Publication number: 20150182360Abstract: A bioabsorbable polymeric stent with time dependent structure and properties and methods of treating a diseased blood vessel with the bioabsorable polymeric stent are disclosed. The structure and properties of the stent change with time and allow the vessel to be restored to a natural unstented state. The bioabsorbable stent loses mechanical integrity in a controlled manner due to modification of selected structural elements.Type: ApplicationFiled: March 12, 2015Publication date: July 2, 2015Inventors: Mikael Trollsas, Dariush Davalian, Michael Huy Ngo, Hao-Ming Hsiao, Boris Anukhin, Syed Hossainy, David Gale

Patent number: 8998945Abstract: An implantable lumen filter is described. The filter may include a body formed from an elongate member. The body may include loops encircling an axis extending along the length of the body. The body may be sized to be implanted into a body lumen. The body may be capable of transitioning from a collapsed state to a deployed state. The filter may include a first group of a plurality of members positioned around at least one loop of said body. At least a portion of the plurality of members may be oriented towards the axis. The plurality of members may be arranged to capture and/or lyse particulates of a selected size and/or to inhibit the particulates from passing through the body. Methods of making, deploying, and retrieving the same are described.Type: GrantFiled: December 16, 2009Date of Patent: April 7, 2015Assignee: Abbott Laboratories Vascular Enterprises LimitedInventors: Boris Anukhin, David Mackiewicz, Michael L.

Patent number: 8974514Abstract: An expandable stent is implanted in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The stent includes a plurality of rings connected by links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. The stent can be compressed or crimped onto a catheter to a very low profile since links are integrally formed from a portion of the struts forming the rings. The stent is constructed so that the cylindrical rings are very close together in order to provide maximum scaffolding, and if the stent has a drug coating, to provide a uniform drug delivery over the length of the stent. The connecting links are integrally formed from a portion of the struts forming the rings so that the links can have a maximum length thereby providing increased longitudinal flexibility of the stent.Type: GrantFiled: March 13, 2007Date of Patent: March 10, 2015Assignee: Abbott Cardiovascular Systems Inc.Inventors: Boris Anukhin, Hao-Ming Hsiao, Keif Fitzgerald

Publication number: 20140330363Abstract: A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold, after being deployed by the balloon, provides a crush recovery of about 90% after the diameter of the scaffold has been pinched or crushed by 50%. The scaffold also has a reduced crimped profile and a modification of the scaffold's ring structure at the crowns that contributes to the reduced crimped profile.Type: ApplicationFiled: July 3, 2014Publication date: November 6, 2014Inventors: Boris Anukhin, Michael H.

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.

Publication number: 20140090231Abstract: A method of manufacturing a stent is disclosed. The stent includes a minimum crimped diameter such that in the minimum crimped diameter, a pair of stent rings, between which marker support structures reside, do not make contact with the marker support structures. The crimped profile of the stent of the present invention can be as small as the crimped profile of a same stent but without the marker support structures.Type: ApplicationFiled: December 4, 2013Publication date: April 3, 2014Applicant: Abbott Cardiovascular Systems Inc.Inventors: Mikael Trollsas, Michael H.
