Access device with valve
First Claim
1. A splittable sheath comprising:
- a splittable sheath body comprising a generally flexible tubular structure, a proximal end, and a distal end, the sheath body defining a longitudinal axis and being splittable into two halves along a pre-determined line generally parallel to the longitudinal axis; and
a sheath hub extending from the proximal end of the sheath body defining a longitudinal axis generally aligned with the axis of the sheath body, the sheath body and sheath hub forming a central cavity along their respective axes, the sheath hub additionally comprising;
a flexible body; and
a rigid body, the rigid body comprising a relief generally centered on the longitudinal axis,wherein the flexible body and rigid body can overlap to substantially seal the central cavity, and allow a medical article to pass through the cavity without holes or slits in the flexible body.

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.

12. An access device comprising:
-
a needle; a dilator coaxially mounted on the needle, the dilator comprising a dilator shaft and a dilator hub; a splittable sheath coaxially mounted on the dilator, the sheath comprising; a sheath body comprising a proximal end, and a distal end; and a sheath hub extending from the proximal end of the sheath body at a distal end of the sheath hub, and reversibly attached to the dilator hub at a proximal end of the sheath hub, the sheath body and sheath hub forming a central cavity, the sheath hub comprising a flexible body and a rigid body, wherein the flexible body and rigid body allow the needle and dilator to pass through the cavity without holes or slits in the flexible body, and wherein the flexible body and rigid body can overlap to substantially seal the central cavity when the needle and dilator are removed from the cavity. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A packaging comprising:
-
a needle; a dilator; a splittable sheath comprising; a sheath body comprising a proximal end, and a distal end; and a sheath hub extending from the proximal end of the sheath body at a distal end of the sheath hub, the sheath hub comprising a substantially solid flexible body, a rigid body, and an attachment portion at a proximal end configured to attach to the attachment portion on the dilator hub, wherein the sheath body and sheath hub form a central cavity that receives the dilator and needle without passing through holes or slits in the flexible body, and the flexible body and rigid body can overlap to substantially seal the central cavity when the dilator and needle are removed; and wherein the needle, dilator, and sheath are prepackaged together. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
