In one embodiment of the present disclosure, a catheterization system is disclosed that includes a catheter including a body with proximal and distal ends and defining first and second lumens extending therethrough, and a stylet. The stylet includes first and second stylet portions each having proximal and distal end regions, wherein the distal end regions of the first and second stylet portions together define a tapered penetrating portion. The first and second stylet portions are configured and dimensioned to be slidably positioned within the first and second lumens of the catheter, respectively. The first and second stylet portions extend from the proximal end of the catheter and beyond the distal end of the catheter, and are independently movable in relation to each other to facilitate selective removal of the first stylet portion and/or the second stylet portion from the catheter. | 12-30-2010 |
20110202007 | Slittable or Removable Valves and Apparatus and Methods for Making and Using Them - A system and/or apparatus for delivering a medical device into a body includes an elongate tubular member and a valve fitted within a proximal end thereof. The valve preferably includes a tubular body and a flap, wherein the tubular body is engaged within the proximal end of the tubular member and has an open end approximately aligned with a proximal termination of the proximal end of the tubular member. The flap of the valve preferably extends over a hole formed in an end wall of the tubular body opposite a side of the end wall that faces a passage of the tubular body, which passage extends between the open end and the end wall. The hole communicates with the passage and with the lumen of the tubular member, and the flap is movable away from the hole when the device is introduced through the passage and the hole. | 08-18-2011 |
20120059321 | TUNNELER FOR BI-DIRECTIONAL TUNNELING - A tunneler for producing a subcutaneous tunnel in connection with the placement of a catheter within a body of a patient is disclosed. In one embodiment, the tunneler comprises an elongate tunneler member and a sheath. The tunneler member includes a handle on its proximal end and a tapered distal end. The sheath defines an elongate lumen inside which the tunneler member is initially received. The tunneler member is configured to define a tunnel through subcutaneous tissue while disposed in the sheath, then is removable from the sheath lumen thereafter. The sheath is configured to remain within the tunnel so that a catheter can be inserted through the sheath within the tunnel. The sheath is splittable in one embodiment so as to enable its removal from the tunnel while leaving the catheter in place. | 03-08-2012 |

An introducer for the implantable member is received in a passageway of the dilator and extends along a length of the dilator to the tapered distal end. The introducer is arranged relative to the dilator such that upon a relative proximal movement of the dilator, the tapered distal tip of the dilator splits whereby the distal end of the introducer extends therethrough. A handle has a gripping mechanism for engagement with each tab for initiating proximal movement of the dilator relative to the introducer upon rotation of the gripping mechanism. The handle is structured for splitting the dilator proximal portion upon the relative proximal movement of the dilator. | 02-28-2013 |
