Devices, systems, and methods for treatment of an eye alter aspiration flow from the eye in response to an occlusion of the aspiration conduit pathway. Where aspiration is drawn from the eye using a volumetric pump, the pump can be reversed so as to induce fluid reflux from the aspiration conduit pathway into the eye to help clear the occlusion. The pump may vary the reverse flow in response to sensed aspiration pressure or the like, and the reverse flow may be halted before the pressure within the aspiration conduit pathway adjacent the eye significantly exceeds the irrigation fluid pressure and/or the pressure within the eye. Reflux may alternatively be generated by modulating a vent valve disposed between an irrigation conduit pathway and the aspiration conduit pathway.

An anti-clog suction tip apparatus includes a suction tip having a suction opening and an interior defining a suction channel. An ejection wire channel extends to a wire exit opening into the suction channel that is located proximate the suction opening. An ejection wire including a ball tip at an end thereof occupies the ejection wire channel and is transitionable between a retracted configuration and an advanced configuration such that, in the retracted configuration, the ejection wire including the ball tip is retained within the ejection wire channel and does not obstruct suctioning of debris through the suction channel; and in the advanced configuration, the ball tip of the ejection wire does not extend more than three millimeters beyond the suction opening.

This invention relates to a device and method for the vacuum-assisted delivery of drugs through an intact surface membrane of an organ.

Embodiments of the present invention relate to the field of pressurized fluid delivery devices for use in medical procedures. In particular, a fluid delivery pump comprises at least one compressive member configured to apply a force to a fluid reservoir. The at least one compressive member is associated with a flexible envelope, such that the flexible envelope may move the compressive member. The flexible envelope may be substantially air-tight so that it may be pressurized. When a negative pressure is created inside the flexible envelope, the flexible envelope may change volume, applying a force to the at least one compressive member. The at least one compressive member may then apply a force to the fluid reservoir and the fluid is forced out of the reservoir.

A combination therapy pad that includes a first layer and a second layer operatively coupled to the first layer. A fiber-optic array is disposed between the first layer and the second layer. A third layer is operatively coupled to the first layer. The third layer includes a vacuum tube in fluid communication with a vacuum source and a therapeutic fluid tube in fluid communication with a therapeutic fluid source. The third layer provides at least one of vacuum therapy and therapeutic fluid treatment to a wound area.

Systems and methods can be used improve the efficacy of tube thoracostomy. For example, this document provides devices and methods for confirming the proper placement of a chest tube within the pleural space.

A sound suppression system for reducing or eliminating sound produced by the operation of a breast vacuum pump includes a sound suppressing muffler assembly having an air entry port adapted to communicate with an air outlet port of a vacuum pump or other air flow generating device. The sound suppressing muffler assembly also includes a muffler housing defining an internal space communicating with the air entry port, and an opening in the housing leading to atmosphere. The muffler housing has a tortuous air path in the muffler housing. In one embodiment, sound absorbing porous foam structure is disposed in the tortuous air path. The at least one sound absorbing porous structure absorbs sound energy from the air as the air moves through the at least one air path toward the opening in the muffler housing. In further embodiments, a tortuous air path is provided between an air entry port and an opening to atmosphere in the muffler assembly.
