Abstract
A system and method for providing vent channel geometries to compensate for compression forces experienced by a septum within an intravascular device.
Claims20
A compression compensating septum device comprising a septum having a proximal end, a distal end, and an outer surface, a distal portion of the outer surface being chamfered, wherein upon compression fitting the septum within an intravascular device a vent is provided between the chamfered portion of the outer surface and an inner surface of the intravascular device.
A method for venting a septum positioned within a catheter adapter of an intravascular device, the method comprising:
- providing a catheter adapter having an inner surface;
- positioning a septum within the inner surface of the catheter adapter;
- providing a vent between an outer surface of the septum and the inner surface of the catheter adapter, the vent having a proximal opening and a distal opening;
- and
- chamfering a distal end of the vent to increase a surface area of the distal opening.
An intravascular device, comprising:
- a catheter adapter having an inner surface;
- a septum positioned within the inner surface of the catheter adapter, the septum dividing the inner surface into a proximal chamber and a distal chamber;
- a vent interposed between an outer surface of the septum and the inner surface of the catheter adapter, the vent having a proximal opening and a distal opening providing fluid communication between the proximal chamber and the distal chamber;
- and
- a compression relief forming a portion of the distal opening of the vent, wherein a surface area of the distal opening is approximately equal to a surface area of the proximal opening.
