Abstract
An apparatus provides targeted placement of openings for infusing fluids into a body. The apparatus provides a driving force to a penetrating medical device, such as a needle, when the apparatus tip encounters material of high resistance. When the apparatus tip encounters a low resistance material, no further driving force is applied to the apparatus due to contraction of an element made of interlaced flexible elements. A multi-opening needle is provided in some embodiments wherein placement of one of the openings in a target region with a relatively lower external pressure allows pressurized fluid to exit the needle while openings remaining in higher pressure, non-target regions do not release substantial amounts of the fluid.
