Embodiment 1

[0137] Functional dimensions of the FICS system

[0138] Figure 15 is a dimensional illustration of the FICS system in the fully extended "CTO expander configuration", showing the relative dimensional interoperability of the various "functional units" and "functional subunits" for ease of reference. exist Figure 15 In , the imaginary dimensional values ​​of the components used in the "FICS CTO dilator configuration" are designated as "component specific reference designation abbreviations" (LG, SC, PTA, DIL and CTO) and "specific functional dimension reference designation abbreviations " (TL, UL, ML, RL, BL, OL, SL, TiL). "Functional Dimension Specific Reference Number Abbreviations" represent the respective lengths of the FICS members, as shown in Table 1 of Example 1 below. In addition, Table 2 provides the calculations for the respective components (marked in Figure 15 in; listed in Table 1), the various formulas of "functional dimensions" listed in the first column ...

[0146] FICS total length TL(A)

Embodiment 3

[0149] FICS effective length UL(B)

[0150] "Usable Length" (UL) refers to the indwelling / working length portion of the FICS system or individual functional units. UL is related to the distance between the entry point (patient entry site) and the target treatment point accessible by the FICS system. The FICS system can provide different predefined UL ranges corresponding to the individual components of the FICS system used to treat a large number of complex lesions and / or CTOs. As an example, the effective length of each member was used for two specific treatment configurations: (a) FICS CTO dilator configuration (Table 3); and (b) FICS LLS PTA configuration (Table 4). In Table 5, the clinically appropriate entry length is related to the distance measured from the most commonly used (pre-defined) patient entry point to the putative target site (distance beyond the putative lesion located in the pre-defined target zone). The effective length UL portion of the components of th...

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 occlusionsis 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 (110); (b) FICS Dilator (130); (c) FICS PTA Catheter (140); (d) FICS Lock-Grip Handle (120); and (e) FICS Steering Hub (150). Each 'functional unit' can be provided ina pre-assembled form by the manufacturer, intended to be configured into variable combinations by clinician operators.
