¹Includes data from ve subjects who were enrolled twice in the
study, for the treatment of separate de novo CTO lesions.
Primary Endpoints
The primary endpoint for the study was dened as procedure
success through discharge or 24 hours post-procedure, whichever
came rst. Procedure success was dened as angiographic
visualization of any guidewire in a position either distal or proximal
to the occlusion depending on the route of access, and absence of
in-hospital MACE (cardiac death, target lesion revascularization, or
post-procedural MI dened as CK-MB ≥ 3x ULN).
Summary of Primary Endpoints
The study primary endpoint result (75.3%) met the predetermined
performance goal.

Secondary Endpoints
The secondary endpoints include:
• Frequency of successful recanalization (dened as
angiographic conrmation of crossing CTO and restoring
blood ow to the aected area).
• Frequency of MACE through discharge or 24 hours post-
procedure, whichever comes rst (in-hospital follow-up),
and at 30 days post-procedure (MACE components are also
reported separately).
• Frequency of clinically signicant perforation (dened as
any perforation resulting in hemodynamic instability and/
or requiring intervention including pericardiocentesis,
embolization, prolonged balloon occlusion, stent graft, or
comparable therapy).
• Procedural success according to crossing technique.
• Technical success.

Conclusion
In a multicenter, prospective registration trial, procedural success
was achieved in a high lesion complexity patient population (e.g.,
94.7% severely calcied lesions) using contemporary technique and
application of dedicated CTO guidewires, microcatheters and guide
catheter extensions
CLINICAL PROCEDURE
The GuideLiner catheter should be used by physicians trained on the
procedures for which it is intended. The techniques and procedures
described do not represent ALL medically acceptable protocols, nor
are they intended as a substitute for the physician’s experience and
judgment in treating any specic patient. All available data, including
the patient’s signs and symptoms and other diagnostic test results,
should be considered before determining a specic treatment plan.
PACKAGE CONTAINS:
1x Catheter
OTHER ITEMS REQUIRED BUT NOT PROVIDED:
• Guide catheter with an inner diameter large enough to
accommodate the specic model of GuideLiner catheter in
use
• Y-adaptor with hemostasis valve (Tuohy-Borst type)
• Guidewire with diameter ≤ 0.014" / 0.36mm
• Sterile syringe (for ushing)
• Sterile heparinized saline (for ushing)
PREPARATIONS FOR USE
1. Prior to use, carefully inspect the GuideLiner packaging and
components for damage.
2. Using sterile technique, transfer the dispenser coil with the
GuideLiner catheter into the sterile eld.
3. Remove the GuideLiner catheter from the dispenser coil and
thoroughly ush the lumen of the GuideLiner catheter from the
distal tip with sterile, heparinized saline solution.
4. Wet the distal section of the catheter with heparinized saline
to activate the catheter's hydrophilic coating.
DEPLOYMENT PROCEDURE
Deploy the GuideLiner catheter according to the following steps:
1. Secure the previously inserted guidewire and backload the
distal tip of the GuideLiner catheter onto the guidewire and
advance until the catheter is just proximal to the hemostasis
valve.
2. Open the hemostasis valve and advance the GuideLiner
catheter through the hemostasis valve and into the guide
catheter.
3. Under uoroscopy, advance the GuideLiner catheter beyond
the distal tip of the guide catheter and into the desired location
within the vessel.
WARNING: Never advance the GuideLiner catheter into a
vessel with an eective diameter less than 2.5mm. Vessel
injury, ischemia, and/or occlusion may result. If pressure
in a vessel dampens after inserting the GuideLiner
catheter, withdraw the catheter until the pressure returns
to normal.
WARNING: Due to the size and non-tapered tip of the
GuideLiner catheter, extreme care must be taken to avoid
vessel occlusion and damage to the wall of the vessels
through which this catheter passes.
4. Using uoroscopy, conrm the desired position of the
GuideLiner catheter in the vessel.
5. If performing an interventional procedure, backload the
interventional device over the existing guidewire and advance
the device through the guide catheter and GuideLiner catheter
into the desired vascular space.
NOTE: If a second wire is used during the intervention
and encounters resistance within the guide catheter, pull
the wire back several centimeters and slowly readvance.
6. Tighten the Y-adaptor hemostasis valve securely on the
proximal shaft of the GuideLiner catheter to prevent back-
bleeding.
7. Perform the catheterization procedure. After completing the
procedure, remove the GuideLiner catheter prior to removing
the guide catheter from the vessel.
8. Dispose of the GuideLiner catheter following standard hospital
procedures.
