Abstract

The present invention provides an assembly for the preparation of a medical device having a porous coating comprising hydrogen peroxide. Particularly interesting medical devices are catheters (such as urinary catheters), endoscopes, laryngoscopes, tubes for feeding, tubes for drainage, guide wires, condoms, urisheaths, barrier coatings e.g. for gloves, stents and other implants, extra corporeal blood conduits, membranes e.g. for dialysis, blood filters, devices for circulatory assistance, dressings for wound care, and ostomy bags. The coating is in particular a hydrophilic coating formed from cross-linked polyvinylpyrrolidone. In one embodiment, the assembly holds a dry catheter element in one compartment of a package and an aqueous hydrogen peroxide solution in another compartment. The solution may also comprise stabilizers, e.g. chelators, and osmolality increasing agents. The catheter for insertion in the urethra is useful for the treatment, alleviation or prophylaxis of microbial infections such as urinary tract infections (UTI).

Description

field of invention

[0001] The present invention relates to components useful for providing a medical device having a coating of a porous polymer composition, e.g. a hydrophilic coating, on at least a portion of its surface, wherein the coating comprises a liquid, e.g. A liquid expansion medium comprising hydrogen peroxide.

[0002] The invention also relates to the medical device itself, in particular the expansion medium containing hydrogen peroxide, and the medical use of said components and medical devices. Background of the invention

[0003] In many medical applications, polymer compositions constitute at least a part of medical devices, such as hydrophilic coatings, hydrogels, stents, adhesives, etc., which can be used in close contact with the human body. Medical devices can also be used to introduce, cover, or fill body cavities. Examples of body cavities or openings may be naturally occurring cavities such as the urethra, mouth, ear, nose, eyes, rectum, or artific...
