An ostomy bag can include one or more sensors for measuring one or more metrics. An ostomy wafer can also include one or more sensors for measuring one or more metrics. The sensors can be temperature sensors and/or capacitive sensors, for example, and the metrics can include bag fill, leakage, skin irritation, and phase of stoma output, among others.

An apparatus according to certain embodiments generally includes an elongated tubular member having a proximal end and an opposite distal end, and an inflatable balloon surrounding the distal end. The elongated tubular member comprises an outer tube, a non-collapsible inner tube positioned within the outer tube, and a compressible material positioned between the outer tube and the inner tube.

Methods, processes and compositions are provided for improved wound dressings comprising an antimicrobial composition. The wound dressings maintain conformability and strength, as well as antimicrobial performance, upon use after storage.

A pouch having a vent aperture and a filter secured to the pouch with adhesive and covering the vent aperture. The filter includes an adhesive layer comprising the adhesive and an adsorbent layer on the adhesive layer. The filter also includes a gas permeable cover layer secured to the adhesive layer such that the adsorbent layer is covered by the gas permeable cover layer. The gas permeable cover layer has an outer profile and the adhesive layer has a corresponding outer profile which is in register with the outer profile of the gas permeable cover layer. The adsorbent layer is positioned on a first side of the adhesive layer so that a first portion of the first side of the adhesive layer is not covered by the adsorbent layer and the gas permeable cover layer is secured to the first portion of the first side of the adhesive layer.

A catheter according to certain forms generally includes an elongated tubular member and an inlet check valve. The elongated tubular member has a distal end portion configured for insertion into a body cavity comprising soft tissue, and includes an outer tube, a non-collapsible inner tube positioned within the outer tube, and a first compressible material positioned between the outer tube and the non-collapsible inner tube. The inlet check is valve in fluid communication with the first compressible material and is configured to selectively flow fluid into the first compressible material during expansion of the first compressible material.

A wound exudate management system includes a pump for generating negative pressure, a dressing for covering and protecting a wound of a user, a tube including an interior lumen, the tube disposed between the pump and the dressing such that the pump and the dressing are in fluid communication via the interior lumen. The dressing includes an adhesive layer for adhering the dressing adjacent the wound, a wound contact layer, a pressure dispersion layer, a plurality of layers of absorbent material disposed between the wound contact layer and the pressure dispersion layer, a backing layer having a first surface and a second surface, the first surface of the backing layer being adjacent, and in contact with, the pressure dispersion layer and the adhesive layer, and a flexible connector disposed on the second surface of the backing layer.

An ostomy appliance comprises a pouch and a drain. The drain is formed of two walls attached to one another lateral edges to define a channel therebetween and comprises pursing strips to separate the walls when compressed in a direction perpendicular to the lateral edges of the drain. A pursing strip comprises a transverse edge perpendicular to the lateral edges and the transverse edge comprises a notch spanning at least half of the transverse edge. A pursing strip may comprise a line of weakness. The line of weakness may span between side edges of the pursing strip. The line of weakness may be curved. A pursing strip may comprise two converging lines of weakness spanning between upper and lower edges of the pursing strip. The drain may comprise two or three pursing strips. A gap may be provided between pursing strips.

Ostomy wafers, ostomy devices incorporating ostomy wafers, and methods of applying ostomy wafers and ostomy devices are disclosed herein. An ostomy wafer may include an external layer and a convex surface coupled to the external layer. An ostomy device may include an ostomy pouch and an ostomy wafer coupled to the ostomy pouch that includes an external layer and a convex surface coupled to the external layer.

Antibacterial nanofibres and methods for their preparation are described. Antibacterial nanofibres include as-spun alginate nanofibres treated with silver to generate silver-alginate nanofibres. Antibacterial nanofibres provided are useful components of wound dressings, wherein the wound dressings optionally further comprise malodor absorbing agents such as cyclodextrins.

Methods of modifying a medical device and manufacturing a medical device are disclosed. One embodiment of a method of modifying a medical device includes treating a portion of the medical device with cold plasma and functionalizing the plasma-treated portion with a polymer. One embodiment of a method of manufacturing a medical device includes providing a subcutaneous part configured to be positioned subcutaneously in a user and performing a surface treatment on a portion of the subcutaneous part.
