Abstract: A surgical instrument includes a rotatable electrical coupling assembly having a first part and a second part that electrically couple and rotate relative to each other. The second part is carried by and rotates with a tube collar coupled to a transducer. A portion of the transducer is inserted through an aperture of the second part, but does not contact the second part. The first part of the assembly may electrically couple to the second part via pogo pins, brush contacts, or ball bearings. Alternatively, the first part may comprise conductive channels formed in the casing. The second part may comprise a rotatable drum with a conductive trace. In some versions, one or more components may comprise MID components. In another version, the rotatable electrical coupling assembly comprises a rotatable PC board and brush contact. Further still, a circuit board may be provided with the transducer inside a transducer casing.

Abstract: An adhesive article comprising a poly(meth)acrylate-based primer layer and methods of making same. The article can include a backing, a primer layer located on a first major surface of the backing, and a silicone-based adhesive located on the primer layer. The primer layer can be derived from a primer precursor comprising poly(meth)acrylate functionalities. The method can include applying a primer precursor onto a first major surface of a backing, the primer precursor comprising a compound comprising poly(meth)acrylate functionalities; irradiating the primer precursor; applying an adhesive on the irradiated primer precursor; and irradiating the adhesive and the irradiated primer precursor to form a primer layer located between the adhesive and the first major surface of the backing.

Abstract: Adhesive articles suitable for use in medical applications include a siloxane-based pressure sensitive adhesive layer, and a breathable conformable backing having a first surface and a second surface. The siloxane-based pressure sensitive adhesive layer is coated on the first surface of the breathable conformable backing, and the second surface of the breathable conformable backing comprises a treated surface. The siloxane-based pressure sensitive adhesive layer can be attached to skin and other adhesive articles can be releasably adhered to the treated surface to form adhesive constructions.

Abstract: The present invention is directed to new methods of determining elongation, tension and applied pressure of elastic bandages comprising tension indicators. In one embodiment, a computer-implemented method of detecting elongation of an elastic bandage (e.g. on a mobile computing device having a processor and graphical user interface) is described. The method comprises receiving image data that includes a digital photograph of an elongated tension indicator of an elastic bandage; analyzing the image data to determine elongation of the elastic bandage by comparing geometric features of the elongated tension indicator to model geometric features that define a predetermined elongation state (such as an unelongated state); and providing output indicia associated with the determined elongation. Also described are various articles, some of which are intermediate articles of the methods described herein.

Abstract: A securement assembly is disclosed that uses a combination of adhesive as well as mechanical fasteners for effectively securing a device to a surface. The securement assembly can be used to protect the surface from the device being secured. The securement assembly comprises an adhering element with a first mechanical fastener and a securing element with a second mechanical fastener, wherein the securing element can serve as both a cover for the adhesive on the adhering element while also providing the securement between the first mechanical fastener and second mechanical fastener.

Abstract: A polymerized microemulsion pressure sensitive adhesive composition is described. The composition has peel adhesion of at least 3 Newtons/100 mm as measured according to a PSTC-1 Test. The composition preferably has a bicontinuous structure of a continuous phase of a hydrophobic pressure sensitive adhesive polymer and a continuous phase of a hydrophilic polymer. The bulk properties of both polymers are retained in the bicontinuous structure. The composition is prepared from a microemulsion comprising a free-radically ethylenically unsaturated polar amphiphilic or hydrophilic monomer or oligomer in the aqueous phase, a free-radically ethylenically unsaturated hydrophobic monomer, having a glass transition temperature suitable for forming a pressure sensitive adhesive, in the oil phase, water, and surfactant.
