               Integra LifeSciences Closes its Acquisition of the
                 Radionics Division of Tyco Healthcare Group LP

Plainsboro, New Jersey / March 5, 2006 -- Integra LifeSciences Holdings
Corporation (NASDAQ: IART) announced today that it has acquired the assets of
the Radionics Division of Tyco Healthcare Group LP for $80 million in cash,
subject to certain adjustments.

Radionics, based in Burlington, Massachusetts, is a leader in the design,
manufacture and sale of advanced minimally-invasive medical instruments in the
fields of neurosurgery and radiation therapy. Radionics' products include the
CUSA EXcel(TM) ultrasonic surgical aspiration system, the CRW(TM) stereotactic
system, the XKnife(TM) stereotactic radiosurgery system, and the OmniSight(TM)
EXcel image guided surgery system.

As part of the transaction, Integra has assumed the lease on the Radionics
facility in Burlington, Massachusetts, which employs approximately 135
employees, and has entered into transitional supply and distribution agreements
with Tyco Healthcare Group LP for products currently manufactured at Tyco
facilities not included in the transaction.

The transaction offers a number of strategic benefits to Integra LifeSciences:

    o    Increases its global neurosurgery product offering with the addition of
         an ultrasonic surgical aspirator product line, including handpiece,
         tip, and energy delivery designs utilizing magnetostrictive technology.

    o    Positions the company to offer new stereotactic surgery products by
         combining its existing Mayfield(R) and Budde(TM) head-holding and
         retraction products with Radionics' CRW stereotactic head frame.

    o    Secures entry into the radiosurgery/radiotherapy and image-guided
         surgery device business.

    o    Adds to its manufacturing and R&D expertise in electronics,
         ultrasonics, and software.

    o    Enhances the efficiencies of its global infrastructure and distribution
         network through economies of scale and cost synergies.

"This acquisition represents an ideal strategic fit for Integra LifeSciences. It
expands our revenue base and enhances our cash flow and profitability," said
Stuart M. Essig, Integra's President and Chief Executive Officer. "It also
increases our international business significantly as approximately 50 percent
of Radionics' business is outside of the United States."

The CUSA EXcel(TM) ultrasonic surgical aspiration system is a well-recognized medical device used in the selective removal of soft tissue in surgical procedures. The Radionics products are primarily utilized by neurosurgeons in the diagnosis and treatment of cancer and in the treatment of movement disorders. Neurosurgeons use the CRW(TM) stereotactic system, which allows for the positioning of fine instruments in the brain with submillimeter accuracy, for minimally invasive brain biopsies, stereotactic craniotomies, and the placement of radiofrequency probes or stimulating electrodes for the treatment of neurological disorders. The XKnife(TM) system is used in the non-invasive treatment of intracranial brain lesions, and the OmniSight(TM) EXcel system provides neurosurgeons and orthopedic surgeons with enhanced three-dimensional visualization of critical anatomy and the ability to perform less invasive surgical procedures. "The acquisition of Radionics strengthens Integra's product offering in neurosurgery," said Mr. Essig. "The Radionics products provide an exceptional complement to the portfolio of products already offered by Integra LifeSciences. We have great respect for the Radionics team members who have brought so many outstanding technologies to the neurosurgery device market," Mr. Essig added. Tyco Healthcare Group LP sells the Radionics products in over 75 countries, using a network of independent distributors in the United States and both independent distributors and Tyco Healthcare Group LP affiliates internationally. Integra expects to provide detailed guidance regarding the financial aspects of the transaction, including the impact of purchase accounting, and its expected impact on Integra's future financial results on its fourth quarter earnings conference call scheduled for March 6, 2006. Integra LifeSciences Holdings Corporation is a diversified medical technology company that develops, manufactures, and markets medical devices for use in a variety of applications. The primary applications for our products are neurosurgery, reconstructive surgery and general surgery. Integra is a leader in applying the principles of biotechnology to medical devices that improve patients' quality of life. Our corporate headquarters are in Plainsboro, New Jersey, and we have manufacturing and research facilities located throughout the world. We have approximately 1,400 employees.
