Disclosed embodiments may relate to negative-pressure therapy, which may collect exudate from a tissue site. In some embodiments, a multi-canister module may allow a single negative-pressure source to draw exudate into two or more canisters. In some embodiments, pressure sensing may take place alongside negative-pressure treatment. In some embodiments, the multi-canister module may be configured to allow for one of the canisters to be changed without interrupting negative-pressure therapy.

An apparatus for treating a tissue site may include a base having a first side and a second side, a first supply port coupled to the base, and a second supply port coupled to the base. The first supply port may be configured to be fluidly coupled to the tissue site and the second supply port may be configured to be fluidly coupled to the second side of the base. The apparatus may also include a plurality of flaps coupled to a portion of the base and configured to generate a force at the tissue site under a supply of negative pressure.

A negative pressure wound therapy device can include a negative pressure source configured to be connected, via a fluid flow path, to a wound, a valve positioned in the fluid flow path and configured to, in an open state, permit supply of negative pressure from the negative pressure source upstream of the valve and, in a closed state, block supply of negative pressure from the negative pressure source upstream of the valve, a flow restrictor positioned in the fluid flow path, and a pressure sensor configured to measure a pressure differential across the flow restrictor. The device can include control circuitry configured to, in a normal operational mode, cause the valve to be in the open state and, in a test mode, perform at least one of a leak test, a flow test, or an excessive pressure test.

Medical devices and methods for endoscopic medical procedures, such as closing a wound or otherwise treating tissue, are described herein. The medical device may include a tube having a distal end and a balloon at the distal end. The balloon may include a collapsed configuration and an expanded configuration. The tube may include an inflation lumen and a suction lumen. The balloon may include an inner layer, an outer layer, a first volume, a second volume, and one or more supports positioned within the second volume. The outer layer may surround the inner layer and may define a plurality of pores through the outer layer. The first volume may be defined within the inner layer and is in fluid communication with the inflation lumen. The second volume may be defined between the inner layer and the outer layer and is in fluid communication with the suction lumen.

Embodiments of apparatuses and methods for providing negative pressure wound therapy to multiple wounds are disclosed. In some embodiments, an apparatus includes a negative pressure source configured to couple via a plurality of fluid flow paths to a plurality of wound dressings. The plurality of flow paths includes a plurality of calibrated leaks. The apparatus also includes a controller configured to determine a total rate of flow in the plurality of fluid flow paths and compare the total rate of flow to a plurality of thresholds associated with the plurality of calibrated leaks to determine one or more operating conditions, such as a blockage in one or more of the plurality of flow paths. An indication of the operating condition can be provided.
