Embodiment Construction

[0028] figure 2 An embodiment of a non-bronchoscopic bronchoalveolar lavage system 200 partially disassembled is shown in FIG. Other examples of its various components are described in more detail below and may be used with the non-bronchoscopic bronchoalveolar lavage system of the present invention. The system 200 includes a self-contained assembly 300 for fluid installation and aspiration, a manifold assembly 400 and a catheter assembly 500 .

[0029] The drip / aspiration assembly 300 is generally embodied as a syringe 300 . The syringe 300 includes a handle 302 attached to a plunger 304 and a barrel 306, the interior of which includes a barrel lumen. The handle 302 is configured to actuate the plunger 304 distally and proximally along the longitudinal center axis of the barrel 306 . Those skilled in the art will appreciate that actuation of the handle distally increases the pressure within the lumen of the cartridge, while actuation proximally decreases the pressure withi...

Abstract

A catheter assembly configured for use in a non-bronchoscopic bronchoalveolar lavage procedure. The catheter assembly may include an inner catheter member (502) having an inner catheter lumen and an outer catheter member (506) having an outer catheter lumen, where the inner catheter member is disposed longitudinally and coaxially through at least a lengthwise portion of the outer catheter lumen, a distal end portion (508) of the outer catheter (506) includes an atraumatically-shaped disruptable seal (509) - which seal includes at least a pair of overlapping slits that extend at least partially through an internal distal end wall portion of the outer catheter - and where a distal end portion (510) of the inner catheter (502) includes a wedging structure (512) configured to at least partially sealingly contact an inner circumference of a passage in a lower portion of a patient lung.

Description

technical field [0001] Embodiments of the present invention relate generally to medical devices and, more particularly, to catheter assemblies for sample collection during non-bronchoscopic bronchoalveolar lavage procedures. Background technique [0002] Non-bronchoscopic bronchoalveolar lavage (BAL) is a medical procedure commonly used to diagnose associated infections (eg, ventilator-associated pneumonia (VAP)) in patients on mechanical ventilation or otherwise under conditions such as a weakened immune system At risk of lung infection, lung cancer, or interstitial lung disease. VAP is a general term covering pneumonia-associated infections, and patients on mechanical ventilation (ie, connected to a respirator / ventilator or similar mechanical device used to assist breathing) are at higher risk, especially hospital-acquired infection. The non-bronchoscopic BAL procedure described with reference to Figure 1 is performed on an intubated patient 105 on a mechanical ventilato...
