Patent ID: 8529450

Claim:
A device for performing a cutting-balloon intervention on a patient, comprising: a cutting-balloon catheter with an expandable balloon comprising an axially arranged knive; a stent that is pre-mounted to the cutting-balloon catheter on a second expandable balloon; and an integrated unit comprising an OCT sensor and an IVUS sensor located next to the expandable balloon for image monitoring; a drive unit that advances or withdraws the cutting-balloon catheter and simultaneously rotating the OCT sensor and the IVUS sensor; an OCT signal lead and an IVUS signal lead that connect the OCT sensor and the IVUS sensor to the drive unit respectively for rotating the OCT sensor and the IVUS sensor; and a flexible drive shaft in which are the OCT signal lead and the IVUS signal lead, wherein the flexible drive shaft does not rotate and only the OCT sensor and the IVUS sensor rotate to avoid a friction between the cutting-balloon catheter and a vessel wall of the patient.
