Patent number: 11318302Abstract: A transseptal catheter delivery system includes an elongate first tubular member and an elongate second tubular member receivable within the first tubular member. The first tubular member includes an adjustable portion adjacent a distal end. The second tubular member is adapted to receive an instrument to be placed in the left ventricle, and includes a curved portion adjacent its distal end in a relaxed state. The adjustable portion is deflectable toward the atrial septum to guide a puncturing tool and/or guide insertion of the second tubular member through a septal puncture into the left atrium. Within the left atrium, the curved portion is oriented toward the left ventricle to guide insertion of a guide wire, and subsequently the second tubular member, into the left ventricle. Methods of transvenously accessing a left ventricle are also provided.Type: GrantFiled: July 30, 2019Date of Patent: May 3, 2022Assignee: Medtronic, Inc.Inventors: Andrea J. Asleson, Zhongping Yang, Michael W. Kimmel, Kyle R. Marquard, Laurie D. Foerster

Patent number: 9314572Abstract: Devices, systems, and techniques for transitioning between different drug delivery sources or different drug concentrations may account for diffusion and mixing of drug within the fluid. In one example, a method may include determining a flow rate for a fluid to be delivered to a patient via a drug pump and a catheter in fluid communication with a reservoir of the drug pump. The fluid includes a drug. The method also includes determining a concentration profile of the drug delivered via the catheter, wherein the concentration profile identifies a volume of delivered fluid needed to achieve a target transition dose of the drug. The method further includes determining, by a processor and based on the flow rate and the concentration profile, an initial delivery period required to achieve the target transition dose by delivering the fluid at the flow rate.Type: GrantFiled: November 11, 2013Date of Patent: April 19, 2016Assignee: MEDTRONIC, INC.Inventors: Mary M. Morris, Mark A. Bellrichard, Robert Garfield, Daniel Gelfman, Lu Wang, Michael W. Kimmel, Karen J. Kleckner, Brian W. Ball

Patent number: 9302078Abstract: Systems for gaining access into a body of a patient around an implanted body of an elongate medical device include a sheath having a deformable wall that allows insertion of the device body into a lumen surrounded by the sheath wall. The sheath wall may include first and second edges that extend from a proximal end to a distal end of the lumen, or just extend along a distal portion of the lumen. A tool, which includes a groove sized to grasp about a circumference of the device body, may facilitate insertion of the device body into the lumen of those sheath embodiments that include the first and second edges, by spreading at least one of the first and second edges of the wall apart from the other of the first and second edges while the device body is grasped within the tool.Type: GrantFiled: July 28, 2011Date of Patent: April 5, 2016Assignee: Medtronic, Inc.Inventors: Randy A. Lieberman, Steven L Waldhauser, Javier J Echenique, Lonnie D. Ronning, Linnea R. Lentz, Kimberly A. Oleson, Deanna K. Levenhagen, Phillip C. Falkner, Michael W. Kimmel
