  • Patent number: 6895276
    Abstract: Implantable medical devices (IMDs) comprising a monitor or implantable pulse generator (IPG) having an IPG header to which lead connector assemblies of electrical medical leads are coupled, particularly, an improved in-line IPG header providing enhanced durability, ease of manufacture, and ease of use. A stack of alternating, substantially tubular electrically insulating fluid seals and header connector elements is assembled in axial alignment to form a common, elongated axial stack bore sized in diameter and length to receive the lead connector assembly. Each adjacent electrical connector element and fluid seal are interlocked with one another during assembly of the stack to maintain the axial alignment and the length and diameter dimensions. Fluid seals are located at each end of the stack, and the stack can be inserted as a unit into a cavity of the IPG header.

  • Patent number: 6725096
    Abstract: A tool-less connector with multiple contacts and a compact design is provided. Therefore, a connector that is normally tunneled through body tissue will now require only a minimally invasive subcutaneous tunnel, which should reduce tissue healing time, patient discomfort, and risk of infection. In addition, providing additional contacts allows enhanced stimulation protocols. One embodiment of the present invention provides a connector pin containing multiple in-line contacts. Each “line” consists of a row of independent contacts arranged in a linear array running along the long axis of the pin. In other embodiments of the invention, the mating receptacle of the connector allows for multiple contacts while minimizing the space required for the increased number of contacts. Additional embodiments provide features that, for instance, prevent the contacts on the connector pin to touch the contacts in the receptacle until all contacts are appropriately aligned.

  • Patent number: 6368141
    Abstract: An improved insertion set is provided for transcutaneous placement of a sensor such as a glucose sensor at a selected site within the body of a patient. The insertion set comprises a mounting base defining an upwardly open channel for receiving and supporting a flexible thin film sensor, in combination with a cap assembled with said mounting base to capture and retain a proximal end of the sensor within said channel. The sensor further includes a distal segment with sensor electrodes thereon which protrudes from the mounting base for transcutaneous placement, wherein the sensor distal segment is slidably carried by a slotted insertion needle fitted through the assembled base and cap. Placement of the insertion set against the patient's skin causes the insertion needle to pierce the skin to carry the sensor electrodes to the desired subcutaneous site, after which the insertion needle can be slidably withdrawn from the insertion set.

  • Patent number: 6357089
    Abstract: A clip for a sheet electrode, which is capable of easily and reliably pinching a sheet electrode, and capable of minimizing the number of parts, thus facilitating the assembling. This clip is constructed such that a movable plate (20) provided with slots (25) to be engaged with supporting axes (13) is engaged with a substrate (10) having the supporting axes (13), and a conductive leaf spring (30) which is bent in the near middle thereof is interposed between the substrate and movable plate so as to keep them in an opened state. After the insertion of a sheet electrode (50), the movable plate is pivoted against the force of the leaf spring so as to close and pinch the sheet electrode. When the movable plate is further shifted forward along the slots, the movable plate is fixingly engaged with the substrate, thereby maintaining the pinching of the sheet electrode.

  • Patent number: 6356778
    Abstract: A connector assembly for a fetal scalp electrode for use in monitoring fetal heart rate. The connector assembly is used in conjunction with a fetal monitor coupling device and includes a holder formed of an insulating material and a fetal electrode and a maternal electrode secured to the holder. Each wire of an insulated pair of elongated flexible wires is electrically connected to a respective one of the fetal and maternal electrodes. The connector assembly further includes a connector having a pin contact electrically connected to one of the wires and a cylindrical contact electrically connected to the other of the wires. The cylindrical contact is mounted coaxially with the pin contact so that the contacts are electrically isolated from each other and are positioned to make electrical contact with complementary contacts in the coupling device. The connector assembly also preferably includes an elongated tubular sheath that covers the connector and is sized to be received in the coupling device.

  • Patent number: 6350160
    Abstract: A medical connector and adapter system that includes: a male cable connector, and a female cable-receiving housing for electrically coupling with the male cable connector. The male cable connector has a protrusion that is adapted to slide over the wall of the female cable-receiving housing. In one embodiment, the protrusion prevents the male cable connector from mating with a female cable-receiving housing that is incorporated into the housing of a defibrillator when there is no accommodation in the defibrillator housing to receive the protrusion. Further the male cable connector is electrically connected to pediatric electrodes and enables pediatric electrodes to be used with a manual defibrillator.

  • Patent number: 6349228
    Abstract: An adapter allows the interconnection of a sensor originating from one manufacturer to be coupled with conventionally incompatible monitors originating from other manufacturers to form a properly functioning pulse oximetry system. The adapter matches a sensor driver in a monitor to the current requirements and light source configuration of a sensor. The adapter also matches a sensor's light detector signal level to the dynamic range requirements of a monitor preamplifier. Further, the adapter provides compatible sensor calibration, sensor type and security information to a monitor. The adapter may have a self-contained power source or it may derive power from the monitor, allowing both passive and active adapter components. The adapter is particular suited as an adapter cable, replacing a conventional patient cable or sensor cable as the interconnection between a sensor to a monitor in a pulse oximetry system.
