  • Deployment handle for delivery of implants
    Patent number: 11957609
    Abstract: A delivery device for controllably delivering multiple implants (e.g., intravascular implants) is described herein. The delivery device may include a lockout mechanism to prevent against inadvertent implant deployment prior to initial use. The delivery device may also include a re-sheath mechanism to allow for re-sheathing of an inner core assembly prior to removal of the delivery device from an initial deployment site. The delivery device may also further include a mechanism configured to prevent against re-sheathing of a partially-deployed implant.

  • INTRAVASCULAR IMPLANT
    Publication number: 20220241098
    Abstract: An intravascular implant can include a pair of inner rings comprising a distal inner ring and a proximal inner ring. A plurality of inner bridges can extend between opposing adjacent apices of the distal and proximal inner rings. Each of the plurality of inner bridges can form an eyelet. The implant can include a pair of outer rings comprising a distal outer ring and a proximal outer ring. The distal and proximal outer rings that can each be formed by a plurality of struts connected by apices formed in a zig-zag pattern. A plurality of outer bridge members can include a plurality of outer bridge members that extend between opposing adjacent apices of the distal outer ring and distal inner ring and outer bridge members that extend between opposing adjacent apices of the proximal outer ring and proximal inner ring.
