Abstract: An insertion device for use in assisting with the placement of a medical device within the body of a patient is disclosed. For example, the insertion device can be employed to assist with the placement of an introducer, which provides a conduit for insertion of a catheter into the body. In one embodiment, the insertion device comprises a needle that is removably disposed within a bore defined by the medical device, and a needle retraction assembly. The needle retraction assembly can position the needle in any one of a first position wherein a distal tip of the needle is disposed a predetermined distance distal to a distal end of the medical device, a second position wherein the needle distal tip is disposed distal but proximate to the distal end of the medical device, and a third position wherein the needle distal tip is retracted within the medical device bore.

Abstract: A multi-lumen catheter including an elliptical cross-sectional profile configuration that enhances fluid flow rate while minimizing the average diameter of the catheter body is disclosed. In one embodiment the catheter comprises an elongate catheter tube defining a plurality of lumens. At least a portion of the longitudinal length of the catheter tube defines an elliptical cross section, in turn defined by a major axis and a minor axis. A ratio of the major axis to the minor axis of the elliptical catheter tube cross section is between about 1.3 and about 1.4 in one embodiment. The catheter body can define two, three, or more lumens, in one embodiment.

Abstract: An insertion tool for inserting a catheter into a body of a patient is disclosed. The insertion tool unifies needle insertion, guidewire advancement, and catheter insertion in a single device. In one embodiment, the insertion tool comprises a housing in which at least a portion of the catheter is initially disposed, a hollow needle distally extending from the housing with at least a portion of the catheter pre-disposed over the needle, and a guidewire pre-disposed within the needle. A guidewire advancement assembly is also included for selectively advancing the guidewire distally past a distal end of the needle in preparation for distal advancement of the catheter. In one embodiment a catheter advancement assembly is also included for selectively advancing the catheter into the patient. Each advancement assembly can include a slide or other actuator that enables a user to selectively advance the desired component.
