A biopsy device includes a needle extending distally from a body. The needle includes a transverse aperture, a first lumen, and a second lumen. A cutter is movable within the first lumen to sever tissue protruding through the transverse aperture. A valve assembly is operable to change the pneumatic state of the second lumen. The valve assembly includes a valve body and a translating member slidably disposed in a bore of the valve body. The valve body includes a first port and a second port. The first port is in fluid communication with the second lumen of the needle. The second port is in fluid communication with atmospheric air. The translating member selectively couples the first port with the second port based on the longitudinal position of the translating member within the bore. The translating member translates relative to the valve body based on the position of the cutter.

Biopsy device with translating valve member

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.

Biopsy device with variable side aperture

A needle assembly comprises an outer cannula and an inner cannula. The outer cannula and the inner cannula have complementary tissue receiving apertures. A tissue piercing tip is secured relative to one or both of the inner cannula or the outer cannula. A cutter is slidably disposed in the inner cannula. The cutter is configured to sever tissue protruding through the transverse apertures. A hub releasably secures at least part of the needle assembly relative to the body of a biopsy device.

Needle assembly for use with a biopsy device

A biopsy device includes a body portion, a tip, at least one blade, and a cutter. The cannula defines at least one lumen. The cannula has a transverse aperture configured to receive tissue. The tip is located at the distal end of the cannula, and may include at least two concave surfaces. The blade extends longitudinally from the tip. A second blade may also extend longitudinally from the tip. Blades may be axially staggered relative to the cannula. Blades may also have lengths that differ from one another. In addition, a blade may have a pointed distal end, or may have a curved distal edge. The configuration of the blade and tip may provide reduced force to penetrate tissue. The blade and tip may produce a cut length that is greater than or equal to the length of the outer perimeter of the cannula.

Needle tip for biopsy device

An ultrasonic medical instrument having a handpiece and medical ultrasonic blade assembly including a vibration antinode, a handpiece, and a medical ultrasonic blade. The blade is threadably engaged by the handpiece proximate the vibration antinode. The blade is in ultrasound-transmitting physical contact with the handpiece proximate the vibration antinode and apart from where the medical ultrasonic blade is threadably engaged by the handpiece. A medical-instrument connection assembly for transmitting ultrasonic vibrations includes first, second, and third connecting members. The first connecting member is adapted to be ultrasonically vibrated and has a longitudinal axis. The second connecting member is capable of being positioned to be substantially coaxially aligned with the longitudinal axis and in ultrasound-transmitting physical contact with the first connecting member. The third connecting member surrounds, and is rotatably or fixedly attached to, the second connecting member and is threadably engageable with the first connecting member.

An apparatus for inserting a marking element into a marker body includes a body portion, an insertion member, and a pushing member. The body portion has a compartment configured to receive a marker body. The insertion member is configured to engage the marker body within the compartment. The pushing member is configured to engage with the insertion member. The pushing member is operable to force a marking element along the insertion member into the marker body. The insertion member may include a hollow needle configured to penetrate the marker body. The pushing member may include a pin configured to fit within the hollow needle. The marker body may include an opening such as a slit, a slot, or a passage that is configured to receive a marking element. The marker body may include a collagen dowel, and the marking element may be formed of titanium.

Method and apparatus for inserting biopsy site marker in marker body

An instrument for deploying a marker at a site within a patient may include an elongate cannula, an elongate pusher, and a marker disposed within the cannula. The cannula may have a tip at its distal end and a transverse opening. The pusher may be disposed within the cannula, and may be moved longitudinally within the cannula. The pusher may have a ramped distal end. The marker may be configured to exit the transverse opening upon urging by the ramped distal end of the pusher. In some versions, the tip of the cannula has a flat proximal face, and the marker has a recessed region that is configured to buckle in response to longitudinal compression, such that the marker will pop out of the cannula upon buckling. In other versions, the cannula has an external sheath, an open and curved distal end, or a leaf spring.

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.
