Publication number: 20120290976Abstract: Techniques for presenting a three-dimensional (3D) anatomical representation of an anatomical structure are described. 3D models of various anatomical structures may be stored as prepackaged anatomical data. A user device, e.g., a networked workstation, may receive the prepackaged anatomical data from a networked computing device, e.g., a server, and present at least a portion of a 3D model as a 3D anatomical representation. The user device may also present a menu with the 3D anatomical representation that allows the user to manipulate the 3D anatomical representation and measure various aspects of the 3D anatomical representation. In some examples, the user device may also present a representation of a medical device in conjunction with the 3D anatomical representation.Type: ApplicationFiled: May 13, 2011Publication date: November 15, 2012Applicant: MEDTRONIC, INC.Inventors: Ryan Phillip Lahm, Josee Morissette, Michael J.

Patent number: 8244360Abstract: Systems and methods for coordinated delivery of a therapeutic agent and low (less than about 20 Hz) and high (greater than about 50 Hz) frequency stimulation therapy are described. The systems include a control unit for coordinating therapy delivery between an infusion device and a pulse generator, such that a therapeutic agent is administered at a predetermined time relative to application of either low frequency or high frequency stimulation. For example, the control unit may instruct the infusion device to deliver therapeutic agent at a predetermined time prior to delivery of low frequency stimulation. Systems that include more than one infusion device or an infusion pump capable of delivering more than one therapeutic agent are also described.Type: GrantFiled: March 14, 2006Date of Patent: August 14, 2012Assignee: Medtronic, Inc.Inventors: Kenneth T. Heruth, Mark S. Lent, Ruchika Singhal, Michael J. Schendel

Publication number: 20120083866Abstract: An implantable lead is provided with at least one extendable member to position therapy delivery elements, which may be electrodes or drug delivery ports, after the lead has been inserted into the body. The lead may formed as a resilient element which is contained in a retainer tube that may be removed to permit the lead to deploy. Alternatively, a non-resilient lead may be provided with a slotted retainer tube. A series of mechanical linkages for expanding and retracting the lead within the human body may be actuated with various mechanisms. A control system may be provided for closed-loop feedback control of the position of the extendable members. The invention also includes a method for expanding an implantable lead in situ.Type: ApplicationFiled: December 14, 2011Publication date: April 5, 2012Applicant: Medtronic, Inc.Inventors: Gary W.

Patent number: 7890166Abstract: Enhanced therapies for treating pain are described. The therapies include subcutaneous stimulation of tissue in proximity to a source of pain at low frequencies (less than about 20 Hz) and high frequencies (greater than about 50 Hz). The therapies further include administering a pain treating agent at a predetermined time relative to application of the high or low frequency stimulation. Delivery of the pain treating agent via an implantable infusion system is described. Coordination of output of an infusion device and a pulse generator to provide coordinated therapy is also discussed.Type: GrantFiled: March 14, 2006Date of Patent: February 15, 2011Assignee: Medtronic, Inc.Inventors: Kenneth T.

Publication number: 20110004124Abstract: Systems and techniques for determining in vivo mechanical load exerted on an implanted medical device (IMD) are described. The IMD or a device that has a substantially similar form factor as the IMD includes at least one mechanical stress sensor mechanically coupled to a housing or a component within the housing. In some examples, a patient parameter is determined based on a signal indicative of the in vivo mechanical load exerted on the IMD. In addition, in some examples, a processor determines whether a transient or cumulative mechanical load exerted on an IMD exceeded a predetermined threshold. A processor may additionally or alternatively determine whether a pattern in the mechanical loading of the IMD indicates a diversion from a manufacturing, shipping, storage or other handling process.Type: ApplicationFiled: April 26, 2010Publication date: January 6, 2011Applicant: Medtronic, Inc.Inventors: Joseph F.

Patent number: 7813803Abstract: Enhanced therapies for treating pain are described. The therapies include subcutaneous stimulation of tissue in proximity to a source of pain at low frequencies (less than about 20 Hz) and high frequencies (greater than about 50 Hz).
