Only a minimum volume of implant material (pure titanium sheet, thickness 0,5 mm) is required even in large cranioplasties. In order to avoid "sinking flap" dislocation and to achieve high mechanical strength, the CranioTOP-cranioplasty is placed with its surface edges overlapping the margins of the skull defect (not into it), secured with minimally few screws (CranioDRIVE) and the integrated lugs for positioning. Superpositioning the cranioplasty upon the defect avoids needing major and risky operative procedures, e.g. dissection of the bone edges and the dura as well as duraplasty can be avoided. The cortex remains spared from manipulation
For example, osteolytic parts of the autologous bone can remain in place if additional dissection is too risky or time-consuming.
The minimal implant volume guaranties a local insensivity against patient exposure to heat and cold, which otherwise commonly results in headaches following more voluminous carbide and titanium cranioplasties manufactured by block-milling, casting or LASER procedures (LASER melting).
An accompanying 1:1 acrylic scale model of the individual cranium and its defect is delivered along with each CranioTop implant - allowing a peri-operative "in-vitro" orientation of the implant, therby ensuring the correct "in-vivo" placement.
Full loading capacity of CranioTop cranioplasties is already present immediately following implantation.
"MR-safe" and "MR-compatible":
Full compatibility with CT and MR imaging techniques, particularly in all clinically relevant MRI sequences.

In patients with craniomaxillofacial defects, an HTR implant can be created using a CT scan of the patient's anatomy. This process combines CT Imaging and Rapid Prototyping with individual craftsmanship.
Through HTR, Biomet and Lorenz Surgical carry on our corporate-wide commitment to supply Patient Matched Implants on a timely basis.
Our success is based largely upon open communication between the surgeon, sales associate, and Biomet's HTR specialists. We used the most advanced technology coupled with personal attention in designing and manufacturing precise craniomaxillofacial implants, while setting the industry standard for quick delivery.

( 2.9 / 205 )The X-STOP® IPD® Implant is a titanium metal implant designed to fit between the spinous processes of the vertebrae in your lower back. It is designed to remain safely and permanently in place without attaching to the bone or ligaments in your back.
The oval spacer fits between the spinous processes and the wings are designed to prevent the implant from moving.
Warning: The X-STOP® Implant is manufactured from a titanium alloy of metal. Please inform your doctor if you think you are allergic to titanium or titanium alloy.
Caution: The X-STOP® Impant is manufactured from a titanium alloy which is known to produce artifacts if you undergo an MRI exam.

What Is Tutoplast®?
Tutoplast® is a patented, scientific and technology based process of virally inactivating, preserving and sterilizing human tissue for transplantation. The Tutoplast® Process is recognized as the worldwide leader in preparing allografts for surgery.
Tutopatch® is the first Xenograft tissue that will be offered by Tutogen in the U.S. This introduction follows the successful launch of Tutopatch® in Europe. The product is produced from bovine pericardium harvested from the Company's controlled bovine herd and is preserved using Tutogen's patented Tutoplast® Process, which virally inactivates and preserves the tissue.
Manfred Kruger, President and CEO of Tutogen made the following comment; ``Tutopatch will allow Tutogen to rapidly expand its market share by eliminating dependence on human tissue. This is another step in our drive to become a leader in the bio-implant industry.''
Tutogen Medical Inc. utilizes its patented Tutoplast®process of tissue preservation and viral inactivation, to manufacture bioimplants for neurosurgical, orthopedic, reconstructive and general surgical indications. The Company's Tutoplast®products are sold and distributed worldwide by the Mentor Corporation (NMS:MNTR), Sulzer Medica (NYSE:SM - news), IOP Inc. and through subsidiaries in the U.S. and Germany
Gerard, J. M. and M. Gersdorff (2006). "The Tutopatch graft for transcanal myringoplasty." B-Ent 2(4): 177-9.
OBJECTIVE: This article describes the technique and the preliminary results of transcanal myringoplasty for small or midsized tympanic membrane perforations with the Tutopatch (Tutogen Medical, Inc., Alachua, FL, USA), a xenograft derived from bovine pericardium. METHODS: All procedures started with a Rosen incision. The meatal skin was loosened from the bone up to the fibrous annulus, which was dislocated out of the sulcus, and the tympanic membrane was elevated from the malleus handle. The Tutopatch was placed over the malleus handle, the annulus, and the denuded bone. RESULTS: Eleven patients were included, and follow-up ranged from 3 to 14 months. Ten of the eleven eardrums were successfully closed. One patient developed myringitis 2 months after the procedure. The average air-bone gap at 0.5, 1, 2, and 4 kHz, of all but one patient was less than 10 dB. CONCLUSION: When anatomically feasible, a transcanal myringoplasty with a Tutopatch graft yields similar audiological results compared to fascia temporalis, perichondrium or tragal perichondrium-cartilage, but reduces the surgical trauma, the complications of the autograft harvesting, and the negative cosmetic and psychological impact of this procedure.
Gupta, M., F. Lyon, et al. (2007). "Bovine pericardium (Tutopatch) wrap for hydroxyapatite implants." Eye 21(4): 476-9.
PURPOSE: To evaluate bovine pericardium (Tutopatch) as a wrapping material for hydroxyapatite implants in patients undergoing enucleation for uveal melanoma. METHOD: Prospective cohort study of patients who had enucleation for uveal melanoma between January 2003 and August 2003 were included in the study. Any patient with less than 3 months follow-up was excluded. Enucleation was performed under general anaesthesia followed by insertion of hydroxyapatite implants wrapped in bovine pericardium (Tutopatch). The recti muscles were sutured directly to the wrap. The tenon's capsule and conjunctiva were closed in two layers. A conformer was inserted at 1 week and artificial eye at 2-3 months. The patients were followed up regularly and were assessed for cosmetic result, exposure of implant, and the need for any further surgical procedures. RESULTS: A total of 19 patients (seven male and 12 female) were included in the study. Median age at diagnosis was 63 years (range 38-80 years). Median follow-up was 26 months (range 22-30 months). No patient developed postoperative complications of wound dehiscence. The overall cosmetic result was excellent in all the patients. The rate of postoperative complications compared favourably with published data using other wrapping materials/implants. CONCLUSION: Tutopatch is a safe wrapping material for hydroxyapatite orbital implants in patients undergoing enucleation for uveal melanoma.
Kapan, S., M. Kapan, et al. (2003). "Comparison of PTFE, pericardium bovine and fascia lata for repair of incisional hernia in rat model, experimental study." Hernia 7(1): 39-43.
Incisional hernia is a frequent complication of abdominal surgery developing in 11-20 % of patients undergoing an abdominal operation. Regarding morbidity and loss of manpower, incisional hernias continue to be a fundamental problem for surgeons. In this experimental study, three commonly used mesh materials (Goretex PTFE; Tutoplast Fascia lata; Tutopatch Pericardium bovine) were compared according to effectiveness, strength, adhesion formation, histological changes, and early complications. Three groups, each consisting of 14 rats, have been formed as group A: polytetrafluoroethylene (PTFE), group B: pericardium bovine and group C: fascia lata. Evaluations were achieved at the end of the first and second postoperative week, respectively. Adhesion formation, wound maturation, bursting pressure, and tensile strength were evaluated. No statistically significant difference regarding adhesion formation was observed between groups although adhesion formation was less significant in PTFE and pericardium bovine groups than in the fascia lata group. Bursting pressure and tensile strength values were significantly higher in PTFE group than in the fascia lata group ( P<0.05). No statistically significant difference was observed between groups regarding wound maturation. In this experimental model, PTFE and pericardium bovine were found to be superior to fascia lata in abdominal wall repair.
