Abstract: A device for collecting a tissue sample includes a needle body extending along a longitudinal axis from a proximal end to a distal end and including a channel extending longitudinally therethrough and a plurality of cut outs extending laterally into the needle body, each of the plurality of cut outs extending at an angle relative to the longitudinal axis from an outer surface of the needle body toward the distal end thereof so that the channel is open to an exterior of the needle body via the plurality of cut outs.

Abstract: A medical device including an outer balloon, an inner balloon, and at least one delivery unit is disclosed. The outer balloon defines a first internal cavity that remains in fluid communication with a first inflation lumen. The inner balloon is disposed within the first internal cavity, and defines a second internal cavity that is in fluid communication with a second inflation lumen. Each delivery unit includes at least one needle configured to pierce a tissue and at least one reservoir containing a material. Further, inflation of the outer balloon or the inner balloon is structured and arranged to deliver the material into the tissue through the needle lumen.
