Smart recognition apparatus and method

A qualifying connection for an instrument attaches to a source of electrosurgery energy to and the instrument and has first and second parts coupled to the instrument and the source, respectively. Optical couplings on the connection transmit invisible energy to identify the instrument and are proximate on the first and second parts. A light modifier on the first part is proximal to the second part for modification of radiation in the infrared wavelengths so infrared transmitters encode signals and non contact coded proximity detectors on the second part are the coupled detectors. Non contact coded proximity detectors respond to modified infrared light establishing an Nth bit identification code. An infrared light supply in the source pass from the transmitters across the communicating couplings for encoding signals by modification of the infrared light with a light modifier. Mechanical attachments include conjugating male and female portions physically extending between the parts for mating engagement. The attachments juxtaposition the parts when the attachments geometrically conjugate to geographically positioning the couplings proximate for communicating. The attachments have one or more conductors for delivery of high frequency energy from the source to the instrument. A cable fits between the first part of the connection and the instrument and has electrical conductors for carrying energy passing through the first part of the connection from the source to the instrument. An identifying circuit couples to the second part and responds to invisible light optically communicated across the couplings for verifying the type of instrument connected by the cable to the source.

Integrated delivery device for continuous glucose sensor

Abstract of the DisclosureSystems and methods for integrating a continuous glucose sensor, including a receiver, a medicament delivery device, and optionally a single point glucose monitor are provided. Manual integrations provide for a physical association between the devices wherein a user (for example, patient or doctor) manually selects the amount, type, and / or time of delivery. Semi-automated integration of the devices includes integrations wherein an operable connection between the integrated components aids the user (for example, patient or doctor) in selecting, inputting, calculating, or validating the amount, type, or time of medicament delivery of glucose values, for example, by transmitting data to another component and thereby reducing the amount of user input required. Automated integration between the devices includes integrations wherein an operable connection between the integrated components provides for full control of the system without required user interaction.

Electric treatment system

A treatment tool for performing a treatment for a curative procedure with ultrasonic waves, high frequency current and so on is provided with an identifier formed of a resistor or the like for indicating the type of the treatment tool. A medical instrument such as an ultrasonic wave output apparatus discriminates the type of a treatment tool connected thereto from the identifier to automatically set operating parameters such as an output value suitable for the treatment tool and to associatively operate an ancillary medical instrument such as a perfusion / aspiration apparatus depending on the treatment tool, thereby reducing extra work such as manual setting to allow for a smooth treatment.

Medical devices with enhanced ultrasonic visibilty

A medical device having enhanced ultrasonic visibility is provided. The device permits localized drug delivery, probe positioning, fluid drainage, biopsy, or ultrasound pulse delivery, through the real-time ultrasound monitoring of the needle tip position within a patient. The device permits controlled dispersion of a drug into solid tissue, the lodging of particles into solid tissue, and drug delivery into specific blood vessels. As a needle is inserted, a fluid that contrasts echogenically with the organ environment is injected into the patient. The fluid travels a brief distance before being slowed and stopped by the patient's tissue and this fluid flow will be detectable by ultrasound. The needle position during insertion will be monitored using ultrasound until it is at the desired point of action. A therapeutic drug is then delivered or a probe inserted
