1. A medical device, comprising:
- a tubular sheath having two spaced apart wire stabilization guides, the stabilization guides each comprising elongated members having at least a portion thereof extending from an end of the sheath;
a retention device formed on the portion of each of the stabilization guides extending from the end of the sheath, the retention device configured to selectively expand outwardly from the stabilization guide in at least one direction;
a wire moveably disposed within at least a portion of one of the stabilizations guides, the wire being coupled to the stabilization guide, wherein movement of the wire in a first direction causes outward expansion of the retention device; and
a guide rod sized to fit within the tubular sheath and having two slots formed along its length, at least one slot releasably holding a respective one of said wire stabilization guides.

Abstract
An introducer having a sheath, a guide rod, and at least two wire stabilization guides being elongated members, at least a portion of which extend from an end of the sheath. The portions of the wire stabilization guides include a retention device formed on the portion of the wire stabilization guides that extend from the end of the sheath. The retention device is adapted to selectively expand outwardly, stabilizing the sheath relative to a wound site. The guide rod may be provided with one or more blood marking lumen, having a distal port, for identifying the depth of insertion into an artery or vein based on the presence or absence of pressurized blood in the lumen.

11. A medical device, comprising:
-
a tubular sheath having two spaced apart wire stabilization guides, the stabilization guides each comprising elongated members having at least a portion thereof extending from an end of the sheath;
the sheath further comprising a plurality of tear seams formed along at least a portion of the length thereof and wherein when the sheath is approximated to a wound site and a radial force is applied to the distal end of the sheath in a direction generally perpendicular to the central axis of the sheath, the tear seams are caused to tear increasing the diameter of the sheath,a retention device formed on the portion of each of the stabilization guides extending from the end of the sheath, the retention device configured to selectively expand outwardly from the stabilization guide in at least one direction; and a guide rod sized to fit within the tubular sheath and having two slots formed along its length, at least one slot releasably holding a respective one of said wire stabilization guides.
