Abstract: An ergonomically designed wireless wearable smart band pair for continuous ECG monitoring is disclosed. The pair comprises primary and secondary smart bands with integrated electrodes. When the smart bands are worn around the two limbs, electrodes contact the skin. The primary smart band acquires biopotential data from the first wrist while the secondary smart band simultaneously acquires biopotential data from the second wrist and sends it wirelessly to the primary smart band. The primary smart band processes biopotential data via DSP and analog signal conditioning, and fuses information to acquire high-fidelity ECG data as per Einthoven's law without need for completing a circuit via leads and/or holding auxiliary electrodes. The primary smart band analyzes ECG data in real-time, generates pertinent alarms, stores data locally, and wirelessly transmits information to external devices.

Abstract: Methods and devices to facilitate positioning of a catheter into a vessel. Devices include axially concentric assemblies of a piercing needle and a dilator that guides an outer catheter into a vessel, such as a blood vessel. The assemblies described herein can include retraction mechanisms and/or lock mechanisms to control needle positioning during catheterization processes as well as improved valves that prevent leakage of fluid from the proximal end of the devices. The devices and method include the use of novel valves to prevent undesired leakage of fluids through the proximal end of the catheter.

Abstract: An electrically or manually actuated locking device comprising a magnetic reed switch as a sensor to monitor whether or not the device is locked. The reed switch is mounted on a circuit board to make a sub-assembly and the sub-assembly is coated with a plastic or other synthetic material which is impermeable to water and/or oil and which provides a degree of mechanical protection from breakage. The coated sub-assembly is then mounted within a housing incorporating the locking device. A pivotable magnet carrier which pivots when the bolt of the locking device is engaged causes the reed switch to be actuated.

Abstract: This invention describes a wearable device related to electrocardiogram (ECG) monitoring technology. An ergonomically designed wireless smart band pair for continuous ECG monitoring and analysis is disclosed. The pair comprises a primary and a secondary smart band with integrated electrodes. When the smart bands are worn around the two wrists, the electrodes contact the skin. The primary smart band acquires biopotential data from the first wrist while the secondary smart band acquires biopotential data from the second wrist and sends it wirelessly to the primary smart band. The primary smart band processes biopotential data from both wrists to acquire high-fidelity ECG data as per Einthoven's law without the need for completing a circuit via leads and/or touching and holding auxiliary electrodes. The primary smart band analyzes the acquired ECG data in real-time and generates pertinent alarms. It also stores all ECG information locally and wirelessly transmits this information to external devices.

Abstract: An orientation device (200) for use in mitral valve repair surgery is provided and includes a catheter (202) catheter insertable percutaneously through the mitral valve into a chamber of a heart. At least one pressure sensor (216, 218) and two generally arcuate commissural arms (208, 210) are provided at or near the distal end (204) of the catheter (202). The arms (208, 210) are deployable from a stowed condition, in which the catheter (202) can be introduced percutaneously into the heart, to an operative condition in which they extend outwardly in generally opposite directions. Each arm (208, 210) is shaped to be locatable within a mitral valve commissure and has an indentation (212) shaped to extend, in use, at least partially about a mitral valve commissure to limit movement of the device (200) relative to the mitral valve in the axial direction of the catheter (202).

Abstract: A crimping device includes a housing defining a bore and at least three extendable mechanisms angularly equispaced about the axis of the bore. Each of the extendable mechanisms include: (i) a first elongate arm hingedly connected at or near a first axial end of the first arm to the housing; (ii) a second elongate arm hingedly connected at or near a first axial end of the second arm to the housing, wherein: the first axial ends of the first and second arms are displaceable relative to each other; and the first and second arms are hingedly connected at or near their second axial ends to each other.

Abstract: A dual tip dialysis catheter has a proximal portion with connected lumens and a distal portion with diverging lumens. The lumens may separate at a split junction and diverge in a scissors like manner to reduce or eliminate a crack or gap adjacent to the split junction, thereby reducing clotting. A dual tip dialysis catheter may have forward openings configured to direct flow in opposite directions.
