Patent number: 9511451Abstract: A system prevents oxidation of a laser cut workpiece by utilizing a laser source that utilizes laser source with an inert gas, such as argon or helium, rather than air or oxygen, to create the slots or kerfs which form the pattern cut into the workpiece. The system introduces oxygen gas through the workpiece as it is being laser cut to oxidize any slag or dross created during the laser cutting process. Oxygen or a mixture of oxygen with other gases cools the slag and the workpiece while at the same time oxidizing the slag to either completely burn or partial burn the slag before it strikes an exposed surface of the tubular member.Type: GrantFiled: July 2, 2014Date of Patent: December 6, 2016Assignee: Abbott Cardiovascular System Inc.Inventors: Jeffrey W. Baxter, David Mackiewicz

Patent number: 9126251Abstract: A method for making a device includes providing a tubular member which will be formed into the device, masking at least a portion of the inner surface of the tubular member with a removable sacrificial material, selectively removing a portion of the tubular member and sacrificial material using a laser device, and mechanically removing the sacrificial material from the inner surface of the tubular member. Ultrasonic energy could be applied to a workpiece which is being laser cut to prevent any generated slag from welding itself to an exposed surface of the workpiece. A compressed fluid or gas, such as air, could be used to clean the surface of the laser-cut workpiece to remove slag formation which adheres to the surface of the cut workpiece.Type: GrantFiled: December 7, 2012Date of Patent: September 8, 2015Assignee: Abbott Cardiovascular Systems Inc.Inventors: Michael R. Bialas, Robert P. Barbier, David Strauss, David Mackiewicz, Pius Kienzle, Mihaela Baldi

Patent number: 8779328Abstract: Methods for making devices include providing a tubular member to be formed into a device, placing a removable sacrificial block material in the lumen of the tubular member and laser cutting the tubular member. A tubular member made from nickel-titanium alloy can be tightly adhered to a sacrificial sleeve utilizing the phase changes associated with nickel-titanium. A mandrel which includes an enlarged diameter section causes the workpiece to expand slightly within its elastic deformation range to dislodge islands from the workpiece. Such a mandrel could be formed from a tubular member which has a central lumen that can be used to deliver a pressurized medium to “blast” islands from the workpiece.Type: GrantFiled: April 9, 2010Date of Patent: July 15, 2014Assignee: Abbott Cardiovascular Systems Inc.Inventors: Boris Anukhin, Larry Baughman, Pamela A.

Patent number: 8236039Abstract: The present invention is a luminal filter having wall contacts. The filter is formed to include: a plurality of filter elements interconnected so as to form a filter body shaped in a free recovery form and having a plurality of apertures disposed between and defined by the interconnected filter elements. The apertures are dimensioned so as to inhibit a thrombus of a selected size from passing through the apertures and being dimensioned so as to allow blood components smaller than the selected size to pass through the apertures. The polymeric wall contact is coupled to the filter and disposed on an external surface thereof. Optionally, a fastener can be used to secure the wall contact to the filter.Type: GrantFiled: December 18, 2008Date of Patent: August 7, 2012Assignee: Abbott LaboratoriesInventor: David Mackiewicz
