A novel suture removal instrument, kit and technique are described herein. The invention utilizes a newly designed thermal filament to allow the tip of the suture removal instrument to be slipped under the stitch in order to heat and cut the stitch. Current suture removal techniques utilize scissors, forceps, and / or scalpels. These techniques, which are well known in the art, are problematic because they exert tension on the stitch and are associated with patient discomfort. Small stitches add to the difficulty of suture removal because they have less suture laxity for scissor insertion. The present invention therefore allows for more rapid suture removal with less patient discomfort and at a competitive or lower cost.

A method and apparatus of treating tissue adjacent to a bodily conduit using thermotherapy, while preventing obstructions of the bodily conduit due to edema employs the circulation of warmed fluid to maintain the temperature of the bodily conduit walls and compresses the tissue to be treated to increase the effectiveness of the irradiated heat. An energy-emitting source containing catheter is inserted in a bodily conduit and is positioned in a region of the tissue to be treated so that the energy-emitting source radiates energy to the tissue to be treated. Fluid warmed to over 30° C. is circulated into and through the catheter to warm walls of the bodily conduit adjacent the catheter. The circulated fluid inflates a balloon to a pressure to compress the tissue to be treated. The combination of warmed fluid over 30° C. being circulated adjacent the bodily conduit to maintain the warmth in its walls and the compression of the tissue to be treated enables a natural stent to be formed that remains after the catheter and compression balloon is removed.

A laser processing apparatus which can suppress the positional fluctuation in light-converging point of laser light during laser processing is provided. On an optical path of laser light L1 connecting a beam expander 34 and a first light-transmitting hole 32 of a lens holder 29 to each other in a laser processing apparatus 20, a stop member 38 including a second light-transmitting hole 39 having the same diameter as that of the first light-transmitting hole 32 is disposed. Hence, the amount of laser light L1 cut by the surrounding part of the first light-transmitting hole 32 can substantially be eliminated, whereby the lens holder 29 can be prevented from being heated upon irradiation with the laser light L1. Also, even when the stop member 38 is heated by the laser light L1 cut by the surrounding part of the second light-transmitting hole 39, heat is prevented from being transmitted from the stop member 38 to the lens holder 29, since the stop member 38 is separated from the lens holder 29. Therefore, the positional fluctuation in light-converging point P1 of the laser light L1 during laser processing can be suppressed to a low level.

It also facilitates the replacement of the protective lens of the camera.

A drive unit which uses an electric motor as a power source and has an integrated inverter, with a cooling circuit for the electric motor and the inverter. The drive unit includes a drive unit case, the electric motor housed within the case, and the inverter fixed to the case. A coolant flow passage is provided between the drive unit case and the inverter. The inverter is fixed to the drive unit case through a panel wall, and a partition divides the coolant flow passage into chambers which are coextensive in parallel. As a result, the coolant which flows through the coolant flow passage acts as a two-stage heat shield, barring the heat generated by the electric motor from being transmitted to the inverter.

An expansion joint seal system which includes intumescent to protect uncoated edges of substrates. A fire rated compressed expansion joint sealant is provided having an intumescent proximate, but below the water-resistant top of the fire-retardant foam, so that when exposed to fire, the intumescent expands to protect the exposed vertical surface of the adjacent concrete substrate. The end of the concrete is therefore protected in a manner which does not require joint overlap between the horizontal fire resistant coating and the compressible sealant.

A pressure wave generator is provided, which has excellent output stability over time. This pressure wave generator comprises a substrate, a heat generating layer, and a heat insulating layer formed between the substrate and the heat generating layer. A pressure wave is generated in a surrounding medium (air) by a change in temperature of the heat generating layer, which is caused upon energization of the heat generating layer. The heat insulating layer comprises a porous layer and a barrier layer formed between the porous layer and the heat generating layer to prevent diffusion of reactive substances such as oxygen and moisture in the air and impurities into the porous layer. By the formation of the barrier layer, it is possible to prevent a reduction in output of the pressure wave generator caused by a change over time of the porous layer.

A motor vehicle dehumidifier, including a dehumidifying drying agent, that can provide a required dehumidifying capacity with a reduced overall quantity of drying agent compared to conventional drying agent-based dehumidifiers. In the present invention, a heat exchanger is disposed on an upstream side of a drying agent unit, and heat is exchanged in the heat exchanger between inside air to be dehumidified and low-temperature outside air used to cool the inside air. The air cooled by the heat exchanger flows into the drying agent unit and is dehumidified. Because the air has an increased relative humidity as a result of being cooled, the amount of water adsorbed from it per unit of drying agent is increased, as the water adsorption characteristic of the drying agent is greatly influenced by the relative humidity of the air passing over it, and is markedly improved by an increase in the relative humidity of that air.

A well treating composition containing a polysaccharide-based water-superabsorbent material has particularly applicability as a thermal insulating, fracturing or acid stimulation fluid. The water-superabsorbent material is capable of absorbing, at a minimum, its own weight. Particularly effective are biodegradable materials containing guar gum and carrageenan. The composition may further contain a crosslinking agent, brine and / or a viscosifying polymer or a gelling agent. As an oil-based fluid, the crosslinking agent is absorbed onto the water-superabsorbent material and serves to effectively delay crosslinking.

A hair curling iron that forms spiral curls having an integral vacuum system and an internal heating tube is designed to eliminate the need for manual rotation of the entire curling iron when forming spiral hair curls. The curling iron provides a slot into which the hair is pulled by an integral vacuum fan mounted within the handle and controlled by an on / off pushbutton. When activated, the vacuum fan pulls the hair into the curling iron and around an interior heating tube. After several seconds, the pushbutton is released and a spiral curl is pulled out of the curling iron. A separate illuminating switch provides control of the heating portion of the curling iron. The danger of accidental burns is greatly reduced due to the interior location of the hot surfaces.
