For Electronic Implantable Devices

The First. The Only.

CanGaroo Envelope is comprised of acellular biologic material. Porcine small intestine submucosa extracellular matrix (SIS ECM): Designed to create a healthy pocket.1

CanGaroo Diagram

How CanGaroo Works.

CanGaroo is comprised of extracellular matrix which promotes a natural biologic healing response resulting in healthy, vascularized tissue.3

Extracellular matrix regulates the biologic healing response to decrease inflammation and stimulate formation of healthy tissue.3,4 CanGaroo is an extracellular matrix that creates a hospitable environment for host cells to migrate and initiate tissue remodeling.1,5

  • Patients own cells migrate and integrate into the material.5

CanGaroo Benefits.

Remodels into a healthy, vascularized pocket.3



CanGaroo easily conforms to the shape of the CIED. Once implanted, CanGaroo Envelope creates a hospitable environment for the surrounding cells to migrate into the bioscaffold and start matrix turnover.1,5



The extracellular matrix promotes the biologic healing response triggered from the procedure to reduce inflammation and modulate healing.3,4


Within the New Tissue

As remodeling concludes, the CIED is secured naturally with the new tissue.3 The result is systemically connected vascularized tissue that surrounds the device.3

Patients Who May Benefit from CanGaroo Envelope.

Clinical Challenge
How CanGaroo Envelope Helps
De Novo Implants

CanGaroo remodels into healthy, systemically vascularized tissue.3 This may be beneficial for the younger population who may have multiple change-outs in their lifetimes.

Thin Skin Patients

Patients with thin skin may be at risk for erosion and may benefit from an added layer of tissue that secures the device.3

Risk of Migration / Erosion

CanGaroo provides a soft layer around the device which helps anchor the CIED, naturally mitigating risk of migration and/or erosion.3 The CanGaroo may facilitate device implant by providing additional anchoring points.6

S-ICD Patients

CanGaroo provides additional anchoring points at time of device implant resulting in long-term, natural stabilization.3,6 This increased stabilization may also protect both sensing and shocking vector.6

Pediatric Patients

CanGaroo may facilitate abdominal implants by providing additional anchoring points.6 CanGaroo remodels into healthy, systemically vascularized tissue, which may help ease future change-outs.3 This is especially beneficial for the younger population which may have multiple change-outs in their lifetimes.

Higher Calcification Patients

SIS ECM has been shown to naturally resist calcification.5
