Gene therapy platformed needle and method of administering a therapeutic solution to a heart

摘要

The invention provides a device for the delivery of a therapeutic solution, in particular, an angiogenesis-promoting substance into a heart. The device includes an elongated needle (10) having a stop, or platform (44), spaced from the distal needle tip (42) to limit the depth of penetration and stabilize the needle in the cardiac tissue. The elongated needle body (30) is flexible enough to maneuver around thoracic and cardiac geometry, yet sufficiently rigid to facilitate such maneuvering. This minimally invasive procedure allows for delivery of the solution "at a distance" through small incisions.
