Abstract:
A system and associated method measure monophasic action potential signals for identifying a targeted tissue location and delivering a therapy to the targeted tissue location. The system includes a hollow needle having a sharpened distal tip, a first electrode at the distal tip and a fluid delivery lumen extending through the needle from a proximal needle end to an opening in the sharpened distal tip.
Abstract:
Device, system and method for evaluating the effectiveness of tissue ablations of a heart of a patient. The tissue is clamped between a pair of opposing jaws. A portion of the tissue is ablated at a first generally linear position on the tissue by applying ablative energy to two of a plurality of elongate electrodes, each of the two of the plurality of elongate electrodes being coupled in opposing relationship to each other and the pair of opposing jaws, respectively. An effectiveness of the ablation is sensed at a second generally linear position on the tissue with at least one of the plurality of elongate electrodes positioned on one of the pair of opposing jaws. The second linear position on the tissue is laterally distal to the first linear position on the tissue with respect to the atrium of the heart.

Abstract:
The present invention pertains generally to the field of therapeutic compounds, and more specifically to certain pyruvamide compounds of the formula (X) (for convenience, collectively referred to herein as "PVA compounds"), which, inter alia, inhibit a dust mite Group 1 peptidase allergen (e.g., Der p 1, Der f 1, Eur m 1). The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo , to inhibit a dust mite Group 1 peptidase allergen, and in the treatment of diseases and disorders that are mediated by a dust mite Group 1 peptidase allergen; that are ameliorated by the inhibition of a dust mite Group 1 peptidase allergen; asthma; rhinitis; allergic conjunctivitis; atopic dermatitis; an allergic condition which is triggered by dust mites; an allergic condition which is triggered by a dust mite Group 1 peptidase allergen; and canine atopy.

Abstract:
Catheters and methods for obtaining monophasic action potential ("MAP") electrograms include a flexible catheter body defining a longitudinal axis, and a distal assembly affixed to the catheter body distal end defining a distal tip. The distal assembly has at least three MAP recording electrodes, and at least one reference electrode for determining reference potential. The recording electrodes are each positioned a radial distance from the longitudinal axis in at least three different radial directions, defining a recording geometry substantially having radial symmetry. The reference electrode is a longitudinal distance from the recording geometry. Optional features include a steerable catheter shaft, one or more radio-frequency ablation electrodes, and a dedicated pacing electrode. Different possible embodiments include a dome housing having the recording electrodes in a fixed spatial arrangement, and a distal loop assembly having an array of electrodes on at least three flexible loop elements.
Abstract:
A process to prepare an olefin from its corresponding alcohol is improved by reacting, under reaction conditions including a first temperature, an aliphatic alcohol and, optionally, diluent water, to form a reaction product including at least a dialkyl ether. The product is then reacted again, under higher temperature to complete the dehydration of the dialkyl ether to the desired olefin. This process is particularly suitable to prepare ethene from ethyl alcohol. The stepped temperature scheme serves to reduce the formation of byproduct aldehydes, which in turn reduces coke formation, fouling, and the need to handle large amounts of water, thereby lowering energy and capital costs.
Abstract:
A PIN-entry device (PED) stand (27) includes a data interface whereby the stand may be connected to an EFT card payment system (10) for transmitting and/or receiving data to and/or from the EFT card payment system independently of a PED (18) mounted on the stand. The stand further includes any one or more of the following, in communication with the data interface: a data input device such as a contactless card reader ( 36) or a biometric devicefor receiving information for processing a card transaction and/or for management of the payment system; at least one further data interface whereby the stand may be connected to a peripheral device; a secure memory device for storing a secret key for use in an authentication system. Software of the EFT card payment system drivesa display (24) of a PED (18) installed on the PED (27) stand and connected to the payment system (10) in order to display information relating to functions associated with the data input device, further data interface and/or peripheral device connected thereto, and/or secure memory device of the PED stand.
