Abstract: A guidewire for intravascular procedures is provided. The guidewire may include a guidewire shaft and a distal end. The guidewire shaft may include a proximal shaft portion that is substantially straight and an intermediate portion integral with or connected to the proximal shaft portion. The intermediate portion may have a meandering shape in at least one first plane. The distal end may be connected to the intermediate portion of the guidewire shaft and have a curved shape in a second plane different from the at least one first plane of the meandering shape of the intermediate portion.

Abstract: A power tool is provided that includes a tool carrier for mounting an impact tool. The tool carrier has a base member aligned with an operational axis. The base member has a head end for receiving impact energy, a foot end provided with a tool mount configured to transmit the impact energy to the impact tool, and a casing engagement feature between the head end and foot end. A first casing module is provided with a tool carrier engagement feature complementary in shape to, and for interlocking engagement with, the tool carrier casing engagement feature to prevent rotation of the tool carrier relative to the first casing module around the operational axis, and permits relative movement between the tool carrier and the first casing module along the operational axis.

Abstract: According to various embodiments, systems, devices and methods for modulating targeted nerve fibers (e.g., hepatic neuromodulation) or other tissue are provided. The systems may be configured to access tortuous anatomy of or adjacent hepatic vasculature. The systems may be configured to target nerves surrounding (e.g., within adventitia of or within perivascular space of) an artery or other blood vessel, such as the common hepatic artery.

Abstract: A method of digital sampling of a current or group of currents in an electrical system including using in the sampling, sufficient bandwidth to reconstruct the amplitude and phase of a synthesized power frequency and its harmonics and a fundamental carrier frequency of switching electronics and modulation sidebands.

Abstract: Techniques are provided for a metasearch infrastructure. The metasearch infrastructure supports one or more of the following: hotel matching, backend support of user queries, frontend support for user queries, a cache layer that groups or organizes cached data in storage based on hotel location, scoring and ranking on the client side, experiments and rankers, duplicate booking prevention, blacklisting hotels, and indexing that utilizes a document-independent data structure to store index values.

Abstract: A bifurcation stent (1) having a closed terminus (4) and two angled apertures (5, 6) at its distal end (3). The bifurcation stent may be a balloon-inflated stent, or a self-expanding stent. The delivery systems for the stent employ a guide wire through each aperture of the stent.
