Publication number: 20220218459Abstract: A blood filter having a support structure and a filter structure. Various embodiments of the filtering assemblies may be utilized as a temporary implant or a permanent implant. The support structure, which serves as an anchor for the blood filter may define a larger porosity. The filter structure may define a smaller porosity, the smaller pores of which prevent emboli from passing therethrough. The support and filter structures may be made separately and assembled. In some embodiments, the filter structure actively slides on the support structure to accommodate the collapsing and deployment of the filter assembly. In some embodiments, a polymer film is selectively applied to the filter structure to provide a more uniform porosity over an outer bend radius of the filter structure. In some embodiments, the filter assembly is shaped to conform to the contours of the aortic arch while enabling self-cleaning of the filter structure.Type: ApplicationFiled: May 18, 2020Publication date: July 14, 2022Inventors: Vitali VERIN, Olivier COQUOZ, Alexandre ROMOSCANU, Duncan KEEBLE, Kent STALKER

Publication number: 20210393392Abstract: A blood filter device having occlusion-resistant characteristics. The occlusion-resistant characteristics decrease the likelihood of the filter being blocked by thrombi. The filter device includes at least one anchor portion for anchoring the filter device within an aortic branch artery, and a filter portion for filtering thrombi from the blood entering the artery. The filter portion includes an open channel at an open end that, in an implanted configuration, flares outward to increase the width of the filter portion. The open end may accommodate passage of surgical instruments into the artery and may enable blood flow to bypass the filter should the filter become heavily occluded.Type: ApplicationFiled: April 5, 2021Publication date: December 23, 2021Inventors: Vitali Verin, Olivier Coquoz

Patent number: 10966811Abstract: A blood filter device having occlusion-resistant characteristics. The occlusion-resistant characteristics decrease the likelihood of the filter being blocked by thrombi. The filter device includes at least one anchor portion for anchoring the filter device within one or more arteries, and a filter portion for filtering thrombi from the blood entering the artery. In some embodiments, an anchor portion is capped with a filter cap. In various embodiments, the filter cap is protrudes into the aorta to promote occlusion resistance. In one embodiment, the device can be modified in situ to re-establish normal blood flow through the artery in the unlikely case of thrombotic or other blockage of the filter. In some embodiments, a bypass opening or open channel defining an access port is provided to accommodate passage of surgical instruments into the artery and to enable blood flow to bypass the filter should the filter become heavily occluded.Type: GrantFiled: April 24, 2020Date of Patent: April 6, 2021Assignee: VeoSource SAInventors: Vitali Verin, Olivier Coquoz

Patent number: 7640053Abstract: The catheter is guided along a blood vessel of a patient by the bipolar electrode functioning as a mobile sensor on the catheter tip connected to the electronic unit to monitor the advance of the catheter and determine any modification of successive signals received from the bipolar electrode in order to detect any deviation of the catheter tip from the required path along the blood vessel and to deliver control signals comprising a GO signal, a STOP signal or an END signal to respectively enable, interrupt or terminate the advance of the catheter. The bipolar electrode moreover serves to verify the contact of the catheter tip with the wall of the heart cavity of the patient by creating impulses and detecting the appearance of corresponding induced signals on a surface cardiogram of the patient. The combination of the bipolar electrode on the catheter with the electronic unit provides a portable catheterization system particularly suitable for performing urgent cardiac catheterizations outside hospitals.Type: GrantFiled: June 26, 2002Date of Patent: December 29, 2009Assignee: Endosense S.A.Inventor: Vitali Verin

Patent number: 6616629Abstract: The balloon catheter comprises a catheter tube surrounded distally by an elongated inflatable balloon. Throughout the catheter tube is a longitudinal lumen for positioning a radioactive radiation emitter within the balloon. The catheter comprises a second lumen for directing inflation fluid into the balloon. Belt means creating a waist are mounted on the balloon to squeeze it down to nearly the diameter of the catheter thereby leaving a small passage for the inflation fluid. The belt means divide the balloon into sections to assure a close center fit of the catheter within the balloon.Type: GrantFiled: June 14, 1999Date of Patent: September 9, 2003Assignee: Schneider (Europe) A.G.Inventors: Vitali Verin, Youri Popowski

Patent number: 6258019Abstract: A prepared catheter for intraluminal treatment of a vessel section with ionizing radiation, which catheter has an elongate shaft with a proximal end and distal end as percutaneous transluminal access to the vessel section, an inflatable balloon at the distal end of the shaft, and inflation lumen which runs through the shaft and opens into the balloon, and a source of ionizing radiation which can be positioned in the balloon, and which catheter is filled with a gas for applying pressure to the balloon. In this way, only a comparatively small proportion of the ionizing radiation is absorbed and rendered ineffective as it passes through the gas, and the intended dose of radiation can be administered within a short treatment time. The inflation lumen preferably has, along the greater part of the length lying within the patient's body during treatment, a cross-sectional area having a value in mm2 not greater than the balloon in mm3 divided by 1200.Type: GrantFiled: September 8, 1999Date of Patent: July 10, 2001Assignee: SciMed Life Systems, Inc.Inventors: Vitali Verin, Youri Popowski, Michael Schwager, Cirillo Ghielmetti
