Patent number: 11931277Abstract: Implant engagement mechanisms are disclosed for maintaining engagement with a stent until it has been fully deployed and expanded from a catheter or sheath. The apparatus, method and system involving these engagement mechanisms allow a physician to withdraw or retract a sheath prior to full deployment, thereby allowing for redeployment of the stent at a more desirable position.Type: GrantFiled: April 2, 2021Date of Patent: March 19, 2024Assignee: MicroVention, Inc.Inventors: Ponaka Pung, Tai D. Tieu, Ross Soltanian, Helen Nguyen, Oanh Nguyen, Britney Ngo
