The biopsy device includes a probe, a needle, a cutter, and a transport valve. The needle extends distally from the probe. The cutter is movable relative to the needle and defines a cutter lumen. The holster is configured to couple to the probe. The transport valve is in communication with the cutter lumen. The control module is in communication with the biopsy device and includes a sample management assembly configured to receive one or more tissue samples severed by the cutter. The transport tube extends between the sample management assembly and the biopsy device. The transport tube is in communication with the transport valve such that the transport tube is configured to receive the one or more tissue samples severed by the cutter.Type: ApplicationFiled: October 14, 2022Publication date: February 2, 2023Inventors: Bryan R. Keller, John Kevin Bruce, Peter Shadix, Rachel Yoon Choung, David Shuart, Jordan Rebellino, Andrew Paul Nock, Bryan Superville

Publication number: 20210121163Abstract: A biopsy device includes a body, a needle, a cutter, an analysis area, a valve, and a tissue sample holder. The cutter is movable relative to the needle and in communication with the needle for transporting tissue samples. The analysis area is disposed proximally of the cutter and in communication with the needle to receive a tissue sample cut by the cutter for analysis by a user. The valve is disposed proximally of the analysis area and configured to alternate between an open configuration and a closed configuration. The tissue sample holder is disposed proximally of the valve and fixedly attached to the body. The valve is configured to permit analysis of the sample disposed in the analysis area when the valve is in the closed configuration and to permit the tissue sample to be passed into the tissue sample holder when the valve is in the open configuration.Type: ApplicationFiled: January 4, 2021Publication date: April 29, 2021Inventors: Rachel Yoon Choung, Robert M.

Patent number: 10463348Abstract: A biopsy device holder includes a needle holder, a distal holder, and a proximal holder. The needle holder includes an elongated housing extending between an open proximal end and a distal end. The needle holder is adapted to releasably receive the biopsy device through the open proximal end. The elongated housing includes a coupler configured to couple the needle holder to the biopsy device. The distal holder includes an opening configured to pivotably receive the distal end of the needle holder. The proximal holder includes a longitudinal stop that engages with a portion of the needle holder to prevent the needle holder from proximal longitudinal movement. The longitudinal stop is configured to disengage the coupler of the needle holder from the biopsy device when the biopsy device is moved proximally in a longitudinal direction.Type: GrantFiled: August 30, 2018Date of Patent: November 5, 2019Assignee: Devicor Medical Products, Inc.Inventors: David Shuart, Andrew Paul Nock, Andrew Robinson, Rachel Yoon Choung, Mark Graham
