Abstract

A filter system, comprising an elongate filter body defining a lumen and having a proximal end and a distal end. A valve can be provided defining a lumen and having a reversibly sealable opening for unidirectional flow of a fluid through the lumen. The valve can be adjoined proximal the distal end of the elongate filter body, wherein the elongate filter body filters the unidirectional flow of the fluid passing through the lumen of the valve and the lumen of the elongate filter body.

Claims

1. A filter system, comprising:

an elongate filter body including an expandable filter region defining a lumen; and

a valve defining a lumen and having a reversibly sealable opening for unidirectional flow of a fluid through the lumen, the valve adjoined the expandable filter region of the elongate filter body, wherein the expandable filter region filters the unidirectional flow of the fluid passing through the lumen of the valve and the lumen of the expandable filter region.
