Abstract

A biopsy apparatus and method for taking internal tissue samples having an outer sleeve (10) with a cutting edge (15), a hollow needle (20) with a plurality of tissue ports (25) and a vacuum source that is in fluid communication with a vacuum mechanism that contains a plurality of vacuum sections (40) to direct and control the application of the vacuum. The hollow needle (20) contains a plurality of tissue ports (25) positioned for severing at least one tissue sample while a vacuum is applied through at least one vacuum section (40). The method for the biopsy apparatus includes positioning the apparatus at least partially within a tissue portion to be sampled, withdrawing the outer member (10), moving adjustable vacuum sections as required to open at least one tissue port (25), applying the vacuum, and moving the outer member (10) to simultaneously sever at least one tissue sample. The biopsy apparatus is capable of severing single tissue samples sequentially and multiple tissue samples simultaneously.
