20100076341 | CANNULA PROVIDED WITH A SEALING ELEMENT FOR USE IN A MEDICAL PROCEDURE - A cannula arrangement includes an outer tube and an inner tube. The outer tube has a proximal end and a distal end. The inner tube is disposed within the outer tube to define a space between an inner surface of the outer tube and an outer surface of the inner tube. A sealing element is mounted at the proximal end of the outer tube. The sealing element has a projecting portion that projects proximally from the proximal end of the outer tube. The projecting portion has a projecting end that has an interior edge to contact the outer surface of the inner tube. | 03-25-2010 |
20110021946 | BIOPSY NEEDLE SYSTEM HAVING A PRESSURE GENERATING UNIT - A biopsy needle system includes a cylinder with an open end and a cylinder wall. A piston is inserted in the open end such that a cylinder interior volume is defined between the piston and the cylinder, the piston being movable in the cylinder. A biopsy needle is connected to the cylinder. A ventilation groove is established in the cylinder wall only to a depth of a portion of a thickness of the cylinder wall. The ventilation groove is positioned such that the cylinder interior volume of the cylinder communicates with the ambient atmosphere when the piston is displaced to a position in the cylinder so as to establish an airflow through the ventilation groove past the piston. | 01-27-2011 |
20120203135 | BIOPSY NEEDLE SYSTEM HAVING A PRESSURE GENERATING UNIT - A biopsy needle system includes a cylinder with a fluid connection end, an open end and a cylinder wall. A piston is coupled to a threaded spindle shaft. The threaded spindle shaft is configured to extend from the piston and through the open end of the cylinder. The piston is inserted in the open end such that a cylinder interior volume is defined between the piston and the fluid connection end. A spindle nut is mounted to the open end of the cylinder. The spindle nut is threadably engaged with the threaded spindle shaft and configured to displace the piston via a linear translation of the threaded spindle shaft when the spindle nut is rotated. A biopsy needle is connected in fluid communication with the fluid connection end of the cylinder. | 08-09-2012 |

20100106055 | BIOPSY DEVICE HAVING A VACUUM PUMP - A biopsy device includes a housing. A drive is enclosed in the housing. A biopsy needle assembly has a biopsy needle carrier that carries a biopsy needle. The biopsy needle carrier is positioned in the housing. A vacuum pump is positioned in the housing. The vacuum pump has an elongate cylinder and a piston sealed and movable inside the elongate cylinder. The piston is drivably coupled to the drive. The elongate cylinder is connected to the biopsy needle to generate a vacuum in the biopsy needle when the piston is driven by the drive. The elongate cylinder and the biopsy needle are arranged in parallel by the housing. | 04-29-2010 |
20120095366 | DISPOSABLE BIOPSY UNIT - A disposable biopsy unit includes a biopsy needle unit and a pump. The biopsy needle unit includes a carrier, a biopsy needle and a cutting sheath. The carrier is configured to mount the biopsy needle and the cutting sheath. The cutting sheath is configured to move along a longitudinal axis relative to the biopsy needle. The pump has an elongate cylinder and a plunger. The plunger is configured to be movable inside the elongate cylinder in a first direction from a distal end of the elongate cylinder to a proximal end of the elongate cylinder to generate a vacuum and configured to be movable inside the elongate cylinder in a second direction from the proximal end of the elongate cylinder to the distal end of the elongate cylinder to build up pressure. The distal end of the elongate cylinder is coupled in fluid communication with the biopsy needle. | 04-19-2012 |
20120238905 | BIOPSY DEVICE AND INSERTABLE BIOPSY NEEDLE MODULE - A biopsy device includes a disposable unit including a needle carrier and a biopsy needle. The biopsy needle has a distal portion including a sample chamber and a hub portion located proximal to the sample chamber. The needle carrier has a holding portion. The holding portion and the hub portion are collectively configured to form a detent mechanism configured to permit the biopsy needle to rotate within needle carrier to rotationally position the sample chamber while restraining rotation of the biopsy needle at a series of rotational detent positions. | 09-20-2012 |

20100317277 | AIR OUTLET - An air outlet has at least one air supply line and at least one baffle plate, wherein the opening cross section of the air supply line is arranged in a plane running parallel to the baffle plate, the baffle plate has a circumferential contour, and is spaced apart from the air supply line, and the opening cross section of one end of the air supply line is directed toward the baffle plate. Such air outlets are particularly suited for small-volume rest rooms, such as in a vehicle, which require a sufficiently high ventilation quality at the lowest possible draught. | 12-16-2010 |
