Its distal tip, straight or J-shaped, is usually radio-opaque which aids its visibility while it is being handled, in addition to its use for estimating the length of the lesion. The basic composition of guidewires is well established: central core, distal tip, covering and coating1. One of the fundamental characteristics of the tip is its weight or load, tip load, as we will discuss shortly, which is very important for the intended design and use of the CAG. For the study of the differential characteristics of the CAGs we will classify them into four groups: for standard use, flexible, high support and for chronic occlusions, which have a high tip load, as we will see.

Intracoronary pressure and flow velocity with sensor-tip guidewires: a new methodologic approach for assessment of coronary hemodynamics before and after coronary interventions.
The use of miniaturized pressure and velocity sensors mounted on angioplasty guidewires allows the simultaneous measurement of coronary blood flow velocity and transstenotic pressure gradient, 2 parameters that, combined, should perfectly characterize stenosis hemodynamics. The aim of this article is assessment of the changes in coronary blood flow velocity observed with a Doppler-tipped angiop...

METHODS In 50 patients with oneand two-vessel coronary artery disease (CAD) undergoing percutaneous transluminal coronary angioplasty (PTCA), collateral flow index (CFI, no unit) changes and vascular resistance index (R, cm/mm Hg) changes of the collateral (Rcoll) and the distal collateral receiving (R4) vessel in response to adenosine (140 mg/min/kg IV) were measured by intracoronary (i.c.)

متن کاملFulfilling the promise of percutaneous angioplasty.
It is ironic that in 1964, Dotters’ initial application of percutaneous transluminal angioplasty (PTA) targeted femoral-popliteal stenoses. Now, nearly 4 decades later, although angioplasty has gained wide acceptance as a firstline treatment for diseased coronary, iliac, and renal arteries, its role in femoral-popliteal vessels remains controversial and poorly defined. The initial PTA procedure...

angioplasty by Gruentzig in 1977, this revascularization technique has been applied to an increasing number of patients and in different clinical scenarios. However, chronic total occlusions are still considered to be a challenge for the interventional cardiologist. It has been estimated that approximately 10% of all angioplasty procedures are currently undertaken for chronic total occlusions. ...

OBJECTIVES We aimed to evaluate the safety and feasibility of a robotic angioplasty system in delivery and manipulation of coronary guidewires, balloons, and stents in patients undergoing elective percutaneous coronary intervention (PCI). BACKGROUND A remote-control, robotic-assisted angioplasty system is under development to address some of the procedural challenges and occupational hazards ...
