Method of manufacturing a needle assembly for use with a biopsy device

A process of manufacturing a biopsy needle assembly comprising:

• forming an aperture for receiving tissue to be sampled in an exterior surface of an elongated tube for receiving a cutter and having a proximal portion and a distal portion;
• forming a hole in said exterior surface of said elongated tube;
• and
• placing said elongated tube in a mold and injecting said mold with a material, wherein said mold is configured such that said material forms a lumen for receiving vacuum on said exterior surface of said elongated tube, wherein said hole in said exterior surface of said elongated tube provides communication between an interior of said elongated tube and an interior of said lumen.

A process of manufacturing a biopsy needle assembly comprising:

• placing a cutter tube comprising a port adapted to receive a tissue sample, and further comprising a cutter lumen adapted to receive a cutter, in a mold;
• injecting a material in a liquid state into said mold;
• cooling said material in order to convert it to a solid state;
• wherein said mold is configured to cause said material to form a lumen for receiving vacuum on an exterior surface of said cutter tube;
• wherein further said lumen for receiving vacuum is in communication with said cutter lumen.
