CanGaroo® Envelope conforms to implantable devices, creating a stabilized environment that may enhance patient comfort.

CanGaroo Envelope is a naturally occurring bioscaffold intended to securely hold cardiac implantable electronic devices (CIEDs) such as pacemakers and defibrillators when implanted in the body. This creates a stabilized environment that may enhance patient comfort and reduce device migration.1

CanGaroo conforms to the implantable device and remodels into a defined, vascularized pocket that supports and reinforces, while reducing migration of CIEDs.1 Its soft, supple edges may enhance patient comfort, facilitate implantation, and may simplify device removal for exchanges or revisions.1 CanGaroo is designed to address the needs of physicians implanting CIEDs in their daily practice.
