Publication number: 20230157714Abstract: 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: January 23, 2023Publication date: May 25, 2023Inventors: Jason A. Galdonik, Grazyna Wlodarski, John Kirschgessner, Kavitha Ganesan, Matthew F. Ogle

Patent number: 10952757Abstract: 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: GrantFiled: June 27, 2018Date of Patent: March 23, 2021Assignee: Medtronic, Inc.Inventors: Jason A. Galdonik, Edward J. Anderson, Kavitha Ganesan, Greg Boldenow, John Kirchgessner, Grazyna Wlodarski

Publication number: 20200315678Abstract: Apparatus and methods for treatment of a bone. The apparatus may include a mesh anchoring substrate extending longitudinally between a base and a hub. The base may have a base first end adjacent the mesh, a base second end opposite the base first end, and a cannula extending through the base. The apparatus may include a support. The support may include an elongated body extending between an end of the support and a flange. The end of the support may be configured to be removably coupled to a coupling mechanism in the hub. The flange may be configured for being seated outside the base against the base second end. A maximum circumference of the elongated body may be not greater than a cannula circumference.Type: ApplicationFiled: January 9, 2020Publication date: October 8, 2020Inventors: Michael Charles Mazzio, Jeffrey Lincoln Carver, Grazyna Wlodarski, Eric Fulkerson, Frank Liporace, Michael Morwood, Anjan Shah, Roy W.

Patent number: 10058339Abstract: 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 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.
