20100152610 | Hand Actuated Tetherless Biopsy Device with Pistol Grip - A hand actuated biopsy device comprises a vacuum generation mechanism and a tissue cutting mechanism manually actuated by a trigger of the hand actuated biopsy device. Hand manipulation or actuation of the trigger is used to power a vacuum pump to generate vacuum and to power the tissue cutting mechanism. The hand actuated biopsy device has a tissue piercing needle with a tissue receiving aperture. A tissue cutter translates and rotates within the needle and is powered by actuations of the trigger. When the needle is placed into tissue and the trigger is actuated to power the vacuum pump and the tissue cutter, tissue is drawn into the tissue receiving aperture and severed by the hand powered cutter. A tissue collection chamber can be attached to the hand actuated biopsy device to receive severed tissue samples within. | 06-17-2010 |
20100152611 | Hand Actuated Tetherless Biopsy Device with Scissors Grip - A biopsy device includes a body having a cannula, a cutter positioned at least partly within the cannula, a tissue collection chamber, and a vacuum source. In one example, the biopsy device includes a cutter loader for rotating the cutter into a loaded position (e.g., open position). A trigger is engaged with a portion of the cutter loader and may be activated to allow the cutter to rotate back to a closed position. During this rotation, the cutter severs a tissue sample, which may thereafter be drawn through the cutter lumen into the tissue collection chamber under the influence of a vacuum created by the vacuum source. The vacuum source includes a piston configured to be operated by squeezing a scissors grip. A user may apply a single stroke or successive strokes to the piston to produce the vacuum. | 06-17-2010 |
20100292607 | TETHERLESS BIOPSY DEVICE WITH SELF-REVERSING CUTTER DRIVE MECHANISM - A biopsy device comprises a body, a needle, and a cutter. A self-reversing cutter translation mechanism translates the cutter proximally and distally in response to rotation of the cutter in a single rotational direction. The cutter translation mechanism comprises a lead screw with discretely formed threads and a rotatable pawl. The cutter is translated proximally when the pawl is in a first rotational orientation; and distally when the pawl is in a second rotational orientation. Resilient members cause the pawl to be rotated between the first and second rotational orientations when the cutter reaches a distal position and a proximal position. A vacuum draws severed tissue samples through the interior of the cutter to deposit the samples in a holder. The translation mechanism engages a valve mechanism to provide simultaneous venting to part of the needle and reversal of the pawl orientation when the cutter reaches a distal position. | 11-18-2010 |
20100317990 | Biopsy Targeting Cube with Elastomeric Edges - A biopsy system comprises a control module, a localization assembly, a biopsy device, and a targeting cube. The biopsy device comprises a holster portion and a probe. The probe and/or other associated components are configured to selectively couple with a targeting cube that is configured to selectively couple with a grid plate having apertures for receiving the targeting cube.

The biopsy device comprises a holster portion and a probe. The probe and/or other associated components are configured to selectively couple with a targeting cube that is configured to selectively couple with a grid plate having apertures for receiving the targeting cube. The targeting cube comprises a body defined by faces. The targeting cube further comprises guide holes that originate and terminate at the faces and pass through the body of the targeting cube to provide a passageway through the targeting cube. The body of the targeting cube is at least partially comprised of elastomeric material to allow for compression of the body. The elastomeric material may thus provide a secure fit with a wide range of grid plates having openings of various shapes and sizes. | 12-16-2010 |
20100317992 | Biopsy Targeting Cube with Malleable Members - A biopsy system comprises a control module, a localization assembly, a biopsy device, and a targeting cube. The biopsy device comprises a probe and other components, which selectively couple with a targeting cube that is configured to selectively couple with a grid plate having apertures for receiving the targeting cube. The targeting cube comprises a body defined by faces, and guide holes that originate and terminate at the faces and pass through the body of the targeting cube to provide passageways through the targeting cube. The body of the targeting cube is at least partially comprised of elastomeric material to allow for adjustment of the orientation of the passageways. The body of the targeting cube is further comprised of malleable members that flank the passageways and allow for angulation of an instrument, such as by maintaining an adjusted orientation of a passageway into which the instrument is inserted. | 12-16-2010 |
20100317993 | Biopsy Targeting Cube with Angled Interface - A biopsy system comprises a control module, a localization assembly, a biopsy device, and a targeting cube. The biopsy device comprises a probe and other components, which selectively couple with a targeting cube that is configured to selectively couple with a grid plate having apertures for receiving the targeting cube. The targeting cube comprises a body defined by faces. The targeting cube further comprises guide holes that originate and terminate at the faces and pass through the body of the targeting cube to provide passageways through the targeting cube. The faces of the targeting cube comprise a tapered profile from a proximal end to a distal end. The tapered profile of the targeting cube may be created by the faces themselves or by protruding elements from the faces. The body of the targeting cube and/or the protruding elements may be at least partially comprised of an elastomeric material. | 12-16-2010 |
20100324445 | MRI Biopsy Cylindraceous Targeting Guide - A biopsy system comprises a biopsy device, a localization grid plate, and a targeting guide. The grid plate is configured to localize part of a patient (e.g., a breast), and defines a plurality of openings. The guide is insertable into a selected opening in the grid plate and comprises a cylindraceous body. The body defines passageways for inserting a probe and/or other associated components, and is rotatable to position the passageways to selectively define an insertion axis for the probe and/or other components. The targeting guide may thus guide the probe and/or other components as such components are inserted into the localized part of the patient; and may further support the probe and/or other components after insertion. The openings of a grid plate into which the cylindraceous body is inserted may be square, may be cylindraceous to complement the configuration of the guide, or may have some other configuration. | 12-23-2010 |
20130116717 | ULTRASONIC DEVICE FOR CUTTING AND COAGULATING - An ultrasonic assembly that is configured to permit selective cutting, coagulation, and fine dissection required in fine and delicate surgical procedures. The balanced blade provides a rounded distal end and concave edges to promote fine dissection and cutting in a variety of surgical procedures. The blade is curved for improved visibility at the blade tip and is designed to provide a multitude of tissue effects: coagulation, cutting, dissection, spot coagulation, tip penetration and tip scoring. The assembly features hand activation configured to provide an ergonomical grip and operation for the surgeon. The assembly further features user selectable blade rotation. A finger switch is placed in the range of the natural axial motion of the user's index finger, whether gripping the surgical instrument right-handed or left handed. | 05-09-2013 |
20140031717 | BIOPSY DEVICE - A biopsy device comprises a body and a needle extending distally from the body.

One of the apposed distal cannula portions may be removed. The remaining distal cannula portion may be formed into a blade of the tissue piercing tip. A cutter may be moved relative to the needle to sever samples from tissue protruding through a transverse aperture formed in the cannula. A gap may be provided between the exterior of the cutter and the interior of the cannula, permitting the cutter to be distally vented while a proximal vacuum is communicated to the cutter to transport severed tissue samples proximally through the cutter. | 01-30-2014 |
