发明名称 Introducer for an Endoluminal Procedure
摘要 The invention relates to an introducer for an endoluminal procedure. The inventive introducer comprises: a guide tube which can be inserted into the human body and which defines an internal guide conduit for an element that is to be introduced, and a hemostatic valve which is formed at one end of the guide tube and which, in the open configuration, defines a passage with a large cross-section in the extension of the guide conduit, and, in the closed configuration, defines a passage with a reduced or zero cross-section. The aforementioned hemostatic valve comprises: a rigid annular support which is connected to the guide tube and which extends axially from same; and an inner annular pouch which is formed axially inside the annular support, which is defined, along the surface thereof facing the axis, by an elastically-deformable flexible membrane, and which is filled with a filling liquid.
