First Claim
Patent Images
1. 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 isolated 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 single, isolated biopsy chamber of the number of biopsy chambers in order to cut tissue that has entered the single, isolated biopsy chamber.

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.

7. 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 isolated biopsy chambers each of which has an opening in which a tissue sample can be received;
a cutter for cutting tissue that enters an isolated biopsy chamber;
a seal for closing a biopsy chamber once a tissue sample is cut and received in the isolated biopsy chamber; and
an advancing mechanism for sequentially positioning the cutter over a single isolated biopsy chamber of the plurality of isolated biopsy chambers. - View Dependent Claims (8, 9)

10. A method of obtaining multiple biopsy samples from a patient, comprising:
-
inserting an endoscope into a patient having a cap secured to the distal end of the endoscope, the cap including two or more isolated chambers;
applying vacuum to a chamber to draw tissue into a single isolated chamber;
moving the isolated chamber relative to a tissue cutter to cut tissue from the patient;
sealing the isolated chamber before obtaining a tissue sample in another isolated chamber prior to removing the endoscope from the patient. - View Dependent Claims (11, 12)
