Injectate delivery devices, systems and methods

An injectate delivery device for expanding tissue comprising:

• a body having an outer surface;
• a first tissue capture port,
• a second tissue capture port, and
• a third tissue capture port disposed on the body in a circumferential array and positioned approximately 120° apart, each tissue capture port comprising an opening through the outer surface configured to capture tissue within the opening when a vacuum is applied to the tissue capture port;
• a first vacuum lumen fluidly coupled to the first tissue capture port,
• a second vacuum lumen fluidly coupled to the second tissue capture port, and
• a third vacuum lumen fluidly coupled to the third tissue capture port;
• for each tissue capture port, a fluid delivery tube having a lumen and a fluid delivery element in fluid communication with the lumen of the fluid delivery tube, the fluid delivery element slidably disposed within the tissue capture port, wherein the fluid delivery element comprises a collar, and wherein the tissue capture port comprises a distal stop and a proximal stop, the distal stop and the proximal stop positioned to abut the collar to limit travel of the fluid delivery element between a distal-most position and a proximal-most position;
• a compression element operably connecting at least one of the fluid delivery tubes to a control, the compression element constructed and arranged to limit force applied to the fluid delivery tube during advancement of the fluid delivery element;
• and
• wherein the injectate delivery device is configured to deliver an injectate to target tissue through the fluid delivery elements.
