Abstract: A vacuum aspiration control system for use with a vacuum source and an aspiration catheter includes a connecting tube configured to connect the vacuum source with a lumen of an aspiration catheter. An on-off valve is operatively coupled to the connecting tube, and a sensing unit is configured to detect flow within the connecting tube and provide a signal representative of flow. A controller receives the signal to decide whether to open or close the valve. The controller may automatically close the valve to stop flow when flow through the connecting tube is unrestricted, or according to a predetermined timing sequence. The controller can further periodically open a closed valve to determine whether flow has entered an acceptable range. The controller can still further engage pulsed aspiration with a pressure manipulation assembly when flow is restricted or occluded.

An exemplary wound therapy device includes a pump configured to be worn by a user and a controller coupled to the pump and configured to transition the pump from operating in a first operating mode to operating in a second operating mode responsive to a pressure of the wound therapy device satisfying a first pressure threshold. The first operating mode is associated with a first drive voltage that is different from a second drive voltage associated with the second operating mode.

Abstract: To enable an absorbent article to fit easily around the legs when worn and to improve fit. A pad which includes a polymer sheet having a superabsorbent polymer disposed between two nonwoven fabric sheets. Planar-shaped linear embossed grooves that protrude inward in a width direction from each side edge are formed at positions of the polymer sheet on which the groin of a wearer abuts when worn. Standing gathers that rise along a longitudinal direction on a skin side are formed on both side portions on the skin side. Regions that are surrounded by the embossed grooves tend to deform around the legs with the embossed grooves as flexible shafts, so that the polymer sheet fits easily around the legs when worn and fit is improved.

Abstract: A connector for a fluid drainage system having a body defining a drainage lumen extending longitudinally from a distal portion to a proximal portion. The body can include a piston housing and an inlet in fluid communication with a positive air pressure source. A piston is slidably engaged with the piston housing along a transverse axis between a first position and a second position. In the first position, the piston provides fluid communication between the distal portion and the proximal portion of the drainage lumen and occludes fluid communication between the inlet and the drainage lumen. The piston in the second position occludes fluid communication between the distal portion and the proximal portion of the drainage lumen and provides fluid communication between the inlet and the drainage lumen to clear dependent loops, while preventing distal fluid flow into a catheter.

The closure system includes a first portion on the body side wall having first and second closure members defining a gap therebetween and a second portion on the non-body side wall having a third closure member having an enlarged head portion. In an open state, the neck portion is unfolded. In a closed state, the first closure member is folded onto the third closure member with an edge of the first member engaging the enlarged head through the side wall sheet material, and the first, second and third closure members folded over onto the non-body side wall at a tight fold to seal the discharge outlet.

Abstract: The subject matter of this specification can be embodied in, among other things, an indwelling catheter with an integrated coil section. The coil section, in use, is disposed outside of the urethra and can stretch and bend to accommodate various activities of a user by reducing frictional forces and trauma within the urethra. This improved catheter design results in an increase in range of motion and a decrease in pain for the user.

Abstract: According to certain embodiments, a surgical cassette for an ophthalmic surgical system comprises an irrigation conduit that is in fluid communication with a handpiece and carries fluid toward a surgical site. An aspiration conduit is in fluid communication with the handpiece and carries fluid away from the surgical site. An aspiration pump creates a vacuum pressure in the aspiration conduit to draw fluid through the aspiration conduit towards a drain reservoir. A reservoir couples with a pressure-vacuum source to manage the reservoir pressure. A valve is in fluid communication with the aspiration conduit and the reservoir, and provides one or more channels between the aspiration conduit and the reservoir. Each sensor detects a pressure associated with the surgical site. A computer controls the valve in response to the pressure detected by the one or more pressure sensors to mitigate a pressure or volume change.
