摘要：
A tearaway sheath assembly (100) having a splittable sheath tube (102) a splittablehub (110), a split valve (150, 250) and a split cap (180). The valve (150, 250) hasa slit (158, 258) at least partially across the transverse distal section (154)such that transverse distal section may be displaced laterally during insertionthrough 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 toeach other to form a sealed weak bond (154) that is easily broken during splittingof the sheath； each valve half is mechanically affixed in a proximal valve-receivingrecess (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 affixedto the hub proximal end (120) and traps the valve between itself and the hub. Pairsof opposed gaps (184, 122) of the cap (180) and the hub (110) are aligned with linesof weakness or seams (106) of the sheath tube (102) and the weak bond (154) of thevalve, facilitating splitting of the assembly (100) when desired by the practitionerto peel it away from the inserted catheter.
