20110144533 | INTRODUCER CANNULA HAVING A TISSUE ANCHOR FOR USE WITH A MEDICAL INSTRUMENT - An introducer cannula configured for receiving a medical instrument includes a cannula tube having a side wall surrounding a central lumen, a proximal end, and a distal end. An elongate tissue anchor is positioned in the central lumen of the cannula tube. The elongate tissue anchor has a mounting end and an anchoring free end. The elongate tissue anchor is movable in the central lumen such that the anchoring free end is movable between a retracted position and a deployed position. An actuator is coupled to the proximal end of the cannula tube. The actuator is coupled to the mounting end of the elongate tissue anchor. The actuator is operatively configured to selectively position the anchoring free end of the elongate tissue anchor in one of the retracted position and the deployed position. | 06-16-2011 |
20110152716 | BIOPSY PROBE MECHANISM HAVING MULTIPLE ECHOGENIC FEATURES - A biopsy probe mechanism includes an elongate sample receiving member having a longitudinal axis and having a sample receiving notch. An elongate sample receiving member and a cutting cannula are movable relative to one another along a longitudinal axis between a first relative position and a second relative position. A first echogenic feature is established on the elongate sample receiving member and a second echogenic feature is established on the cutting cannula. The first echogenic feature is in longitudinal alignment with the second echogenic feature when the elongate sample receiving member and the cutting cannula are in the first relative position. The first echogenic feature is out of longitudinal alignment with the second echogenic feature when the elongate sample receiving member and the cutting cannula are in the second relative position. | 06-23-2011 |
20120130275 | BIOPSY APPARATUS HAVING INTEGRATED THUMBWHEEL MECHANISM FOR MANUAL ROTATION OF BIOPSY CANNULA - A biopsy apparatus includes a driver assembly and biopsy probe mechanism drivably coupled to the driver assembly. The biopsy probe mechanism includes a biopsy cannula having a cylindrical side wall that defines a lumen and has a side port located near a distal end that extends through the side wall to the lumen. A thumbwheel mechanism includes a thumbwheel mounted to the driver assembly to rotate about a first rotational axis, the first rotational axis being substantially perpendicular to the longitudinal axis. A first gear is mounted to the thumbwheel for coaxial rotation with the thumbwheel about the first rotational axis. A second gear is mounted to the biopsy cannula for coaxial rotation with the biopsy cannula about the longitudinal axis, the second gear being located to be drivably engaged by the first gear. The housing is grasped and the thumbwheel rotated with a single hand. | 05-24-2012 |
20120283596 | Biopsy Device - A method for using a biopsy device is disclosed. The biopsy device includes a chamber having a body having a distal end and a proximal end, wherein the proximal end includes an inlet. The biopsy device further includes a vacuum generator for generating negative and positive pressure and at least one first recessed area and at least one second recessed area. The first recessed area extends along an inner wall of the body, proximate the proximal end of the body of the chamber. The first recessed area is configured to release positive pressure within the chamber. The second recessed area extends along the inner wall of the body, proximate the distal end of the body of the chamber. The second recessed area is configured to release negative pressure within the chamber. | 11-08-2012 |
20130289442 | BIOPSY PROBE MECHANISM HAVING MULTIPLE ECHOGENIC FEATURES - A biopsy probe mechanism includes an elongate sample receiving member having a longitudinal axis and having a sample receiving notch. An elongate sample receiving member and a cutting cannula are movable relative to one another along a longitudinal axis between a first relative position and a second relative position. A first echogenic feature is established on the elongate sample receiving member and a second echogenic feature is established on the cutting cannula. The first echogenic feature is in longitudinal alignment with the second echogenic feature when the elongate sample receiving member and the cutting cannula are in the first relative position. The first echogenic feature is out of longitudinal alignment with the second echogenic feature when the elongate sample receiving member and the cutting cannula are in the second relative position. | 10-31-2013 |
20140066805 | BIOPSY DEVICE - A biopsy device is disclosed. The biopsy device includes a chamber having a body having a distal end and a proximal end, wherein the proximal end includes an inlet. The biopsy device further includes a vacuum generator for generating negative and positive pressure and at least one first recessed area and at least one second recessed area. The first recessed area extends along an inner wall of the body, proximate the proximal end of the body of the chamber. The first recessed area is configured to release pressure within the chamber. The second recessed area extends along the inner wall of the body, proximate the distal end of the body of the chamber. The second recessed area is configured to release pressure within the chamber. | 03-06-2014 |
20150018712 | BIOPSY DEVICE - A biopsy device includes a pressure chamber having a body having a distal end and a proximal end, wherein the proximal end includes an inlet. At least one first recessed area extends along an inner wall of the body, proximate the proximal end of the body of the pressure chamber. The first recessed area is configured to release pressure within the pressure chamber. At least one second recessed area extends along the inner wall of the body, proximate the distal end of the body of the pressure chamber. The second recessed area is configured to release pressure within the pressure chamber. A cannula is coupled to the pressure chamber for taking a tissue sample from a patient. The cannula defines a tissue chamber. A fluid receptacle is interposed between the tissue chamber and the pressure chamber. The fluid receptacle has an absorbent material to absorb a fluid. | 01-15-2015 |
