Official Title: Distal Protection Combined With Velocity in Coronary Arteries and SVBG Registry.

Further study details as provided by Cordis Corporation:

Primary Outcome Measures:
  • clinical success of the AngioGuard™ device combined with the Bx Velocity™ stent [ Time Frame: 1 month ]

Secondary Outcome Measures:
  • successful placement and retrieval without embolic occlusions of vessels distal to the position of the device [ Time Frame: post-procedure ]
  • overall survival rates [ Time Frame: 1 month and 6 months ]
  • device evaluation [ Time Frame: post-procedure ]

Enrollment: 100
Study Start Date: May 2000
Study Completion Date: June 2002
Primary Completion Date: February 2002 (Final data collection date for primary outcome measure)

AngioGuard™ device and Bx Velocity™ stent
Device: emboli capturing guidewire device combined with stent
AngioGuard™ device and Bx Velocity™ stent
Other Names:
  • emboli capturing guidewire device
  • PTCA

Detailed Description:
This is a prospective, non-randomized, multi-center trial. Patients will be treated with the AngioGuard™ device and Bx Velocity™ stent and will be followed for six-months post-procedure.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Unstable angina pectoris (Braunwald classification B & C, I-II-III, native vessels)
  • or lesion located in the SVG;
  • Single de novo or restenotic lesion requiring treatment in a major native coronary artery or saphenous vein graft;
  • The vessel diameter to place the AngioGuard™ device in must be > 3 and < 5.5 mm (6.5 when the 7mm AngioGuard™ is available);
  • Target lesion stenosis is >50% and <100% (TIMI 1).

Exclusion Criteria:

  • A Q-wave or non-Q-wave myocardial infarction within the preceding 72 hours unless the CK and CK-MB enzymes are back to normal;
  • More than one coronary artery is 100% occluded;
  • Patient has unprotected left main coronary disease with > 50% stenosis;
  • Patient has an ostial target lesion;
  • Significant (>50%) untreated stenosis proximal or distal to the target lesion that will be treated during the procedure, since this may require revascularization or impede runoff;
  • Ejection fraction <30%;
  • Totally occluded vessel (TIMI 0 Level).
