Abstract
A multiple biopsy device has a number of chambers into which tissue samples are received. A cutting mechanism, such as a blade, moves relative to the chambers to cut a tissue sample that is within a chamber. In one embodiment of the invention, the multiple biopsy device is removably secured to the distal end of an endoscope/bronchoscope.
Claims12
A device for obtaining multiple biopsy samples from a patient, comprising:
- a cap that is secured to the distal end of an endoscope, the cap having a number of biopsy chambers formed therein, each biopsy chamber having an opening through which tissue can enter the biopsy chamber;
- a cutter for cutting tissue that has entered the biopsy chamber;
- means for creating relative movement between the cutter and a biopsy chamber in order to cut tissue that has entered the biopsy chamber.
A device for obtaining multiple biopsy samples from a patient, comprising:
- an endoscope having a proximal end and a distal end;
- a cap removably secured to the distal end of the endoscope, the cap having:
- a plurality of biopsy chambers each of which has an opening in which a tissue sample can be received;
- a cutter for cutting tissue that enters a biopsy chamber;
- a seal for closing a biopsy chamber once a tissue sample is cut and received in the biopsy chamber;
- and
- an advancing mechanism for sequentially positioning the cutter over the openings of the plurality of biopsy chambers.
