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 bronchoalveolar lavage instillation / aspiration system (200) which includes (i) a needleless bronchoalveolar lavage instillation / aspiration device (300) with a barrel member (306) including a barrel lumen (307) having a distal aperture (310) and a self-sealing member (312) configured for maintaining a f luid-disruptable, resealable barrier to the distal aperture (310); and (ii) a catheter asssembly (500) configured to provide a patent path of fluid communication between the instillation / aspiration device (300) and a patient bronchial passage, where the catheter (502) includes a wedging structure (512) configured to engage a patient bronchial passage. In another aspect, embodiments of the present invention may include one or more methods of making and using a system or component described herein.

Description

technical field [0001] Embodiments of the present invention relate generally to medical devices and, more particularly, to systems 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 ventilator (shown sch...
