    摘要： 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.

    摘要： Solid materials are separated from hollow body structure aspirates using a filter assembly disposed between an aspiration catheter and an aspirate receptacle. Filter elements having different pore or mesh sizes may be used to size classify the separated solid materials. Multiple filter assemblies may be disposed in parallel or series between the aspiration catheter and aspirate receptacle to provide for different levels of size classification.

    摘要： An aspiration catheter comprises a catheter body having an aspiration lumen therethrough. The distal opening of the aspiration lumen can be modified in various ways or can have the addition of structure in order to disrupt sealing between the port and material being aspirated. Examples of modifications include slots, castellations, zig-zag features, and other geometries which resist sealing of aspirated material. Blades, rollers, vibrating elements, and other structures may be provided within or around the distal end of the aspiration lumen in order to dislodge and disrupt aspirated material which can seal against the opening.

    摘要： Systems, kits, and methods for establishing vascular access are described. A system typically includes a radially expandable sleeve, a dilator, and a guidewire. The methods comprise positioning the guidewire through an initial tissue tract, passing the radially expandable sleeve over the guidewire through the tissue tract to a target blood vessel, and thereafter passing the dilator over the guidewire and through the radially expandable sleeve to effect radial expansion of the sleeve. Use of the sleeve reduces the risk of injuring tissue surrounding the tissue tract by lessening the axial forces imparted to the tissue. Kits comprise at least the radially expandable sleeve together with instructions for use.
