Abstract
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 has a distal end constructed to sever and 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 The instrument is constructed to take multiple biopsy samples without being withdrawn from the body. The instrument includes a tissue sample retractor. The retractor is axially movable between an extended tissue-engaging position and a retracted position. There is an open passage into which the retractor moves when moving from the extended to the retracted position. The retractor has a distal end portion constructed to engage tissue and apply axial transporting force thereto while moving from the extended to the retracted position. The retractor is constructed to be advanced and retracted repeatedly to accumulate a series of samples in the instrument.
