    • Methods and apparatuses for deploying percutaneous probes. An apparatus in accordance with one embodiment of the invention includes a housing (4) and a percutaneous probe having a sharp end (2) and positioned within the housing (4). The percutaneous probe is movable relative to the housing between a stowed position and at least one of a first deployed position and a second deployed position. The percutaneous probe (1) can project from the housing through aperture (5) by a first distance when in the first deployed position and a second distance greater than the first distance when in the second deployed position. A depth control device can operatively couple to the percutaneous probe and can have a first configuration to allow the percutaneous probe to be moved to the first deployed position and a second configuration to allow the percutaneous probe to be moved to the second deployed position.
    • 用于部署经皮探针的方法和装置。 根据本发明的一个实施例的装置包括壳体(4)和具有尖端(2)并定位在壳体(4)内的经皮探针。 经皮探针相对于壳体在收起位置和第一展开位置和第二展开位置中的至少一个之间是可移动的。 当处于第一展开位置时,经皮探针(1)可以从壳体通过孔(5)突出第一距离,并且当处于第二展开位置时,经皮探针(1)可以从第一距离大于第一距离。 深度控制装置可以可操作地耦合到经皮探针并且可以具有第一构造以允许经皮探针移动到第一展开位置和第二构造以允许经皮探针移动到第二展开位置。
