Abstract

A hemostasis valve apparatus having a quick release apparatus that allows for the exchange of guidewires and other medical instruments into a patient's vasculature while controlling the flow of blood during the exchange. The quick release capability allows tools and instruments to be introduced and removed from the patient's body in a quick and efficient manner without requiring undue attention or manipulation. The quick release capability comprises a lever mechanism which selectively seals or unseals a lumen of the hemostasis valve apparatus. The hemostasis valve apparatus can include a supplemental securement valve assembly which provides a secondary mechanism to secure an instrument positioned in the hemostasis valve and/or control the flow of blood from during the procedure. According to yet another aspect, the quick release mechanism allows for access to the lumen of the hemostasis valve apparatus when the quick release mechanism is in both a released and secured position.
