Patent number: 11224412Abstract: A biopsy device includes a needle extending distally from a body. The needle includes a transverse aperture, a first lumen, and a second lumen. A cutter is movable within the first lumen to sever tissue protruding through the transverse aperture. A valve assembly is operable to change the pneumatic state of the second lumen. The valve assembly includes a valve body and a translating member slidably disposed in a bore of the valve body. The valve body includes a first port and a second port. The first port is in fluid communication with the second lumen of the needle. The second port is in fluid communication with atmospheric air. The translating member selectively couples the first port with the second port based on the longitudinal position of the translating member within the bore. The translating member translates relative to the valve body based on the position of the cutter.Type: GrantFiled: January 9, 2018Date of Patent: January 18, 2022Assignee: Devicor Medical Products, Inc.Inventors: John A. Hibner, Andrew T. Beckman, Lee Reichel, Chris W. Cicenas, Luke C. Stonis

Patent number: 8068895Abstract: An instrument for deploying a marker at a site within a patient may include an elongate cannula, an elongate pusher, and a marker disposed within the cannula. The cannula may have a tip at its distal end and a transverse opening. The pusher may be disposed within the cannula, and may be moved longitudinally within the cannula. The pusher may have a ramped distal end. The marker may be configured to exit the transverse opening upon urging by the ramped distal end of the pusher. In some versions, the tip of the cannula has a flat proximal face, and the marker has a recessed region that is configured to buckle in response to longitudinal compression, such that the marker will pop out of the cannula upon buckling. In other versions, the cannula has an external sheath, an open and curved distal end, or a leaf spring.Type: GrantFiled: February 25, 2008Date of Patent: November 29, 2011Assignee: Devicor Medical Products, Inc.Inventors: Trevor W.

Patent number: 7895725Abstract: An improved process for manufacturing a biopsy needle assembly is provided. The process may comprise the steps of forming an aperture for receiving tissue to be sampled in an exterior surface of an elongated tube for receiving a cutter, wherein the elongated tube comprises a proximal portion and a distal portion; forming a hole in the exterior surface of the elongated tube; and applying a coating of material over the elongated tube to form a lumen for receiving vacuum on the exterior surface of the elongated tube, wherein the hole in the exterior surface of the elongated tube provides communication between an interior of the elongated tube and an interior of the lumen. In one version, the elongated tube may be placed in a mold configured to form the vacuum lumen when material is injected into the mold. A proximal hub may advantageously be formed by overmolding.Type: GrantFiled: May 8, 2009Date of Patent: March 1, 2011Assignee: Devicor Medical Products, Inc.Inventors: Andrew T.

Patent number: 7867173Abstract: 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. The reusable hand piece incorporates a probe oscillation mode to assist when inserting the distal piercing tip into tissue. A straw stacking assembly is automatically positioned by the reusable hand piece to retract multiple samples with a single probe insertion as well as giving a visual indication to the surgeon of the number of samples that have been taken.Type: GrantFiled: August 5, 2005Date of Patent: January 11, 2011Assignee: Devicor Medical Products, Inc.Inventors: John A.

Patent number: 7806834Abstract: A medical device for severing and removing small amounts of internal tissue for biopsy sampling or other purposes is disclosed. Versions of the device may include a hollow probe having a piecing tip, a tissue receiving aperture and a vacuum lumen; a cutter within the probe having a cutting edge that moves past the tissue receiving aperture, and a cutter driver mechanism. A cutter for use with versions disclosed herein may include an angled cutting tip and a cutting edge having a concave grind. Versions of the device also may include an aspirator fluidly connected to the vacuum lumen, coordinated operation of the aspirator and the cutter driver mechanism, and a fluid management system. Versions described may be used for removing multiple samples of tissue during a single insertion of the probe proximate to a target tissue mass.Type: GrantFiled: March 7, 2006Date of Patent: October 5, 2010Assignee: Devicor Medical Products, Inc.Inventors: Andrew T.
