  • Apparatus for preventing loss of a composition during a medical procedure
    Publication number: 20010027296
    Abstract: In a method and apparatus for delivering a composition to a targeted area of tissue, exposure of a non-targeted tissue to the composition is minimized. The apparatus has at least one needle-like shaft which is inserted through a track in the non-targeted tissue to deliver the composition to the targeted tissue through an opening in the shaft. The track may be a naturally occurring lumen in a tissue, such as a vascular lumen, or may be a track created surgically by a diagnostic instrument, or by the needle-like shaft of the present apparatus. A valve-like mechanism closes the opening in the shaft to prevent premature delivery of the composition during insertion of the shaft, and to prevent loss of composition during withdrawal of the shaft. The valve-like mechanism also prevents excessive delivery of the composition to targeted tissue. An annular dam is mounted on an exterior portion of the shaft near the opening.
