Multi-motion side cutting biopsy sampling device

摘要

An instrument for obtaining tissue samples from a site deep within the body. The instrument has an elongated proximal portion that is constructed to follow a long, torturous path to the site and a distal end constructed to remove a tissue sample from the body, including tissue specimens, polyps or the like. The instrument is constructed to take multiple biopsy samples without being withdrawn from the body by including a storage space along the axis of the device suitable for storage of multiple, successively taken samples. The instrument includes a side-facing sampling element constructed such that it can be actuated in a first, rotational motion about the device axis to separate a tissue sample from the body and a second, axial motion for disposing the sample axially to facilitate positioning the sample in the storage space.
