DETAILED DESCRIPTION

Prevention of hospital acquired infections (HAI) is a focus of certain hospital resources. HAI results in morbidities and mortality to hospitalized patients that significantly impact the lives of patients and increase the cost of healthcare. Types of HAIs include pneumonia, gastrointestinal illness, urinary tract infections, blood stream infections, and surgical site infections.

Decontamination of surgical rooms has been found to be an effective method of reducing surgical site infections. Surgery rooms with associated equipment and supplies are decontaminated using technologies such as Vaporized Hydrogen Peroxide (VHP), formaldehyde gas, and chlorine dioxide gas. VHP is pumped into a surgical room and allowed to dwell for a period of time. During the dwell time the VHP vapor, in a ‘wet’ process, reaches dew point and condensates on exposed surfaces of floors, walls, equipment and supplies. In a ‘dry’ process (VHP vapor concentration is below the dew point) the VHP does not condense on surfaces but does make contact with the surfaces. VHP oxidizes the cell wall of bio-contaminants, including drug resistant microbes such as Methicillin-resistant Staphylococcus aureus (MRSA) and Vancomycin-resistant Enterococcus (VRE). Following the dwell time, VHP is evacuated from the room leaving a disinfected room with a reduced risk of exposing a patient to any virulent bio-contaminants.

VHP is an effective tool to decontaminate or disinfect a surgical room. However, exposure to VHP may cause degradation of polymer based medical devices that may be stored in the surgical room. These medical devices may be diagnostic or therapeutic vascular catheters packaged in porous materials. The VHP may penetrate the porous material and interact with the surface of the medical device. Hydrogen peroxide is a strong oxidizing agent. The hydrogen peroxide may cause degradation of the polymer of the catheter from the outside surface. Repeated exposure to VHP may result in a catheter material that is brittle and weak. Such catheters may fracture or catheter tips may break off in a patient when the catheter is used for a procedure. In some such instances, a portion of the catheter or tip may need to be retrieved from the vasculature of a patient.

As further detailed below, a packaging component may be configured to provide a diffusion inhibitor member to reduce exposure of a portion of a polymeric medical device to a decontaminating vapor or gas. Some packaging components and methods may be configured to reduce or prevent polymer component degradation when exposed to whole-room disinfecting techniques. Some such techniques may include whole-room disinfection with VHP, formaldehyde gas, chlorine dioxide gas, or any other gas or vaporized agent suitable to perform whole-room decontamination.

Common elements of the illustrated embodiments may be designated with similar reference numerals. Accordingly, the relevant descriptions of such features apply equally to the features and related components among all the drawings. Any suitable combination of the features, and variations of the same, described with components illustrated in FIG. 1, can be employed with the components of FIG. 2, and vice versa. This pattern of disclosure applies equally to further embodiments depicted in subsequent figures and described hereinafter. It should be understood that the figures presented are not meant to be illustrative of actual views of any particular portion of the actual structure or method, but are merely idealized representations employed to more clearly and fully depict the present invention defined by the claims below.

FIGS. 1-3 depict various views of individual components of a packaging system 100. FIG. 1 depicts a top view of the packaging system 100. Section line 2 of FIG. 1 indicates the line at which the cross-section depicted in FIG. 2 is taken. The packaging system 100 comprises a primary package 120, a support member 108, and a diffusion inhibitor member 106.

In some embodiments, the packaging system 100 is configured to contain a medical device 110, such as a vascular catheter. The medical device 110 comprises an elongate shaft 114, a connector 115 coupled to the proximal end of the elongate shaft 114, and a catheter tip 113 coupled to a distal end of the elongate shaft 114. The components of the medical device 110 may be formed from any suitable polymer or combination of polymers, such as polyethers, polyesters, nylon, polyether block amide, PEBAX®, polyurethane, etc. The elongate shaft 114 may comprise a stainless steel metal braid configured to increase physical characteristics of the elongate shaft 114, such as burst strength, kink resistance, rotatability, etc. A length of the elongate shaft 114 may range from 20 cm to 150 cm, including 30 cm to 125 cm. A diameter of the elongate shaft 114 may range from two French to eight French, including four French to five French. Other sizes and configurations of medical devices and catheters are within the scope of this disclosure.

The catheter tip 113 may be formed of a material or otherwise configured such that the catheter tip 113 is softer and/or more flexible than the elongate shaft 114. In some embodiments, the catheter tip 113 may be configured to minimize trauma when contacting a patient's vasculature and may not comprise a braid. The catheter tip 113 may be tapered at a distal end to facilitate passage of the medical device 110 through the vasculature of the patient.

The catheter tip 113 may also comprise a filler to increase radiopacity of the catheter tip 113. The increased radiopacity may allow the catheter tip 113 to be more easily identified within the vasculature of the patient using X-ray or fluoroscopy. The catheter tip 113 may be loaded with up to 80% by weight of any suitable radiopacifier filler, such as tungsten, tungsten carbide, barium sulfate, bismuth trioxide, bismuth subcarbonate, etc. Other fillers, such as color pigments, colarants, stabilizers, UV inhibitors, etc. may be incorporated into the material of the catheter tip 113. In some embodiments, the elongate shaft 114 and the catheter tip 113 may be coated with a hydrophilic coating configured to facilitate passage of the medical device 110 through the patient's vasculature. In some embodiments, the catheter tip 113 is coupled to the elongate shaft 114 utilizing heat and pressure. The elongate shaft 114 and the catheter tip 113 may be placed over a mandrel. The elongate shaft 114, catheter tip 113 and mandrel may then be inserted into a die that is heated by induction energy, such as radiofrequency energy. Application of a longitudinal force to the elongate shaft 114 and the catheter tip 113 as the materials of the elongate shaft 114 and the catheter tip 113 soften and melt may be utilized to bond the components. Furthermore, during this heating and application of force, a weld line 121 between the distal end of the elongate shaft 114 and a proximal end of the catheter tip 113 may be formed and the tapered shape of the distal end of the catheter tip 113 may be formed. The die is then cooled and the coupled elongate shaft 114 and catheter tip 113 are removed from the die. In other embodiments, other suitable techniques to couple the elongate shaft 114 and catheter tip 113 together may be used, such as gluing, over molding, laser welding, solvent bonding, etc. The catheter tip 113 may be formed as a straight extension of the elongate shaft 114. In other embodiments, the catheter tip 113 may be formed in any suitable two dimensional or three dimensional shape suitable to accomplish an intended intravascular procedure.

In the illustrated embodiment, the connector 115 is coupled to the proximal end of the elongate shaft 114. The connector 115 may comprise a female type Luer fitting configured to be coupled with male Luer fittings of medical components needed to accomplish a diagnostic or therapeutic procedure. The connector 115 may comprise wings to facilitate coupling and decoupling of the medical components. Various other connectors are within the scope of this disclosure.

With continued reference to FIGS. 1 and 2, the primary package 120 comprises a breathable portion, such as breathable layer 116 and a second layer, such as clear film layer 102. The breathable layer 116 is configured to allow passage of a sterilizing gas into the primary package 120 and to prevent passage of microbes into the primary package 120. For example, the breathable layer 116 may be configured to allow passage of ethylene oxide gas, across a wall of the breathable layer into the primary package 120 such that the medical device 110 may be sterilized by the ethylene oxide gas. The breathable layer 116 may comprise any suitable porous material, such as Tyvek®, paper, etc. A surface of the breathable layer 116 may be coated with a thermal or pressure sensitive adhesive such that the clear film layer 102 can be coupled to the breathable layer 116. The clear film layer 102 may be sealed to the breathable layer 116 around the edges of the primary package 120 using heat and pressure or just pressure. A seal 105 may be configured to be peelable such that the primary package 120 can be opened by a healthcare worker to access the medical device 110. The breathable layer 116 is shown to extend from a first end to a second end of the primary package 120. In other embodiments, the breathable layer 116 may comprise only a portion of the primary package 120. For example, the breathable layer 116 may be disposed adjacent one end of the primary package 120. In another embodiment, the breathable layer 116 may be a circular patch disposed along a length of the primary package 120. The clear film layer 102 may be formed from any suitable clear polymer, such as high density polyethylene, linear low density polyethylene, polypropylene, polyester, etc. A label may be adhered to the clear film layer 102 indicating the type of medical device 110 contained within the primary package 120.

In the illustrated embodiment, the support member 108 is disposed within the primary package 120 between the breathable layer 116 and the clear film layer 102. The medical device 110 may be coupled to the support member 108 using any suitable technique such that the shape of the medical device 110 is maintained within the primary package 120. Coupling techniques may include tabs, wires, adhesive, tape, plastic sleeves, etc. The support member 108 may be formed of any suitable non-particulate generating material, such as paper, cardboard, card stock, polymer sheet, thermoformed polymer sheet, etc.

The diffusion inhibitor member 106 is configured to protect or shield the medical device 110 from exposure to VHP or other whole-room disinfecting vapors or gases while still allowing for sterilization of the medical device 110 disposed within the primary package 120 with ethylene oxide gas. The diffusion inhibitor member 106 is disposed over an end of the support member 108, the catheter tip 113, and a portion of the elongate shaft 114. The diffusion inhibitor member 106 is configured to cover a portion L₁ of the elongate shaft 114. In other embodiments, the diffusion inhibitor member 106 may be configured to cover from one inch to a full length of the elongate shaft 114, including from one inch to seven inches of the elongate shaft 114.

Referring to FIGS. 3A-3C, the diffusion inhibitor member 106 is configured as a bag or sleeve having a first wall 122, a second wall 123, an open end 117, a closed end 118, and closed lateral sides 124 such that an internal cavity 107 is created. In some embodiments, the diffusion inhibitor member 106 may be configured as a tube comprising at least one open end. In other embodiments, the diffusion inhibitor member may be open at a proximal and/or a distal end. The diffusion inhibitor member 106 may be formed from any suitable substantially non-porous, material, such as polyethylene, polypropylene, polyesters, foil laminations, paper/polyethylene laminations, vinyl (PVC), nylon, etc. The walls 122, 123 of the diffusion inhibitor member 106 may have a thickness ranging from 0.001 inch to 0.005 inch, including 0.002 inch to 0.003 inch. The thickness of the walls 122, 123 is configured to allow for easily sliding the diffusion inhibitor member 106 over the support member 108 and the medical device 110 while inhibiting diffusion of VHP or any other whole-room disinfecting vapor or gas within the internal cavity 107.

In other embodiments, the diffusion inhibitor member 106 may be configured as bag sized to be disposed over just the medical device 110. The diffusion inhibitor member 106 may also be configured to conform to a shape of the catheter tip 113 such that the shape is maintained by the diffusion inhibitor member 106.

FIG. 4 depicts an alternative embodiment of a diffusion inhibitor member 406. The diffusion inhibitor member 406 is configured to be disposed over a portion of a medical device 410 and coupled to a support member 408 of a packaging system. The diffusion inhibitor member 406 is configured as a polymeric film having an adhesive backing around a perimeter. The diffusion inhibitor member 406 is sized and shaped such that a catheter tip 413 and a sufficient length (L₂), for example at least one inch, of an elongate shaft 414 of the medical device 410 is covered by the diffusion inhibitor member 406 such that the infusion of VHP into the diffusion member 106 is limited. The diffusion inhibitor member 406 may be formed into any suitable shape, such as a circle, square, triangle, rectangle, or any other polygonal shape.

In use, the packaging systems described herein, such as packing system 100 may be used to prevent exposure of medical devices to whole-room disinfecting gases and vapors such that degradation of the polymers used to form the medical devices is prevented. Using the packaging system of FIGS. 1-3C as an example, the medical device 110 may be manufactured according to acceptable techniques and coupled to the support member 108. The diffusion inhibitor member 106 may be disposed over the end of the support member 108 and over the distal end of the medical device 110 such that the diffusion inhibitor member 106 covers the catheter tip 113 and a portion of the shaft 114 of the medical device 110. In other embodiments, the diffusion inhibitor member 106 may be configured to cover other portions of the medical device 110. For example, in some embodiments, the diffusion inhibitor 106 may extend from a distal end of the medical device 110 along the entire shaft 114 of the medical device 110 and may extend such that it extends to, or extends over, the connector 115 of the medical device 110. In other words, the open end 117 of the diffusion inhibitor 106 may be disposed along any portion of the shaft 114 or along any portion of the connector 115. In some embodiments, the diffusion inhibitor may extend to, or beyond, the end of the support member 108. Regardless of the length of the diffusion inhibitor member 106, the diffusion inhibitor member 106 may have an open end 117. In some embodiments, the diffusion inhibitor member 106 is disposed over just the medical device 110. The medical device 110, the support member 108, and the diffusion inhibitor member 106 may be disposed into a primary package 120 through an open end. In some embodiments, the diffusion inhibitor member 106 may be disposed on the outside of the primary package such the diffusion inhibitor member is disposed over a portion of the medical device 110 inside the primary package. The open end of the primary package 120 may be sealed with heat and pressure or pressure forming the packaging system 100. In some embodiments, the packaging system 100 may be packaged in a secondary package system, such as a dispensing box or a shipping box.

Embodiments wherein the diffusion inhibitor 106 comprises a sealed pouch are likewise within the scope of this disclosure. For example, the diffusion inhibitor 106 may comprise a foil pouch that fully encloses the medical device 110.

The packaging system 100 may be exposed to a sterilizing gas, such as ethylene oxide, such that the medical device 110 is sterilized. The presence of the diffusion inhibitor 106 may allow for a sufficient amount of ethylene oxide to reach the portion of the medical device 110 covered by the diffusion inhibitor member 106 (such as catheter tip 113) such that the portion of the medical device 110 covered by the diffusion inhibitor member 106 is sterilized along with the other components of the system.

The packaging system 100 may then be shipped to a healthcare facility and placed in a clinical procedure room, such as an operating room, a diagnostic suite, a cath lab, etc. The clinical procedure room may be disinfected with a whole-room disinfecting gas or vapor, such as vaporized hydrogen peroxide (VHP), formaldehyde gas, or chlorine dioxide gas. The disinfecting gas or vapor may diffuse into the primary package 120. The diffusion inhibitor member 106 may prevent the disinfecting gas or vapor from contacting the portion of the medical device 110 covered by the diffusion inhibitor member 106. The packaging system 100 may prevent degradation of the polymer used to form the medical device 110 because the disinfecting gas or vapor is prevented or limited from diffusion into the cavity 107 of the diffusion inhibitor member 106 and contacting the medical device 110.

In other words, diffusion inhibitor member 106, 406 such as those described herein may be configured such that certain sterilizing agents, such as ethylene oxide gas are allowed to act on the covered portion of a medical device 110, 410 while certain whole-room disinfectants, such as VHP are prevented acting on the covered portion in such as way as to damage the covered portion. As discussed above, the diffusion inhibitor member 106, 406 may be configured with an open end (117 of FIG. 3A) while still inhibiting VHP from acting on the covered portion.

The effectiveness of the packaging system 100 of the present disclosure was tested. Direct evaluation of prevention of VHP contact with the surface of the medical device was not possible due to a lack of a residue left by VHP. Instead, polymeric degradation was measured following repeated exposure of the packaging system 100 comprising the diffusion inhibitor member 106 to VHP. The packaging system 100 was compared to a control packaging system without the diffusion inhibitor member 106. Samples of the packaging system 100 and the control packaging system were exposed to 10 cycles of VHP. The samples included groups oriented with the open end 117 of the diffusion inhibitor member 106 oriented upwards, downwards, and lying flat. Also, two different lengths of the diffusion inhibitor member 106 were tested. A short length covered the catheter tip 113 and one inch of the elongate shaft 114 of the medical device 110. A long length covered the catheter tip 113 and seven inches of the elongate shaft 114. To test for polymeric degradation, lengths of the catheter tips 113 were cut and tested for tensile strength.

FIG. 5 shows the test results. The results of the testing showed that exposure to VHP (without a diffusion inhibitor) significantly decreases the tensile strength of the material of the catheter tip 113 compared to the catheter tips 113 that were not exposed to VHP (p=0.000) where a p value of less than 0.05 shows a significant difference between compared samples. There was no significant difference between catheter tips exposed to VHP with diffusion inhibitors and catheter tips not exposed to VHP (p=0.842). The length of the diffusion inhibitor member 106 was found not to be critical as long as one inch of the elongate shaft 114 was covered (p=0.785). In summary, the test results indicate that the diffusion inhibitor member 106 of the packaging system 100 is effective at limiting the medical device 110 from exposure to VHP.
