一種新型診斷性導(dǎo)管具有親水涂層，能夠使得醫(yī)生更好的控制復(fù)雜的、操作難度很高的導(dǎo)管插入手術(shù)。

Tempo Aqua導(dǎo)管能夠在選擇性導(dǎo)管插管術(shù)、頸動脈血管造影術(shù)中使用，以及其它一些正在出現(xiàn)的檢查諸如子宮纖維瘤栓塞以及subintimal angioplasty。該導(dǎo)管具有獨特的、三層尖端結(jié)構(gòu)，在其兩層尼龍層之間有不透輻射的鎢尖端物質(zhì)。這種設(shè)計有助于把凝血和生物兼容性難題降低到最小，同時保證尖端的完整性和強度。這種導(dǎo)管具有不同的尺寸、長度和形狀。

Forsyth醫(yī)療中心(Winston-Salem, NC, USA)血管外科醫(yī)生Stephen J. Motew醫(yī)生指出：“Tempo Aqua具有優(yōu)越的可跟蹤性以及穿越病變處的能力，這就使得較為困難的動脈病變治療變得容易。Tempo Aqua導(dǎo)管由于具有親水性和可扭轉(zhuǎn)能力，所有能夠進行復(fù)雜的全動脈閉塞的治療。”

這種新型導(dǎo)管是由Cordis公司研制開發(fā)的，該公司屬于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.
