Patent number: 10541938Abstract: An apparatus in one embodiment comprises at least one processing device having a processor coupled to a memory. The one or more processing devices are operative to configure a plurality of distributed processing nodes to communicate over a network, to obtain metadata characterizing data locally accessible in respective data zones of respective ones of the distributed processing nodes, and to populate catalog instances of a distributed catalog service for respective ones of the data zones utilizing the obtained metadata. Distributed data analytics are performed in the distributed processing nodes utilizing the populated catalog instances of the distributed catalog service and the locally accessible data of the respective data zones. The metadata characterizing the locally accessible data is illustratively obtained in a metadata repository from at least one of a master data management platform and a governance, risk and compliance platform.Type: GrantFiled: February 1, 2018Date of Patent: January 21, 2020Assignee: EMC IP Holding Company LLCInventors: Hans Timmerman, Patricia Gomes Soares Florissi

Publication number: 20160296317Abstract: A stent used in reducing a diameter of a transjugular intrahepatic portosystemic shunt (TIPS) for secondary restriction of flow through a TIPS tract is disclosed. In one example approach, a reducing stent comprises a tube-shaped framework with a tubular material affixed around an outer surface of the framework and extending through the interior of the framework to define a reducing passage in the interior of the framework. In another example approach, a transjugular intrahepatic portosystemic shunt system including a transjugular intrahepatic portosystemic shunt and a reducing stent mounted within an interior of the transjugular intrahepatic portosystemic shunt is disclosed.Type: ApplicationFiled: April 7, 2016Publication date: October 13, 2016Applicant: OREGON HEALTH & SCIENCE UNIVERSITYInventors: Hans Timmermans, John Kaufman

Patent number: 7608100Abstract: An intraluminal graft assembly is provided. In one embodiment, the assembly comprises a support frame having first, radially smaller and second, radially larger configurations. A graft is attached to the support frame at one end by connectors and is not connected to the other end. The graft extends along only a fractional length of the support frame when in the first configuration, and substantially along the entire length of the support frame when in the second configuration. A vessel repair system is also provided. In the system, a driving member is positioned to force the support frame from the first configuration to the second configuration.Type: GrantFiled: February 11, 2005Date of Patent: October 27, 2009Assignee: Cook IncorporatedInventors: Thomas A. Osborne, Hans A. Timmerman

Patent number: 5800456Abstract: A self-expanding endovascular stent formed of stainless steel wire which is bent into an elongated zigzag pattern. The zigzag pattern has a plurality of substantially straight wire sections of various lengths separating a plurality of bends. The zigzag pattern is helically wound about a central axis to define a tubular shape such that a majority of the bends are disposed in a helix. Adjacent bends in the helix are interconnected with a filament. The stent is capable of being radially compressed such that the straight wire sections and the bends are tightly packed around a central axis. The stent resiliently self-expands to assume a tubular shape when released from the compressed state. Depending on the pattern of the lengths of the straight wire sections in the zigzag pattern, the final tubular shape can be made irregular to match a patient's vascular system. In other words, the diameter of the tube which is defined by the stent can be made to vary along the length of the stent.Type: GrantFiled: June 13, 1997Date of Patent: September 1, 1998Assignee: Cook IncorporatedInventors: Munehiro Maeda, Hans A.

Patent number: 5690656Abstract: A method and apparatus for creating abdominal visceral anastomoses. A first magnet is placed within a first viscera and a second, larger magnet is placed within a second viscera. The magnets each have a raised rim around their perimeters. The two magnets couple to each other by virtue of their mutual attraction, thereby capturing a portion of the intervening visceral walls between them. The coupling of the magnets is automatically self-centering, as the smaller magnet is forced to rest within the raised rim of the larger magnet. Additionally, the raised rim of the smaller magnet acts as a fine cutting edge in order to accelerate the process of ischemic necrosis of the tissue captured between the two magnets, thereby forming the anastomosis. Use of the present invention avoids the need for general anasthesia and a laparotic incision, resulting in fewer surgical and post-surgical complications.Type: GrantFiled: June 27, 1995Date of Patent: November 25, 1997Assignee: Cook IncorporatedInventors: Constantin Cope, Hans A.

Patent number: 5183085Abstract: A method is disclosed for compressing a helically coiled stent by folding coils about a first plane and a second plane, each plane containing the longitudinal axis of the stent and the first plane being normal to the second plane, and maintaining separation between individual coils of the stent while folding. Apparatus for performing the compression includes a first pair of combs that engage the coils of the stent at diametrically opposed sides at points lying on a first plane that extends through the longitudinal axis of the stent. A second pair of combs engage the coils at diametrically opposed sides at points lying on a second plane that also extends through the stent longitudinal axis but is normal to the first plane. The first pair of combs are mounted on a track that permits them to be moved relative to the second pair of combs along the stent longitudinal axis.Type: GrantFiled: September 27, 1991Date of Patent: February 2, 1993Inventor: Hans Timmermans

Patent number: 4581025Abstract: A sheath comprising a tubular structure formed of a flexible material which is compatible for insertion within the body and having proximal and distal ends. In one embodiment, the tubular structure includes one slit having an open and a closed end. The tubular structure is further comprised of a tab defined by the slit whereby, when the tab is pulled apart from any object extending through the lumen of the tubular structure, the tubular structure tears longitudinally removing the tubular structure from the object. In another embodiment, the tubular structure is cuffed between the closed end of the slit and the distal end of the tubular structure, the cuff defining the proximal end of the tubular structure. The cuff prevents the slit from tearing prematurely and further provides a blunt, smooth open end at the proximal end that permits closure thereof by thumb pressure only in order to temporarily block blood flow or air aspiration during use.Type: GrantFiled: November 14, 1983Date of Patent: April 8, 1986Assignee: Cook IncorporatedInventor: Hans A.

Patent number: 4430081Abstract: Hemostasis cannula comprising a body having a passage therethrough adapted to receive a catheter and three side-by-side gaskets mounted in the passage. The gaskets form a seal around a catheter enclosed within the cannula. When the catheter is removed, the gaskets block air flow into the patient's blood vessel and also block blood flow out of the patient's blood vessel. The cannula also includes a flexible entrance tube and a port for introducing fluids into a patient's blood vessel.Type: GrantFiled: January 6, 1981Date of Patent: February 7, 1984Assignee: Cook, Inc.Inventor: Hans A.
