breast tissue expanders

Breast Tissue Expander Options


Revolutionary dual-port design and integral drain allow for less invasive – non-surgical – draining of serous fluid

Designed to mitigate key risks associated with breast
expansion and ultimately reduce reoperation rates

Only tissue expander with an integral drain providing direct
access to the periprosthetic space where fluid can accumulate

Allows for diagnostic fluid sampling to enable a faster
treatment response


The unique feature of the AlloX2 provides surgeons easy access to the periprosthetic space without altering any of the other characteristics of a tissue expander. While one does not plan to experience a postoperative complication, a valid question in light of the availability of the AlloX2 is why one would forego utilizing a device that facilitates treatment thereof.

Soft, refined design allows for
gentle and more comfortable expansion

Soft, pliable shell results in less friction upon insertion

Designed without ridges or rings for improved comfort

Port location is designed to aid in predictable,
consistent expansion

AlloX2 is designed to reduce the financial risks associated with breast reconstruction

Managing the risks of post-operative fluid accumulation


Obesity (BMI >30) and use of an Acellular Dermal Matrix (ADM) have been identified as major risk factors for seroma4

  • ~40% of adult patients in the US are obese5
  • An ADM is used in over 60% of breast reconstruction cases6

A seroma increases the risk of major infection in breast reconstruction patients

  • Risk of infection is 4x higher in patients who develop a seroma4
  • Risk of expander loss caused by infection is 6.7x higher in patients who develop a seroma4

Clinically relevant infections with poor salvage rates occurred in nearly 1/5 of seroma patients (18.8%)4


78% of infections
require explantation4

Re-operation costs can run upwards of +$20K,7 which may not be covered by insurance if within 30 days of initial surgery8

Clinical Outcomes

AlloX2 improves salvage rates & clinical outcomes10

Retrospective review of 112 consecutive patients

63 patients (53.6%) Mentor Artoura

49 patients (43.7%) AlloX2

173 breasts with smooth tissue expanders (2016-2017)

AlloX2 Stats:

  • 8% seroma rate
  • All successfully drained in clinic through AlloX2

100% Surgeon Satisfaction using AlloX211

In a clinical study with 40 primary reconstructive patients, the AlloX2 was deemed successful in treating seromas and should be considered a tool for noninvasive treatment of common complications of tissue expander-based breast reconstruction.
