“…The PTN rheological behavior within a viscous deformation region is consistent with that shown by the wet bone matrix ex vivo [67]. Of particular note is that the PTN body, having a certain pore size distribution, possesses a prominent capillary effect, which is sufficient to hold tissue fluids inside it [68]. This implies the PTN implant also has the possibility to transfer over most of the applied physiological loads via redistributed hydrostatic pressure, just as spongy bone tissue does.…”

Porous TiNi alloys fabricated by self-propagating high-temperature synthesis (SHS) are biomaterials designed for medical application in substituting tissue lesions and they were clinically deployed more than 30 years ago. The SHS process, as a very fast and economically justified route of powder metallurgy, has distinctive features which impart special attributes to the resultant implant, facilitating its integration in terms of bio-mechanical/chemical compatibility. On the phenomenological level, the fact of high biocompatibility of porous SHS TiNi (PTN) material in vivo has been recognized and is not in dispute presently, but the rationale is somewhat disputable. The features of the SHS TiNi process led to a multifarious intermetallic Ti4Ni2(O,N,C)-based constituents in the amorphous-nanocrystalline superficial layer which entirely conceals the matrix and enhances the corrosion resistance of the unwrought alloy. In the current article, we briefly explore issues of the high biocompatibility level on which additional studies could be carried out, as well as recent progress and key fields of clinical application, yet allowing innovative solutions.

“…This problem might be solved using materials based on titanium nickelide, which exhibit superelastic hysteresis properties at body temperature [6]. High stability of the physical and mechanical characteristics of such alloys over a long period of time and the capacity to programmatically control the shaping parameters allow to create implants that perform their specific functional task and become an integral part of the body's structure.…”

Imposition of a classic colostomy does not allow to control the passage of intestinal discharge. This shortcoming provides rationale for development of new materials for implants, as well as new techniques for valve formation.The aim of the study is to assess the possibility of using spherical implants based on titanium nickelide both wrapping and non-wrapping the serous-muscular layer of the intestine for valve formation during colostomy.Materials and Methods. Experiments were performed on 45 male Wistar rats with the average body weight of 587±10 g. Depending on the type of surgical intervention, all animals were divided into three groups. In the control group (n=15), a classic end colostomy was formed without spherical implants. In test group 1 (n=15), colostomy was formed using spherical implants made of titanium nickelide with wrapping the serous-muscular layer of the intestine; in test group 2 (n=15), the same procedure was performed without wrapping the serous-muscular layer. To assess the clinical condition of the animals, the authors monitored the body weight dynamics, food and water consumption, signs of discharge from the stoma, and recorded complications. The animals were euthanized on day 7, day 30, and day 60 of the experiment. During necropsy, the condition of the abdominal organs was assessed macroscopically with a special attention to the signs of adhesions. The severity of the inflammatory process in the area of surgical intervention was assessed histologically.Results. The survival rate in three groups was 100%. In the group with the formation of a colostomy non-wrapping the serous-muscular layer, a good effect of regeneration in the stoma area was shown, the connection of the skin flap and the intestinal wall was complete. Macroscopically, adhesions and inflammatory processes of the peritoneum in the control and two test groups were minimal.Conclusion. The present study shows the advantage of experimental modeling of colostomy using spherical titanium nickelide implants non-wrapping the serous-muscular layer of the colon compared to classical formation of colostomy. At that, wrapping the serous-muscular layer of the colon using spherical titanium nickelide implants is behind classical formation of a colostomy.
