  "abstract": "A system for controlling a hemostasis valve includes a hemostasis valve having a body portion having a proximal end, a distal end and a lumen extending between the proximal end and the distal end. The hemostasis value further includes at least one valve positioned in the proximal end of the body portion and an engagement member operatively coupled to the at least one valve. The system further includes a first drive member coupled to the engagement member and a controller coupled to the first drive member. The controller is configured to control the first drive member to impart movement to the engagement member to open and close the at least one valve.",
  "claims": [
    "1. A system for controlling a hemostasis valve comprising: a hemostasis valve comprising: a body portion having a proximal end, a distal end and a lumen extending between the proximal end and the distal end; at least one valve positioned in the proximal end of the body portion; and an engagement member operatively coupled to the at least one valve; the hemostasis valve being moved from a raised position to an-in use position, a first drive member removably coupled to the engagement member as the hemostasis valve is moved from the raised position to the in-use position; a controller coupled to the first drive member, the controller configured to control the first drive member to impart movement to the engagement member to open and close the at least one valve; and a second drive member coupled to the engagement member and the controller, the controller configured to control the second drive member to impart movement to the engagement member to open and close the at least one valve; and wherein the first drive member imparts rotational movement to the engagement member; and wherein the second drive member imparts linear movement to the engagement member.",
    "2. The system according to claim 1, wherein the controller is configured to incrementally adjust an amount the at least one valve is opened or closed.",
    "3. The system according to claim 1, wherein the at least one valve is a Tuohy-Borst valve.",
    "4. The system according to claim 1, wherein the controller rotates the engagement member about a longitudinal axis of the hemostasis valve to increase or decrease a size of an opening of the at least one valve.",
    "5. The system according to claim 1, wherein the at least one valve is a bleedback valve.",
    "6. The system according to claim 5, wherein the controller translates the engagement member along a longitudinal axis of the hemostasis valve to open and close the at least one valve.",
    "7. The system according to claim 1, wherein the at least one valve includes a bleedback valve and a Tuohy-Borst valve."

  "description_excerpt": "The present application relates generally to the field of catheter systems for performing diagnostic and/or percutaneous coronary intervention procedures. The present application relates specifically to a guide catheter control in a robotic catheter system.\n\nVascular disease, and in particular cardiovascular disease, may be treated in a variety of ways. Surgery, such as cardiac bypass surgery, is one method for treating cardiovascular disease. However, under certain circumstances, vascular disease may be treated with a catheter based intervention procedure, such as angioplasty. Catheter based intervention procedures are generally considered less invasive than surgery.\n\nDuring one type of intervention procedure, a guide catheter is inserted into a patient's femoral artery through an introducer and positioned proximate the coronary ostium of a patient's heart. A guide wire is inserted into the guide catheter typically through a hemostasis valve and maneuvered through the patient's arterial system until the guide wire reaches the site of the lesion. A working catheter is then moved along the guide wire until the working catheter such as a balloon and stent are positioned proximate the lesion to open a blockage to allow for an increased flow of blood proximate the lesion. In addition to cardiovascular disease, other diseases may be treated with catheterization procedures.",
