They have 3 different varieties (Sim 1, 2 and 3). 4 French and 5 French sizes are available. Sim catheters can be used for transradial as well as transfemoral approaches. Possibility of engaging the left subclavian by the transradial route has made this an option for <a href=\"https:\/\/johnsonfrancis.org\/professional\/left-subclavian-angiogram-to-visualise-lima\/\">angiography of the left internal mammary artery (LIMA)<\/a> when coronary artery bypass is the option after a diagnostic coronary angiography. Sim catheters comes in handy when there is difficulty in engaging the left subclavian artery using the Tiger or Judkins right coronary catheter. LIMA angiography is often needed while evaluating post coronary artery bypass graft patients in whom patency of the LIMA graft has to be documented.<\/p>\n<p>Simmons 1 and 2 are the curves usually selected for transradial cerebral angiography. In a study, 92 out of 103 LIMA grafts could be cannulated selectively or semi-selectively using a modified Simmons catheter producing satisfactory image quality [3]. Modified Simmons catheter is prepared by bending the tip of the catheter (See reference 3 for images).<\/p>\n<p><span style=\"color: #0000ff;\">Inflating the blood pressure cuff on the left arm during non-selective injection<\/span> (into the left subclavian artery) produces better images of the LIMA.
