## Abstract

The present disclosure includes and provides for methods of packaging medical devices that are to be treated with a fluorinated liquid to alter their surface properties, packaging systems for such medical devices, and methods of utilizing the packaging systems to treat the medical devices. The packaging systems permit effective storage and distribution of medical devices that upon contact with mammalian blood have limited thrombogenicity or are non-thrombogenic and/or are resistant to adhesion of blood cells or clots.

## Claims

### Claim 1

A medical device packaging system comprising:
(i) a base having a channel substantially conforming to the shape of a medical device, the channel having a volume;
(ii) a cover forming a substantially gas and liquid tight seal over the channel, wherein the cover can be peeled away from the base exposing all or part of the channel; and
(iii) a medical device disposed in the channel, the medical device comprising a fluoropolymer and/or perfluoropolymer component or coating on all or part of its surface;
wherein the medical device comprises a connector to the medical device that is also disposed in the channel;
wherein the medical device comprises a fluoropolymer and/or perfluoropolymer; and
wherein the medical device further comprises a fluorinated liquid which comprises or is one or more perfluorinated liquids.

### Claim 2 (depends on 1)

The packaging system of claim 1, wherein the base is made by additive manufacturing, casting, injection molding, stamping, or pressing.

### Claim 3 (depends on 1)

The packaging system of claim 1, wherein the base is made from polymeric material.

### Claim 4 (depends on 3)

The packaging system of claim 3, wherein the polymeric material is selected from the group consisting of: low density polyethylene, high density polyethylene, polypropylene, polyethylene terephthalate, polyvinyl chloride fluoropolymers, perfluoropolymers, and combinations thereof.

### Claim 5 (depends on 1)

The packaging system of claim 1, wherein the channel has a volume less than 300% of the volume of the medical device.

### Claim 6 (depends on 1)

The packaging system of claim 1, wherein the base has a substantially planar surface and one or more sides abutting the substantially planar surface; and

### Claim 20 (depends on 1)

A method for treating a medical device with a fluorinated liquid comprising obtaining a medical device packaging system according to claim 1 and introducing the fluorinated liquid into the channel, wherein the channel has a volume.
