Patent number: 7981049Abstract: A biopsy system includes a biopsy device, a vacuum canister, a vacuum control module, and a plurality of tubes. A first tube is configured to provide an axial vacuum to the biopsy device, while a second tube is configured to provide a lateral vacuum. A third tube is configured to communicate atmospheric air to the second tube. A fourth tube is configured to communicate saline to the second tube. The vacuum canister is configured to collect fluids drawn through the first tube and the second tube. The canister has a lid with trenches formed in it for retaining the first, second, third, and fourth tubes. The lid also has engagement regions for selectively pinching each of the tubes against to prevent fluid communication through selected tubes. The canister can be removably inserted into the vacuum control module, which includes components for selectively pinching the tubes against the engagement regions.Type: GrantFiled: November 20, 2007Date of Patent: July 19, 2011Assignee: Devicor Medical Products, Inc.Inventors: Paul G.

Publication number: 20110144532Abstract: A biopsy device and method are provided for obtaining a tissue sample, such as a breast tissue biopsy sample. The biopsy device includes a disposable probe assembly with an outer cannula having a distal piercing tip, a cutter lumen, and a cutter tube that rotates and translates past a side aperture in the outer cannula to sever a tissue sample. The biopsy device also includes a reusable hand piece with an integral motor and power source to make a convenient, untethered control for use with ultrasonic imaging. External vacuum holes along the outer cannula (probe) that communicate with a vacuum and cutter lumen withdraw bodily fluids while a hemostatic disk-shaped ring pad around the probe applies compression to an external hole in the skin and absorbs fluids.Type: ApplicationFiled: February 11, 2011Publication date: June 16, 2011Applicant: DEVICOR MEDICAL PRODUCTS, INC.Inventors: Gavin M.

Patent number: 7938786Abstract: A biopsy system has a cutter defining a cutter lumen along an axis. One conduit in the system is configured to provide fluid communication along the cutter lumen axis; while another conduit in the system is configured to provide fluid communication lateral to the cutter lumen axis. The system may be operated in a variety of modes, including a sample cycle, a clear probe cycle, a cutter positioning cycle, an aspirate cycle, and a maintenance vacuum pulse cycle. The operational modes are selectable by a user. Depending on the mode selected by the user, the communication of vacuum, saline, or atmospheric air through the conduits, or the sealing of the conduits, will vary as a function of the axial position of the cutter.Type: GrantFiled: November 20, 2007Date of Patent: May 10, 2011Assignee: Devicor Medical Products, Inc.Inventors: Paul G.
