  • Patent number: 9589698
    Abstract: The invention relates to a conductive elastomer provided and formed from a base elastomer and conductive solid particles that are distributed therein. The conductive particles used are: a) platelet-shaped conductive particles and/or b) dendritic conductive particles and/or c) other elongated conductive particles with a length:width ratio of greater than or equal to two. It has been seen that a combination of ball-shaped and platelet-shaped conductive particles is particularly advantageous. The particles can additionally be aligned by the pouring, application using a doctor blade, or drawing of the dissolved or not-yet cured mixture. The polymer is particularly suitable for medical electrodes for capturing and emitting signals. The material rennulus elastic, and conductive when stretched or bent.

  • Publication number: 20100036231
    Abstract: Size-specific electrical connector apparatus optimized for e.g., biomedical applications, and which prevents mating to the wrong sized terminals. In one embodiment, the connector apparatus comprises device having a two piece assembly adapted pivotally engage and lock a sensor such as those used in impedance cardiography (ICG) therein. The conductor is shaped so as to provide a high degree of specificity in sensor connection as well as signal stability and reliability. In one variant, the pivot comprises a spring-loaded pivot having no external stops and the shape of a sensor engaging aperture is defined by a metal insert associated with one element of the assembly and the pivot is permanently formed within the connector. Thus, a user is obstructed from changing the properties of the connector to accept smaller or larger sensors. Methods of manufacturing and operating the connector are also disclosed.

  • Publication number: 20090149731
    Abstract: Disclosed is an ECG electrode lead wire connector which provides improved electrical and mechanical coupling of the ECG electrode press stud to the lead wire, provides enhanced ergonomics to the clinician, and may alleviate patient discomfort associated with the attachment and removal of ECG leads. The connector may be engaged and disengaged with little or no force imparted to the patient or the ECG pad, which significantly minimizes the risk of inadvertent dislodgement of the pad. In one embodiment the disclosed connector provides a thumb cam lever which affirmatively engages the press stud to the connector, and provides tactile feedback to the clinician that the connector is properly engaged. In other embodiments, the connector provides a pushbutton to enable the clinician to easily engage and disengage the connector from the ECG stud. The disclosed connectors may also decrease clinician fatigue, and may provide more reliable ECG results.

  • Patent number: 7347826
    Abstract: According to this technique of packaging a sensor device implantable in a living body so as to provide protection of the sensor device and to the living body itself, an electrical conductor of the sensor device is sealed in an insulating substrate extending between proximal and distal ends. The distal end of the electrical conductor is externally connected to an external sensor on the sensor device and the proximal end of the electrical conductor is externally connected to a distal end of a lead wire extending proximally to a pulse generator and these connections are embedded in an insulative sheath. The external sensor, substrate, and insulative sheath are encapsulated in a thin film of hermetic material without interference with the lead wire. In another embodiment, a layer of insulating material may underlie the hermetic material to encapsulate the external sensor and the substrate.

  • Patent number: 7245957
    Abstract: A medical snap electrode having a conductive tape portion disposed between the cover material and conduction layer of the electrode. The conductive tape portion becomes part of an electrical connection from a top snap, positioned above the cover material, to the conductive tape then to the conductive layer. The conductive tape includes conductive adhesive on at least one of its surfaces and thereby provides a more robust electrical connection from a top snap to a conductive layer in the electrode and ultimately to a subject's skin. Viewing of the snap through the conductive film layer is prevented. The conductive tape thus provides an improved conduction path for distributing electrical current from the top snap to a subject's skin in addition to the conduction path through bottom snap. The improved conduction path can prevent heating or apprehension of potential heating by a subject or clinician.
