DESCRIPTION (provided by applicant): This is a proposal to investigate a novel dilation device that does not contain a folded balloon element. Dilation devices are widely used in the medical profession, usually as a component part of a catheter. Such catheters are usually referred to as balloon catheters. Balloon catheters are constructed by folding a deflated balloon around a catheter shaft. Our new device eliminates the folded balloon wrapped about a catheter. The device is suitable for use as the expansive element in angioplasty and other catheters. The device consists of a thin wall segment in a catheter whose outer diameter matches the outer diameter of the catheter. The thin wall segment expands upon the application of pressure to the interior of the catheter. Due to its low profile, it has the potential to reduce the size of currently available balloon catheters thereby extended the applicability of angioplasty to situations currently reserved for by-pass surgery. PROPOSED COMMERCIAL APPLICATION: Coronary angioplasty, neurological angioplasty, periferal angioplasty, stent delivery system, dilation of non arterial lumens such as biliary or kidney related.

描述（由申请人提供）：这是一份研究一种新的 不包含折叠球囊元件的扩张装置。扩张 医疗器械广泛用于医疗行业，通常作为组成部分 一个导管。这种导管通常被称为球囊导管。 球囊导管通过将放气的球囊折叠在球囊周围来构造， 导管管身。我们的新设备消除了折叠的气球包裹在一个 导尿管该装置适合用作膨胀元件， 血管成形术和其他导管。该装置由薄壁段组成， 导管，其外径与所述导管的外径匹配。的 薄壁段在压力施加到内部时膨胀， 导管。由于其低姿态，它有可能减少大小 因此，扩展了现有球囊导管的适用性， 血管成形术的情况下，目前保留旁路手术。 拟定商业应用： 冠状动脉血管成形术、神经血管成形术、外周血管成形术、支架输送系统， 非动脉管腔扩张，如胆道或肾脏相关。
