A multicenter randomized trial comparing a percutaneous collagen hemostasis device with conventional manual compression after diagnostic angiography and angioplasty.

Objectives: A new percutaneous collagen hemostasis device was compared with conventional compression techniques after diagnostic catheterization and angioplasty. Background. Peripheral vascular complications after diagnostic catheterization or more complex interventional procedures, as well as the discomfort of manual compression and prolonged bed rest, represent significant morbidity for invasive cardiac procedures.
