US Patent 11617807 Urinary intermittent catheter

A reusable urinary intermittent catheter comprising: a catheter tube; a funnel connected to the catheter tube; and one or more near-field communication (NFC) tags embedded in the catheter that contain authentication information and validate the authentication information and usage information. The catheter tube may be configured to be inserted into a male or female urethral tract to facilitate drainage of urine from a bladder into a receptacle. The funnel may be curved to facilitate a flow of urine through the catheter tube and slow the flow of the urine exiting the funnel while minimizing splashing of the urine and reducing material strain on the catheter tube when stored with an insertion aid.
