US Classification:

604263, 600347

Abstract:

An introducer is provided for introducing a sensor into the body of a patient. The introducer connects to a sensor hub.

US Classification:

600347, 324 711, 174116, 29874

Abstract:

A multiple-conductor electrical lead for use with medical device systems and a method of manufacture is disclosed. The multiple-conductor electrical lead comprises a central core and has at least one conductor, typically in the form of a ribbon cable, coiled around it along its length. Typically one or more ribbon cables coiled around a central core each comprise a plurality of separate electrical conductors both coupled together along their lengths in series and electrically insulated from one another with an insulating material. The material of the central core, e.g. polyester, stainless steel, nickel titanium, and the structural configuration, e.g. wrapping pitch of the ribbon cable around the central core and number of ribbon cables, are selected based on desired mechanical characteristics. Such multiple-conductor electrical leads are useful, for example, with analyte sensor systems such as amperometric glucose sensor systems used in the management of diabetes.

International Classification:

A61B 5/145

US Classification:

600347, 600345

Abstract:

Embodiments of the invention provide a dual insertion set for supplying a fluid to the body of a patient and for monitoring a body characteristic of the patient. Typical embodiments of the invention include a base, an infusion portion coupled to a first piercing member and a sensor portion coupled to a second piercing member. The infusion portion includes a cannula coupled to the piercing member for supplying a fluid to a placement site. The sensor portion includes a sensor coupled to and extending from the base having at least one sensor electrode formed on a substrate and is coupled to the piercing member in a manner that allows the sensor to be inserted at the placement site. The base is arranged to secure the dual insertion set to the skin of a patient. Typically the infusion portion and sensor portion piercing members are arranged such that when they are operatively coupled to the base, they are disposed in a spatial orientation designed to inhibit sensor interference that may be caused by compounds present in fluids infused through the cannula.

Abstract:

A continuous glucose monitoring system may include a hand-held monitor, a transmitter, an insulin pump, and an orthogonally redundant glucose sensor, which may comprise an optical glucose sensor and a non-optical glucose sensor. The former may be a fiber optical sensor, including a competitive glucose binding affinity assay with a glucose analog and a fluorophore-labeled glucose receptor, which is interrogated by an optical interrogating system, e.g., a stacked planar integrated optical system. The non-optical sensor may be an electrochemical sensor having a plurality of electrodes distributed along the length thereof. Proximal portions of the optical and electrochemical sensors may be housed inside the transmitter and operationally coupled with instrumentation for, e.g., receiving signals from the sensors, converting to respective glucose values, and communicating the glucose values. The sensors' distal portions may be inserted into a user's body via a single delivery needle and may be co-located inside the user's body.
