Patent number: 11883043Abstract: The present disclosure includes a system for retrieving a blood clot in a blood vessel using a clot retrieval device having an expansile funnel that can engage with the blood clot. The present disclosure also includes a clot retrieval device having an expandable framework that can engage with the blood clot. The expansile funnel and expandable framework can expand from a collapsed delivery state to an expanded deployed state, increasing the cross-sectional area of the clot retrieval device engaging the blood clot. The increased cross-sectional area of the clot retrieval device can increase the suction force, providing effective removal of the clot from the patient.Type: GrantFiled: March 31, 2020Date of Patent: January 30, 2024Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Roberto Echarri, Dennis Fonseca

Publication number: 20230008234Abstract: A cerebral vessel access device having a base tube comprising an inner lumen, a shapeable element disposed to one side of the base tube, and an outer jacket covering the base tube and a portion of the shapable element. The shapable element can be configured to deflect from an axis line causing the base tube and outer jacket to deflect along with the shapable element.Type: ApplicationFiled: July 1, 2022Publication date: January 12, 2023Applicant: Neuravi LimitedInventors: David VALE, Brendan CASEY, Richard CONLON, Karl KEATING, Mahmood MIRZA, Kirk JOHNSON, Jorge POSADA, JR., Roberto ECHARRI, Andres RUIZ, Dennis FONSECA

Publication number: 20220280184Abstract: A clot retrieval cleaning instrument can have bristles, fluid sprays, or other techniques to liberate captured clot material from a clot retrieval device so that it can be reinserted into a patient's vasculature for successive capture attempts. The cleaning instrument can be conveniently integrated or connected to a hemo stasis valve assembly so that the cleaning function can be performed without completely removing the clot retrieval device from the delivery system. Aspiration can be applied to remove the freed thrombus material. The cleaning instrument can be removable from the delivery system to facilitate the instrument's washing or disposal.Type: ApplicationFiled: May 26, 2022Publication date: September 8, 2022Applicant: DePuy Synthes Products, Inc.Inventors: Roberto ECHARRI, Kirk JOHNSON

Patent number: 9669188Abstract: A noncircular inner lumen guiding catheter with assisted variable support has an inner wall defining a noncircular cross-sectional shaped lumen for use in delivery of multiple microcatheters or other devices for treatment of neurovascular defects, such as for treatment of aneurysms. The noncircular inner lumen guiding catheter with assisted variable support includes torque transmittal guidance walls that are flexible linearly but not circumferentially, and that are neither collapsible nor kinkable. The noncircular shaped cross-section of the inner lumen may extend along the entire length of the catheter or a portion thereof, including distal or proximal.Type: GrantFiled: April 17, 2014Date of Patent: June 6, 2017Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Roberto Echarri, Clifford D.

Publication number: 20150174378Abstract: A medical device formed of a coil with repeating loops, each loop forming a polygon and each successive loop being slightly rotated with respect to its adjacent loops to form a spiral configuration. The polygon in a preferred embodiment is a triangle, and the repeating triangular loop coil can be used as a guidewire in a stent delivering catheter. The guidewire can further include a stiff core wire that is disposed within the triangular loop coil, where the stiff core wire includes tapered sections that reduce the stiffness in the distal direction. The coil can include multiple sections of different loop shapes, including circular, to alter the stiffness of the guidewire to meet the needs of the application.Type: ApplicationFiled: March 9, 2015Publication date: June 25, 2015Inventor: Roberto ECHARRI
