Patent number: 8308753Abstract: A locking component for locking a medical device onto a guide wire. Such medical devices include, for example, an embolic filter assembly used to capture embolic material that may be created and released into a patient's vasculature during a stenting or angioplasty procedure. The embolic filter assembly tracks along the guide wire, and is delivered to a treatment site where it is locked in place and deployed. The locking component enables the filter assembly to lock onto any standard guide wire, and does not require a modified guide wire that has a specially-designed fitting or stop to accomplish the locking function.Type: GrantFiled: February 25, 2010Date of Patent: November 13, 2012Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Douglas H.

Patent number: 6726546Abstract: A method and apparatus for deburring nonmetallic machined workpieces. A deburring material of sufficient hardness to debur nonmetallic workpieces without causing scarring thereto is rubbed against a workpiece to effect deburring. The deburring material has a durometer hardness and consequently a coefficient of friction whereby frictional engagement of a burr with the deburring material is stronger than the attachment of the burr to the workpiece and therefore the burr is removed as the deburring material is actuated and brought into contact with the burr. The deburring material can be, e.g., polyisoprene and may be mechanically actuated or actuated by hand.Type: GrantFiled: January 9, 2003Date of Patent: April 27, 2004Assignee: Zimmer Technology, Inc.Inventors: David A.
