A fastener preferably made from a shape memory alloy is provided which can access internal tissue or other synthetic material by catheter delivery through an endovascular pathway. After the fastener is deployed through layers of tissue or other material, it assumes a shape that automatically applies to the layers of tissue or other material an appropriate hemostatic compression which is relatively independent of tissue or material thickness. The fastener is a suitable replacement for conventional non bio-absorbable sutures and staples in certain clinical applications. The shape, method of deployment, and low force requirements make the disclosed apparatus suitable for endosurgical procedures where access to the wound site is limited. A method for deploying the fastener is also provided.

A tethered unmanned aerial vehicle (“UAV”) may be outfitted with a sensor payload for data gathering. The tethered UAV may be tethered to a ground station for constricting the flight space of the UAV while also providing the option for power delivery and/or bidirectional communications. The tethered UAV's flight path may be extended by introducing one or more secondary UAVs that cooperate to extend the horizontal flight path of a primary UAV. The ground station, which may be coupled with the tethered aerial vehicle, may comprise a listening switch configured to determine a condition of the tether such that the supply of power to the tether may be terminated when tether damage or a tether severance is detected.

A method of promoting the healing of a lesion in a smooth muscle, comprising selecting a smooth muscle portion having a lesion and applying a non-excitatory electrical field to the portion, which field reduces the mechanical activity of the portion.

A barrier, such as a PV module, is secured to a base by a support to create a shingle assembly with a venting region defined between the barrier and base for temperature regulation. The first edge of one base may be interengageable with the second edge of an adjacent base to be capable of resisting first and second disengaging forces oriented perpendicular to the edges and along planes oriented parallel to and perpendicular to the base. A deflector may be used to help reduce wind uplift forces.

An aerodynamic golf club head incorporating a trip step feature located on the crown section. The benefits associated with the reduction in aerodynamic drag force associated with the trip step may be applied to drivers, fairway woods, and hybrid type golf club heads. The trip step is located between a crown apex and the back of the club head and may be continuous or discontinuous. The trip step enables a significant reduction in the aerodynamic drag force exerted on the golf club head by forcing the air passing over the club head from laminar flow to turbulent flow just before the natural separation point of the airstream from the crown. This selectively engineered transition from laminar to turbulent flow over the crown section slightly increases the skin friction but results in less aerodynamic drag than if the air were to detach from the crown section at the natural separation point.

The present invention provides a balloon catheter comprising: a hollow inner shaft disposed within a hollow outer shaft; a balloon attached at its proximal end to said outer shaft and at its distal end to said inner shaft; wherein the inner shaft is constructed such that following radial expansion of the balloon to a first expanded state, said inner shaft is capable of responding to further longitudinal expansion of the balloon to a second expanded state by increasing its length from a resting value, and of responding to subsequent partial deflation back to said first expanded state by reducing its length back to said resting value.

Disclosed are polyester shrink films comprising a voiding agent dispersed within a continuous polyester phase. The voiding agent comprises at least one first polymer and at least one second polymer, in which the polymer components have selected physical properties such as glass transition temperature, melting point, tensile modulus, surface tension, and melt viscosity. The resulting shrink films have high opacity, a low coefficient of friction, lower density, low shrink force, and good printability. The films are useful for sleeve label and other shrink film applications, and their lower density allows them to be readily separated from soft drink bottles, food containers and the like during recycling operations. Also disclosed is a process for separating a void-containing polyester from a mixture of polymers.

A low friction top coat over a multilayer metal/ceramic bondcoat provides a conductive substrate, such as a rotary tool, with wear resistance and corrosion resistance. The top coat further provides low friction and anti-stickiness as well as high compressive stress. The high compressive stress provided by the top coat protects against degradation of the tool due to abrasion and torsional and cyclic fatigue. Substrate temperature is strictly controlled during the coating process to preserve the bulk properties of the substrate and the coating. The described coating process is particularly useful when applied to shape memory alloys.

Apparatus for medical treatment or diagnosis in a body cavity of a mammalian subject includes an elongate probe, having an outer surface and comprising a distal portion, which is adapted for insertion into the body cavity. An electrode strip includes an elongate insulating substrate, which is wrapped around the distal portion of the probe so as to define a helix having distal and proximal ends and a length therebetween, the substrate being fixed to the outer surface of the probe over substantially all of the length of the helix. A plurality of electrodes are disposed along the length of the helix and fixed to the substrate. Electrical conductors are coupled to the electrodes and run along the substrate over the length of the helix so as to communicate with circuitry in a location proximal to the distal portion of the probe.

The present invention is a cosmetic or dermatological preparation for use with a dispenser that includes an auxiliary to keep the dispenser operating smoothly. The auxiliary is selected from the group consisting of (i) polyols having 2 to 6 carbon atoms and 2 to 6 hydroxyl or alkoxy groups and (ii) surfactants that reduce the surface tension of the preparation to less than 30 mN/m. The preparation is particularly suitable with a dispenser comprising a container and an inner container wall for housing a cosmetic or dermatological preparation; a follow-up plunger on a base side of the dispenser, which is capable of being slidably displaced on the inner container wall under the pressure of the ambient atmosphere; a head section on a top end of the dispenser that can be slidably displaced in relation to the container and that comprises a dispensing channel, the dispensing channel capable of being connected in a communicating manner to the container; a manually actuable delivery device comprising a variable-volume delivery chamber, a delivery element that can be displaced longitudinally in relation to the container and the head section, comprising a delivery plunger that can be slidably displaced within the delivery chamber and a delivery stem connected to the delivery plunger, and a delivery channel circumferentially enclosed by the delivery stem and comprising a delivery-channel inlet opening communicating with the delivery chamber and a delivery-channel outlet opening. The delivery channel outlet opening is capable of being moved into an open position relative to the dispensing channel by displacing the delivery element.
