Abstract
The presently disclosed subject matter is directed to a vein introducer and/or cannulation needle. Specifically, the needle includes a straight section attached to a distal end of a housing, and a curved section that comprises sharp tip. The curved or arcuate section is shaped to facilitate vessel introduction and maneuverability. Thus, the curved shape of the needle allows a user to access an internal vessel (e.g., a subclavian vein) in a parallel manner. As a result, the vessel can be accessed more safely and with decreased pain. The disclosed needle can therefore be used to provide fluidic and/or instrument access to an internal body structure (e.g., a subclavian vein).
Claims15
A tubular needle comprising:
- a housing defined by a housing proximal end and a housing distal end, wherein the housing proximal end includes a connector;
- a straight section comprising a proximal end and a distal end, the proximal end of the straight section operably connected to the housing distal end;
- a curved section comprising a proximal end and a distal end, wherein the proximal end of the curved section is operably connected to the distal end of the straight section, and wherein the distal end of the curved section comprises a sharpened tip;
- wherein the curved section comprises a central angle of about 150 degrees to about 270 degrees, is configured as a segment of a circle, and forms a substantially C-shaped or U-shaped configuration.
