Abstract

A connector for use with a lumen device during the cleaning and sterilization of devices is provided. The connector provides fluid communication between a fluid source and the device. In particular, during the cleaning and sterilization cycle, the connection between the connector and the device does not produce occluded areas at the point of connection where the connector is sealably attached to the device.

Claims

1. A method for cleaning or sterilizing interior and exterior of a lumen device, said lumen device having a port that connected to the interior of the lumen device wherein the port has a sealing surface, the method comprising the steps of:

(a) connecting a connector device to the port, said connector having a housing and a pressure actuated member which is movably positioned within said housing, said pressure actuated member defines a passageway to allow fluid flow through the connector;

(b) placing said connector device and the lumen device in a chamber, wherein steps a and b can be performed in any order;

(c) positioning the pressure actuated member in a first position in which said connector is connected to the port and subjecting the lumen device to a fluid so that the fluid contacts the sealing surface of the port thereby treating the sealing surface with the fluid; and

(d) positioning said pressure actuated member in a second position where a piston surface of said pressure actuated member fully engages with the sealing surface when said pressure actuated member is in said second position so as to induce said piston surface to seal with the sealing surface thereby allowing the fluid flowing into the interior of the lumen device, wherein steps (c) and (d) can be performed in either order.

2. The method of claim 1, wherein the step of connecting said connector device to the port comprises connecting to a connection compartment wherein said port is retained in said connection compartment by a locking member.

3. The method of claim 1, wherein the step of subjecting the lumen device to the fluid comprises subjecting said lumen device to a sterilant or cleaning solution.

4. The method of claim 1, wherein the step of positioning said pressure actuated member in a second position comprises allowing a sterilant or cleaning solution to flow into the interior of the lumen device.

5. The method of claim 1, wherein the step of positioning said pressure actuated member in a second position comprises increasing the pressure of said fluid flowing through said passageway so as to move said pressure actuated member from said first position to said second position.

6. The method of claim 1, wherein the step of positioning said pressure actuated member in a second position comprises using a pressurizing fluid, activating a solenoid, or activating a pneumatic device.

7. A method for sterilizing interior and exterior of a lumen device, said lumen device having a port that connected to the interior of the lumen device wherein the port has a sealing surface, the method comprising the steps of:

(a) connecting a connector device to the port and to a source of sterilant, said connector having a housing, and a pressure actuated member which is movably positioned within said housing, said pressure actuated member defines a passageway to allow sterilant flow through said connector;

(b) placing said connector devices and the lumen device in a sterilization chamber, wherein steps (a) and (b) can be performed in any order;

(c) positioning said pressure actuated member in a first position when said connector is connected to the port and subjecting the lumen device to a sterilant so that the sterilant contacts the sealing surface of the port thereby treating the sealing surface with the sterilant;

(d) subjecting the lumen device to reduced pressure; and

(e) positioning said pressure actuated member in a second position,

wherein a sterilant flows through said path way upon application of reduced pressure wherein a piston surface of said pressure actuated member fully engages with the sealing surface when said pressure actuated member is in said second position so as to induce said piston surface to seal with the sealing surface thereby allowing the sterilization fluid flowing through the path way to enter the interior of the lumen device, wherein steps c, d and e can be performed in any order.

8. The method of claim 7, wherein the step of connecting said connector device to the port comprises connecting to a connection compartment wherein said port is retained in said connection compartment by a locking member.

9. The method of claim 7, wherein the step of subjecting the lumen device to a sterilant comprises subjecting said lumen device to a liquid or vapor sterilant.

10. The method of claim 7, wherein the step of positioning said pressure actuated member comprises changing the pressure in said housing, activating a solenoid, or activating a pneumatic device.
