  • Patent number: 11457901
    Abstract: A tissue collection device (1) for collection of one or more exposed tissue samples (2) from a biopsy needle or biopsy device, which tissue collection device comprises one or more pieces of a carrier medium (6) 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 (2) adheres to the carrier medium (6) and is removed from the biopsy needle (3) or biopsy device (4) with the carrier medium (6), when the carrier medium (6) is removed from the biopsy needle or biopsy device again. Furthermore, a biopsy device comprising such a tissue collection device is disclosed.

  • Publication number: 20210153850
    Abstract: A tissue collection device including a biopsy needle support arrangement to support a biopsy needle so that a tissue compartment in the biopsy needle may be located at a collection position. The tissue collection device includes a carrier medium adapted to adhere to and carry a tissue sample deposited thereon and adapted to be arranged at a deposition position permanently spaced from the collection position. The tissue collection device includes a swiping element adapted to swipe sideward relative to the longitudinal direction through the tissue compartment located at the collection position and in the direction of the deposition position in order to thereby move a tissue sample from the tissue compartment to the carrier medium and to thereby press the tissue sample onto the carrier medium so that the tissue sample is deposited on the carrier medium.

  • Patent number: 10441253
    Abstract: 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.

  • Publication number: 20160262735
    Abstract: The present invention relates in one aspect to an endoscopic biopsy device (1, 2) for collecting multiple samples (10x). The endoscopic biopsy device comprises a tubular body (10) having in an axial direction a distal end and a proximal end, jaws (20, 21, 22) that are hinged to the distal end of the body, wherein the jaws are operable between an OPEN position and a CLOSED position to secure a tissue sample (100), and wherein the jaws in the CLOSED position define a sampling chamber (23); a collecting chamber (13) for receiving multiple samples, the collecting chamber being located within the body in an axial direction proximally adjacent to the sampling chamber; and an axially extending collecting member (30) for transfixing secured samples, the collecting member being axially displaceable between a retracted position in the collecting chamber and a deployed position where the collecting member penetrates into the sampling chamber.

  • Patent number: 8100676
    Abstract: The invention relates to a rotor for a positive displacement rotary pump. The rotor comprises a hub with an aperture and a center axis through aperture and at least 2 lobes radially extending from hub and in a direction essentially perpendicular to the axis of hub. The rotor comprises a core of a first polymer material and a cover of a second polymer material, which second polymer material has a hardness which is lower than the first polymer material. The first and the second polymer materials are connected to each other. The hub or the major part of the hub is preferably provided by the core, whereas at least a part of the lobes is provided by the cover. The invention also relates to a method of providing the rotor and a pump comprising the rotor.
