Zusammenfassung:Needleless injection device components, systems, and methods that involve features including an elongate shaft that has a working shaft comprising a working shaft proximal end, a working shaft distal end, and a working lumen extending between the working shaft proximal end and the working shaft distal end, an injection shaft including an injection shaft proximal end, an injection shaft distal end, and a needless injection orifice disposed through the sidewall at the injection shaft distal end, the injection shaft moveably disposed within the working lumen, and a tissue tensioner secured to the injection shaft at the injection shaft distal end and moveable relative to the working lumen, the tissue tensioner having an expandable surface capable of exhibiting an expanded state and a non-expanded state, the tissue tensioner in the expanded state being capable of tensioning luminal tissue for injection by the needless injection orifice.
