Problems solved by technology

However, the bioactive coating may be scraped off as the balloon is inserted through the introducer, especially if the balloon must be inserted through another device such as a hemostatic valve (eg, in the introducer) or disappear
For example, the device or hemostatic valve may have edges, and as the balloon is inserted through the device or hemostatic valve, forces may be concentrated at the edges, which may cause the bioactive coating to be scraped off
Also, the coating may be more prone to movement if exposed to fluids prior to insertion

Abstract

A peelable protective sheath and related assemblies / systems and methods are disclosed. The protective sheath may be used on a balloon catheter to protect the balloon and any coating thereon. The protective sheath may be peelable to make removal of the protective sheath easier. The peelable protective sheath may be inserted into a hemostatic valve and introducer while still disposed over the balloon of a balloon catheter to protect the balloon and any bioactive coating thereon from damage during insertion. The peelable protective sheath may be peeled from a proximal end to initiate removal. Alternatively, the peelable protective sheath may be peeled from a distal end of the peelable protective sheath as the balloon catheter is inserted through a hemostatic valve and introducer.

Description

technical field [0001] This application claims the benefit of priority from US Provisional Application No. 61 / 819,433, filed May 3, 2013, which is incorporated by reference in its entirety. Background technique [0002] Angioplasty is used to treat blockages or narrowing of blood vessels, such as arteries. The blockage may be caused by a buildup of cholesterol on the walls of blood vessels or by the formation of a clot. In angioplasty, dilating balloon catheters are often used to dilate blood vessels and open blocked areas. A balloon catheter may be inserted into a patient's blood vessel using an introducer. The balloon catheter may be inserted through the introducer and advanced through the blood vessel until the distal end of the balloon catheter is at a desired location within the vasculature, such as the site of a blockage or narrowing of the blood vessel. A guide wire can be introduced and used to guide the balloon catheter to the desired location. The balloon cathe...
