Abstract:
1. A percutaneous insertion system, comprising: a needle assembly having a proximal end, a distal end, and a passageway extending therebetween, the distal end comprising an elongated needle for percutaneous entry into a body vessel for withdrawing a body fluid therefrom, and the proximal end comprising a needle hub; a needle hub attachment assembly having a proximal end, a distal end, and a passageway extending therebetween, the distal end of said needle hub attachment assembly sized and configured for leak-free engagement with said needle hub, the needle hub attachment assembly comprising a chamber communicating with said needle assembly for receiving said body fluid, the needle hub attachment assembly comprising an elastomeric valve; and an assembly comprising a hemostatic segment, said assembly having a proximal end, a distal end, and a passageway extending therebetween, said hemostatic segment comprising a valve positioned in said passageway at said proximal end of said assembly and having an opening permitting passage of a wire guide therethrough, said distal end sized and configured for leak-free engagement with the proximal end of said needle hub attachment assembly, said passageway aligned with said needle assembly passageway and said needle hub attachment assembly passageway to form a path for insertion of said wire guide into said body vessel, wherein the distal end of said assembly comprising a hemostatic segment tapers to an endhole having a diameter substantially the same as the diameter of the wire guide.
