Abstract

Claims (21)

1. A catheter placement system, comprising:

a housing defining an interior cavity and configured to maintain a sterile environment therein;

a catheter comprising:

a catheter tube having a first section, a second section, and a transition section disposed therebetween, one or both of the transition section and the second section disposed within the sterile environment defined by the housing;

a hub supporting a proximal end of the second section;

a first extension leg extending proximally from the hub and communicating with a first lumen of the catheter tube; and

a second extension leg extending proximally from the hub and communicating with a second lumen of the catheter tube;

a needle extending through a distal portion of the first lumen; and

a stiffening system comprising:

a first stylet comprising a first stylet lumen positioned in a proxmial portion of the first lumen; and

a second stylet comprising a second stylet lumen and a stylet guidewire, a proximal end of the stylet guidewire coupled to a distal end of the second stylet, the second stylet positioned in a proximal portion of the second lumen, the stylet guidewire extending through the hub into the second section.

2. The catheter placement system according to claim 1 , wherein the needle extends through a first side port of the catheter into a distal portion of the first lumen, a distal portion of the needle and a distal portion of the first section extending from a distal end of the housing.

3. The catheter placement system according to claim 2 , further including a needle retraction assembly configured to withdraw the needle proximally from the first lumen and dispose the needle in an offset position from an axis of the first lumen within the interior cavity.

4. The catheter placement system according to claim 2 , further including a first guidewire advancement assembly configured to advance a first guidewire through the first side port of the catheter and through a distal portion of the first lumen.

5. The catheter placement system according to claim 4 , further including a second guidewire assembly including a scroll wheel actuator configured to rotate and advance a second guidewire through the first lumen.

6. The catheter placement system according to claim 1 , wherein the stiffening system further includes a third stylet comprising a third stylet lumen and a second stylet guidewire, a proximal end of the second stylet guidewire coupled to a distal end of the third stylet, the third stylet positioned in a proximal portion of a third lumen of the catheter, the second stylet guidewire extending through the hub into the second section of the catheter.

7. The catheter placement system according to claim 6 , wherein the second lumen communicates with a distal opening disposed in a sidewall of the second section, a distal portion of the stylet guidewire configured to selectively occlude the distal opening.

8. The catheter placement system according to claim 1 , further including a catheter advancement assembly configured to advance the catheter distally, and configured to separate a top half of the housing from a bottom half of the housing when advanced to a distal position.

9. The catheter placement system according to claim 1 , further including a manifold including a flushing hub in fluid communication with one or both of the first stylet lumen and the second stylet lumen, the manifold configured to support the stiffening system.

10. The catheter placement system according to claim 2 , further including a blood flash indicator disposed within the interior cavity and in fluid communication with a lumen of the needle.

11. The catheter placement system according to claim 1 , wherein the second stylet defines a more rigid mechanical characteristic relative to the stylet guidewire.
