Patent number: 11517727Abstract: An apparatus for performing a medical procedure and, in particular, an aortic valvuloplasty, in a vessel for transmitting a flow of fluid. The apparatus includes an inflatable perfusion balloon including an internal passage for permitting the fluid flow in the vessel while the perfusion balloon is in an inflated condition, the balloon including a plurality of cells in a single cross section and a covering for at least partially covering the cells. A valve associated with the balloon controls the fluid flow within the passage, the valve being arranged external to the passage. The valve may form a tubular extension of the covering, or may be separate from the covering, and may comprise flaps. A spiral covering may also form the valve.Type: GrantFiled: March 12, 2020Date of Patent: December 6, 2022Assignee: C.R. BARD, INC.Inventors: Garrett Gomes, Anant Hegde, Jonathan Kurniawan, Andrew Moll, Cameron Moore, Samuel Radochonski

Publication number: 20210001094Abstract: A fiber-reinforced device, such as an inflatable medical balloon, includes a cylindrical central portion. The balloon includes first and second tapered portions connected to the cylindrical central portion along a central longitudinal axis extending from a first end of the balloon to a second end of the balloon. In one embodiment, the balloon includes a single continuous fiber running substantially parallel to the longitudinal axis along the central portion, and having a plurality of turnaround points in each of the first and second tapered portions. The single continuous fiber does not extend along or around a reduced diameter portion, or neck, connected to each of the tapered portions, and thus may remain continuous even after the necks are trimmed away to connect the fiber-reinforced balloon to a catheter shaft.Type: ApplicationFiled: March 9, 2018Publication date: January 7, 2021Inventors: Justin Hall, Corey E.

Patent number: 9574742Abstract: A surgical clip for illuminating tissue in a surgical field has first and second elongate arms and a connector joining the arms together. The arms are biased to expand laterally outward into an expanded configuration in which the arms engage the tissue in the surgical field with enough force to seat the clip without retracting the tissue. A waveguide illuminator is coupled to the first arm, and has a light input portion, a light output portion, and a light conducting portion extending between the light input portion and the light output portion. Light passes through the waveguide illuminator by total internal reflection, and the waveguide illuminator directs light to the tissue. Methods of using the illuminated clip are also disclosed.Type: GrantFiled: October 30, 2014Date of Patent: February 21, 2017Assignee: Invuity, Inc.Inventors: Alex Vayser, Anant Hegde, Douglas Rimer
