Abstract: 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.

Abstract: 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 four main “functional units,” including: (a) FICS Support Catheter; (b) FICS Dilator; (c) FICS PTA Catheter; and (d) FICS Lock-Grip Handle. Each “functional unit” can be provided in a pre-assembled form by the manufacturer, intended to be configured into variable combinations by clinician operators.

Abstract: In accordance with the present disclosure there is provided an angioplasty catheter system and method for using such angioplasty catheter system that facilitates controllably delivering focalized pressure to complex lesions. The angioplasty catheter comprises an elongated member having a proximal end, a distal end, and at least one lumen extending at least partially through the elongated member, and an inflatable member proximally affixed to the elongated member adjacent to the distal end and in fluid communication with the at least one lumen, the inflatable member having a radius R and including at least two lobes (32,34), the at least two lobes separated from each other by one or more waist portion (44) defined by two legs (91,92) and a waist portion length (37) such that upon pressurization, radial stress around the waist portion is directed away from the vessel wall and focalized into the lesion at an angle about perpendicular to the legs (91,92) of the upper and lower base of the waist portion (44) creating variable directional forces from to (70,73) to (70′, 73′) resulting in the preferential formation of lesion fractures at the waist of the inflatable member.

IPC: A61M25/10
Abstract: 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.
