Kirigami modification of biomedical tissue reinforcing meshes and matrices for expansile two-to-three dimensional conversion

Provided are intraoperative devices, the devices comprising a substrate having a plurality of discontinuous cuts formed therein, the plurality of discontinuous cuts being formed such that when the substrate is subjected to deformation, the substrate is capable of deformation beyond an initial state so as to achieve a first shaped three-dimensional state. Through design of the cut patterns in 2D, one can locally control the stretchability and elasticity within the substrate. The substrate can then be deformed into a 3D structure that can provide shape and support to reconstructed tissue in the desired regions while also minimizing operative time and cost. Also provided are related methods of using the disclosed devices; the devices can be used in autologous tissue donation procedures as well as prosthetic procedures.

Soft tissue repair grafts and processes for preparing and using same

Soft tissue repair grafts are provided for supporting, covering, and/or retaining an implant positioned in the body of a subject. The grafts are particularly suitable for use for pre-pectoral breast reconstruction with a breast implant or tissue expander. The grafts include positional notches for more accurate positioning in a subject. The grafts also include at least one cuff element which is folded to form a reinforced folded edge for suturing the graft more securely to adjacent tissues than previously known grafts. The grafts also include a plurality of arcuate slots which form a plurality of circular patterns arranged concentrically about a focal point, thereby enabling the grafts to expand without tearing and to conform more closely to the implant and/or adjacent body tissues such as the breast pocket, than previously known grafts. Acellular dermal matrices are particularly suitable for making the soft tissue repair grafts.

Patient-specific craniofacial implants
11504241 · 2022-11-22 · ·

Patient-specific craniofacial implants structured for filling bone voids or planned bone voids in the cranium and face as well as for simultaneously providing soft tissue reconstruction and/or augmentation for improved aesthetic symmetry and appearance of face and skull. Pterional or temporal voids or defects generally result from a chronic skull or lateral facial deformity along with a compromised temporalis muscle or soft tissue distortion from previous surgery. When muscle and fat atrophy occurs in the pterion or temporal face, temporal hollowing deformity generally results where there would be soft tissue but for the atrophy. The patient-specific craniofacial implants with dual-purpose herein are configured to have an augmented region adjacent the temporal region of the face and cranium in order to prevent and/or correct any such temporal hollowing deformity and to utilize this newfound space to strategically embed implantable neurotechnologies for improved outcomes.
