Abstract: Provided is an apparatus and method of measuring a pulse wave. The method includes: causing receivers to respectively receive pulse wave signals that are detected at two points of an object, determining an effective pulse wave signal period by using the received pulse wave signals, and obtaining a pulse transit time (PTT) between the two points by using a result obtained after comparing a magnitude of an output signal of each of the receivers with a value that is less by a predetermined percentage than a peak value of an output signal of each of the receivers during the determined effective pulse wave signal period.

Abstract: A signal processing arrangement generates electrode stimulation signals to stimulation contacts in a cochlear implant electrode array. A signal filter bank transforms an input sound signal into band pass signals, which each represent an associated frequency band of audio frequencies. An envelope processing module processes the band pass signals in a sequence of sampling time frames, wherein for each time frame, the processing includes calculating for each band pass signal at least one signal envelope dynamic property that is changing during the time frame. A channel selection module selects one or more of the band pass signals for each time frame based on the dynamic properties to produce the electrode stimulation signals to the stimulation contacts.

Abstract: A catheter may include an outer layer defining a plurality of apertures therethrough, and a body defining at least one longitudinal lumen therein. The body may be within the outer layer, and the apertures may be radially outward of the lumen. The catheter may also include a plurality of electrodes positioned in or on the catheter, with each electrode being electrically exposed through an aperture of the plurality of apertures. A ribbon cable may extend through the lumen and include a plurality of leads, with the plurality of leads being electrically connected to the plurality of electrodes. The plurality of leads and electrodes may be formed by the deposition of conductive inks or paints, or by the electrodeposition of copper or other conductive metals or materials.

Abstract: The invention relates to an electrical multichannel system (100) and to a neural stimulation and/or recording device comprising such a system. The multichannel system comprises a plurality of application components (130), e.g. stimulation electrodes, and associated access points (120) that are connected by a plurality of electrical lines (110). The resistances of these lines are adjusted to given target values, for example to equal values, by incorporating appropriate tuning sections (140) into the electrical lines. The lines may for example comprise different geometries and/or materials in the tuning sections.

Abstract: Various aspects of the present disclosure are directed toward methods, apparatuses, and systems that include an implantable medical device comprising an implantable lead, a suture sleeve having an interior surface defining a lumen of the suture sleeve that receives the implantable lead, and an engagement feature configured to non-removeably secure the suture sleeve to the implantable lead.

Abstract: A burr hole plug includes a first plug base defining a burr hole aperture and including first grooves; a second plug base to be disposed around the first plug base and including second grooves to receive a portion of an electrical stimulation lead; a cover to be disposed on the second plug base; a cap to be disposed over the burr hole aperture and coupled to the first plug base; and an extension coupled to, and extending away from, the cover. The extension includes conductors and the second plug base and the cover include conductive elements to electrically couple the terminals of the electrical stimulation lead, when disposed in the second grooves, to the conductors of the extension. An alternative burr hole plug includes a lead connector disposed on the cap and having a connector aperture to receive the proximal end of the electrical stimulation lead.
