Abstract: An introducer sheath assembly (10) having a sheath tube (12), a hub (16), a valve (30) and a valve-retaining cap (50) on the proximal end of the hub. The cap (50) is so secured to the hub (16) as to have a closed, locked position and also an open position permitting access to the interior of the hub and the valve (30) while the cap (50) remains secured to the hub (16).

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 device further includes a dilator disposed on and slideable along the elongated body of the needle and a medical article. 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 the needle hub is in the second position.

Abstract: An access device places a medical article within a body space of a patient. The device has a needle section that includes an elongated body and a needle hub. The device further includes a dilator portion that has a dilator and a dilator hub. The dilator is coaxially disposed and slideable over the elongated body of the needle section. The device further includes a sheath section that has a sheath and a sheath hub. The sheath is coaxially disposed and slideable over the dilator. The device further includes a first locking mechanism operably disposed between the needle hub and the dilator hub to inhibit at least unintentional axial movement between the needle section and the dilator portion and a second locking mechanism operably disposed between the dilator hub and the sheath hub to inhibit at least unintentional axial movement between the dilator portion and the sheath section.

Abstract: A tearaway sheath assembly (100) having a splittable sheath tube (102) a splittable hub (110), a split valve (150,250) and a split cap (180). The valve (150,250) has a slit (158,258) at least partially across the transverse distal section (154) such that transverse distal section may be displaced laterally during insertion through the slit (158,258), of a dilator (200) or a catheter. The valve (150,250) is formed in two separate halves (152A,152B;252) that are fused or adhered to each other to form a sealed weak bond (154) that is easily broken during splitting of the sheath; each valve half is mechanically affixed in a proximal valve-receiving recess (130) of the hub such as by anchor posts (136) extending through apertures (166A,166B) in ears (164A,164B) of each valve half. A two-part cap (180) is affixed to the hub proximal end (120) and traps the valve between itself and the hub.
