Abstract
A process and system provides for atraumatic preparation of morselized Tissue Particles (TP)s, such as Full Thickness Skin Graft Particles (FTSGPs), cartilage particles and other organ tissue particles, in a liquid medium. The resultant tissue product may be a suspension of Tissue Particles in an aqueous solution and containing highly viable cells and may be rapidly prepared at bedside or in the operating room and conveniently delivered to a patient through a syringe or similar applicator. The morselized Tissues Particles may be used for surgical applications including wound healing, cosmetic surgery, and orthopedic cartilage repairs.
Claims18
A method of treating a patient comprising:
- extracting tissue from a donor site of the patient to be treated or from another donor patient;
- forming tissue morsels from said tissue within an aseptic container in a fluid using a system which comprises:
- an atraumatic cutting device including a pair of cutting blades supported in juxtaposition within the container, said cutting device forming said morsels by repeatedly atraumatically slicing the tissue between the cutting blades while maintaining viability of the morsels;
- an opening in the container for permitting fluid communication with a detachable dispensing device;
- a detachable dispensing device for receiving the morsels;
- wherein the formed morsels travel through the opening in the container and into the dispensing device;
- and
- applying the morsels to a portion of the patient's body to be treated using the dispensing device.
