Patent ID: 8781586

Claim:
A method of providing temporary cardioprotective pacing comprising: providing a hemostasis valve comprising: a valve body including a proximal port and a distal port, the valve body defining a lumen extending between the proximal and distal ports; a valve disposed in the lumen, the valve including a resilient material defining an opening, the resilient material being configured to deform and form a seal around a medical device that is extending through the opening; and an adjustable electrical contact disposed in the lumen and having an electrically conductive surface, the adjustable electrical contact having an expanded configuration and a constricted configuration; disposing a therapeutic system through the opening in the valve and the adjustable electrical contact, the therapeutic system comprising one or more distal electrodes and a conductive element electrically coupled to the one or more electrodes and extending along a portion of the therapeutic system, the valve portion of the hemostasis valve sized and configured to seal around a portion of the therapeutic system; disposing a distal portion of the therapeutic system in a cardiac artery; moving the adjustable electrical contact from an expanded configuration to a constricted configuration; piercing an outer layer of the therapeutic system; and making electrical contact with the conductive element; providing cardioprotective pacing signals through the hemostasis valve to the electrode.
