Systems and Methods for Needle for Subclavian Vein Penetration

摘要

Systems and methods for placement of an introducer needle into the subclavian vein. A needle for subclavian vein penetration includes a straight needle portion, a bent needle portion, and a hub. The bent portion allows for needle placement with minimized chance of complications. The needle and hub form a lumen through which a guide wire can be placed. The bent needle portion has an inner diameter substantially similar to the inner diameter of the straight needle portion to reduce resistance due to movement of the guide wire.

主权项

1. A needle for subclavian center line catheter placement, the needle comprising:
a proximal needle portion corresponding to a straight hub and formed of a rigid material, the straight hub having an outside diameter, a hollow interior, and a length, and having a first end configured to be coupled to a syringe and a second end; and a needle shaft portion formed of a high hardness metal, said needle shaft portion having a first straight end rigidly affixed to a portion of the hollow interior of the straight hub, the first straight end of the needle shaft portion having: an embedded section having a length of about 0.375″ which extends at least partially through the hollow interior of the straight hub with at least a portion of the embedded section forming a friction fit within the straight hub portion; and an exposed section extending distally beyond the second end of the straight hub, the exposed section having a length of about 2.5″ and an outside diameter of about 18 gauge and the exposed section of the needle shaft portion having a bent shaft portion proximate the second end of the straight hub and a straight shaft portion distal of the bent shaft portion with the bent shaft portion forming an angle of about 30 degrees from a central longitudinal axis of the straight hub such that the straight shaft portion of the needle may be inserted into a subclavian vein without a body of a patient interfering with movement or position of the hub wherein the inner diameter of the bent portion is substantially similar to the inner diameter of the straight shaft portion.
