Abstract
The invention features a device for obtaining tissue samples from a site deep within the body having a proximal portion constructed to follow a long torturous path to the site and a distal portion constructed with a jaw arrangement that can be opened and closed to sever a sample, including tissue specimens, polyps and the like, from the surface. The device is constructed for severing and storing at least three successive samples. The device includes a sample storing and retaining element in the space encompassed by the jaws. The element is fixed to maintain an orientation extending generally distally along a selected length to a distal end and has a profile along the length for engaging multiple samples arranged axially in the order in which they were severed from the surface with sufficient frictional force to substantially retain the samples from moving distally from the space encompassed by the jaws when the jaws are opened to sever a successive sample from the surface.
