摘要:
A flocked swab for collection and transfer of samples of biological material, in which the swab comprises a support body having an elongate conformation and having a first end portion and a gripping portion, and a flocked layer defined by a plurality of fibres attached and arranged on the first portion of the support body by flocking, so as to realize a flocked collecting portion aimed at absorbing a quantity of a sample of biological material, the first portion of the support body being provided with a first weakening portion aimed at enabling and facilitating a selective breakage of the swab at the first portion and a separation of a first part of the flocked collecting portion from a second part of the flocked collecting portion and from the gripping portion.

A biopsy device comprises a coring and transport assembly and a distal beak assembly. The distal beak assembly may be coupled to or near a distal end of the coring and transport assembly and may comprise at least one movable cutting element. The distal beak assembly may be configured to rotate about an axis, and assume at least a first open configuration operative to enable the at least one cutting element to core through tissue and a second closed configuration operative to enable the at least one cutting element to move through the tissue and to sever a cored specimen from the tissue.

A tissue penetrating trocar or probe end, comprising: a. a proximal base configured to be secured to a probe shaft; b. a sharp distal point distal to the proximal base; c. a first concave surface; b. a second concave surface which intersects the first concave surface forming therewith a curved cutting edge that leads to the sharp distal point; and c. a third concave surface which intersects the first concave surface forming therewith a second curved cutting edge leading to the sharp distal point and which intersects the seccond concave surface forming therewith a third curved cutting edge that leads to the sharp distal point.

A biopsy device includes a first jaw and a second jaw pivotally connected to the first jaw through a pivot. The second jaw has a lever arm extending rearward from the pivot when the second jaw is closed. A wire having an end is connected to the lever arm of the second jaw. A suction tube is disposed between the first and second jaw.
