摘要： A method of biopsy device operation comprises rotating a first rotating member at a first rotational speed to rotate a cutter. A second rotating member is rotated at a second rotational speed to translate the cutter. The first and second members are rotated simultaneously and in the same direction. The first rotating member rotates with the cutter, while the second rotating member rotates about the first rotating member. The difference between the first and second rotational speeds, as well as threaded engagement between the first and second rotating members, provides the translation of the cutter. A method of biopsy device operation also comprises moving a shuttle valve slider to selectively vent or seal the second lumen of a needle. The shuttle valve slider is responsive to translation of the cutter, though some degree of lost motion is provided between the shuttle valve slider and the cutter.

摘要： An intravenous catheter introducer assembly having a safety feature to prevent accidental needle sticks. The introducer assembly includes a needle assembly having a groove disposed on its outer surface. The introducer includes a protector made of a hollow member having an open distal end and an inwardly disposed resilient flange or a clip disposed thereon. The protector is coaxially slidably disposed around the needle with the flange abutting the outer surface of the needle and adapted to engage the groove when a catheter assembly is removed from the needle.

摘要： A biopsy device includes a cannula, a cutter disposed within the cannula, a needle hub having a gear for rotating the cannula, a mechanism for rotating and translating the cutter within the cannula, and a body portion. The cutter rotation and translation mechanism includes a first component that is secured to the cutter and a second component that is secured to the body portion. The body portion includes a tab that is configured to retain the axial position of the cannula and needle hub relative to the body until the tab is depressed or removed. The body is configured to permit the cannula and the needle hub to be pulled axially from the body only after the tab has been depressed or removed. The cutter can then be pulled axially from the body by unscrewing the first component of the cutter rotation and translation mechanism from the second component.

摘要： A biopsy device includes a cutter defining a cutter lumen and a tissue sample holder for collecting tissue samples. In one example, the tissue sample holder has a rotatable manifold that is configured to redirect fluid from one axial direction to an opposite axial direction. The tissue sample holder also has a plurality of tissue sample trays through which fluid may be communicated. The tissue sample trays define chambers that are each configured to separately hold tissue samples. The tissue sample trays are removable relative to the manifold. A cup is configured to cover the manifold and trays. A tissue sample holder rotation mechanism is operable to rotate the manifold to successively index each chamber of the tissue sample trays with the cutter lumen. A feature may prevent rotation of the manifold when one part of the biopsy device is separated from another part of the biopsy device.
