摘要： A conductor assembly for a medical electrical lead includes a web and plurality of conductors. The web includes a plurality of longitudinally extending elements, or sidewalls, each of which define a longitudinally extending lumen, and a plurality of longitudinally extending connectors, each of which join a pair of adjacent sidewalls. Each of the plurality of conductors extends within a corresponding lumen, and each may include an insulative jacket. If each conductor includes an insulative jacket, the jacket is preferably formed from one or more of the following materials: PEEK, PVDF and polysulfone. One or more of the connectors of the web may be flexible to allow for a connected separation, or a gap between adjacent sidewalls; and one or more of these connectors may further include a discrete wall section adapted to facilitate widening of the corresponding gap. Preferably the conductor assembly is coiled for incorporation into the lead.

摘要： 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.

摘要： 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.

摘要： An implantable medical device (IMD) can include a cardiac pacemaker or an implantable cardioverter-defibrillator (ICD). Various portions of the IMD, such as a device body, a lead body, or a lead tip, can be provided to reduce or dissipate a current and heat induced by various external environmental factors. According to various embodiments, features can be incorporated into the lead body, the lead tip, or the IMD body to reduce the creation of an induced current, or dissipate the induced Current and heat created due to an induced current in the lead. For example, an IMD can include at least one outer conductive member and a first electrode. The first electrode can be in electrical communication with the at least one outer conductive member. The first electrode can dissipate a current induced in the at least one outer conductive member via a first portion of the anatomical structure.

摘要： 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.
