Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61M 5178

US Classification:

60416401, 606159

Abstract:

An introducer that includes a tubular outer sheath having proximal and distal ends, a tubular inner sheath having proximal and distal ends, rotatably mounted within the outer sheath, and a knob, positioned at the proximal end of the inner sheath, so that the inner sheath is rotatable through the knob. A gripping mechanism is coupled to the distal end of the inner sheath and rotatable with the inner sheath to compressively engage a distal portion of a lead or catheter extending through the inner sheath in response to the rotation of the inner sheath through the knob.

International Classification:

A61N 1/05

US Classification:

607 9, 607 15, 607 17, 607 18

Abstract:

A medical system comprises a plurality of electrodes; at least one sensor configured to output at least one signal based on at least one physiological parameter of a patient; and a processor. The processor is configured to control delivery of stimulation to the patient using a plurality of electrode configurations. Each of the electrode configurations comprises at least one of the plurality of electrodes. For each of the electrode configurations, the processor is configured to determine a first response of target tissue to the stimulation based on the signals, and a second response of non-target tissue to the stimulation based on the signals. The processor is also configured to select at least one of the electrode configurations for delivery of stimulation to the patient based on the first and second responses for the electrode configurations. As examples, the target tissue may be a left ventricle or vagus nerve.

International Classification:

A61N 1/362
A61N 1/05

US Classification:

607 30, 607 9

Abstract:

A system includes an implantable electrical stimulation lead configured for intravenous introduction into a vessel proximate to a heart and an electrical stimulator. The lead comprises a lead body and at least three electrode segments. The electrical stimulator is coupled to the electrode segments and configures a first of the electrode segments as a first anode, a second of the electrode segments as a cathode, and a third of the electrode segments as a second anode, and delivers electrical stimulation to the heart via the cathode and first and second anodes. Additional techniques for delivering electrical stimulation include using multiple electrode segments as cathodes and electrically isolating other electrode segments. Other examples are directed to techniques for directing electrical therapy to a vagus nerve of a patient.

Appl. No.:

12/423428

Inventors:

Terrell M. Williams - Brooklyn Park MN, US
Mark T. Marshall - Forest Lake MN, US

Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61N 1/05

US Classification:

607122

Abstract:

An extendable medical lead comprises a lead body and a sheath defining a cavity that encloses a length of the lead body. The length of the lead body enclosed within the sheath may be coiled or otherwise gathered such that when extended, the length of the enclosed section of the lead body is greater than the length of the sheath. The sheath may include a seal to help prevent contaminant entry into the cavity in order to help reduce tissue in growth around the length of the lead body disposed within the sheath. A portion of the length of the lead body enclosed within the sheath exits the cavity through an aperture defined by the seal when a tensile force is applied to the lead body.
