一種新型超聲波血管內(nèi)系統(tǒng)被設(shè)計(jì)用于治療血栓合成透析移植（thrombosed synthetic dialysis access grafts）。這種系統(tǒng)已經(jīng)獲得了美國食品藥品管理局的許可。

Resolution血管內(nèi)系統(tǒng)是由OmniSonics醫(yī)療技術(shù)公司(Wilmington, MA, USA)制造的，是一種便攜式系統(tǒng)，由兩種主要成分組成，發(fā)生器和Resolution系統(tǒng)工具何。該工具盒有貼附導(dǎo)線的手工配件和附屬的沖洗導(dǎo)管。這種手工配件將來自發(fā)生器的電子信號(hào)轉(zhuǎn)換為低能量的超聲能量，在整個(gè)長(zhǎng)度的小直徑治療導(dǎo)線內(nèi)360o發(fā)射，產(chǎn)生氣穴流體作用，從而破碎血栓中的纖維基質(zhì)，而且不會(huì)破壞周圍結(jié)構(gòu)。

該設(shè)備正在接受治療外周血管(深靜脈血栓、外周四肢缺血和導(dǎo)管清除)堵塞、神經(jīng)血管和冠狀動(dòng)脈疾病的評(píng)估。

Treatment for Thrombosed Dialysis Grafts
 
A new ultrasonic endovascular system is designed for use in the treatment of thrombosed synthetic dialysis access grafts. The system has been cleared by the U.S. Food and Drug Administration (FDA).

The Resolution endovascular system, made by OmniSonics Medical Technologies (Wilmington, MA, USA), is a portable system that consists of two primary components, the generator and the Resolution system kit. The kit consists of a hand-piece with an attached wire and accessory irrigation tubing. This hand-piece converts the electronic signal from the generator to low-power ultrasonic energy transmitted 360o along the entire length of a small-diameter therapeutic wire, generating a cavitational streaming effect that breaks the fibrin matrix found in the thrombus without damaging surrounding structures.

The device is currently being evaluated for use in the treatment of peripheral occlusive conditions (deep vein thrombosis, peripheral limb ischemia, and catheter clearance), as well as neurovascular and coronary applications.
