  • Publication number: 20240261539
    Abstract: A tubular support structure for use in an elongate intravascular medical device comprises an elongate tubular body, a patterned frame structure formed within the elongate tubular body, an inner lumen axially disposed within the elongate tubular body, and a first set of floating tabs axially spaced apart along the patterned frame structure. Each of the first set of floating tabs has a cantilevered end affixed to the patterned frame structure and a free end configured for translating relative to the patterned frame structure and then engaging the patterned frame structure as the tubular support structure is laterally deflected in a first bending direction.

  • Patent number: 11278707
    Abstract: A balloon catheter which allows for faster preparation and more effective purging of air within the catheter, while also providing a more space efficient design, wherein the balloon catheter includes a tubular outer member and a tubular inner member disposed in the lumen of the outer member such that the outer member and inner member define an annular fluid path between them. A balloon is secured to and circumferentially surrounds an outer surface of the distal portion of the outer member. A tubular seal is disposed circumferentially around the outer surface of the distal portion of the inner member. The inner member is movable longitudinally relative to the outer member from a non-sealing position in which the annular fluid path is open, and a sealing position in which the distal portion of the outer member contacts the seal thereby sealing the annular fluid path at the seal.

  • Patent number: 10314602
    Abstract: An embolectomy device includes a tubular body having a plurality of interconnected primary struts that define a plurality of openings when the tubular body is in a radially expanded deployed configuration, and a plurality of secondary struts connected to the primary struts that move from being aligned with the primary struts to a non-aligned configuration in which the secondary struts extend at least partially into and/or across the openings, to thereby ensnare or encapsulate a vascular obstruction within the primary and secondary struts after the tubular body is deployed proximate the obstruction and allowed to expand into or through the obstruction.

  • Patent number: 9692557
    Abstract: Apparatus and methods for administering treatment within a bodily duct of a patient. According to one implementation a treatment catheter having an expandable structure disposed at an end thereof is provided that includes an elongate hollow shaft having a one or more first through holes and one or more second through holes spaced axial apart, the one or more first through holes residing beneath the expandable structure. A sleeve positioned along an outer surface of the hollow shaft is moveable between first and second axial positions to respectively permit or inhibit the flow of a treatment agent through the one or more second through holes into the bodily duct. An elongate wire having a seal unit is positioned within an inner lumen of the hollow shaft.
