SAVI Brachy - Merit Medical - reduce the burden of cancer

Targeted accelerated partial breast irradiation (APBI) only 2-5 days * reduce interact with patients

SAVI Brachy provides a pillar based organization keep dosimetry methods, designed to maximize the ease of use during the placement, while providing unparalleled dose of custom.Using SAVI tertiary treatment plan can be finished in a short span of 2 days of APBI effective treatment2, significantly reducing the contact interaction between patients and medical staff.

Introduce SAVI nearly
SAVI near by using thin tube (catheter) radiation directly to the tumor resection.Duct expansion gently to adapt to the tumor size and shape of the cavity.A tiny radiation seed through each tube in order to provide accurate dose of radiation, according to the target group of the exact size, shape or position.

The characteristics and advantages

SAVI nearly meet is how to work?

SAVI Brachy - step 1 - place

Place the

SAVI nearly meet source applicator through a small incision in closed position gently inserted into the tumor cavity, the process is usually in the doctor's office.

SAVI Brachy - step 2 - extension

expansion

Catheter gently to conform to the shape of the cavity expansion.This only at the beginning of the treatment.

SAVI Brachy - step 3 - radiation transport

Radiation transfer

Once the catheter is in place, radiation oncologists treatment, twice daily for 2 to 5 days.At the end of catheter connect to the computerized conveying system, the system will be painless delivery to tiny radioactive seeds in each tube.Every time after treatment, radiation sources are completely removed, the body will not remain any radiation between the two treatments.

SAVI Brachy - step 4 - removed

Take out the

After the last radiation treatment, the doctor will shut down equipment and removed by inserting the same initial incision.

Clinical data

Characteristic research:
Use nearly radiation therapy application in tertiary accelerated partial breast irradiation (APBI) is feasible and safe: TRIUMPH - T test preliminary results

Goals and objectives

Main purpose:
The toxicity of 2 years

  • Goal: < 10% of the rate of severe toxic * (grade 3 or above)
  • Results: the three grade N = 3 (1.5%) N = 11 caps

Secondary objective:
2 years of beautiful.

  • Objective: > 80% of good/excellent
  • Results: 97.25% of good/excellent

3 years of local control:

  • Goal: 5% or less recurrence
  • Results: 1% 99% (local control)

The conclusion of the report

Ultrashort breast nearly after radiotherapy on dosimetry is feasible, and can achieve excellent short-term tolerability and low toxicity.
