Abstract: An irrigated ablation catheter includes a tip electrode with a thin shell and a plug to provide a plenum chamber. The tip electrode has an inlet of a predetermined size and noncircular shape, and outlets in the form of fluid ports formed in the thin shell wall. The plurality of the fluid ports is predetermined, as is their diameter. Each fluid port has a tapered configuration, for example, a frustoconical configuration, with a smaller inlet diameter and a larger outlet diameter.

Abstract: The present invention provides devices, systems, and methods for remotely alarming an intelligent hand held device when a sensor on a stair assist device is made thereby signaling an event which is of concern for a patient caregiver. In accordance with a first aspect of the invention, there is provided a remote transmitter for use with a smart phone or tablet connectable to sensors such as end of travel sensors for a stair climbing assist device or a mat, a photoelectric sensor, toilet or chair sensor and providing that information via wireless peer to peer communication to a smart phone or tablet so that a caregiver can react appropriately to the information. The remote transmitter device contains a conventional switch detection circuit and a peer to peer communications circuit such as Bluetooth.

Abstract: This invention relates to a stair assist apparatus for assisting individuals to move up or down stairs, ramps or inclined structures and is connected to a wireless communication system that can provide status and location of the apparatus or the individual using the apparatus to a remotely located caregiver. The wireless communication systems within this invention contains at least one transmitter and one receiver capable of communicating voice or analog or digital formatted information of the state of sensors incorporated into the stair assist device. The stair assist apparatus also provides a secure transition for the person at both the top and bottom of the stair or ramp so that they can make the last steps with the help of the assist of the apparatus.

Abstract: A wireless switch comprises a mechanical switch and a transmitter. The transmitter transmits information in the event that the mechanical switch is switched, wherein the transmitter is powered by the mechanical switch being switched.

Abstract: A wireless switch comprises a mechanical oscillator, a mechanical impulse deliverer, a first array of magnets positioned on a planar surface, a first conductor, and a power management circuit. The mechanical impulse deliverer delivers a mechanical impulse to the mechanical oscillator when the wireless switch is switched. The first array comprises a one dimensional or two dimensional array of magnets. The first conductor comprises a first serpentine conductor. The power management circuit provides DC power as a result of relative motion due to the mechanical oscillator between the first array of magnets and the first conductor.
