    摘要： A catheter device that is useable to extract material from a body conduit, such as a blood vessel, comprises a flexible catheter advanceable into the body conduit, an opening in the wall of the catheter that is in fluid communication with a material collection chamber, and a controllably arcuate segment along the catheter shaft, near the distal tip of the catheter and including the opening. Further said catheter may include a sliding member, located within a lumen of the catheter, that is used to move the material entering the catheter through the arcuate segment opening, into the material collection chamber and away from said opening. The catheter may include a single mechanism utilized to both generate a vacuum to cause material to enter the catheter at the arcuate segment opening and also cause the sliding member to travel, inside the catheter, moving material away from the opening and into the material collection chamber. Methods of utilizing such a catheter device to remove material from a body conduit are also disclosed.

    摘要： A transcutaneous access tool includes a first cannula moveable along an axis, a fixed member including an elongated prong extending parallel with the axis, and a deployment member secured to the first cannula and movable along the axis away from the fixed member. The deployment member includes spaced-apart, resiliently flexible fingers extending parallel with the axis and having distal ends that are laterally enlarged with respect to the axis. The resiliently flexible fingers are received on the prong of the fixed member. A second cannula is disposed within the lumen of the first cannula, and retraction member is secured to the second cannula and is movable along the axis. The retraction member includes at least one catch catching on the laterally enlarged distal ends of the fingers of the deployment element when the fingers are laterally held apart by the prong of the fixed member.
