摘要:
A hemostasis valve includes a single gland with multiple offset longitudinal slits that do no extend through the gland completely. The multiple slits from a complex pathway for the guide dilator/catheter and thus a better seal. The offset slits are joined by a lateral cut in the gland. When a guide wire or dilator/catheter in introduced into the introducer, the gland deforms sufficiently to allow the guide wire or other device to move through the first slits, the lateral cut and the second slits. This complex pathway or slit provides a larger sealing surface thereby creating a better seal. As a result, effective seals may be formed around relatively large, as compared to the inner diameter of an introducer sheath, catheters.
摘要(中):
止血阀包括具有多个偏移纵向狭缝的单个腺体,其不完全延伸穿过腺体。 来自导向扩张器/导管的复合路径的多个狭缝,因此更好的密封。 偏移狭缝通过腺体中的横向切口连接。 当引导线或扩张器/导管引入引导器时,腺体足够变形以允许导丝或其它装置移动穿过第一狭缝,横切和第二狭缝。 这个复杂的路径或狭缝提供了更大的密封面,从而形成更好的密封。 结果,与引导器套管的内径相比,导管可以相对较大地形成有效的密封。
