Abstract: An access device (20) places a medical article within a body space of a patient. The device has a needle (22) that includes an elongated body (32) and a needle hub (34). The device further includes a dilator (24) disposed on and slideable along the elongated body of the needle and a medical article (26). The medical article is disposed on and slideable along the dilator. A track extends in a proximal direction from the dilator. The needle hub slides along at least a portion of the track between a first position and a second position. The device further includes a locking mechanism operably disposed between the track and the needle hub so as to inhibit further axial movement of the needle in the proximal direction when ibe needle hub is in the second position.

Abstract: An access device (20) places a medical article within a body space of a patient. The device has a needle (22) that includes an elongated body (32), a side fenestration (56) on the elongated body, and a needle hub (34). The device further includes a dilator (24) disposed on and slideable along the elongated body of the needle and a medical article (26). The medical article is disposed on and slideable along the dilator. The dilator and the needle form one or more spaces (150) in communication with the side fenestration (56). At least portions of the dilator and the medical article are configured so as to allow visual determination of the presence of a bodily fluid within the space. The outer surface of the needle and the inner surface of the dilator can include a surfactant. Further, at least one of the needle and dilator can further comprise a vent in communication with the space that allows for the escape of air from the space and inhibits the escape of the bodily fluid from the space.

Abstract: An access device places a medical article within a body space of a patient. The device has a needle that includes a needle body and hub. The device further includes a dilator coaxially disposed and slideable over the needle body and a medical article. A viewing space is disposed between the dilator and the medical article with at least one passageway or conduit connecting the viewing space with the interior bore of the needle body. The passageway is defined at least in part by openings through the sides of the needle and dilator. At least a portion of the conduit or passageway can be defined by one or more grooves between the needle and dilator. The device can further include a guidewire and an interlock between the guidewire and the needle and/or dilator. The device can further include one or more stops disposed between the guidewire and the needle and/or dilator to limit the extent to which the guidewire can be moved (e.g., advanced) relative to the needle or inhibit such relative movement (e.g., backwards movement).

Abstract: In some embodiments of the invention, an access device can be provided. Advantageously, the access device can enhance the detection of the device's access into a desired body space. For example, the access device may have portions with enhanced visibility to a naked human eye, or an imaging device such as a medical imaging device. Where an imaging device is used, the imaging device can image the access device in a space that usually would not be visible to an operator, such as within a medical patient's body. Where the access device is directly viewed by a human eye, the access device can provide some form of feedback that allows an operator to more quickly discern if the access device has entered a desired space. For example, if the access device is to enter a blood-filled body space, the access device can allow blood to flow up and into the device, and the device can make the blood's presence more immediately apparent. One method of making the blood's (or another fluid) presence more immediately apparent is using a portion with contrasting optical properties.

Abstract: An access device places a medical article within a body space of a patient. The device has a needle that includes an elongated body and a needle hub. The medical article is disposed over and slideable over the needle. A flash space is provided anywhere between the needle and the outer surface of the medical article. The flash space communicates with a bore of the needle, as well as a variable volume chamber. The variable volume chamber can then draw fluid from the flash space into the chamber.

Abstract: A sheath can include a sheath body and a sheath hub. The sheath body can have a generally flexible tubular structure, a proximal end, and a distal end. The sheath body can further define a longitudinal axis. The sheath hub can attach to the proximal end of the sheath body and define a longitudinal axis generally aligned with the axis of the sheath body. The sheath body and sheath hub can also form a central cavity along their respective axes. The sheath hub can include two plates: a flexible plate and a rigid plate. The rigid plate can have a relief generally centered on the sheath body's axis. Advantageously, the flexible plate and rigid plate can overlap to substantially seal the central cavity.
