Patent number: 10251631Abstract: A biopsy device includes coaxially disposed inner and outer needles in which the outer needle tip is configured for obtaining a tissue sample. The inner surface of the outer needle includes a tissue retention feature which may include a countersink and/or a feature formed in the inner surface. The device may be introduced to a biopsy site through an introducer in which the introducer is vented and/or a certain ratio of introducer inner diameter and biopsy device outer diameter is maintained.Type: GrantFiled: May 10, 2016Date of Patent: April 9, 2019Assignee: PAVE, LLCInventors: Deborah R. Beck, Dan C. Ireland

Patent number: 9579087Abstract: A flexible biopsy needle assembly includes a flexible coring stylet that is slidably disposed within a flexible outer cannula. The stylet includes an elongated body, a tip, a sampling notch adjacent to the tip, and at least one ferrule along the length of the body. The cannula includes an elongated tubular body defining a lumen sized for sliding passage of the stylet, a cutting edge at the opening of the lumen, and an array of slits along the length of its body. The slits are sized to allow the diameter of the ferrule(s) to extend partially therein. The slits and ferrule(s) interact to limit or control the flexibility of the cannula at the location of the slits.Type: GrantFiled: November 15, 2011Date of Patent: February 28, 2017Assignee: Promex Technologies, LLCInventor: Dan C.

Patent number: 9463002Abstract: A biopsy device includes coaxially disposed inner and outer needles in which the outer needle tip is configured for obtaining a tissue sample. The inner surface of the outer needle includes a tissue retention feature which may include a countersink and/or a feature formed in the inner surface. The device may be introduced to a biopsy site through an introducer in which the introducer is vented and/or a certain ratio of introducer inner diameter and biopsy device outer diameter is maintained. The full core devices also permit a tighter tolerance between the I.D. and O.D. of the outer cannula and stylet, respectively, which further permits the use of a smaller gage introducer. Full devices also include a sample trap assembly operable to enlarge the sample cavity after the full core sample has been obtained.Type: GrantFiled: March 28, 2014Date of Patent: October 11, 2016Assignee: JJ Dogs LLCInventors: Douglas Perianu Knoll, Deborah Rae Beck, Dan C.

Patent number: 8313501Abstract: A surgical cutting instrument for cutting tissue includes an outer cannula with a cutting opening and a cutting member within the cannula. The cutting member is connected to a source of reciprocation, and as the cutting member reciprocates the cutting member head is guided by a sloped member within the cannula to essentially a zero clearance position relative to a cutting edge of the cutting opening of the cannula. The instrument cleanly severs tissue extending through the cutting opening into the outer cannula.Type: GrantFiled: September 12, 2008Date of Patent: November 20, 2012Assignee: Nico CorporationInventors: Sean Miller, Dan C.

Patent number: 7658718Abstract: A biopsy needle assembly for use in a biopsy gun includes coaxially slidably engaged outer needle and inner needles. The inner needle defines a cavity adjacent its distal end for receiving a tissue sample. A first hub is attached to the proximal end of the inner needle, and a second hub is attached to the proximal end of the outer needle. An elongated pin having a first end and a second end is fixedly attached to the first hub at the first end of the pin. The second end is in sliding contact with the second hub so that the second hub and the pin are slidable relative to each other. A stop engagement is provided between the second end of the pin and the second hub and is configured to prevent disengagement of the outer and inner needles and to maintain a specific physical relationship between the hubs.Type: GrantFiled: December 18, 2007Date of Patent: February 9, 2010Assignee: Promex Technologies, LLCInventors: Michael E.

Patent number: RE42049Abstract: An introducer guide 15 for introducing medical items into an internal tissue of a patient is provided. The guide 15 includes a cannula 20 defining a lumen sized to receive the item and a lateral opening 24. A ramp is disposed within the lumen adjacent and inclined toward the lateral opening 24. A hub 40? is attached to the second end 22 of the cannula 20. The hub 40? includes a gripping portion 41? configured to be held when inserting and positioning the introducer 15. The gripping portion 41? has a length lgp sufficient for gripping and a tactile indicator 44 disposed along substantially the entire length lgp of the gripping portion 41 on the hub 40?. The indicator 44 has a fixed angular relationship with the lateral opening 24. The invention also includes methods for obtaining a biopsy sample and methods for treating lesions.Type: GrantFiled: May 8, 2003Date of Patent: January 18, 2011Assignee: Promex Technologies, LLCInventors: David L.
