• Angled with backward curl - ANSGrollman Pigtail
• Catheter with an inflatable balloon near it's tip
• Used to remove emboli & thrombi from cardiovascular system - ANSFogarty Catheter
• Specialized cardiac catheter with a curved steel inner needle that can puncture the intra atrial septum
• Used to catheterize the left ventricle when the aortic valve cannot be crossed in a retrograde approach - ANSBrockenbrough Transseptal Catheter
• Specialized catheter that provides temporary or emergency transvenous pacing with variety of catheters
• Proximal & red electrode is positive

3 Considerations for Wire selection: - ANS- Stiffness

• Flexibility
• Smoothness A thin, usually flexible wire that can be inserted into confined space to act as guide for insertion of bulkier instrument - ANSGuidewire Guidewire:
• Curve in distal tip
• Radius of 3, 6, or 15 mm
• Easily follows path of torturous vessel
• Most popularly used - ANSJ-Tipped Spring Guidewire:
• Regular core wire gradually diminished in diameter at distal tip
• Wire easier to control & greater flexibility
• 3 cm - 20 cm
• Minimized problem of guidewire flipping or jolting out of vessel entrance - ANSTapered Core Guidewire Guidewire:
• Rigid core is fixed at proximal end of wire

• Unattached at distal end - ANSFixed-Core Guidewire Guidewire:
• Rigid core not fixed at either end
• Core attached to handle at proximal end of wire - ANSMovable-Core Guidewire Guidewire:
• Straight wire only 300 cm length
• Used for cath exchange while tip remains in vessel
• Used in diagnostic caths & interventions - ANSExchange Guidewire Instrument facilitates passage & exchange of catheters through a closely fitted sheath - ANSIntroducer Sets Introducer Sets consists of: - ANS- Tapered Dilator
• Hemostatic Valve
• Side Port Tubing with Stopcock Left heart catheters are generally what size? - ANS100 - 110 cm Pacing catheter containing 1 wire, a negative electrode that comes in contact with myocardium - ANSUnipolar Catheter

Pacing catheter containing 2 wires with 2 electrodes: distal electrode is negative (black), proximal electrode (red) is positive - ANSBipolar Catheter Standard PVC thermodilution catheter with additional lumen for insertion of temporary pacemaker probe into right ventricle - ANSThermodilution Pacing Catheter Types of Guidewires: - ANS- Fixed-Core

• Movable-Core
• J-Tipped Spring
