A biopsy device comprises a body and a needle extending distally from the body. The needle comprises a cannula and a tissue piercing tip that is unitary with the cannula. The tissue piercing tip may be formed by compressing the distal end of the cannula to put two distal cannula portions in apposition with each other. One of the apposed distal cannula portions may be removed. The remaining distal cannula portion may be formed into a blade of the tissue piercing tip. A cutter may be moved relative to the needle to sever samples from tissue protruding through a transverse aperture formed in the cannula. A gap may be provided between the exterior of the cutter and the interior of the cannula, permitting the cutter to be distally vented while a proximal vacuum is communicated to the cutter to transport severed tissue samples proximally through the cutter.

Biopsy device

Bowel retractor devices. In various forms, the bowel retractor devices are configurable from a collapsed position wherein the retractor may be inserted through a trocar cannula or other opening in a patient's body to a second expanded position wherein at least a portion of the patient's bowel may be advantageously supported in a desired position.

Surgical bowel retractor devices

Tissue manipulation devices are disclosed. In various forms, the devices include tissue manipulation arms that are arranged in a position suitable to enable the device to be inserted into the colon then, upon application of at least one actuation motion thereto, at least some of the tissue manipulation arms are moved to deployed positions wherein they contact corresponding portions of the colon to thereby expand the colon. Various devices are actuatable by various forms of actuation forces. In various embodiments, the tissue manipulation arms may be movable along corresponding axes that are transverse to an insertion axis and may also be rotated about the insertion axis as well as be moved in directions that are substantially parallel to the insertion axis.

Needle for biopsy device

A biopsy device includes a body having a cannula, a cutter positioned at least partly within the cannula, a tissue collection chamber, and a vacuum source. In one example, the biopsy device includes a cutter loader for rotating the cutter into a loaded position (e.g., open position). A trigger is engaged with a portion of the cutter loader and may be activated to allow the cutter to rotate back to a closed position. During this rotation, the cutter severs a tissue sample, which may thereafter be drawn through the cutter lumen into the tissue collection chamber under the influence of a vacuum created by the vacuum source. The vacuum source includes a piston configured to be operated by squeezing a scissors grip. A user may apply a single stroke or successive strokes to the piston to produce the vacuum.
