Patent number: 9709467Abstract: The invention relates to an apparatus for treating histological samples, in particular for detaching and/or isolating a histological sample that, in particular after an infiltration operation, is adhering to another sample and/or to the inside of a cassette (1), having a sample receiving chamber (2) which is embodied and intended to be filled at least partly with a liquid (3), in particular with liquid paraffin. The apparatus according to the present invention is characterized in that a displacement means (5) is provided that is introducible into the liquid (3), in particular under open- and/or closed-loop control, in order to elevate the fill level height (6) of the liquid (3), and/or that a displacement means (5) is provided whose volume is increasable, in particular under open- and/or closed-loop control, in order to elevate the fill level height.Type: GrantFiled: September 4, 2014Date of Patent: July 18, 2017Assignee: Leica Biosystems Nussloch GmbhInventors: Arne Burisch, Christian Löchte, Annika Raatz, Hermann Ulbrich, Karl-Heinrich Westerhoff

Patent number: 9377382Abstract: The invention provides a method for detaching and/or isolating a histological sample that is adhering to another sample and/or to the inside of a cassette, for example as a result of solidification of an embedding medium within a cassette. The sample is immobilized in a sample receiving chamber above a first fill level of a liquid that is suitable for counteracting the adhesion; and that the fill level of the liquid is then elevated at least until said level reaches the sample. An apparatus according to the present invention that can be used for carrying out the method comprises a sample receiving chamber and an adjusting chamber, the adjusting chamber being connected to the sample receiving chamber in such a way that a change in the fill level height of the liquid in the sample receiving chamber is producible by changing the pressure existing in the adjusting chamber.Type: GrantFiled: May 13, 2014Date of Patent: June 28, 2016Assignee: Leica Biosystems Nussloch GmbHInventors: Arne Burisch, Christian Löchte, Annika Raatz, Hermann Ulbrich, Karl-Heinrich Westerhoff

Patent number: 9121796Abstract: The invention relates to a method for execution upon processing of at least one histological sample that is arranged, in particular after an infiltration process, in a closed cassette (2). The method is characterized in that prior to opening of the cassette (2), the sample is detached from the cover of the cassette (2) and/or isolated.Type: GrantFiled: March 13, 2014Date of Patent: September 1, 2015Assignee: LEICA BIOSYSTEMS NUSSLOCH GMBHInventors: Arne Burisch, Christian Löchte, Annika Raatz, Hermann Ulbrich, Karl-Heinrich Westerhoff
