A tissue collection device () for collection of one or more exposed tissue samples () from a biopsy needle or biopsy device, which tissue collection device comprises one or more pieces of a carrier medium () and is arranged to temporarily bring a piece of carrier medium into physical contact with the tissue sample, while the tissue sample is still positioned in the biopsy needle or biopsy device, so that the tissue sample () adheres to the carrier medium () and is removed from the biopsy needle () or biopsy device () with the carrier medium (), when the carrier medium () is removed from the biopsy needle or biopsy device again. Furthermore, a biopsy device comprising such a tissue collection device is disclosed.

Tissue collection device for collection of one or more tissue samples from a biopsy needle or biopsy device and biopsy device comprising such a tissue collection device

An endoscopic biopsy device for collecting samples. The device includes a tubular body having distal and proximal ends and jaws hinged to the distal end. The jaws operate between OPEN and CLOSED positions to secure a tissue sample. In the CLOSED position, the jaws define a sampling chamber. A collecting chamber for receiving samples is located within the body near the sampling chamber. A collecting member for transfixing secured samples is displaceable between a retracted position in the collecting chamber and a deployed position where the collecting member penetrates into the sampling chamber. The jaws include retaining elements projecting inwardly on a portion of the jaws. The retaining elements engage when the jaws are CLOSED, separating the sampling and collecting chambers from each other. The retaining elements disengage when the jaws are OPEN, providing a passage for the transfer of transfixed samples into and out of the collecting chamber.

Endoscopic device for multiple sample biopsy

Gas turbine unit comprising a high pressure turbine (10) driving a high pressure compressor (11), and a low pressure turbine (13) driving a low pressure compressor (14) and a generator (12), a combustion chamber supplying gas to the compressors, and a recuperator (18) for heat exchange between exhaust gas and compressor air, the low pressure turbine having an adjustable geometry and an adjustable connection (20) being provided bypassing the recuperator, and a method in operating the gas turbine unit wherein the electrical power is adjusted to a desired value by changing the geometry of the low pressure turbine and the heat power is adjusted by adjusting the bypass flow to a desired value.

Method for operating gas turbine unit for combined production of

The invention relates to a method of operating a gas turbine unit comprising a combustion chamber, a high pressure turbine driven by gas from the combustion chamber, and a low pressure turbine driven by gas from the high pressure turbine, means for controlling the gas supply from the high pressure turbine to the low pressure turbine, and a low pressure compressor driven by the low pressure turbine, and a high pressure compressor connected in series with the low pressure compressor and driven by the high pressure turbine for supplying pressurized air to the combustion chamber, the useful power of the gas turbine unit being adjustable by controlling the gas condition upstream of the low pressure turbine by the control means. Substantially all the air delivered to the combustion chamber from the compressors, is utilized for the combustion in the combustion chamber. The generated gas is cooled with water and/or steam to a temperature which corresponds to the maximum operating temperature of the high pressure turbine. Use is made of the power obtained from the combustion chamber by cooling, and the useful power of the gas turbine unit is recovered from the high pressure turbine at substantially constant rotational speed thereof. The temperature of the gas supplied to the high pressure turbine is maintained substantially constant independently of the useful power recovered from the gas turbine unit.
