The present invention is a packaged system that includes a housing to protect a treatment device mounted on a distal portion of a catheter. The housing holds the device suspended such that there is little or no contact between the housing and the device, protecting the device from physical damage and also from exchange of chemical components between the device and the packaging materials, which can occur when a device remains in contact with packaging materials over an extended period of time. A port in the housing allows a controlled environment, for example a vacuum, to be maintained within the housing. A hollow stylet inserted into the distal end of the catheter before the catheter is placed in the housing precludes compression of the catheter and provides an injection port through which the catheter may be flushed with a fluid prior to use, eliminating the need for a separate flushing cannula.

1. A packaged system for treating a vascular condition, comprising: a treatment device;a catheter, a distal portion of the catheter bearing the treatment device;a housing to receive the distal portion of the catheter bearing the treatment device and suspend the device in a protective well, the housing including a first portion rotatably attached to a second portion, the housing defining an opening through the housing into the protective well operable to receive the catheter; anda sealing member operable to encircle the catheter at the opening when the housing is closed;wherein the protective well comprises a central portion, a distal portion and a proximal portion, the distal portion and the proximal portion having narrower cross-sections than the central portion; andwherein the protective well provides a controlled environment selected from the group consisting of a vacuum and inert gas about the treatment device when the housing is closed. 2. The system of claim 1 wherein the housing includes an environmental control port. 3. The system of claim 1 wherein the sealing member is a first sealing member and the system further comprises a second sealing member disposed around an edge of at least one of the first portion and the second portion. 4. The system of claim 1 wherein the housing includes a latching mechanism. 5. The system of claim 1 wherein the housing is fabricated using one or more materials selected from a group consisting of aluminum, stainless steel, polypropylene, polyethylene, polytetrafluoroethylene (PTFE), a nylon/polyethylene blend, and a material that minimizes exchange of chemical components between the housing and a stent during shipment and storage. 6. The system of claim 1 further comprising: a stylet received within a distal end of the catheter. 7. The system of claim 6 wherein the stylet extends within the catheter to at least a proximal edge of the housing. 8. The system of claim 6 wherein the stylet is hollow and wherein the hollow stylet provides an injection port to allow the catheter to be flushed with a fluid prior to use. 9. The system of claim 8 further comprising: a cap removably attached to a distal end of the hollow stylet. 10. The system of claim 1 further comprising an elongate receiving portion extending from the distal portion of the protective well. 11. A packaged system for treating a vascular condition, comprising: a treatment device;a catheter, a distal portion of the catheter bearing the treatment device;a housing including a first portion and a second portion, the first portion and the second portion defining a protective well, the protective well having a central portion, a distal portion and a proximal portion, the distal portion and the proximal portion having narrower cross-sections than the central portion, the distal portion sized to contact and hold a distal tip of the catheter, the housing defining an opening through the housing into the protective well operable to receive the catheter; anda sealing member operable to encircle the catheter at the opening when the housing is closed;wherein the treatment device carried on the catheter is suspended between the two housing portions in the central portion of the protective well; andwherein the protective well provides a controlled environment selected from the group consisting of a vacuum and inert gas about the treatment device when the housing is closed. 12. The system of claim 11 wherein the sealing member is a first sealing member and the system further comprises a second sealing member disposed around an edge of at least one of the first portion and the second portion. 13. The system of claim 11 wherein the housing includes a latching mechanism. 14. The system of claim 11 further comprising: a stylet received within a distal end of the catheter. 15. The system of claim 14 wherein the stylet extends within the catheter to at least a proximal edge of the housing. 16. The system of claim 14 wherein the stylet is hollow and wherein the hollow stylet provides an injection port to allow the catheter to be flushed with a fluid prior to use. 17. The system of claim 16 further comprising: a cap removably attached to a distal end of the hollow stylet. 18. The system of claim 11 further comprising an environmental control port disposed within the housing. 19. A packaged system for treating a vascular condition, comprising: a treatment device;a catheter, a distal portion of the catheter bearing the treatment device;a housing to receive the treatment device and suspend the device in a central portion of a protective well, the protective well having a distal portion for contacting and holding a distal tip of the catheter, the protective well providing a controlled environment selected from the group consisting of a vacuum and inert gas about the treatment device when the housing is closed, the housing defining an opening through the housing into the protective well operable to receive the catheter;a sealing member operable to encircle the catheter at the opening when the housing is closed; anda hollow stylet received within a distal end of the catheter, wherein the hollow stylet provides an injection port to allow the catheter to be flushed with a fluid prior to use. 20. The system of claim 19 further comprising: a cap removably attached to a distal end of the hollow stylet. 21. The system of claim 19 wherein the sealing member is a first sealing member and the system further comprises a second sealing member disposed around an edge of at least one of the first portion and the second portion. 22. The system of claim 19 wherein the housing includes an environmental control port. 23. The system of claim 19 wherein the hollow stylet extends within the catheter to at least a proximal edge of the housing. 24. The system of claim 19 wherein the housing is fabricated using one or more materials selected from a group consisting of aluminum, stainless steel, polypropylene, polyethylene, a nylon/polyethylene blend, polytetrafluoroethylene (PTFE), and a material that minimizes exchange of chemical components between a stent and the housing during shipment and storage.
