Methods, systems and devices are described for new modes of ventilation in which specific lung areas are ventilated with an indwelling trans-tracheobronchial catheter for the purpose of improving ventilation and reducing hyperinflation in that specific lung area, and for redistributing inspired air to other healthier lung areas, for treating respiratory disorders such as COPD, ARDS, SARS, CF, and TB. Trans-Tracheobronchial Segmental Ventilation (TTSV) is performed on either a naturally breathing or a mechanical ventilated patient by placing a uniquely configured indwelling catheter into a bronchus of a poorly ventilated specific lung area and providing direct ventilation to that area. The catheter can be left in place for extended periods without clinician attendance or vigilance. Ventilation includes delivery of respiratory gases, therapuetic gases or agents and evacuation of stagnant gases, mixed gases or waste fluids. Typically the catheter's distal tip is anchored without occluding the bronchus but optionally may intermittently or continuously occlude the bronchus. TTSV is optionally performed by insufflation only of the area, or by application of vacuum to the area, can include elevating or reducing the pressure in the targeted area to facilitate stagnant gas removal, or can include blocking the area to divert inspired gas to better functioning areas.

A sternum closure device for securing parts of severed sternum, such as a human sternum following surgery. The device includes an anvil, capable of forming staples, a bracket positioned, opposite the anvil, an instrument for creating openings in the sternum a clamping mechanism and a mechanism for feeding, mounting and applying the staples. The bracket is joined with the anvil through a displacement mechanism. The instrument for forming opening is designed as a bit brace having a reducing gear and two chucks, to enable concurrent drilling of openings in both severed parts of the severed sternum. The mechanism for feeding and mounting the staples comprises a ribbed bed, a cartridge containing staples and an instrument for mounting the staples. The clamping means enables drilling of openings in both severed parts of sternum, and feeding and mount the stables. Specially designed pincers are also provided for mounting the staples and other special staples.

Building panels, such as floorboards, provided with a mechanical locking system. The mechanical locking system includes a displacement groove at a first edge of a first floorboard and a tongue groove at a second edge of a second floorboard A tongue is arranged in the displacement groove and is configured to cooperate, in a second position, with the tongue groove for vertical locking of the first and the second edge. The tongue includes, in a first position, an inner element and an outer element. The inner element is removable along the displacement groove, and is configured to cooperate with the outer element to obtain a displacement of the outer element towards the tongue groove and thereby obtain the second position. Said inner element and said outer element vertically overlap each other.

A method of running a bore-lining tubing string into a bore includes running a tubing string, typically a liner string, into a bore while agitating the string. The agitation of the string reduces the friction between the string and the bore wall and thus facilitates the translation of the string into the bore. The agitation may also take place while the tubing is being cemented in the bore. Pressure pulses may be applied to fluid in the bore, which fluid may be cement slurry.

PCT No. PCT/EP96/04131 Sec. 371 Date May 14, 1998 Sec. 102(e) Date May 14, 1998 PCT Filed Sep. 21, 1996 PCT Pub. No. WO97/18432 PCT Pub. Date May 22, 1997The invention discloses a compressed gas-operated pistol (1) with a gas capsule (15) arranged in a grip member (5), which is in operative connection with a valve system (33) of the pistol (1). The secure receipt and piercing of the gas capsule (15) is effected through an abutment (17) which completes an inherent displacement and an external displacement superimposed on this inherent displacement. The external displacement is thereby effected by a support element (23) of the abutment (17) which is contacted by capsule tensioner (25). (FIG. 2).

The riser is movable through an opening in the rig floor, and a surface flow head connected to the riser and to a wire line or coiled tubing equipment. The surface flow head is arranged to be run through the opening in the rig floor.

Chemical etching methods and associated modules for performing the removal of metal from the edge bevel region of a semiconductor wafer are described. The methods and systems provide the thin layer of pre-rinsing liquid before applying etchant at the edge bevel region of the wafer. The etchant is less diluted and diffuses faster through a thinned layer of rinsing liquid. An edge bevel removal embodiment involving that is particularly effective at reducing process time, narrowing the metal taper and allowing for subsequent chemical mechanical polishing, is disclosed.

A multiblade knife unit includes knife blades of different type normally stored within and adapted for deployment from a common end of a handle housing. A pivoting knife blade is supported for pivotal movement between a stored position nested substantially within one side edge of the handle housing, and a deployed position projecting from one end of the handle housing. A razor-type utility knife blade is supported by a slide clip for sliding displacement between a retracted position stored and concealed within the handle housing, and an advanced position projecting from said one end of the handle housing. A release button on the handle housing is depressed for releasing the utility knife blade from the slide clip for facilitating quick and easy slide-out blade removal and replacement. In one form, the knife unit may further include driver bits interchangeably mounted at an opposite end of the handle housing.
