A deep vein intravenous introducer has a wheel located toward the front end of the device that can be rotated by the index finger of the user. After placement of the needle in the lumen of the vessel, the user rotates the wheel, which turns a drive wheel. The drive wheel has an outer surface that advances the guide wire through the center of the needle and into the patient. Once the guide wire is advanced into the vessel lumen the catheter can be advanced over the guide wire with a hub or finger tab on the catheter close to the index finger. The operation can be performed by one hand without moving the hand from its initial position.

After placement of the needle in the lumen of the vessel, the user rotates the wheel, which advances the wire guide through the center of the needle and into the patient. Once the guide wire is advanced into the vessel lumen the catheter can be advanced over the guide wire with a hub or finger tab on the catheter close to the index finger. The operation can be performed by one hand without moving the hand from its initial position. The user can then simultaneously use the other hand to operate an ultrasound detection device during insertion without the assistance of another person.

Ultrasound assisted catheter placement system

The invention describes methods for producing a biphasic nanocomposite scaffold comprising custom polymer-based core-shelled nanospheres by the physical and chemical attachment of two disparate polymeric materials whose composition can be readily modified with tissue-specific nanomaterials and products created using such methods. The custom nanospheres are constructed via co-axial wet electrospraying and can be employed to deliver compounds to the polymeric materials.

Wire introduction device for introducing guide wire

A deep vein intravenous introducer has a wheel located toward the front end of the device that can be rotated by the index finger of the user. After placement of the needle in the lumen of the vessel, the user rotates the wheel, which advances the wire guide through the center of the needle and into the patient.

The operation can be performed by one hand without moving the hand from its initial position. The user can then simultaneously use the other hand to operate an ultrasound detection device during insertion without the assistance of another person. A catheter is provided that can be visualized by ultrasound to enable confirmation of correct placement in a vessel.
