Abstract: A system for aseptic collection of mammalian amniotic fluid. The system includes a cannula having an attachment end and external end. The attachment end provides a concentric opening to a hollow chamber disposed about a central passage. The hollow chamber has a port disposed adjacent to the external end permitting at least a partial suction to be established within the hollow chamber, the attachment end thereby suctionally attached to a surface when the attachment end is disposed upon the surface. The central passage provides access to a central portion of the surface surrounded by the concentric opening of the hollow chamber. An extraction needle is disposed within the central passage of the cannula and presented to the central portion of the surface. The extraction needle penetrates the central portion of the surface and extracts amniotic fluid there beneath. An associated method of use is also provided.

Abstract: Systems, apparatuses, and methods for providing negative pressure and/or instillation fluids to a tissue site. Some embodiments are illustrative of an apparatus or system for delivering negative-pressure and/or therapeutic solution of fluids to a tissue site, which can be used in conjunction with sensing properties of fluids extracted from a tissue site and/or instilled at a tissue site. For example, an apparatus includes a dressing interface or connector that includes a pH sensor, a humidity sensor, a temperature sensor and/or a pressure sensor embodied on a single pad within the connector and proximate the tissue site to provide data indicative of acidity, humidity, temperature and pressure. Such apparatus includes algorithms for processing such data for detecting leakage and blockage as well as providing information relating to the progression of healing of wounds at the tissue site.

Abstract: Provided is a medical device with portions configured for fitting and being retained simultaneously into two cavities on opposite sides of the body of a subject, for example the eustachian tubes or the fallopian tubes. The device may include an elongated member with a central segment and first and second peripheral segments extending therefrom. These segments differ in their intended function and eventual in situ positioning: the two peripheral segments intended for insertion and positioning within the two cavities and exerting their function within the cavities. The central segment serves as a link between two peripheral segments and may also be used for some other functions by its position. The elongated member may have elastic properties.

Abstract: A surgical tool, systems, and method for cleaning an anatomical space is provided. At least one brush is disposed on a shaft extending through a tube. The tube includes a corresponding brush slot for each brush. A motor is operable to rotate the shaft to cause the at least one brush to move from a closed position to a cleaning position. The at least one brush is positioned entirely inside of the tube when in the closed position and at least partially outside of the tube when in the cleaning position. A fluid source is operable to supply fluid to the at least one brush as the at least one brush passes through the brush slot.

Abstract: Collection of biological fluids. At least one example is a polymeric sleeve including: an elongate body that defines a main passageway; an internal chamber defined within the main passageway; a first flange suspended within the internal chamber at a first position along the longitudinal central axis; and an aperture through the first flange, the aperture at least partially aligned with the longitudinal central axis.

Abstract: This disclosure relates to systems for supporting medical fluid bags and related methods. In some implementations, a system includes a curved tray configured to support a medical fluid bag during a medical treatment, the curved tray including a plurality of openings therethrough, a medical fluid collection basin removably coupled to the curved tray and configured to collect medical fluid leaked from the medical fluid bag during the medical treatment, a leak detector coupled to a surface of the medical fluid collection basin and configured to detect fluid as leaked from the medical fluid bag into the medical fluid collection basin, and a control unit configured to receive treatment data related to the medical treatment.

Abstract: A device and method are provided for monitoring access to a patient by a device that withdraws liquid from the patient and/or supplies liquid to the patient, via a flexible line. A vessel access can be monitored during an extracorporeal blood treatment for which the blood of a patient is withdrawn via a flexible arterial line having an arterial puncture cannula, and supplied to the patient via a flexible venous line having a venous puncture cannula. The monitoring device has a line guide for loosely guiding a line segment of the flexible line. By detecting a change in situation of the loosely guided line segment, a conclusion is made as to whether an incorrect vessel access has occurred.

Abstract: A glaucoma treatment system includes a glaucoma drainage device having a flexible tube with distal and proximal ends, and an inserter with a filament that extends beyond the distal end of a rigid elongate member (e.g., rod or inserter tube). The filament is configured to detachably couple a distal portion of the drainage device tube to the elongate member of the inserter. The filament may extend through a wall of the distal portion of the drainage device tube. The filament and elongate member of the inserter can be configured for relative movement to detach the drainage device tube from the inserter. The elongate member can define an internal channel, and the filament can be configured for axial movement in this channel so that the filament may move toward the proximal end of the elongate member to detach the drainage device tube from the inserter. Other tools are described and claimed.

Abstract: A tympanostomy tube placement device has a needle with a tip, and a retainer at the needle tip. The retainer is within and retains by pulling radially inwardly a tympanostomy tube distal flange in a folded configuration extending distally. Movement of the needle tip in the proximal direction causes the adhesive bond to break and the distal flange releases to an unconstrained deployed position. Due to the axial folding of the distal flange its radial dimension does not affect deployment through the membrane.
