Medical procedure trays and related methods are provided to accommodate joining a first non-sterile medical device with a second sterile medical device and maintaining required sterilization of the second sterile medical device to perform an associated medical procedure. One example of such medical procedures includes biopsy of a bone and/or associated bone marrow using a non-sterile powered drive and a sterile biopsy needle or biopsy needle set. Medical procedure trays and related methods may also be provided for use during aspiration of bone marrow and/or stem cell transplant procedures. Each medical procedure tray may include a containment bag or sterile sleeve. A coupler assembly, one or more sharps protectors, a biopsy sample ejector and/or associated ejector funnel may also be included. Some medical procedure trays may allow engaging a non-sterile powered driver with one end of a coupler assembly and sealing the non-sterile powered driver in a sterile sleeve or containment bag without compromising sterility of other components in the medical procedure tray.

Described is an arthroscopic bone transplanting procedure for transplanting a section of a first bone to a second bone. The described procedure is particularly useful for the treatment an anterior shoulder instability, where the first bone is the coracoid and the second bone is the glenoid. Also described is a kit of medical instruments particularly useful in such a procedure.

Methods for reducing or preventing transplant rejection in the eye of an individual are described, comprising: a) performing an ocular transplant procedure; and b) implanting in the eye a bioerodible drug delivery system comprising an immunosuppressive agent and a bioerodible polymer.

Systems and methods for performing transcatheter coronary artery bypass grafting procedures are provided. The methods generally involve passing the graft from the aorta to the coronary artery through the pericardial space. The systems include poke-out wires, a coring device, and devices for forming anastomoses at the proximal and distal ends of a vascular graft.

The invention provides compositions and methods useful for the depletion of CD117+ cells and for the treatment of various hematopoietic diseases, metabolic disorders, cancers, and autoimmune diseases, among others. Described herein are antibodies, antigen-binding fragments, ligands, and conjugates thereof that can be applied to effect the treatment of these conditions, for instance, by depleting a population of CD117+ cells in a patient, such as a human. The compositions and methods described herein can be used to treat a disorder directly, for instance, by depleting a population of CD117+ cancer cells or autoimmune cells. The compositions and methods described herein can also be used to prepare a patient for hematopoietic stem cell transplant therapy and to improve the engraftment of hematopoietic stem cell transplants by selectively depleting endogenous hematopoietic stem cells prior to the transplant procedure.

The transplant sucker is composed of body of sucker and vacuum connection. Through air passage in the body of sucker, the vacuum connection is connected to vac sorb holes on back plane of the body of sucker. There is buffering cover layer on the back plane. The invention makes transplanting procedure stable and reliable. The invention solves crushing issue of material occurring in procedure for testing solar cell.

The invention discloses a polymer filled bone material and a preparation method thereof. A polymer filled bone material with bone material gaps filled with polydimethylsilane (PDMS), thereby achievingthe goals of enhancing the elasticity modulus of the bone material and maintaining the characteristics of the bone material. Great clinical values are realized on the improvement and mass productionof bone graft materials used in bone graft surgeries. Meanwhile, the invention further discloses the polymer filling bone material obtained by adopting the polymer filling bone material and a preparation method thereof.

Provided are a transplant device that has achieved a decrease in space for the device, a computer program and a transplant method, and a transplant device, a transplant system, a transplant method, and a computer program which enable efficient selection and transplantation with a simple configuration. The transplant device is provided with: a first holding unit that holds a flat board-like culturemedium in which a plurality of plants is planted in a row direction and column direction; a second holding unit that holds a flat board-like cultivation panel so as to be parallel with the culture medium, the cultivation panel being provided with a plurality of plant holding holes in the row direction and the column direction; a determination unit that determines, on the basis of a predeterminedtransplant algorithm, a procedure for transplanting from the culture medium to the holes in the cultivation panel; a moving unit for moving the first holding unit or the second holding unit so that the plants in the culture medium corresponding to the transplant procedure determined by the procedure determination unit and the cultivation panel holes are positioned vertically; and a transplant unitthat, after the movement, transplants the plants by having the plants drawn or pushed into the holes, using a transplant arm that can be moved up and down in a direction perpendicular to the culturemedium and the cultivation panel.

A method for organ and tissue chimerization using bone marrow cellular treatment, which avoids rejection of transplanted organs and diminishes or suspends the use of immunosuppressant drugs in patients subjected to transplant procedures. The method comprises washing the organ in an electrolyte solution. A further step of washing the organ in a wash solution. The organ is then placed in a culture solution and incubated with bone marrow cells.

The invention discloses a method for preparing an isolated hair follicle in a process of treating scar by hair follicle stem cell transplantation. The method comprises the following steps: extractionof hair follicles, separation of the hair follicles, completely separating the hair follicle units into single hair follicles under an electron microscope, and keeping the extracted skin appendages such as sebaceous glands, sweat glands and the like as far as possible; for scars in a smooth hairless area, removing lower 1/3 of hair papilla, so that the hair follicle could not enter the next growthcycle, and no final hair grows in the scar area; in vitro culture of the hair follicles, putting the isolated single hair follicle into a special culture solution for culturing for later use; planting the hair follicle stem cells in a specific area of the scar on the basis of hair follicles. According to the method, through a hair follicle in-vitro culture technology, the single hair follicle isseparated and inactivated by adopting a separation method different from a hair transplantation operation, and is cultured in the special culture solution, so that growth and proliferation of hair follicle stem cells are facilitated. The method can achieve purposes of inhibiting scar hyperplasia, softening and repairing scars, and removing and beautifying scars.

The current invention relates to an implantable device, system, method, and computer readable medium comprising computer executable components for detection of rejection of a cardiac allograft. Acute rejection and chronic rejection are the leading cause of death in heart transplant recipients post transplant. The current invention seeks to address this problem by providing methods, devices, systems and computer readable media comprising computer executable components to monitor the efficacy of immunosuppressant therapy and evaluate the degree of rejection in a cardiac allograft. To provide this functionality, an implantable device comprises sensors which measure physiologic parameters at specified intervals after the transplant procedure. These measured parameters are subsequently compared with baseline parameter data to detect rejection of the cardiac allograft.
