  • Publication number: 20210220607
    Abstract: Disclosed is an intraluminal catheter that includes a flexible elongate shaft configured to be positioned within a body lumen of a patient, and an intraluminal sensor disposed at the distal portion of the shaft that is configured to sense a characteristic within the body lumen. The shaft further comprises a plurality of wires disposed around a lumen, wherein the wires are helically twisted. The wires can be helically twisted in a single direction to form a cylindrical shape. This helical structure is configured to stiffen the flexible elongate shaft for movement into an obstruction within the body lumen without kinking.

  • Patent number: 8376989
    Abstract: A syringe includes a first fluid conduit and a second fluid conduit. The first fluid conduit includes two chambers for accommodating two substances of a plurality of substances. The second fluid conduit is disposed adjacent the first fluid conduit and has a chamber for accommodating one substance of the plurality of substances. The syringe may include a third fluid conduit. Each substance is intermixable to form a discharge material upon advancement of a plunger operably associated with each fluid conduit. The discharge material is defined by the intermixed composition of predetermined volumes of the substances the fluid conduits. The discharge material may be a hydrogel. A connecting tip may be operably associated with each fluid conduit. A syringe may include an end cap disposed on the end of each of the fluid conduits. The end cap may have a venting feature for enabling gas venting while preventing discharge until desired.
