Abstract

A syringe includes a barrel and a rotatable element on the barrel, for example, at a proximal location along the length of the barrel. The rotatable element rotates at least partially around the barrel. When a handle is associated with the rotatable element, the barrel may rotate as the handle is held substantially stationary or the handle may be rotated while the barrel and any peripheral device secured thereto remain substantially stationary. When handles are associated with a rotatable element that may be removed from a barrel, a barrel that is disassembled from the rotatable element may be replaced with another barrel of the same or a different configuration. The barrel and plunger may be configured to cause the barrel to rotate as the plunger moves along the length of the barrel. Methods of using a syringe with a rotatable element on a barrel thereof are also disclosed.

Claims

1. A method for using a syringe comprising:

securing a device to a barrel of the syringe;

grasping a handle associated with a rotatable element on the barrel; and

actuating the handle to;

force a plunger longitudinally through the barrel; and

cause the barrel to rotate about a longitudinal axis of the barrel and the device to rotate about the longitudinal axis of the barrel while the handle is held in a substantially stationary rotational position relative to the longitudinal axis of the barrel.

2. The method of claim 1, wherein:

securing the device to the barrel comprises securing a biopsy needle to the barrel; and

actuating the handle facilitates;

coring of a sample with the biopsy needle; and

aspirating the sample into at least the biopsy needle.

3. The method of claim 1, wherein:

securing the device to the barrel comprises securing a catheter to the barrel; and

actuating the handle causes;

rotation of the catheter about an axis extending along a length of the catheter; and

aspirating a sample into the barrel.

4. The method of claim 1, wherein actuating the handle comprises drawing the plunger proximally through the barrel.

5. The method of claim 4, wherein actuating the handle comprises forcing aspiration handles together.

6. The method of claim 1, wherein actuating the handle comprises forcing the plunger distally through the barrel.

7. The method of claim 6, wherein actuating the handle comprises forcing injection handles together.
