Patent number: 11969233Abstract: A method for monitoring a cardiovascular pressure in a patient includes measuring, by pressure sensing circuitry of an implantable pressure sensing device, the cardiovascular pressure of the patient. The method further includes transmitting, via wireless communication circuitry of the implantable pressure sensing device, the measured cardiovascular pressure to another device. The method further includes determining, by processing circuitry of the other device, whether a posture of the patient at a time of the measured cardiovascular pressure was a target posture for cardiovascular pressure measurements. The method further includes determining, by the processing circuitry of the other device, whether to store or discard the transmitted cardiovascular pressure based on determining whether the posture was the target posture.Type: GrantFiled: May 28, 2020Date of Patent: April 30, 2024Assignee: Medtronic, Inc.Inventors: Mary M. Morris, Ruth N. Klepfer, Karen J. Kleckner, Joel R. Lauer

Publication number: 20220023621Abstract: An implantable medical lead comprising a lead body defining a lumen. The lead body includes one or more tines substantially at a distal end of the lead body. An inner member extending within the lead body lumen is configured to rotate relative to the lead body and configured to cause a rotation of a dilator. The dilator is configured such that the rotation causes or enables a lateral translation of the dilator from a first position proximal to a lead body opening to a second position distal to the lead body opening. The implantable medical lead may include a probe wire configured to slidably translate through an inner lumen of the dilator.Type: ApplicationFiled: July 16, 2021Publication date: January 27, 2022Inventors: Ronald A.

Patent number: 10835133Abstract: A method for monitoring a cardiovascular pressure in a patient may include storing, in a memory of an implantable medical device system and in association with each one or more different patient postures, a respective offset value for the cardiovascular pressure of the patient. The one or more offset values may be determined based on a distance between an implantable pressure sensing device and an anatomical structure of the patient, a location of the implantable pressure sensing device within the patient, or one or more dimensions an anatomical structure of the patient. The method further includes determining a measured value of the cardiovascular pressure and a posture of the patient when the value of the cardiovascular pressure was measured, selecting a stored offset value associated with the current patient posture, and determining an adjusted cardiovascular pressure value based on the selected offset value and the measured cardiovascular pressure value.Type: GrantFiled: December 20, 2016Date of Patent: November 17, 2020Assignee: Medtronic, Inc.Inventors: Mary M.

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.

Patent number: 8852173Abstract: Methods and systems for transvenously accessing the pericardial space via the vascular system and atrial wall, particularly through the superior vena cava and right atrial wall, to deliver a pharmacologic agent, particularly a NO-donor drug, to the heart are disclosed. A proximal connector of an infusion catheter is coupled to an infusion pump, and a distal catheter segment having a distal infusion catheter lumen end opening is disposed in the pericardial space. The implantable infusion pump is operable in conjunction with an implantable ischemia monitor to monitor the ischemic state and trigger delivery or regulate the periodic delivery of the pharmacologic agent to optimally treat ischemia. The patient may operate a patient activator that the patient when feeling ischemia symptoms to transmit a signal that is received by the implantable infusion pump and triggers delivery of a bolus and/or continuous infusion.Type: GrantFiled: October 14, 2011Date of Patent: October 7, 2014Assignee: Medtronic, Inc.Inventors: Daniel C.
