Patent number: 6793665Abstract: A vessel filter comprising first and second filtering portions and first and second anchoring portions. A transverse dimension of the first filtering portion in an expanded configuration is less than a transverse dimension of the anchoring portion in an expanded configuration, and a transverse dimension of the second filtering portion is less than a transverse dimension of the second anchoring portion. The first and second filtering portions are positioned closer to each other than the first and second anchoring portions, and the anchoring portions are formed on first and second opposite portions of the vessel filter. Preferably a sleeve is positioned between the first and second filter portions.Type: GrantFiled: June 18, 2001Date of Patent: September 21, 2004Assignee: Rex Medical, L.P.Inventors: James F. McGuckin, Jr., Richard T. Briganti

Patent number: 6783538Abstract: The present provides a removable vessel filter comprising a first and second filtering portion and a first and second anchoring portion, wherein a transverse dimension of the first filtering portion in an expanded configuration is less than a transverse dimension of the first anchoring portion in an expanded configuration, and a transverse dimension of the second filtering portion is less than a transverse dimension of the second anchoring portion. The first and second filtering portions are positioned closer to each other than the first and second anchoring portions, and the anchoring portions being formed on first and second opposite portions of the vessel filter. The vessel filter is removable from a vessel wall by engagement of either the first filtering portion or the second filtering portion.Type: GrantFiled: July 23, 2001Date of Patent: August 31, 2004Assignee: Rex Medical, L.PInventors: James E. McGuckin, Jr., Richard T. Briganti, Peter W. J. Hinchliffe

Patent number: 6695878Abstract: A vascular device movable from a collapsed insertion position having a first diameter to a first expanded position and further movable to a second expanded position having a second diameter larger than the first diameter. A plurality of vessel engaging members extend outwardly from the device for securing the internal wall of a vessel upon expansion of the device to the second expanded position. The vessel engaging members pull the internal wall of the vessel radially inwardly upon movement of the device from the second expanded position toward the first expanded position having a third diameter greater than the first diameter and less than the second diameter.Type: GrantFiled: June 8, 2001Date of Patent: February 24, 2004Assignee: Rex Medical, L.P.Inventors: James F. McGuckin, Jr., Richard T. Briganti

Publication number: 20040002681Abstract: A method of locating a vessel lumen to enable placement of a vascular hole closure device comprising the steps of providing a syringe containing a fluid therein, connecting the syringe to an elongated instrument, exerting a force on the syringe plunger as it is inserted through the tissue towards the vessel wall, and detecting movement of the syringe to eject the fluid to determine entry of the elongated instrument into the vessel lumen.Type: ApplicationFiled: June 27, 2003Publication date: January 1, 2004Applicant: Rex MedicalInventors: James F. McGuckin, Peter W.J. Hinchliffe, Richard T. Briganti, Walter H. Peters

Publication number: 20030144695Abstract: A device for closing an aperture in a vessel wall comprising an elongated member positionable inside the vessel against an internal opening of the aperture and having a dimension exceeding a dimension of the internal opening of the aperture to prevent egress of fluid through the aperture. At least two curved legs are coupled to the elongated member, curve in a direction substantially perpendicular to the longitudinal axis of the elongated member, and are positionable outside the vessel to help retain the elongated member in position the legs.Type: ApplicationFiled: January 16, 2003Publication date: July 31, 2003Inventors: James F. McGuckin, Richard T. Briganti
