One filter. One tool. One procedure.

Sentry is designed to immediately protect against pulmonary embolism (PE) then bioconvert following the period of transient risk, leaving an open, unobstructed lumen. Its unique design gives you control over filter safety and effectiveness and eliminates the need for (and risks of) a second retrieval procedure.

Product Description

Sentry is designed to bioconvert following the transient risk period, to leave a patent, unobstructed lumen, eliminating the need for retrieval procedures, as well as reducing the associated risks and complications of conventional long-term filters1.

Product Specifications & Sizes

Unique Frame

  1. Cylindrical Nitinol frame designed to minimize migration, perforation, embolization, fracture, and tilt
  2. Self-expanding filter cone formed by 6 arms held centrally by a bioabsorbable filament2
  3. Self-centering filtering cone is designed to reduce the risk of tilting and thereby maximizes filtration capacity

Bioconvertible Design

  • Designed to provide filtration during the period of transient risk (approximately 60 days)3 then bioconvert, allowing filter arms to retract to the IVC wall and restoring an open, unobstructed lumen1,4
  • Bioconversion process allows for protection when you need it, and patency when you don’t 2
  • Eliminates the requirement, cost, and risk associated with IVC filter retrieval

Product Specifications

  • Indicated for IVCs with average diameters between 16 mm and 28 mm
  • Maximum deployed length is 57.7 mm
  • Designed for access via left or right femoral vein, or right jugular vein, with one loading tool
  • Delivered through a 7F ID introducer sheath
  • MR conditional5

System Contents

  • Bioconvertible IVC filter

Clinical Trial

Proven Results

  • The prospective multicenter SENTRY clinical trial demonstrated a high level of safety and effectiveness1
  • ZERO OCCURENCE of device or procedure related symptomatic PE through 24 months while typical published rates range from 0.5 to 6%.1
  • Sentry mitigates common complications of conventional filters, such as tilt, perforation, migration, fracture, and embolization.1
