Patent number: 10682217Abstract: Filtration systems with integrated filter element(s) forming portions of the wall of the filtration catheter are disclosed. The filtration catheters disclosed herein are designed to be used alone or in conjunction with another filter device to provide embolic protection of both carotid arteries. Occlusive element such as balloon is placed on the exterior of the filtration catheter to redirect blood flow in the vessels during the filtration process as well as to help anchor the filtration catheter inside the vessel. The integrated filter element(s) does not require collapsing thus significantly reduces the complexity of the filtration system retrieval process and the chances of releasing emboli back into the blood stream. The compact design of the filtration systems makes them particularly suitable for embolic protection during endovascular procedures on or close to the heart.Type: GrantFiled: September 14, 2017Date of Patent: June 16, 2020Assignee: Lumen Biomedical, Inc.Inventors: Kavitha Ganesan, Matthew F. Ogle

Publication number: 20200121334Abstract: Systems for less invasive medical procedures comprise a filter device mounted on an integrated guiding structure and an aspiration catheter. These components can be used together or separately, and the system can be used with other medical devices that are designed for less invasive procedures, such as procedures in a patient's vasculature. The catheter can have a radiopaque band that is held in place under metal wire embedded within the polymer forming the tube of the catheter. In some embodiments, the aspiration catheter has a small diameter distal portion that can access into small diameter vessels in which the distal portion has a smaller average diameter than the remaining tube of the catheter.Type: ApplicationFiled: November 30, 2019Publication date: April 23, 2020Inventors: Jason A. Galdonik, Edward J. Anderson, Kavitha Ganesan, Greg Boldenow, John Kirchgessner, Grazyna Wlodarski

Publication number: 20200046389Abstract: Clot engagement element comprising bundle of unwoven fibers can be assembled to form an acute stroke treatment device. The device has the capability of forming a three dimensional filtration matrix comprising effective pores with a distribution of sizes. The bundle of fiber design allows the device to be effectively delivered into circuitous cerebral arteries to remove clot that causes stroke. The fiber bundle based filtration matrix offers the advantages of conforming to the changing inner perimeter of a blood vessel during a clot removal process and thus the capability to effectively retain and remove a clot in the vessel. The filtration matrix offers the additional advantage to trap any break-off of the clot during the removal process. A plurality of fiber bundles can be combined to form an effective clot engagement element. Supplemental engagement structure as well as mechanical treatment structure can be integrated into the stroke treatment device.Type: ApplicationFiled: October 21, 2019Publication date: February 13, 2020Inventors: Jason A. Galdonik, Grazyna Wlodarski, John Kirschgessner, Kavitha Ganesan, Matthew F. Ogle

This document describes prosthetic heart valve designs and techniques to manage blood flow through the left ventricular outflow tract. For example, this document describes prosthetic heart valve designs and techniques that reduce or prevent obstructions of the left ventricular outflow tract that may otherwise result from systolic anterior motion of an anterior leaflet of the native mitral valve.Type: ApplicationFiled: October 1, 2019Publication date: February 6, 2020Inventors: Kavitha Ganesan, Ramji T. Venkatasubramanian, Cyril J. Schweich, Todd J. Mortier

These components can be used together or separately, and the system can be used with other medical devices that are designed for less invasive procedures, such as procedures in a patient's vasculature. The filter device can involve improved torque coupling with a torque coupler associated with a resilient member that correspondingly also provides increased flexibility relative to an overtube that forms a tube for the remaining portions of the device. An actuation tool for the filter device used a systematic loading procedure for proper loading of the corewire and overtube into the actuation tool. A fiber cartridge comprises fibers loaded as a bundle into the cartridge for delivery with the ends of the fibers respectively bonded to radiopaque markers that can be visualized to come together when the filter is properly deployed.Type: GrantFiled: May 27, 2011Date of Patent: August 28, 2018Assignee: Medtronic, Inc.Inventors: Jason A.
