摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A medical device for severing and removing small amounts of internal tissue for biopsy sampling or other purposes is disclosed. Versions of the device may include a hollow probe having a piecing tip, a tissue receiving aperture and a vacuum lumen; a cutter within the probe having a cutting edge that moves past the tissue receiving aperture, and a cutter driver mechanism. A cutter for use with versions disclosed herein may include an angled cutting tip and a cutting edge having a concave grind. Versions of the device also may include an aspirator fluidly connected to the vacuum lumen, coordinated operation of the aspirator and the cutter driver mechanism, and a fluid management system. Versions described may be used for removing multiple samples of tissue during a single insertion of the probe proximate to a target tissue mass.
