Patent number: 11833024Abstract: The embodiments described relate to retrieving temporary Inferior Vena Cava (IVC) filters and other endovascular implants or foreign bodies. Features are provided for effective actuation in closing an inner aperture of the embodiments.Type: GrantFiled: November 23, 2020Date of Patent: December 5, 2023Assignee: AVANTEC VASCULAR CORPORATIONInventors: Kathryn Stecco, Nicholas DeBeer, Karl Halden, Teresa Ruvalcaba, Frank Becking

Patent number: 11833025Abstract: After a prolonged period in the body, an IVC filter can be substantially absorbed by the body. When this occurs, it can be very difficult and/or dangerous for the patient if the IVC filter is forcibly removed. Thus, it is desirable to have systems and methods for safely abandoning the removal procedure of the IVC filter. Example embodiments of an apparatus for safely abandoning the removal procedure of the IVC filter can include: a sleeve having a lumen and a first hole on a wall of the sleeve; a shaft slidably disposed within the lumen of the sleeve; a flexible distal extension comprising a braid structure with a first opening; and a first lasso encircling a portion of the first opening of the braid.Type: GrantFiled: December 28, 2020Date of Patent: December 5, 2023Assignee: AVANTEC VASCULAR CORPORATIONInventor: Teresa Ruvalcaba

Publication number: 20220304835Abstract: An aneurysm embolization device can include a body having a single, continuous piece of material that is shape set into a plurality of distinct structural components. For example, the device can have an expandable component and an atraumatic tip portion extending therefrom. Further, the tip portion can be configured to enable the device to be implanted within the aneurysm while tending to mitigate risk of puncturing the aneurysm dome or otherwise assist in framing the aneurysm in advance of placement of additional embolic material.Type: ApplicationFiled: June 15, 2022Publication date: September 29, 2022Inventors: Teresa Ruvalcaba, Earl Bardsley, Richard Rhee

Patent number: 11051926Abstract: Funnel-trap type devices are described that are made of shape-set (e.g., heatset) braid for delivery and/or retrieval of Inferior Vena Cava (IVC) filters or other medical devices. Delivery and/or retrieval devices, kits in which they are included, methods of use and methods of manufacture are all contemplated. Additional forming tooling, methods and device embodiment shapes are described herein.Type: GrantFiled: June 13, 2018Date of Patent: July 6, 2021Assignee: AVANTEC VASCULAR CORPORATIONInventors: Frank Becking, Nicholas DeBeer, Karl Halden, Teresa Ruvalcaba

Patent number: 11013589Abstract: Methods and systems for retrieving temporary Inferior Vena Cava (IVC) filters, other medical implants, or foreign bodies are described. These methods may employ a locking sheath or a proximal-aperture capture feature for IVC filter (or other device) retrieval. One of the methods includes: passing an elongate member having a braided funnel-shaped distal extension through a sheath, where the braided funnel-shaped distal extension includes a distal bend to form a distal aperture and a flap that defines a proximal aperture; passing an end of the medical device through the distal aperture and then through the proximal aperture to capture the medical device; and covering the medical device with the sheath.Type: GrantFiled: March 15, 2018Date of Patent: May 25, 2021Assignee: AVANTEC VASCULAR CORPORATIONInventors: Frank Becking, Kathryn A.

Publication number: 20210085334Abstract: Disclosed are example embodiments of an endovascular coil having a twisted figure 8 shape. The endovascular coil includes: a first loop; a second loop; and an inflection region where a portion of the first loop transitions into a portion of the second loop. The second loop is rotated about an axis parallel to the longitudinal axis of the first loop to create the twisted figure 8 shape. The twist adds more randomness and variability to the filling behavior of the endovascular coil. The added randomness and variability enables the twisted figure 8 coil to better fill the void of irregular-shaped aneurysms than other conventional embolic coils.Type: ApplicationFiled: September 13, 2020Publication date: March 25, 2021Inventors: John Thao To, Ryan Masato Hoshino, Teresa Ruvalcaba
