  • Publication number: 20220370685
    Abstract: A seal member for use with a replacement heart valve implant may include a tubular polymeric seal element configured to be disposed on an outer surface of a replacement heart valve implant, the tubular polymeric seal element defining a central longitudinal axis; and a reinforcement strip fixedly attached to the tubular polymeric seal element proximate a first end of the tubular polymeric seal element, the reinforcement strip extending circumferentially around the central longitudinal axis. The reinforcement strip may include a radiopaque element extending circumferentially around the central longitudinal axis.

  • Patent number: 11147668
    Abstract: A delivery system for delivering an implantable heart valve includes an outer shaft and an inner shaft that is slidingly disposable within an outer shaft lumen, the inner shaft including a distal end region. A plurality of fingers extend distally relative to the distal end region of the inner shaft and are adapted to releasably engage an implantable heart valve. A plurality of looped sheathing aids extend distally from the distal region of an inner shaft lumen and are adapted to guide the implantable heart valve back into the outer shaft lumen when the implantable heart valve is pulled back into the outer shaft lumen. Each of the plurality of looped sheathing aids include a distal petal adapted to engage tissue adjacent a native valve annulus in order to limit distal advancement of the implantable heart valve during deployment of the implantable heart valve.

  • Publication number: 20180085214
    Abstract: A replacement heart valve implant may include an expandable anchor member actuatable between a delivery configuration and a deployed configuration, a plurality of locking mechanisms configured to maintain the expandable anchor member in the deployed configuration, one or more valve leaflets attached to each of the plurality of locking mechanisms, and at least one polymeric laminate corresponding to each locking mechanism, each of the at least one polymeric laminate sized and configured for mounting between a first portion of the corresponding locking mechanism and the expandable anchor member.

  • Patent number: 5385832
    Abstract: Substantially pure, pyrogen-free beta-1,3-glucan is produced by cultivating Euglena cells in a defined growth medium and under specified conditions that provide a cell mass comprising 70% to 90% beta-1,3-glucan on a dry weight basis, separating the cell mass from the supernatant, extracting the cell mass with methanol and chloroform, acid-washing the extracted cell mass, and washing the acid-treated material with water.
