent number: 10220192Abstract: A bulbous valvuloplasty balloon is described that maintains its bulbous shape in its final deployed configuration along with the method of use for post dilation of a TAVR device. The bulbous balloon has two larger diameter bulb segments located on each side of a smaller diameter waist and can be used to post dilate a TAVR device that has been implanted at the site of a stenotic aortic valve. The post dilation causes deformation of the underlying tissues residing outside of the TARV stent structure.Type: GrantFiled: April 9, 2015Date of Patent: March 5, 2019Assignee: InterValve Medical, Inc.Inventors: William J. Drasler, Mark Ungs, Wesley R. Pedersen, Scott R. Schewe, Richard C. Kravik, Michael Scott Allen

Patent number: 9909358Abstract: An example of a vertically operating door includes a flexible panel comprising two pliable sheets of material with a plurality of pads or mats of thermal insulation between the two sheets. In some examples, a plurality of horizontally elongate baffles made of pliable strips of material are installed between the two sheets. The baffles effectively divide one large interior volume between the sheets into more manageable smaller volumes or chambers. The baffles restrict the air between the sheets from being forced to the bottom of the panel as the panel ascends and bends across an overhead roller. Without the baffles and smaller chambers, the panel sheets in the area near the bottom of the panel would tend to bulge outward as the door opens.Type: GrantFiled: July 26, 2010Date of Patent: March 6, 2018Assignee: RITE-HITE HOLDING CORPORATIONInventors: Mark Ungs, Glenn R. Manich

Patent number: 9511209Abstract: A measuring balloon has an inner bulbous balloon formed from a non-compliant or semi-compliant material and has a central smaller diameter inner waist and two larger diameter bulbs on each side of the inner waist. A compliant outer waist bladder is located on the outside of the inner bulbous balloon adjacent to the inner waist and is inflated via a separate inflation lumen. The inner balloon is inflated at a higher pressure to dilate stenotic aortic valve leaflets, and provide alignment and positioning of the measuring balloon across the aortic annulus. The bladder waist is inflated to a lower pressure to make contact with the aortic valve annulus. Marker bands positioned on the outside of the measuring balloon provide determination of annulus diameter and ovality.Type: GrantFiled: August 5, 2014Date of Patent: December 6, 2016Assignee: InterValve, Inc.Inventors: William J. Drasler, Mark Ungs, Wesley R. Pedersen

Patent number: 9504807Abstract: A valvuloplasty catheter has a dog-bone shaped balloon with semi-compliant smaller diameter waist and non-compliant larger diameter bulbous end regions. The balloon centers across the valve with the waist adjacent to the annulus. One bulbous region serves to hyperextend the valve leaflets and the other assists in stabilizing the balloon position to reduce migration. The semi-compliant waist increases in diameter as fluid enters the balloon until it comes into contact with the valve annulus. The pressure within the balloon per unit of volume delivery has a greater slope after contact with the annulus than before resulting in a change in slope for the pressure versus volume curve. The diameter of the balloon and annulus are determined at this inflection point when the balloon contacts the annulus.Type: GrantFiled: November 7, 2014Date of Patent: November 29, 2016Assignee: InterValve, Inc.Inventors: William Drasler, Wes Pedersen, Mark Ungs

Patent number: 9498151Abstract: A balloon catheter is used for dilating tubular members of the body such as dilating stenotic aortic valve leaflets found in the aortic root, and measuring the shape and dimensions of the annulus. The balloon has two larger diameter bulbous regions; one is positioned in the left ventricular outflow tract (LVOT) and the other in the aortic sinus; a smaller diameter waist region is positioned across the aortic annulus. During inflation of the balloon, the balloon waist expands in diameter until it comes into contact with the aortic annulus. The balloon pressure and inflation volume is monitored during inflation so that an inflection point in the dP/dV curve is seen at the point of contact of the waist with the annulus. Radiopaque rings and/or marker bands in the device allow the size and orientation of the elliptical annulus to be calculated.Type: GrantFiled: November 12, 2015Date of Patent: November 22, 2016Assignee: InterValve, Inc.Inventors: William J.
