Embodiment Construction

[0029] It is to be understood that the subject matter described herein is not limited to particular embodiments described, as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not restrictive, as the scope of the inventive subject matter is to be limited only by the appended claims. Where a range of values ​​is provided, it is understood that each intervening value between the upper and lower value of that range is encompassed as well as any other stated or intervening value within the stated range. within the disclosed subject matter.

[0030] Ⅰ. System Overview

[0031] Systems constructed in accordance with the present invention allow for sequential (eg, intermittent and repeated) expansion and deflation of an expandable member such as a balloon. In some embodiments, sequential inflation and deflation of the balloon is achieved by single-touch actuation. The term "o...

Abstract

A system including a catheter and an expandable member. The catheter includes an independent inflation lumen and an separate independent deflation lumen capable of sequential inflation and deflation of an expandable member in rapid succession, such as less than five seconds.

Description

technical field [0001] The present invention relates to catheter systems. More specifically, the present invention relates to catheters having an inflation lumen and a separate deflation lumen to allow rapid and sequential inflation and deflation of an expandable member, such as a balloon, which is particularly useful for reducing the occurrence of reperfusion injury. Background technique [0002] When a patient experiences an ischemic event in the coronary vasculature, peripheral vasculature, or cerebral vasculature, the blood supply to tissues and organs distal to the blockage or blockage is significantly reduced. The resulting hypoxia increases the risk of tissue and organ necrosis. In general, patients experiencing an ischemic event are treated with minimally invasive catheterization, eg, percutaneous transluminal coronary angioplasty (PCTA) if an obstruction occurs in the coronary vasculature. PCTA is used to dilate ischemic blockages and restore blood supply to tiss...
