Biopsy Device With Variable Side Aperture
View pageUS Patent:
7517322, Apr 14, 2009
Filed:
Mar 4, 2005
Appl. No.:
11/072719
Inventors:
Lee E. Reichel - Springboro OH, US
John A. Hibner - Mason OH, US
Michael R. Ludzack - Maineville OH, US
John A. Hibner - Mason OH, US

Assignee:
Ethicon Endo-Surgery, Inc. - Cincinnati OH
International Classification:
A61B 10/00
US Classification:
600566, 600567, 600568, 606171
Abstract:
A biopsy device and method are provided for obtaining a tissue sample, such as a breast tissue biopsy sample. The biopsy device may include an outer cannula having a distal piercing tip, a cutter lumen, a side tissue port communicating with the cutter lumen, and at least one fluid passageway disposed distally of the side tissue port. The inner cutter may be advanced in the cutter lumen past the side tissue port to sever a tissue sample. After the tissue sample is severed, and before the inner cutter is retracted proximally of the side tissue port, the cutter may be used to alternately cover and uncover the fluid passageway disposed distally of the side tissue.

Assignee:
Ethicon Endo - Surgery, Inc. - Cincinnati OH
International Classification:
A61B 17/10
US Classification:
2271752, 2271761, 2271754, 227 19, 2271781
Abstract:
A linear surgical stapler adapted for applying a plurality of surgical fasteners to body tissue includes an anvil structure and a cartridge housing containing a plurality of surgical fasteners. The cartridge housing and anvil structure are relatively movable between a first spaced apart position and a second position in close approximation with one another. A firing mechanism is associated with the cartridge housing for ejecting the surgical fasteners from the cartridge housing to be driven against the anvil structure. A lockout mechanism interacts with the cartridge housing for selective activation and deactivation. The lockout mechanism includes a swing gate tab secured to the cartridge housing at a position adjacent a lockout lever, such that firing of the linear surgical stapler rotates the swing gate tab releasing the lockout lever for preventing further firing of the used cartridge housing.

Biopsy Device With Sliding Cutter Cover
View pageUS Patent:
7846109, Dec 7, 2010
Filed:
Dec 18, 2008
Appl. No.:
12/337674
Inventors:
Shailendra K. Parihar - Mason OH, US
Michael R. Ludzack - Maineville OH, US
Michael R. Ludzack - Maineville OH, US
Assignee:
Devicor Medical Products, Inc. - Cincinnati OH
International Classification:
A61B 10/00
A61B 17/32
A61B 17/32
US Classification:
600567, 600562, 600564, 606167, 606170
Abstract:
A biopsy device comprises a targeting set, a probe assembly, and a holster assembly, which are detachable from one another. The targeting set comprises a needle assembly having a tissue piercing tip and tissue receiving aperture. The probe assembly comprises a tissue cutter, a body, cutter driving mechanism components, and a sliding cutter cover. The cutter extends from a distal portion of the probe assembly. The sliding cutter cover extends from the distal portion of the probe assembly when the probe assembly is detached from the needle assembly of the targeting set assembly. This extension of the sliding cutter cover shields a user of the biopsy device from the sharp cutter. The sliding cutter cover further retracts into the probe assembly when the probe assembly is coupled with the needle assembly of the targeting set assembly. The cover may be resiliently biased to extend distally from the probe assembly.
Method Of Manufacturing A Needle Assembly For Use With A Biopsy Device

International Classification:
B23P 25/00
B05D 3/00
B05D 3/00
US Classification:
29458, 427 212
Abstract:
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.

Assignee:
Devicor Medical Products, Inc. - Cincinnati OH
International Classification:
A61B 10/00
US Classification:
600568
Abstract:
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. External vacuum holes along the outer cannula (probe) that communicate with a vacuum and cutter lumen withdraw bodily fluids while a hemostatic disk-shaped ring pad around the probe applies compression to an external hole in the skin and absorbs fluids.

International Classification:
A61B 10/00
US Classification:
600567, 600562, 600564, 600566
Abstract:
A biopsy device targeting set includes a vertical member, a carriage that is vertically movable along the vertical member, and a cradle coupled with the carriage. The cradle has a pair of substantially perpendicular mounting arms. Each mounting arm has a recess that may receive a rail of the carriage, such that the cradle may be mounted to the same rail in different orientations. Each mounting arm also has a biopsy device mounting feature, which may be a recess or a rail. The biopsy device mounting feature is configured to engage with a complementary feature of a biopsy device, such that a biopsy device may be mounted to either mounting arm. A z-stop feature is operable to selectively restrict longitudinal motion along either or both of the biopsy device mounting features. The targeting set may be used with a biopsy device in an MRI environment.
