A method for onsite hemorrhage control in trauma patients using a portable rapid autotransfusion device can involve recovering a first portion of patient blood from an extravascular space into a fluid reservoir of the device. A negative internal pressure can be applied to the blood. The blood can be conditioned, such as by oxygenating and removing carbon dioxide. The conditioned blood can be returned to the patient intravenously at a rate that matches the rate of blood recovery, ensuring that the net volume of returned blood is maintained substantially equal to the net volume of removed blood.

A closed system for harvesting fat through liposuction, concentrating the aspirate so obtained, and then re-injecting the concentrated fat into a patient comprises as its main components a low pressure cannula having between about 7 to 12 side holes of about 1-2 mm by 2.0 to 4.0 mm, a spring loaded syringe holder with a constant force or coiled ribbon spring to apply a substantially constant pressure over the fill excursion of the plunger, and a preferably flexible collection bag which is also preferably graduated, cylindrical over most of its body and funnel shaped at its bottom, all of which are connected through flexible tubings to a multi-port valve. The multi-port valve has two flutter/duck bill valves which restrict the fluid flow to a one way direction which effectively allows the syringe to be used to pump fat out of a patient and into a collection bag in a continuous manner. After the bags are centrifuged to concentrate the fat, the excess fluids are separated and the valve is re-connected to permit the syringe pump to reverse fluid flow to graft the concentrated fat back into the patient.

Disclosed are apparatus and methods for blood and other biological fluid purification using a membrane with cell containing vascular channel systems and filtration channel systems. Also disclosed are methods of making the apparatus as well as methods of making membranes.

A surgical fluid management system delivers fluid for distending a uterine cavity to allow cutting and extraction of uterine fibroid tissue, polyps and other abnormal uterine tissue. The system comprises a fluid source, fluid deliver lines, one or more pumps, and a filter for re-circulating the distension fluid between the source and the uterine cavity. A controller can monitor fluid retention by the patient.

The present disclosure provides an inventive method of treating deteriorated skin tissue in the face or selected areas of the body, wherein the skin tissue has deteriorated due to aging and/or other factors, by injecting mesenchymal stem cells (MSCs) into these areas, resulting in improving and/or restoring the affected areas. In one aspect, the MSCs are obtained autogenously. In another aspect, the MSCs are minimally manipulated. In yet another aspect, treatment of the skin tissue is carried out using bone marrow concentrate that contains the MSCs. A platelet rich plasma (PRP) may be added to a bone marrow concentrate containing MSCs.

A medical device is disclosed, which is capable of treating lymphedema and reducing a reoccurrence rate after treatment. The medical device includes a tube member that includes a first end portion connected to a first body lumen L and a second end portion connected to a second body lumen P and a pressure-feeding unit that pressure-feeds a body fluid in the first body lumen to the second body lumen.

Peritoneal therapeutic fluid comprising one or more of a biocompatibility enhancing agent (BCA) that is selected from the group consisting of a polyphenolic compound, a metabolite of a polyphenolic compound which is obtained by metabolization in the human or animal body, a salt or a glycoside of a polyphenolic compound.

A surgical apparatus includes: a pipe sleeve section through which gas can circulate; a first seal section provided on a proximal end side of the pipe sleeve section; a second seal section provided on an insertion opening side of the pipe sleeve section; and a sheath provided with, between the first seal section and the second seal section, a hole portion through which gas circulates.

To provide a storage tray in which flexible tubes are to be stored and with which the efficiency of work to be performed after priming can be improved. A storage tray that stores a flexible tube to be attached to a medical apparatus, the flexible tube allowing fluid to flow therethrough. The storage tray includes a tray body that is securable to a predetermined portion of the medical apparatus and in which the flexible tube is storable, and a receiving portion that is included in the tray body and is capable of receiving a priming solution, which is used for flushing the flexible tube attached to the medical apparatus, and storing a predetermined volume of priming solution.
