Abstract
An access device for placing a medical article within a body space includes a needle, a dilator, and a sheath. The dilator can be coaxially and slideably disposed about the needle, and the sheath can be coaxially and slideably disposed about the dilator. The access device can further include a inner member coaxially disposed between the needle and dilator. The needle can include a fenestration in fluid communication with a space between the needle and inner member. When the needle punctures a blood vessel, the fenestration allows blood to flow into the space between the needle and inner member to provide a visual indicator to a physician or healthcare professional that the needle is in a vessel.
