Cordis研制出由亲水物质包被的诊断性导管

一种新型诊断性导管具有亲水涂层，能够使得医生更好的控制复杂的、操作难度很高的导管插入手术。

Tempo Aqua导管能够在选择性导管插管术、颈动脉血管造影术中使用，以及其它一些正在出现的检查诸如子宫纤维瘤栓塞以及subintimal angioplasty。该导管具有独特的、三层尖端结构，在其两层尼龙层之间有不透辐射的钨尖端物质。这种设计有助于把凝血和生物兼容性难题降低到最小，同时保证尖端的完整性和强度。这种导管具有不同的尺寸、长度和形状。

Forsyth医疗中心(Winston-Salem, NC, USA)血管外科医生Stephen J. Motew医生指出：“Tempo Aqua具有优越的可跟踪性以及穿越病变处的能力，这就使得较为困难的动脉病变治疗变得容易。Tempo Aqua导管由于具有亲水性和可扭转能力，所有能够进行复杂的全动脉闭塞的治疗。”

这种新型导管是由Cordis公司研制开发的，该公司属于Johnson & Johnson公司。

Hydrophilic-Coated Diagnostic Catheter
 
A new diagnostic catheter has a hydrophilic coating designed to provide doctors with better handling during complex, difficult-to-maneuver catheterization procedures.

The Tempo Aqua catheter can be used in selective catheterization, carotid angiography, and in emerging procedures such as uterine fibroid embolization and subintimal angioplasty. The catheter has a unique, three-layer tip construction in which the radiopaque tungsten tip material is embedded between two nylon layers. This design helps to minimize the potential for clotting and biocompatibility problems while maintaining the integrity and strength of the tip. The catheter is available in a variety of sizes, lengths, and shapes.

“Tempo Aqua provides superior trackability and lesion-crossing characteristics which facilitate treatment of difficult arterial lesions,” stated Stephen J. Motew, M.D., FACS, a vascular surgeon at Forsyth Medical Center (Winston-Salem, NC, USA). “The Tempo Aqua catheter has allowed treatment of complex total arterial occlusions due to its hydrophilic and torqueability qualities.”

The new catheter was developed by Cordis Endovascular (Warren, NJ, USA), a Johnson & Johnson company.
