Biopsy apparatus having integrated fluid management
First Claim
1. A biopsy apparatus, comprising:
- (a) a driver assembly configured to be grasped by a user, including;
an electromechanical power source;
a vacuum source; and
a first vacuum path permanently associated with said vacuum source, said first vacuum path having a proximal end and a distal end, said proximal end being fixedly coupled to said vacuum source in fluid communication therewith, said first vacuum path having a first one-way valve configured and arranged to permit a negative pressure fluid flow toward said vacuum source and to prevent a positive pressure fluid flow away from said vacuum source toward said distal end;
(b) a disposable biopsy probe assembly configured for releasable attachment to said driver assembly, said disposable biopsy probe assembly including;
a transmission device configured to drive engagement with said electromechanical power source;
a biopsy probe drivably coupled to said transmission device, said biopsy probe having a sample basket configured to receive a biopsy tissue sample; and
a second vacuum path having a first end and a second end, said first end being configured for removable attachment to said distal end of said first vacuum path and said second end being coupled in fluid communication with said sample basket, said second vacuum path having a second one-way valve configured and arranged to permit the negative pressure fluid flow from said sample basket and to redundantly prevent the positive pressure fluid flow from said first end of said second vacuum path toward said sample basket; and
(c) a vacuum monitoring mechanism coupled to said vacuum source and configured to shut off said vacuum source when a vacuum level in at least one of said first vacuum path and said second vacuum path reaches a predetermined level.

Abstract
A biopsy apparatus includes a driver assembly to be grasped by a user and a disposable biopsy probe assembly for releasable attachment to the driver assembly. The driver assembly includes a first vacuum path having a first one-way valve configured and arranged to permit a negative pressure fluid flow toward a vacuum source and to prevent a positive pressure fluid flow away from the vacuum source. The disposable biopsy probe assembly includes a second vacuum path having a second one-way valve configured and arranged to permit the negative pressure fluid flow from a sample basket and to redundantly prevent the positive pressure fluid flow toward the sample basket. A vacuum monitoring mechanism is coupled to the vacuum source and configured to shut off the vacuum source when a vacuum level in at least one of the first vacuum path and the second vacuum path reaches a predetermined level.
