Claim:
1. An intravascular assembly for catheterization comprising: a. an introducer needle comprising a connection hub and a needle member, wherein the needle member has a lumen, a distal end provided with a blood entry aperture, and a proximal end, and wherein the connection hub defines an inner chamber adapted to receive blood exiting from the proximal end of the needle member; b. a light guide having a distal end and a proximal end and extending along the lumen of the needle member, wherein the distal end of the light guide is arranged inside the lumen of the needle member; c. an adapter secured to the light guide, wherein the light guide is arranged to extend through the adapter; and d. at least one light source, wherein the adapter is provided with an interface for the at least one light source, wherein the adapter is connected to the connection hub of the introducer needle, wherein the adapter is adapted to form a leak-proof barrier between blood within the inner chamber of the connection hub and the at least one light source, wherein the proximal end of the light guide is optically coupled to the at least one light source such that light emitted by the at least one light source enters the light guide and is emitted by the distal end of the needle member, and wherein the light emitted from the distal end of the needle member has a total light intensity, and wherein at least 70% of the light emitted from the distal end of the needle member has a wavelength between 510 nm and 610 nm.
