We have found that an angled tip with a 40-degree angle and a distal length of 1 to 3 mm
can be useful in subselecting intracranial vessels whose origins are otherwise difficult to …

Placement of a guiding catheter through a tortuous, narrowed, or intrinsically small vessel
may result in severe reduction or occlusion of blood flow. However, nonbraided guiding …

Balloon-tipped microcatheters allow flow-guided entry into small vessels and permit
selective angiography, selective drug infusion, temporary or permanent vessel occlusion …

We describe the use of an epidural catheter adapter to salvage a flow-directed microcatheter
in situ after fracture of the plastic catheter hub. This technique eliminates the need to remove …

A new plastic guide wire featuring a low-friction surface, high torque control and increased
pushability whilst still maintaining floppiness of the distal end was developed for the sake of …

Materials and Methods Over the last 18 months, 85 procedures were performed on 58
patients for a variety of pathologic conditions (Table 1). Ages ranged from 8 months to 74 …

The purpose of this study was to describe a balloon-assisted double-lumen microcatheter
technique to perform a controlled and tight coil packing of a vascular segment for vessel …

We report a case in which navigation of the micro catheter (Headway 027) with the
conventional single microwire technique became impossible because of the difficult …

A new catheter suitable for selective angiography, embolization, and controlled infusion of
chemotherapeutic agents is described. The catheter is made from a composite construction …

A technique is described for occlusion of the middle cerebral artery in the baboon by an
intravascular approach. A torque catheter is introduced under fluroscopic control into the …
