摘要：A needleless fluid injection system include a working shaft () with a proximal endand a distal end, an injection shaft with a proximal end and a distal end, and a tissuetensioning mechanism () positioned at the distal end of at least one of the working shaft

and the injection shaft. Embodiments of the tissue tensioning mechanism can include oneor more of multiple radially expanding arcuate members (), a linearly compressibleelement () with first and second plates at opposite ends of the linearly compressibleelement, an arcuate member () having a first end engaged within the lumen of theinjection shaft and a second end moveable relative to the first end, first and secondwedges (, b) that are slideable relative to each other, an inflatable bladder () with a foammaterial within a body opening of the bladder, at least two electromagnetic coils (), or anelectroactive polymer portion ().
