Abstract
Devices and methods relate to inducing or promoting hemostasis. The hemostasis device may include a support layer having a first surface and an opposing second surface. The device may include a layer, the layer disposed on the first surface. The layer may include a target surface configured to contact a target site. The layer may include a monolayer of about 100% graphene or may include laser-reduced graphene oxide. The device may include a sensor configured to measure a level of hemostasis of the target site. The methods relate to a method of manufacturing a hemostatic device including a monolayer of graphene or a layer of laser-reduced graphene oxide.
Claims18
A device configured to promote hemostasis in a target site of a patient, comprising:
- a support layer that is a non-absorbable layer having a first surface and an opposing second surface;
- a layer having hemostatic properties, the layer disposed on the first surface, the layer being a monolayer of graphene or graphene oxide and including a target surface configured to contact a target site;
- and
- one or more sensors configured to measure clot formation on the layer by measuring graphene resistance, the one or more sensors being configured to alert a status of the clot formation.
A device configured to promote hemostasis in a target site of a patient, comprising:
- a support layer that is a non-absorbable layer;
- a layer having hemostatic properties disposed on the support layer, the layer being a monolayer of 100% graphene, the layer including a target surface configured to contact a target site;
- and
- one or more sensors configured to measure clot formation on the layer associated with the target site.
A method for promoting hemostasis in a patient at a target site, comprising:
- applying a hemostatic device to a target site to induce platelet formation, the hemostatic device including:
- a support layer that is a non-absorbable layer having a first surface and an opposing second surface;
- a layer having hemostatic properties, the layer disposed on the first surface, the layer being a monolayer of 100% graphene and including a target surface configured to contact a target site;
- and
- one or more sensors configured to measure clot formation on the layer associated with the target site;
- and
- wherein the applying includes applying the target surface of the layer directly to the target site so that the layer at least partially covers the target site.
