Publication number: 20160220265Abstract: A device capable of capturing and facilitating the removal of a solid obstruction in a vessel or tube, such as a thrombus in blood vessels (or stones in biliary or urinary ducts, or foreign bodies) uses a soft coil mesh with the aid of a pull wire or string to engage the surface of a thrombus, and remove the captured thrombus. The soft coil mesh is formed by an elongated microcoil element that forms the helical elements of a macrocoil element. The microcoil element provides a relatively elastic effect to the helical elements forming the macrocoil and allows for control of gripping forces on the thrombus while reducing non-rigid contact of the device with arterial walls.Type: ApplicationFiled: April 8, 2016Publication date: August 4, 2016Inventors: James Pokorney, Stephanos Finitsis, John Kucharczyk

Patent number: 8603122Abstract: A device capable of capturing and facilitating the removal of a thrombus in blood vessels (or stones in biliary or urinary ducts, or foreign bodies) uses a soft coil mesh with the aid of a pull wire or string to engage the surface of a thrombus, and remove the captured thrombus. The soft coil mesh is formed by an elongated microcoil element that forms the helical elements of a macrocoil element. The microcoil element provides a relatively elastic effect to the helical elements forming the macrocoil and allows for control of gripping forces on the thrombus while reducing non-rigid contact of the device with arterial walls. The use of multiple coil mesh elements, delivered through a single lumen or multiple lumens, preferably with separate control of at least one end of each coil, provides a firm grasp on a distal side of a thrombus, assisting in non-disruptive or minimally disrupted removal of the thrombus upon withdrawal of the device.Type: GrantFiled: October 12, 2007Date of Patent: December 10, 2013Assignee: Nexgen Medical Systems, IncorporatedInventors: James L. Pokorney, Stephanos Finitsis, John Kucharczyk

Patent number: 8449566Abstract: A device captures and assists in the removal of a thrombus in arteries, even in small arteries. The device uses a soft coil mesh to engage the surface of a thrombus, and a guidewire is used to retract the soft coil mesh with the captured thrombus. The soft coil is formed by an elongated microcoil element that forms the helical elements of a macrocoil element. The microcoil element provides a relatively elastic effect to the helical element forming the macrocoil and allows for control of gripping forces on the thrombus while reducing non-rigid contact of the device with arterial walls.Type: GrantFiled: June 2, 2011Date of Patent: May 28, 2013Assignee: Nexgen Medical Systems, Inc.Inventor: Stephanos Finitsis
