Abstract
A single use biopsy device (100) is disclosed. The device (100) includes a receptacle (102) having a port (104) for allowing tissue from a biopsy site to protrude into the receptacle (102) and a cutter (106) that is supported in the receptacle (102) and arranged so that when tissue from a biopsy site protrudes into the receptacle (102) through the port (104) the cutter (106) is movable to sever the tissue so as to obtain a biopsy sample. A stop (108) arrests the cutter (106) after the cutter (106) has severed the tissue. The arresting of the cutter by the stop (108) prevents reuse of the device (100). A method of obtaining a biopsy sample from a biopsy site using the biopsy device (100) is also disclosed.

2 more elements
A single use biopsy device, including:
- an elongate receptacle having a distal end, a proximal end, and a port located proximal to the distal end for allowing tissue from a biopsy site to protrude into an interior region of the receptacle;
- a planar cutter supported inside the receptacle so as to be movable along the longitudinal axis of the receptacle by a cutter driver;

2 more elements
A single use aspiration biopsy device, including:
- an elongate receptacle having a distal end and a proximal end, the receptacle including a port located proximal to the distal end for allowing tissue from a biopsy site to protrude into an interior region of the receptacle and an opening located at the proximal end for receiving a cutter driver;
- a cutter supported in the receptacle, the cutter being movable by a cutter driver to sever tissue protruding into the interior region to obtain a biopsy sample for containment in the interior region;

- and
- a seal located between the opening and the internal region, the seal having an inside perimeter for sealably engaging with a cutter driver;
- wherein at least a portion of the cutter is located radially inwardly relative to the inside perimeter of the seal for access by a cutter driver having an outside perimeter of substantially the same size as the inside perimeter of the seal, and wherein the cutter and the stop are arranged to sever the tissue when the cutter bears against, or embeds into, the stop.
3 more elements
An aspiration biopsy system, the system including:
- a single use biopsy device, the device including a receptacle having a port for allowing tissue from the biopsy site to protrude into the receptacle, an interior region for containing a biopsy sample obtained by the device, a cutter supported in the receptacle and arranged so that when tissue from a biopsy site protrudes into the receptacle through the port the cutter is movable to sever the tissue so as to obtain a biopsy sample, and a stop for arresting the cutter after the cutter has severed the tissue so that the arresting of the cutter prevents reuse of the device, wherein the cutter and the stop are arranged to sever the tissue when the cutter bears against, or embeds into, the stop;
- a seal positioned in the receptacle and arranged to receive a section of the cutter driver so that an outside perimeter of the cutter driver forms a sealed engagement with an inside perimeter of the seal;
- a suction line connecting the interior region of the receptacle to a suction source operable to reduce pressure in the receptacle so as to thereby draw tissue into the interior region, the suction line including a cutter driver that is operable to move the cutter;
