Abstract

Methods and apparatuses for deploying percutaneous probes. An apparatus in accordance with one embodiment of the invention includes a housing and a percutaneous probe having a sharp end and positioned within the housing. 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 can project from the housing 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.
