Patent number: 11576694Abstract: A device and a method for increasing or restoring a flow in a body lumen are provided. The device and the method may treat conditions related to a stroke, such as an ischemic stroke, by removing an occlusion from a blood vessel and/or reopen a blood vessel. The device may comprise a tubing compartment, a central wire, and an engaging compartment. The engaging compartment may comprise a distal engaging element and a proximal engaging element. A clot or occlusion present in the body lumen such as an artery may be engaged in and/or between the distal and proximal engaging elements. Further, the positions of one or both of the engaging elements and the distance therebetween can be adjusted to ensure the engagement of the clot or occlusion.Type: GrantFiled: November 24, 2020Date of Patent: February 14, 2023Assignee: Thrombx Medical, Inc.Inventors: Michael P.

Patent number: 9814465Abstract: A device for delivering an occlusive element includes an elongate pusher member having a lumen. A locking member is disposed within the lumen of the elongate pusher member. A moveable elongate releasing member is disposed within the lumen of the elongate pusher member. A filament is secured to the distal end of the elongate releasing member. The occlusive member is locked to the elongate releasing member when the filament passes through a securing member on the occlusive member and is pinched or wedged between the looking member and the elongate releasing member. The occlusive element is in an unlocked state when the elongate releasing member is retracted proximally relative to the elongate pusher member. The filament, along with the elongate releasing member, are retracted proximally until the filament is detached or uncoupled from the securing member of the occlusive member.Type: GrantFiled: September 16, 2014Date of Patent: November 14, 2017Assignee: Boston Scientific Scimed, Inc.Inventors: Thazin Win, Like Que, Esther Chang, Ann Huang
