METHODS AND DEVICES FOR REMOVAL OF A MEDICAL AGENT FROM A PHYSIOLOGICAL EFFERENT FLUID COLLECTION SITE
First Claim
1. A method for removing an agent from a physiological efferent fluid collection site of a living subject, said method comprising:
- introducing an aspiration device to a target site of said living subject at least proximal to said physiological efferent fluid collection site, wherein said aspiration device comprises an aspiration element and a flow modulator at a distal end of said aspiration element that is configured to converge intersecting fluid flow paths into said aspiration element; and
activating said aspiration device when said agent is at least predicted to be present in said target site to remove fluid comprising said agent from said subject;
to selectively remove said agent from said physiological efferent fluid collection site.

Abstract
Methods and devices for selectively removing an agent from a physiological site, e.g., a physiological efferent fluid collection site, are provided. Aspects of the invention include fluid removal (e.g., aspiration) devices having a fluid removal element and a flow modulator positioned at a distal end of the fluid removal element. The flow modulator is configured to converge intersecting fluid flow paths into the fluid removal element. Also provided are systems and kits for performing the subject methods. The subject invention finds use in a variety of different applications, including the selective removal of both therapeutic and diagnostic agents from a variety of different physiological sites.
