Abstract: The present invention relates to a solid formulation of soap stick type comprising a primary surfactant, at least one binding agent and at least one dispersant that may especially be an amphoteric surfactant, optionally with additives. The present invention also relates to uses of said formulation, especially for oilfield applications, e.g. for gas well deliquification applications.

Abstract: A leadless cardiac pacemaker (LCP) that is configured for atrial placement may include a housing, two or more electrodes and a controller that is disposed within the housing and that is operably coupled to the two or more electrodes. The controller may be configured to sense activation of the atrium of the patient's heart via two or more of the electrodes and to deliver pacing therapy via two or more of the electrodes to a ventricle of the patient's heart by pacing the bundle of His in the patient's atrioventricular septum.

Abstract: A leadless pacing device may include a housing having a proximal end and a distal end, and a set of one or more electrodes supported by the housing. The housing may include a first a distal extension extending distally from the distal end thereof. The distal extension may include a retractable and/or rotatable distal electrode. The distal electrode may be configured to be delivered to and pace at the Bundle of His. The leadless pacing device may be releasably coupled to an expandable anchor mechanism.

Abstract: Implantable medical devices such as leadless cardiac pacemakers (LCP) may be configured to be delivered to a target location within the heart over a guide wire. In some cases, using a guide wire for delivery facilitates placement of devices in regions not otherwise easily reached. An LCP may include a housing and a wire lumen disposed relative to the housing. The wire lumen may be configured to allow the LCP to slide over a guide wire. In some cases, the guide wire may include a guide wire electrode that may be used to test potential implantation sites.

Abstract: A process for simultaneously dissolving iron sulphide and killing or inhibiting bacteria comprising the steps of continuously adding or shot dosing to a hydrocarbon-containing system, an aqueous fluid comprising a formulation comprising tris(hydroxymethyl) phosphine or tetrakis (hydroxymethyl) phosphonium salt.

Abstract: A system for sensing electrical cardiac activity and for providing therapy to a patient's heart. The system may include a first implantable device implanted within a patient and a second implantable device implanted near or within the heart of the patient. In some cases, the first implantable device may at least partially power the second implantable device by periodically recharging a rechargeable battery or other power source within the second implantable device. In some cases, the first implantable device may at least partially power the second implantable device by periodically, intermittently or continuously transmitting energy that may be stored by a battery, capacitor or other power storage device within the second implantable device.

Abstract: A leadless cardiac pacemaker (LCP) may be deployed within a patient's vasculature at a location near the patient's heart in order to pace the patient's heart and/or to sense electrical activity within the patient's heart. In some cases, an LCP may be implanted within the patient's superior vena cava or inferior vena cava. The LCP may include an expandable anchoring mechanism configured to secure the LCP in place.

Abstract: An implantable medical device may include a housing configured to be positioned at least in part in a right ventricle (RV) proximate an RV facing side of the ventricular septum. A power source and circuitry may be disposed within the housing and may be operatively coupled together. An RV electrode may be fixed relative to the housing to be proximate the RV facing side of the ventricular septum and may be operatively coupled with the circuitry. An LV electrode support may extend away from the housing into the ventricular septum toward the LV facing side of the ventricular septum and may support an LV electrode that is operatively coupled with the circuitry. The circuitry may be configured to pace the RV of the patient's heart using the RV electrode and to pace the LV of the patient's heart using the LV electrode.

Abstract: Example apparatus and methods concern detecting and responding to a multiple hover point gesture performed for a hover-sensitive device. An example apparatus may include a hover-sensitive input/output interface configured to detect multiple objects in a hover-space associated with the hover-sensitive input/output interface. The apparatus may include logics configured to identify an object in the hover-space, to characterize an object in the hover-space, to track an object in the hover-space, to identify a multiple hover point gesture based on the identification, characterization, and tracking, and to control a device, application, interface, or object based on the multiple hover point gesture. In different embodiments, multiple hover point gestures may be performed in one, two, three, or four dimensions. In one embodiment, the apparatus may be event driven with respect to handling gestures.

Abstract: Example apparatus and methods concern detecting and responding to a crane gesture performed for a touch or hover-sensitive device. An example apparatus may include a hover-sensitive input/output interface configured to display an object that can be manipulated using a crane gesture. The apparatus may include a proximity detector configured to detect an object in a hover-space associated with the hover-sensitive input/output interface. The apparatus may include fogies configured to change a state of the object from untouched to target to pinched to lifted to released in response to detecting the appearance and movement of bracket points. The appearance of the object may change in response to detecting the state changes.
