Publication number: 20240100308Abstract: PTA catheters and improved PTA methods address problems associated with PTA procedures. One or more stabilizers are activated to hold or fix the PTA catheter at a desired relative position within a support catheter. Timely activation of the stabilizers can prevent deformation of the PTA apparatus during manipulation of the PTA apparatus within biological vessels.Type: ApplicationFiled: January 28, 2022Publication date: March 28, 2024Inventors: Marc Gianotti, Dragana Margeta, Johannes Kulicke, Michael Jetter, Ulf Fritz

Patent number: 11938286Abstract: The current document is directed to usable-length-selectable catheters that employ usable-length-selectable catheters to treat malformations, constrictions, obstructions, lesions, and blockages within patients' blood vessels. The usable length of the shaft of a usable-length-selectable catheter, to which the current application is directed, can be adjusted over a set of lengths prior to and during medical procedures.Type: GrantFiled: June 26, 2018Date of Patent: March 26, 2024Assignee: CTI VASCULAR AGInventors: Marc Gianotti, Ulf Fritz

Patent number: 11865279Abstract: The current document is directed to improved PTA methodologies that significantly decrease the risks of persistent blood-vessel-wall distention and subsequent restenosis and the risks of PTA-induced dissection, hematoma, and pseudoaneurysm when used to treat blood vessels. Similar improved percutaneous-transluminal-interventional methods are used to treat non-vascular vessels. The improved methods include initial selection of balloon length and inflation pressure for initial treatment of primary lesions to minimize the risks of over-inflation and generation of undesirable localized forces during balloon inflation. The improved methods further include higher-pressure treatment of remaining secondary lesions that also minimizes the risks of over-inflation and generation of undesirable localized forces. The improved methods can be practiced using differently sized balloons and conventional instrumentation, but may be facilitated by use of balloon-length-adjustable catheters.Type: GrantFiled: July 1, 2020Date of Patent: January 9, 2024Assignee: CTI Vascular AGInventors: Marc Gianotti, Lisa Gianotti, Stefan Richter

Publication number: 20230270680Abstract: The present disclosure is related to inorganic, biocompatible material compositions for bioactivatable devices, devices, and products comprising transition metal chalcogenides, such as molybdenum sulfides, that can be converted in vivo from a non-bioactive state to a bioactive state upon exposure to physiological conditions, wherein the bioactivated transition metal chalcogenide derivatives, such as molybdenum sulfide derivatives, exhibit copper-chelating activities. Various methods for the application of these compositions for enhancing biocompatibility and reducing or modulating copper-dependent biological reactions are provided.Type: ApplicationFiled: September 30, 2021Publication date: August 31, 2023Applicant: CTI Vascular AGInventors: Ulf FRITZ, Marc GIANOTTI

Publication number: 20210308432Abstract: The current document is directed to length-adjustable catheters and methods that employ length-adjustable catheters to treat malformations, constrictions, obstructions, lesions, and blockages within patients' blood vessels. The length of the shaft of a length-adjustable catheter, to which the current application is directed, can be adjusted over a range of lengths prior to and during medical procedures. In many implementations, length adjustment is accompanied by indications, to the medical provider, of the extent of a length adjustment. The indications may include one or more of visual markings, haptic feedback, radio-opaque markings, and/or other types of indications. In many implementations, the variable-length mechanism of the length-adjustable catheter is mechanically lockable following length adjustment.Type: ApplicationFiled: April 21, 2021Publication date: October 7, 2021Applicant: CTI Vascular AGInventors: Marc Gianotti, Michael Jetter, Martin Rickert, Dragana Gajic, Sabina Silva, Andreas Bodmer, Valentin Nickel, Ulf Fritz

Patent number: 10898696Abstract: A comprehensive multi-functional device platform that can be variably configured by clinician operators for patient-specific anatomies and clinical situations for treating complex and total occlusions is provided. This device platform enables physicians of any skill level to effectively treat the most challenging and complex lesions/occlusions more conveniently in less time. The Functionally Integratable Catheter System (“FICS System”) represents a system of “functional units” that can be configured together to operate synergistically, and comprises at least five main “functional units,” including: (a) FICS Support Catheter; (b) FICS Dilator; (c) FICS PTA Catheter; (d) FICS Lock-Grip Handle; and (e) FICS Steering Hub. Each “functional unit” can be provided in a pre-assembled form by the manufacturer, intended to be configured into variable combinations by clinician operators.Type: GrantFiled: January 11, 2016Date of Patent: January 26, 2021Assignee: CTI Vascular AGInventors: Marc Gianotti, Ulf Fritz, Dragana Gajic

Publication number: 20210001096Abstract: A functionally integratable catheter system comprising functional units that can be assembled to produce different configurations. The functional units include: one or more FICS support catheters; one or more FICS dilators: one or more FICS PTA catheters; and one or more FICS lock-grip handles. Functional units can be provided in a pre-assembled form by the manufacturer, optionally pre-packaged as a device tray, for assembly into different configurations by clinical operators. The configurational adaptability of the FICS platform enables physicians to efficiently address multiple procedural aspects of treatment processes, including lesion access, lesion penetration, guide-wire negotiation, lesion recanalization, and dilation, by providing in situ treatment options, including intraluminal and/or extraluminal recanalization, and enables multi-stage, patient-customized treatments of complex lesions in vivo, including lesion-length-selective, multi-stage angioplasty treatment.Type: ApplicationFiled: July 16, 2020Publication date: January 7, 2021Applicant: CIT Vascular AGInventors: Marc Gianotti, Ulf Fritz, Dragana Gajic

Publication number: 20180325712Abstract: Catheter for delivery of a medical device such as a stent or filter includes an inner tubular member and an outer tubular member movable relative to the inner tubular member. The outer tubular member is disposed at the distal end of the inner tubular member.
