More Information
Summary:A device for introducing fluids into the lumen of a body duct comprises an elongate shaft having a mechanism at its distal end for capturing the duct. A needle is disposed within an axial passage in the shaft, and a mechanism for reciprocating the needle is located at the proximal end of the shaft. In this way, the duct can be captured with the capture mechanism and pierced with the needle. The fluid is then provided to the lumen of the duct through a perfusion port located at or near the distal end of the needle. Optionally, a mechanism for applying a vacuum externally to the duct within the capture mechanism is provided to help hold the duct and open the interior to facilitate introduction of the fluid.
