Publication number: 20220054150Abstract: A distal aspiration catheter comprises catheter body having a central lumen and at least one luminal channel. An aspiration source is configured to attach to a proximal end/luer hub of the central lumen. Each luminal channel includes one mandrel and a distal portion of the mandrel extends into a distal portion in the central lumen. When the aspiration source is activated, a clot/emboli lodged in a blood vessel is partially ingested into the distal portion of the central lumen. The distal portion of the mandrel can move into the partially ingested clot to induce clot fatigue. The fatigued clot can be removed completely by a single pass of the distal aspiration catheter.Type: ApplicationFiled: August 20, 2021Publication date: February 24, 2022Applicant: MicroVention, Inc.Inventors: Ronak Dholakia, Hussain Rangwala

Publication number: 20210205075Abstract: A transcatheter valve prosthesis includes an expandable tubular stent, a prosthetic valve within the stent, and an anti-paravalvular leakage component coupled to and encircling the tubular stent. The anti-paravalvular leakage component includes a radially-compressible annular scaffold, which is a sinusoidal patterned ring of self-expanding material, and an impermeable membrane extending over the annular scaffold. The anti-paravalvular leakage component has an expanded configuration in which at least segments of the annular scaffold curve radially away from the tubular stent. Alternatively, the anti-paravalvular leakage component includes a plurality of self-expanding segments and an annular sealing element coupled to inner surfaces of the segments. The anti-paravalvular leakage component has an expanded configuration in which the segments curve radially away from the tubular stent and the annular sealing element is positioned between an outer surface of the tubular stent and inner surfaces of the segments.Type: ApplicationFiled: March 24, 2021Publication date: July 8, 2021Inventors: Carol EBERHARDT, Gopikrishnan SOUNDARARAJAN, Kenny DANG, Hussain RANGWALA, Mark TORRIANNI, Eric RICHARDSON, Kshitija GARDE

Patent number: 9308569Abstract: A device for crimping an expandable medical device and loading the expandable medical device into a delivery system includes an actuator, a compression assembly, and a pusher. The compression assembly is disposed in a compression chamber of the actuator and includes a plurality of compression elements coupled to each other to form a central cavity. The compression elements are coupled to the actuator such that rotation of the actuator causes the compression elements to rotate such that the central cavity radially compresses from an expanded configuration to a compressed configuration. The pusher includes a pusher rod and is configured to translate relative to the actuator towards the compression chamber when the cavity is in the compressed configuration such that the pusher rod may enter the cavity and push the medical device out of the cavity into delivery system.Type: GrantFiled: February 1, 2013Date of Patent: April 12, 2016Assignee: Medtronic, Inc.Inventors: Gopikrishnan Soundararajan, Christopher Webster, Kenny Dang, Hussain Rangwala
