Publication number: 20130253343Abstract: In one example, this disclosure is directed to a kit for intravascular implantation of an implantable medical device within a patient, the kit comprising an elongated outer sheath forming a first inner lumen with a distal opening, the outer sheath sized to traverse a vasculature of the patient, and an elongated inner sheath forming a second inner lumen. An outer diameter of the inner sheath is smaller than the diameter of the first inner lumen such that the inner sheath fits within the first inner lumen, wherein the inner sheath is slidable within the first inner lumen. The second inner lumen at a distal end of the inner sheath is configured to carry an implantable medical device. The inner sheath forms a slit at a distal end of the inner sheath to facilitate deployment of the implantable medical device out of the distal opening of the outer sheath.Type: ApplicationFiled: May 29, 2012Publication date: September 26, 2013Applicant: MEDTRONIC, INC.Inventors: Steven L. Waldhauser, Kelly M. Wien, Kendra Yasger

Patent number: 8486089Abstract: Devices and methods for implanting leads along a spinal cord include an introducer having a main body defining a lumen and one or more collapsible and expandable side sheaths attached to the main body. The side sheaths may be collapsed as the introducer is positioned in a desired location of a patient to maintain a low profile. Once the introducer is placed, the side sheaths may be expanded to receive a lead. A lead may also be inserted through a lumen of the main body. Once the leads are inserted, the introducer may be withdrawn over the leads, leaving the leads implanted in the desired region in a desired orientation.Type: GrantFiled: February 16, 2010Date of Patent: July 16, 2013Assignee: Medtronic, Inc.Inventors: Phillip C. Falkner, Eric H. Bonde, Dale F. Seeley, Patrick P. Senarith, Steven L. Waldhauser, Kendra Yasger

Publication number: 20090326630Abstract: A medical apparatus includes an electrically conductive lead for a medical device, the lead having an internal bore terminating at a distal lead opening, and a lead delivery device for delivering the distal end of the lead to a blood vessel during implantation of the lead. The lead delivery device includes a removably anchorable guidewire, and a fixator attached to a distal portion of the guidewire for anchoring the guidewire. The fixator is movable between a compact configuration and an expanded configuration. The fixator is capable of passing through the distal lead opening of the lead in the compact configuration.
