Patent number: 9389023Abstract: A capillary tube bundle sub-assembly for use in an extracorporeal heat exchanger includes a continuous capillary tubing wound about a core to define a plurality of capillary layers each including a plurality of capillary segments. The capillary segments each define opposing terminal ends adjacent opposing ends of the core. The capillary segments of each layer are circumferentially aligned relative to an axis of the core, with each successive layer being radially outward of an immediately preceding layer. The capillary segments are non-parallel with the axis, spiraling partially about the axis in extension between the opposing terminal ends. Each capillary segment forms less than one complete revolution (i.e., winds less than 360°). The segments within each layer are substantially parallel with one another; however, an orientation of the segments differs from layer-to-layer such as by pitch or angle.Type: GrantFiled: October 25, 2013Date of Patent: July 12, 2016Assignee: Medtronic, Inc.Inventors: Patrick Cloutier, Robert Olsen, Stephen Roller, Chris Plott, Al McLevish, Ming Li, Michael Laxen, John Knoll, Gregory Hake

Patent number: 8622950Abstract: A method of manufacturing a bundled mat construction for an extracorporeal blood circuit heat exchanger includes attaching a leading edge of a first capillary tube mat segment to a first side of a mandrel. A leading edge of a second capillary tube mat segment is attached to a second side of the mandrel. The first side is diametrically opposite the second side. The mandrel is rolled relative to the mat segments to generate a bundled mat construction. Radial layers of the bundled mat construction are symmetrical relative to a central axis of the mandrel.Type: GrantFiled: January 27, 2011Date of Patent: January 7, 2014Assignee: Medtronic, Inc.Inventors: Kevin Lauber, Robert Olsen, Mark Wendler, Chris Plott, Al McLevish

Patent number: 8518259Abstract: An apparatus for de-aering, oxygenating and controlling a temperature of blood in an extracorporeal blood circuit. The apparatus includes a housing, a manifold body, a heat exchanger, and an oxygenator. A blood inlet tangentially directs blood into a first chamber of the housing. The manifold body is disposed in a second chamber, and includes a core and a plurality of vanes that define channels. The heat exchanger is arranged around the manifold body, and the oxygenator around the heat exchanger. The channels are open to the heat exchanger. An established blood flow path includes rotational flow within the first chamber to separate air from the blood, generally longitudinal flow from the first chamber and along the channels, and generally radial flow through the heat exchanger and the oxygenator. With this construction, gross air removal occurs prior to the blood passing through the heat exchanger and oxygenator.Type: GrantFiled: January 27, 2011Date of Patent: August 27, 2013Assignee: Medtronic, Inc.Inventors: Patrick Cloutier, Robert Olsen, Stephen Roller, Chris Plott, Al McLevish, Ming Li, Michael Laxen, John Knoll, Gregory Hake

Publication number: 20110147550Abstract: A mounting system for mounting one or more components of an extracorporeal blood circuit to an upstanding mast provided with a pump cart. The system includes a clamp device, a primary arm, a seat, a post, and a locking mechanism. The clamp device is mountable to the mast and pivotably maintaining the primary arm. The seat defines a tapering intermediate section and is mounted to the primary arm. The post projects from the seat. Finally, the locking mechanism is configured to releasably secure an extracorporeal circuit component, otherwise located over the seat, to the primary arm. With this configuration, the extracorporeal circuit component can be selectively located and locked to the primary arm at a variety of different rotational orientations. The mounting system can further include an auxiliary arm defining a sleeve sized to be removably disposed over the seat.Type: ApplicationFiled: December 17, 2009Publication date: June 23, 2011Applicant: Medtronic, Inc.Inventors: Mark Wendler, Al McLevish, Chris Plott, Joe Cardinal, Mike Hobday, Roderick Briscoe
