    • A needleless fluid injection system include a working shaft (14) with a proximal end and a distal end, an injection shaft with a proximal end and a distal end, and a tissue tensioning mechanism (40) 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 one or more of multiple radially expanding arcuate members (44), a linearly compressible element (60) with first and second plates at opposite ends of the linearly compressible element, an arcuate member (70) having a first end engaged within the lumen of the injection shaft and a second end moveable relative to the first end, first and second wedges (90a, b) that are slideable relative to each other, an inflatable bladder (110) with a foam material within a body opening of the bladder, at least two electromagnetic coils (146,148), or an electroactive polymer portion (166).

    • Laser radiation delivered to a treatment area causes vapopzation of a substantially greater volume of tissue than the volume of residual coagulated tissue The laser radiation may have a wavelength of about 300 m to about 700 nm, may be used with a smoke suppressing irpgant, may have an average irradiance greater than about 5 k?lowatts/cm2, and may have a spot size of at least 0 05 mm2 A laparoscopic laser device, for use with an insufflated bodily cavity, may include an elongate body adapted for insertion into an insufflated bodily cavity A laser energy delivery element, at the distal end of the elongate body, may be coupleable to a source of tissue-vapopzation-capable laser energy and capable of delivepng laser energy along a laser energy path extending away from the laser energy delivery element A smoke-suppressing liquid pathway extending along the elongate body may be coupleable to a source of a smoke-suppressing liquid
    • 传递到治疗区域的激光辐射导致显着更大量的组织的蒸发,而不是残留的凝固组织的体积。激光辐射可以具有约300μm至约700nm的波长,可以与烟雾抑制剂一起使用,可以具有 平均辐照度大于约5kΩ/ cm 2,并且可以具有至少0.05mm 2的光斑尺寸。用于与吹入的体腔一起使用的腹腔镜激光装置可以包括适于插入到吹入的身体内的细长体 空腔在细长本体的远端处的激光能量输送元件可以可耦合到具有组织膨胀能力的激光能量的源并且能够沿远离激光能量输送元件A延伸的激光能量路径输送激光能量 沿着细长主体延伸的抑烟液体路径可以连接到抑烟液体源
