Patent number: 11925337Abstract: Apparatus and methods for sealing a puncture through tissue includes an introducer sheath sized for introduction into a puncture, cartridge sized for insertion into the introducer carrying a sealant, and a locking element for coupling the introducer sheath to the cartridge. When the cartridge is advanced into the introducer sheath, the locking element couples the introducer sheath to the cartridge such that subsequent retraction of the cartridge causes the introducer sheath to retract, thereby deploying the sealant from the cartridge within the puncture beyond the introducer sheath.Type: GrantFiled: December 23, 2019Date of Patent: March 12, 2024Assignee: ACCESS CLOSURE, INC.Inventors: Celso J. Bagaoisan, Sieu Duong, Fred H. Co, Juan Domingo

Patent number: 11707266Abstract: An apparatus for sealing a puncture includes a cartridge, a pusher member, a sealant, and a tamping device on a proximal end of the cartridge. During use, the cartridge, sealant, and pusher member are advanced over a positioning member and into the puncture by advancing a cartridge hub carrying the tamping device. When further distal advancement of the cartridge is limited, the cartridge hub is further advanced, activating the tamping device, and causing the pusher member to advance relative to the sealant to compress the sealant within the puncture.Type: GrantFiled: September 15, 2020Date of Patent: July 25, 2023Assignee: ACCESS CLOSURE, INC.Inventors: Celso J. Bagaoisan, Juan Domingo, Sieu Duong

Patent number: 11707265Abstract: An apparatus for sealing a puncture includes a positioning member including a proximal end, a distal end sized for insertion into a puncture, an expandable element on the distal end, and a tension indicator on the proximal end. The tension indicator includes a distal housing portion fixed relative to the proximal end, and a proximal housing portion or handle movable proximally relative to the distal housing portion. The handle is biased towards the distal housing portion such that, when sufficient tensile force is applied between the expandable element and the handle, the handle moves away from the distal housing portion. During use, the distal end is introduced through a puncture into a vessel, the expandable element is expanded, and the positioning member is partially withdrawn until the expanded element contacts a wall of the vessel and the handle separates from the distal housing portion, indicating that sufficient tension is applied.Type: GrantFiled: March 23, 2020Date of Patent: July 25, 2023Assignee: ACCESS CLOSURE, INC.Inventors: Celso J.

Patent number: 10390847Abstract: An aspiration device can be used to aspirate an obstruction from a blood vessel. The aspiration device is configured to allow controlled one-handed aspiration yet maintain a syringe plunger feel of vacuum. The aspiration device also allows one-handed injection to empty the device when needed. Furthermore, mechanisms enable one-handed locking of a plunger position of the device to maintain vacuum when the user releases the device.Type: GrantFiled: June 20, 2017Date of Patent: August 27, 2019Assignee: Silk Road Medical, Inc.Inventors: Michi E.
