Abstract
Official abstract text for this publication.
A biopsy device includes a handle unit, a hollow needle comprised in a disposable unit, which is releasably attached to the handle unit, and a sample-receiving device, which is movable in the hollow needle between two positions. Tissue is severed when the sample-receiving device is in a first one of the positions, and the severed tissue sample is ejected from the sample-receiving device in a second one of the two positions. A control system is provided for controlling movement of the sample-receiving device and for arresting the sample-receiving device in the second position. The distance between the two positions and/or a length of the hollow needle may be detectable in a calibration cycle, which is automatically initiated upon attachment of the disposable unit to the handle unit. The disposable unit may include electronic memory device for communicating with the control system.
First claim
Opening claim text (preview).
What is claimed is: 1. A biopsy device for harvesting at least one tissue sample from a body of a living being, the device comprising: a handle unit; a longitudinally extending hollow needle with a distal end portion adapted to be introduced into the body, the distal end portion of the hollow needle having a cutting edge configured to sever the at least one tissue sample; a sample-receiving device with a closed distal end and a side accessible cavity proximal to the closed dis…
