A glucose sensor in the form of a skin patch 2 has a microneedle 4 which painlessly penetrates the skin to draw out interstitial fluid. The interstitial fluid passes to a common entrance port 7. A series of microchannels 8 is provided on the skin patch. The fluid drawn onto the patch is selectively switched between a number of microchannels 8 by means of electro-osmotic pumps 10 and hydrophobic gates 12. Each microchannel 8 has an electrochemical detector 11 for sensing gluocse concentration. Also disclosed is a monlithic device with an integrated lance 83.

Described are devices, methods, and kits for non-invasively measuring glucose. In general, the devices comprise skin patches for placement on a skin surface and measurement devices for measuring glucose collected in the patches. The patches may include an adhesive material, a collection layer, an interface layer, and a sweat-permeable membrane. The sweat-permeable membrane is configured to act as a barrier to epidermal contaminants and glucose brought to the skin surface via diffusion. In this way, non-correlatable skin surface glucose will not be measured. The patches may further include components to induce a local sweat response. The measurement device typically includes a display, a processor, and a measurement mechanism. The methods typically include the steps of wiping the skin surface with a wipe containing at least one solvent for removing glucose, placing a patch on a skin surface, and measuring glucose collected in the patch. Kits comprising the patch and measurement device are also described.

A catheter and patch electrode system is provided for use with an apparatus, such as an ablation generator, having a 4-wire interface for improved impedance measurement. The 4-wire interface includes a pair of source connectors across which an excitation signal is produced and a pair of sense connector wires across which the impedance is measured. The RF ablation generator may also produce an ablation signal across a source wire and an indifferent return patch electrode. The system further includes a cable that connects the generator to a catheter. The catheter includes a shaft having a proximal end and a distal end, with an ablation tip electrode disposed at the distal end. A source lead is electrically coupled to the tip electrode and extends through the shaft to the proximal end where it is terminated. An optional sense lead is also electrically coupled to the tip electrode and extends through the shaft to the proximal end. The system further includes a source return (e.g., skin patch) and a sense return (e.g., skin patch), either or none of which may be combined with the indifferent return, and if used may be placed on opposite sides of the patient for improved performance. The impedance sensor circuit produces an excitation signal across the source connectors, which is then carried to the catheter by the cable, then to the tip electrode, travels through the complex load (tissue volume), and returns to the generator via a patch electrode. The impedance is measured by observing the voltage drop across the sense connectors caused by the excitation signal.

The present invention generally relates to systems and methods for determining oxygen in a sample, or in a subject. In one aspect, the present invention is generally directed to an article exhibiting a determinable feature responsive to oxygen, such as oxygen-sensitive particles. The particles may exhibit a determinable change with a change in oxygen concentration, and such particles can accordingly be used to determine oxygen. For example, in one set of embodiments, the particles may be at least partially coated with a protein, such as hemoglobin, that is able to interact with oxygen. In some cases, the protein may aggregate under certain conditions (e.g., under relatively low oxygen concentrations), and such protein aggregation may be used, for example, to cause the particles to become aggregated, which can be determined in some way. In some cases, such aggregation may be irreversible; i.e., the degree of aggregation corresponds to the most extreme oxygen concentrations that the proteins were exposed to. Such articles may be used, for example, to determine oxygen within a sample, or within a subject, such as a human subject. For instance, the article may be formed as a skin patch, or administered to the skin of a subject, e.g., on the surface of the skin, within the dermis or epidermis, etc., to determine oxygen within the subject.

Marker compounds indicative of variations in physiological conditions, genetic defects or disease states have been found to be present in apocrine sweat and, in many conditions, these markers are present in apocrine sweat in elevated levels when compared to blood. These markers are collected and / or detected in apocrine sweat and used as an indicator that a disease state or particular physiological condition exists. A skin patch, wipe or other collection means is used to collect apocrine sweat. The apocrine sweat is then used to indicate the existence of a disease state or changing physiological condition by the presence of specific marker compounds. Apocrine sweat can also be collected from individuals known to have a specific disease or physiological condition and, by comparison with apocrine sweat from normal individuals, used to identify new markers indicative of the specific disease state or physiological condition.
