An implantable medical device lead includes an inner conductor coil comprising one or more generally cylindrically wound filars. The inner conductor coil is configured to have a first inductance value greater than or equal to 0.2 &#x3bc;H/inch when the inner conductor coil is subjected to a range of radio frequencies. The implantable medical device lead also includes a multi-filar outer coil comprising two or more generally cylindrically wound filars. The multi-filar outer coil is configured to have a second inductance value greater than or equal to 0.1 &#x3bc;H/inch when the multi-filar outer coil is subjected to the range of radio frequencies.

Lead including conductors configured for reduced MRI-induced currents

In an embodiment, the invention includes an implantable medical device with a pulse generator and a chemical sensor in communication with the pulse generator, the chemical sensor configured to detect an ion concentration in a bodily fluid. In an embodiment, the invention includes a method for providing cardiac arrhythmia therapy to a patient including sensing a physiological concentration of an analyte, communicating data regarding the physiological concentration of the analyte to an implanted pulse generator, and delivering therapy to the patient based in part on the physiological concentration of the ion. In an embodiment, the invention includes a method for monitoring diuretic therapy. In an embodiment, the invention includes a method for controlling delivery of an active agent into a human body. Other aspects and embodiments are provided herein.

Implantable medical device with chemical sensor and related methods

Systems and methods for improving response of implantable leads to magnetic fields during medical procedures such as magnetic resonance imaging (MRI) are described. In various embodiments, the lead includes an inner conductor that is helically shaped and radially surrounded, at least in part, by one or more high-voltage conductors. The high-voltage conductor can be mechanically and/or electrically coupled, via a coupler, to the shocking coil. The pitch of the inner and/or outer conductor can be varied (e.g., continuously or at certain points) along the length of the lead. In some embodiments, the filar thickness, the pitch, and the mean coil diameter of the inner coil, the high voltage conductor coil, and the shock coil can be configured such that these coils have a desired inductance value when subjected to externally applied electromagnetic energy at radio frequencies commonly generated by MRI scanners (e.g., 40 MHz to 300 MHz).

Various embodiments relating to MRI safe, multi-polar active fixation stimulation leads with co-radial construction are disclosed. Some embodiments, allow the use of the generally smaller diameter co-radially constructed body (coated wires) to construct an active fixation lead, with an extendable/retractable fixation mechanism. Some embodiments use a connector assembly with an inner terminal ring, a terminal pin partially rotatably positioned within the annular inner terminal ring, and one or more resilient C-clips disposed within circumferential recesses. The resilient C-clips mechanically and electrically couple the inner terminal ring and the terminal ring while substantially limiting relative longitudinal translation of the terminal pin. In some embodiments, the connector assembly can be connected to an electrically inactive torque tube disposed longitudinally within the flexible body of the lead such that rotation of the terminal pin relative to the lead body causes rotation and longitudinal translation of a fixation helix relative to the body.

MRI safe, multipolar active fixation stimulation lead with co-radial construction

A system delivers stimulation to volume receptors in the cardiovascular system to induce diuresis in a patient suffering volume overload. The system senses a volume signal indicative of a level of fluid retention in the patient's body and controls the delivery of the stimulation using the volume signal. In various embodiments, the stimulation includes one or more of electrical stimulation, which delivers electrical pulses to the volume receptors, and mechanical stimulation, which physically stretches the volume receptors.

Method and apparatus for regulating blood volume using volume receptor stimulation

In one method of making an organic electroluminescent device, a transfer layer is solution coated on a donor substrate. The transfer layer includes an amorphous, non-polymeric, organic matrix with a light emitting material disposed in the matrix. The transfer layer is then selectively patterned on a receptor. Examples of patterning methods include laser thermal transfer or thermal head transfer. The method and associated materials can be used to form, for example, organic electroluminescent devices.

In a method of making an organic electroluminescent device, a transfer layer is solution coated on a donor substrate. The transfer layer includes a polymerizable, amorphous matrix with a light emitting material disposed in the matrix. The transfer layer is then selectively patterned on a receptor. The polymerizable, amorphous matrix is then polymerized. Examples of patterning methods include laser thermal transfer or thermal head transfer. The method and associated materials can be used to form, for example, organic electroluminescent devices.

Light emitting polymers can include a plurality of arylene monomeric units and a plurality of soft segment units independently selected from soft segment end caps; soft segment side chains coupled to a portion, but not all, of the arylene monomeric units; internal soft segment monomeric units; and combinations thereof. These light emitting polymers can be used in forming electroluminescent devices or other articles.

Electroluminescent materials and methods of manufacture and use

The invention provides compositions, organic electronic devices, and methods for preparing organic electronic devices. The compositions include a small molecule that is combined with at least one other material selected from a charge transporting material, a charge blocking material, a light emitting material, a color conversion material, or a combination thereof. The first compound has an aromatic core and two to four identical end capping groups attached to the aromatic core. The second compound has at least some structural similarities to the first compound of the composition.

Materials for organic electronic devices

Compounds and compositions are provided that can be used as electron transport agents in organic electronic devices such as organic electroluminescent devices. The compounds are non-polymeric and have an aromatic core conjugated to end capping groups. The aromatic core contains a phenylene group arylene or naphthalene group arylene having a pendant heteroaryl group that includes a &#x2014;C&#x2550;N&#x2014; unit.
