The device includes an upper filter chamber and a lower filter chamber coupled to the upper filter chamber. The device further includes a coarse filter mesh disposed within the upper filter chamber, configured to capture the clot material from whole blood directed into the upper filter chamber, and a fine filter mesh disposed within the lower filter chamber, configured to filter the whole blood into filtered whole blood. The device further includes an inlet port fluidly coupled to the upper filter chamber, configured to accept the whole blood into the upper filter chamber. The device further includes an outlet port fluidly coupled to the lower filter chamber, configured to accept the filtered whole blood from the lower filter chamber and direct it to an external source.Type: ApplicationFiled: October 21, 2024Publication date: April 24, 2025Inventors: Greg Bak-Boychuk, Jake Le, Sanjay Shrivastava, Cheng Ian

Publication number: 20240227153Abstract: Disclosed is a foldable workbench (100) with a simple push and pull mechanism for opening and closing of legs without compromising on quick opening and folding performance. The leg opening and closing mechanism of workbench (100) is provided without rack and pinion gears, belt and pulley system or complex linkages with bearings, etc. A simple pulling and pushing action of a handle extends and retracts the first and second pair of legs (20A, 20B) to open and close.Type: ApplicationFiled: March 31, 2023Publication date: July 11, 2024Inventor: Sanjay Shrivastava

Publication number: 20230338048Abstract: Methods for restoring blood flow in occluded blood vessels using an apparatus having a self-expandable distal segment that is pre-formed to assume a superimposed structure in an unconstrained condition but can be made to take on a volume-reduced form making it possible to introduce it with a microcatheter and a push wire arranged at the proximal end, with the distal segment in its superimposed structure assuming the form of a longitudinally open tube and having a mesh structure of interconnected strings or filaments or struts. In a preferred embodiment, the distal segment has a tapering structure at its proximal end where the strings or filaments or struts converge at a connection point.Type: ApplicationFiled: November 16, 2022Publication date: October 26, 2023Inventors: Earl Howard Slee, Thomas Wilder, III, Thomas McCarthy, Mark Philip Ashby, Sanjay Shrivastava

Patent number: 11690741Abstract: Vascular remodeling devices can include a proximal section, an intermediate section, and a distal section. During deployment, the proximal section can expand from a compressed delivery state to an expanded state and anchor the device in an afferent vessel of a bifurcation. The distal section expands from the compressed delivery state to an expanded state that may be substantially planar, approximately semi-spherical, umbrella shaped, or reverse umbrella shaped. The distal section is positioned in a bifurcation junction across the neck of an aneurysm or within an aneurysm. The intermediate section allows perfusion to efferent vessels. Before or after the device is in position, embolic material may be used to treat the aneurysm. The distal section can act as a scaffolding to prevent herniation of the embolic material. The device can be used for clot retrieval with integral distal embolic protection.Type: GrantFiled: September 16, 2020Date of Patent: July 4, 2023Assignee: COVIDIEN LPInventors: Anh Cam, Michael Losordo, Jianlu Ma, Luong Nguyen, Sanjay Shrivastava, John Wainwright, Xiaoling Zhao

Publication number: 20230131648Abstract: A clot retrieval device featuring a capturing basket coupled to a delivery shaft. The capturing basket is deployable to the side of a clot in a blood vessel. The capturing basket is configured to allow for the clot to ingress into the capturing basket and surround at least a portion of the clot. The capturing basket can be torqued by torquing at the proximal end of the catheter resulting in the rotation of the capturing basket about its longitudinal axis.Type: ApplicationFiled: December 22, 2022Publication date: April 27, 2023Inventors: Sanjay Shrivastava, Gopan Patel

Publication number: 20220202430Abstract: A clot retrieval device is provided. The clot retrieval device includes a capturing basket having an opening at a proximal end where the capturing basket is deployable downstream from a clot in a blood vessel. The capturing basket is configured to surround a portion of the clot and the opening in the proximal end of the capturing basket is configured to reduce in size such that the capturing basket conforms around the portion of the clot and be retrieved after the capturing basket conforms around the portion of the clot.Type: ApplicationFiled: March 14, 2022Publication date: June 30, 2022Applicant: Innova Medical, Inc.Inventors: Sanjay Shrivastava, Jianlu Ma
