DEVICES AND METHODS FOR CONTROLLED-DEPTH INJECTION |
摘要 |
Devices and methods for limiting the depth to which a penetrator is advanced into an organ or mass of tissue. The device generally comprises a first member and a second member. The penetrator is attached to and extends from a second member. The first member has a penetrator shroud and a hollow bore extending therethrough. The second member is engageable with the first member such that a distal portion of the penetrator extends through the penetrator shroud. The distance to which the penetrator protrudes out of and beyond the distal end of the penetrator shroud is adjustable in accordance with the desired depth of penetration. The penetrator may then be advanced into the organ or tissue mass until the distal end of the shroud abuts against the organ or tissue mass, thereby stopping further advancement of the penetrator. The penetrator may have one or more lumen(s) for aspirating or infusing substances. |
