摘要:
A method and a device (10) for reorganizing the fibers of a matrix in a living tissue sheet (S) by inducing controlled mechanical constraints in the living tissue (S) sheet thus causing the fibers of the matrix to be aligned parallel to the strain orientation. The sheet (S) is held in a stretched state until the fibers set in place.

The present invention relates to a method of assembling a single living tissue sheet formed of different cell populations. According to this invention at least two cell populations composing at least two living tissue sheets can be assembled into a single continuous tissue construct. The cells of this construct can also be autologous or heterologous depending on the needs and the type of implant to be transferred in a recipient patient.

摘要:
A method for preparing a human or animal tissue by applying a compressive force to a stack of sheets of living tissue thereby inducing adjacent layers to fuse or adhere to each other. The force is applied in direction normal to the surface of the tissue. A multi-layer tissue produced by the method decribed above can also possess at least two different types of sheets and/or consist essentially of between two and twelve sheets of living tissue. The method can also be used to prepare a planar tissue that can further be incorporated in a multi-layer tissue construct. The methods and tissues described herein are useful for the preparation of engineered tissues.
摘要:
The present invention relates two new methods of improving the functionality of human or animal tissues by physically or biochemically treating the tissue prior to submitting it to different tests or before grafting it to a recipientpatient. Such a treated tissue is therefore rendered having a greater capability to resist to mechanical stress or shows a higher contractility.

The present invention provides a stretcher having a brake mechanism that can be selectively activated to influence the movement of the stretcher supported by an inclined surface. The brake mechanism of the stretcher progressively increases the amount of friction between the stretcher and the surface of which the stretcher is supported to reduce or stop movements of the stretcher. The stretcher further includes a pulling member influencing the position or the activation of the brake mechanism on the stretcher and high friction means associated with the bottom side of the stretcher. The present invention also provides a size reduction mechanism requesting limited storage space for the stretcher when not in use and a foot restraint to secure the feet of the patient on the stretcher and offer additional volume to carry additional material with the patient. A method for braking a stretcher on an inclined plane is also disclosed.
