Vascular catheters catheters are categorized categorized as diagnostic diagnostic or Diagnostic catheter sizes range from 4F to 6F, and guide. Diagnostic catheters are further categorized zed into lengths from 50 to 125 cm, respectively. respectively. Many catheters selective and flush. Both diagnostic and guide catheters are braided, with a soft tip. have a variety of head shapes to choose from. The name of the shape is consistent among both types of catheters, although there are generally less guide catheter shapes to choose from.
The ability of the catheter to follow the guidewire through tortuous vessels and around corners without pulling the wire out of it intended location.
The description of how how a force applied applied by the operator at the hub of t he catheter relates to the forward movement of the tip (the leading edge) of the catheter catheter..
Guide catheters are generally 6F, 7F or 8F and range from 65 to 100 cm in length. Guide catheters have reinforced construction and a much stiffer shaft to provide back-up support for the advancemen advancementt of guidewires, balloons and stents.

Catheter head shape determines function. Catheter head shapes can be categorized as simple and complex. Simple curves have a single primary curve. Complex curves have a primary and secondary curve, curve, and sometimes more. Two types of complex curves curves include the reverse curve and the double curve. The flush catheter typically round to protect the vessel walls from the whipping effect during power-injected power-injected boluses of contrast.

Surface Coat Surface coatings can modify thrombogenicity, friction coefficient or antimicrobial properties.
Outer Layer o Polyurethane catheters are softer and more pliable and follow guidewires more easily, but have a higher coefficient of friction. o Nylon catheters, which are stiffer and tolerate higher flow rates, are useful for aortography and general arteriography. o Teflo Teflon n is the stiffest material material and is used mainly for dilators and sheaths.
Tip A rounded tip is considered considered to be less traumatic than square cut tubing or bevel ended tubing which is easier to insert.

Reinforcement Many catheters have single or double wire-braiding for extra torquability. Highly braided catheters, while having excellent torque control, tend to be “all or nothing” in their response. Left Internal Mammary 1

IP LENGTH – Increased length offers more stability in target vessel at the cost of maneuverability in the parent vessel. T IP PRIMARY CURVE – Choose the optimal curve by assessing the angle of the target vessel from its parent artery. SECONDARY CURVE – Choose the optimal curve by assessing the width of the parent vessel. T ERTIARY – Choose the optimal curve by assessing normal curvature of the parent vessel. ERTIARY CURVE – Choose C ATHETER LENGTH – oShorter length catheters (50 cm) are used for the contralateral iliac artery injections. oMid length catheters (65 cm) are used for the visceral vessel cannulation (renal, celiac, superior mesenteric). oLonger length catheters (100-125 cm) are used for the abdominal arch and its branches.
