Abstract
Nanofiber adhesives and their uses with device, such as medical devices, are described. In one embodiment, a nanofiber adhesive layer may be disposed on a surface of a medical device, such as a backing layer of a sensor, for adhesion to a substrate. The nanofiber adhesive layer may allow durable adhesion to the substrate. Other described features may include materials and methods to determine the attachment of the medical device to a patient by determining the adhesive state of the adhesive layer.
Claims18
A device, comprising:
- a backing layer;
- an adhesive layer comprising a plurality of nanofibers attached to the backing layer to couple the device to a patient tissue;
- and
- two or more electrical contacts positioned within or beneath the adhesive layer, wherein the two or more electrical contacts are capable of conducting a current through the adhesive layer or through the patient tissue to provide a signal related to an adhesive state of the adhesive layer.

A medical device, comprising:
- a backing material;
- a sensor or lead attached to the backing material, wherein the sensor or lead is capable of generating physiological data monitored by a patient monitor;
- an adhesive layer comprising a plurality of nanofibers configured to adhere the medical device to a patient tissue, wherein the adhesive layer is attached to the backing material;
- and
- two or more electrical contacts configured to conduct a current through the adhesive layer or through the patient tissue to provide a signal related to an adhesive state of the adhesive layer.
2 more elements
A method of manufacturing a medical device, comprising:
- applying a sensor or lead on a backing material;
- applying an adhesive layer on the backing material, wherein the adhesive layer comprises a plurality of nanofibers configured to adhere the medical device to a patient tissue;
- and
- applying electrical contacts between the backing material and the adhesive layer, or within the adhesive layer, to provide a signal related to an adhesive state of the adhesive layer.
