What are guide catheters?

Guiding catheters are generally stiffer to provide backup support for the balloon/stent catheter advancement into the coronary artery and therefore respond differently to manipulation than do diagnostic catheters. The guide catheter and side holes act as a “second stenosis” at the coronary ostium.

How do I choose a guiding catheter?

Performance of a guiding catheter can be assessed based on three factors: (1) easy and rapid engagement without specific manipulation, (2) strong backup force, and (3) safety not causing complications such as coronary or aortic dissection. An ideal guiding catheter should be easy to manipulate, supportive, and safe.

What Is A Judkins catheter?

Judkins coronary catheter a preformed J-shaped angiographic catheter used in coronary arteriography to cannulate and deliver contrast material to one of the coronary arteries via a percutaneous femoral route. left coronary catheter one designed for coronary arteriography of the left coronary artery.

What can a guide catheter be used for?

The guide catheter provides support for device advancement (stents, balloons, etc.). It is the conduit for device and wire transport, a vehicle for contrast injection and takes measurements. Guide catheters are available in a variety of shapes and sizes to fit a variety of patient anatomies.

Which is better Medtronic guideliner or telescope catheter?

Medtronic. Deliverability bench testing: Telescope™ GEC 6 F vs. GuideLiner™* V3 GEC 5.5 F/6 F vs. Guidezilla™* II GEC 6 F. Differences among the means are significant if p < 0.05. N = 8 for each GEC tested. 10 test cycles per GEC.

What kind of aspiration catheter does Medtronic use?

The Export Advance™ aspiration catheter delivers consistent, high-performing aspiration power when it matters most. The Export™ AP aspiration catheter with Full-Wall technology has a soft, forward-facing tip for particle capture.

What do you need to know about telescope guide extension catheters?

Pushability is a critical component of deliverability. You want a soft, flexible tip with responsiveness when you need it. After positioning a GEC, the ability to deliver stents, balloons, and other interventional devices through the catheter is critical.
