主权项

1. A biopsy instrument for the enrichment of sample material, comprising:
i. a non-magnetic guide element comprising a spring-elastic distal most portion of the guide element and a proximal portion, ii. a magnetic element having a first end and a second end that is fitted between the distal portion and the proximal portion of the guide element, and iii. a non-magnetic stabilizing element connected to the proximal portion of the guide element, wherein the first end of the magnetic element directly abuts the spring-elastic distal portion of the guide element and the second end of the magnetic element directly abuts the stabilizing element, wherein the biopsy instrument is configured for the enrichment of the sample material and for insertion into a body of a subject, and wherein the stabilizing element is configured to stabilize the magnetic element during a biopsy and to avoid dislocation of the magnetic element and the stabilizing element being a. adhesively bonded and/or welded to the proximal portion of the guide element, or b. adapted to be slid over the proximal portion of the guide element.
