Fluid delivery devices for the direct delivery a fluid or drug into a vessel, such as a coronary vessel on a beating heart. One device generally includes an elongate cannula having a proximal end, a distal end, and at least one lumen extending between the proximal end and the distal end of the cannula. A connector is coupled adjacent to the proximal end of the cannular defining at least a first lumen and a second lumen. At least the first lumen of the connector extends coaxially with and is in fluid communication with the lumen of the cannula. An insertion needle having a sharp distal end, is movably disposed lengthwise in the first lumen and the lumen of the cannula. A flexible elongate tubular body is operatively coupled to and in fluid communication with the second lumen of the connector. |
