International Classification:

A61B 6/02

US Classification:

600407, 600411, 600415, 600417, 600420, 600421, 600422, 600423, 600424, 600425, 600426, 600427, 600428, 600429, 600458, 600461, 128915, 128916, 378 37, 606130

Abstract:

A localization mechanism, or fixture, is used in conjunction with a breast coil for breast compression and for guiding a core biopsy instrument during prone stereotactic biopsy procedures in both open and closed Magnetic Resonance Imaging (MRI) machines. The localization fixture includes a fiducial marker and three-dimensional Cartesian positionable guide for supporting and orienting an MRI-compatible biopsy instrument with detachable probe/thumb wheel probe to the biopsy site of suspicious tissues or lesions.

Assignee:

Ethicon Endo-Surgery

International Classification:

A61B005/05

US Classification:

600/411000

Abstract:

A Magnetic Resonance Imaging (MRI) compatible core biopsy instrument includes a detachable probe assembly to enhance the accuracy of placement at a biopsy site and avoid repeated insertions, even when used in a closed MRI magnet bore. In particular, the detachable probe assembly is configured for attachment to a localization fixture for accurate stereotopic placement to the desired biopsy site. While disengaged, dual lumens (vacuum and cutter) of the probe assembly allow applying vacuum to, draining fluid from, and insertion of fluids to the biopsy site. The biopsy instrument handle readily engages to the probe assembly for taking samples. Features are included for visual indications of the position of the cutter, prevention of disengagement when the cutter is advanced into the probe assembly, and a tolerance take-out feature that minimizes the deadzone gap at a distal end of the probe assembly, allowing samples to be taken close to sensitive tissues.

International Classification:

A61B 10/02

US Classification:

600566, 600567

Abstract:

A biopsy device comprises a probe assembly and an obturator. The probe assembly comprises a cannula having a closed distal end configured to penetrate tissue, an open proximal end, a first lumen in fluid communication with the open proximal end, and a side aperture located proximal to the closed distal end. The side aperture is in fluid communication with the first lumen. The obturator is removably insertable in the first lumen through the open proximal end. The obturator is configured to substantially block the side aperture when the obturator is inserted in the first lumen. The probe assembly may be inserted in a patient's tissue (e.g., breast) with the obturator disposed in the cannula to block the side aperture. The obturator may then be removed, and a cutter may be advanced through the cannula to sever tissue protruding through the side aperture.

Appl. No.:

5/795083

Inventors:

David E. Beck - Middletown OH

Assignee:

Armco Steel Corporation - Middletown OH

International Classification:

E04B 700

US Classification:

52478

Abstract:

A reinforcing plate for use underneath two or more lapped thin gauge sheets to stiffen the lapped joint for prevention of damage to the seal from loading and to provide uniform compressant of sealant between the lapped sheets. The plate comprises an elongated planar member having pairs of parallel cuts evenly spaced along its length extending transversely from one edge thereof for substantially one half its width, the material between each of the pairs of cuts being bent into a down turned mounting flange of L-shaped cross section.

International Classification:

A61B 500
B65D 8100

US Classification:

600573

Abstract:

A fluid collection apparatus is provided for controlling fluid communication between a vacuum source and first and second vacuum lines of a surgical device such as a core sampling biopsy device. The fluid collection apparatus comprises first and second fluid lines adapted for detachably connecting to, and in fluid communication with, the first and second vacuum lines, respectively, of the surgical device. The fluid collection apparatus further comprises first and second valves in fluid communication with first and second fluid lines, respectively. Each of first and second valves has an open position and a closed position. The fluid collection apparatus further comprises an air vent selectively communicating with first and second vacuum lines, and a valve frame for fixing first and second valves relative to each other, where the valve frame has a latching means for detachably connecting the valve frame to the surgical device.
