Publication number: 20230230684Abstract: The present disclosure provides a catheter design tool and methods thereof for selecting or designing an optimal catheter profile for a particular patient or group of patients. For example, the tool includes a data set (e.g., input into the system) pertaining to a plurality of anatomy parameters and a plurality of catheter parameters to determine one or more catheter profiles that allow the best implant efficacy for a particular patient or group of patients. Specifically, the tool evaluates the efficacy of a particular catheter profile for use with a particular patient, the most optimal catheter profile from a plurality of catheter profiles for use with a particular patient, and/or the most optimal catheter profile from a plurality of catheter profiles for use with a group of patients.Type: ApplicationFiled: December 16, 2022Publication date: July 20, 2023Inventors: Megan Samec, Varun A.

Patent number: 11559669Abstract: The medical device may comprise an elongate body having a proximal portion, a distal portion, and defining a lumen therethrough. Also, the medical device may include an expandable element coupled to the distal portion of the elongate body and in fluid communication with the lumen. The expandable element may define a first end and a second end, the second end being proximal to the first end. The medical device may further include a cannula surrounding at least a portion of the elongate body and the cannula may define a proximal end and a distal end. The distal end of the cannula may be disposed proximal and adjacent to the second end of the expandable element. An outer dimctcr diameter of the cannula may be substantially equal to or lesser than an outer diameter of the expandable element when inflated. The medical device may be maneuvered through a patient's body.Type: GrantFiled: April 4, 2019Date of Patent: January 24, 2023Assignee: MEDTRONIC, INC.Inventors: Andrea J. Asleson, Michael P. Campbell, Teresa Whitman, Keith D. Anderson, Bridget A. Portway

Patent number: 11559679Abstract: A fixation mechanism of an implantable lead includes a plurality of depressions of an outermost surface of the lead and a relatively flexible sleeve mounted around the outermost surface. The depressions are spaced apart from one another along a length, and each extends circumferentially, wherein a longitudinal center-to-center spacing between each adjacent depression is uniform along the length, and each depression is of substantially the same size. The sleeve has an internal surface in sliding engagement with the outermost surface of the lead, and an external surface, in which suture grooves are formed. A longitudinal center-to-center spacing between adjacent suture grooves may be substantially the same as, or a multiple of, the longitudinal center-to-center spacing between adjacent depressions of the outermost surface of the lead. The sleeve may also include a ridge protruding from the internal surface, aligned with, or offset (by center-to-center spacing of depressions) from, the grooves.Type: GrantFiled: March 30, 2020Date of Patent: January 24, 2023Assignee: Medtronic, Inc.Inventors: Kevin R. Seifert, Maggie J. Pistella, Thomas D. Brostrom, Keith D. Anderson, Gareth Morgan

Patent number: 11027124Abstract: A tool operable with a catheter in an interventional medical system retrieves a medical device from an implant site, wherein the device includes an attachment feature that forms an annular recess to be engaged by a lasso of the tool for snaring the device, and a distal-most sidewall of the catheter defines a receptacle into which the snared device is retrieved. A guide of the tool includes a sidewall defining a lumen in which the lasso extends for deployment out from a distal opening thereof, to snare and retrieve the implanted device. The sidewall establishes a radial offset between the guide lumen distal opening and the distal-most sidewall of the catheter, when the guide lumen distal opening and a distal opening of the receptacle are located in close proximity to one another, which radial offset is greater than a length of the annular recess formed by the device attachment feature.Type: GrantFiled: September 13, 2016Date of Patent: June 8, 2021Assignee: MEDTRONIC, INC.Inventors: Ronald A Drake, Keith D Anderson, Kenneth C Gardeski, Dina L Williams
