Abstract:
A Surgical retractor, designed in particular for minimally invasive operations, consisting essentially of an elastic plate rolled up about an axis so as to form the side wall of a substantially truncated cone shape, the narrowest cross section of the truncated cone constituting the distal part of this retractor, when the retractor is in place, and delimiting an operating field, the widest cross section of the truncated cone forming the proximal part, through which instruments can be introduced, said plate being able to be rolled up into a substantially cylindrical shape with a diameter smaller than or equal to the narrowest cross section of its truncated cone shape.
Abstract:
A blood sampling system having an in-line sampling member is provided. The member includes a frangible joint located along the length thereof providing an easily openable port for directly sampling a donor's blood during blood collection into a collection bag. In further embodiments, an integral clamping system can be provided with the sampling member for temporarily cutting off flow of blood from a donor.
Abstract:
A surgical staple for a surgical stapling device fitted with a substantially flat back that can deform between a closed position and an open penetration position of the staple, and two spaced-apart pin rows. The back comprises two parts that are hinged with respect to each other. The two pin rows are affixed by the base of the pins to these two parts, substantially lying along axes perpendicular to a plane of each of the two parts. In the closed position of the back a free end of the pins of the two rows converge, but when the back is in the open penetration position, the axes of the pins of the two rows tend to align parallel to each other so as to offer minimal resistance to penetration into tissues and the parts of the back bearing the bases of the pins are separated by a gap larger than in the closed position. The staple is particularly designed to be used with a combined device for plugging and fluidtight puncturing of a wall of a hollow organ.
Abstract:
A fluidthight surgical staple for a surgical stapling device comprises a deformable back that comprises two parts that are hinged with respect to each other and at least four rows of anchoring pins. The back remains substantially flat when the staple is in place, so that it does not protrude from the wall of the organ; when the back is in the open position, the axes of the pins of the two central rows tend to align parallel to each other and the tips of the pins are separated by a gap larger than in the closed position. At least a second row of converging second anchoring pins is placed towards the outer side of each hinged part of the back. The staple is provided with gripping points for keeping the staple in open or closed position.
Abstract:
An adaptable blood processing platform comprises a blood processing device and a ground engaging frame including a shelf to which the blood processing device is secured. The frame supports the shelf for movement between a lowered position and a raised position. The shelf can be supported, e.g., for swinging cantilevered movement about an axis between the lowered and raised positions. The shelf can be supported, e.g., by a scissors linkage assembly coupled to the shelf for lowering and lifting the shelf between a lowered and raised positions. In the lowered position, the center of gravity of the blood processing device is located a first distance above ground, which is conducive for stable storage and/or transport of the platform. In the raised position, the center of gravity of the blood processing device is located a second distance above ground greater than the first distance, which is conductive for set-up and operation of the platform.
Abstract:
A combined device for plugging and fluidtight puncturing of a wall of a hollow organ, comprising a head bearing a surgical staple for the wall of the hollow organ, a fluidtight puncturing system comprising a puncturing device and a hollow channel, a keeping means for bringing the said staple from its open position to its closed position, a support connected to a traction member extending towards the distal part of the device. The device comprises an introducer capable of introducing the head of the device inside an organism. A staple particularly designed to fit this device is also describe.

Abstract:
A method for sterile connection of tubing includes welding the tubing sections together using an efficient laser. The ends of the tubing sections are brought together prior to the initiation of welding, facilitating isolation of interior passage of the tubing sections. The method can be carried out by an apparatus which is relatively inexpensive and compact.
Abstract:
A container for housing body fluids, preferably blood in its component form. The container comprises a body defined by flexible walls having an interior for housing the body fluid. Additionally, a means for allowing selective fluid flow allows the blood components to be expressed from one chamber of the container into another to separate and separately house the blood components. The present invention also provides a method for separating blood into its components and individually storing same.
Abstract:
A method for separating blood into its components and individually storing same is provided. The method has the steps of: providing a container having a body with at least a first and second chamber. Selective fluid communication is also possible between the first and second chamber, and a tube is in fluid communication with the first chamber. The method also has the steps of: passing the blood into the first chamber through the tube; centrifuging the container to separate the blood into plasma, red blood cells and buffy coat within the first chamber; and expressing a portion of the centrifuged blood into the second chamber. In another embodiment, the method for storing blood has the steps of: providing a container with a body having three chambers. The method has steps that include passing the blood into a chamber through the tube; centrifuging the container to separate the blood into plasma, red blood cells and buffy coat and expressing a portion of the separated blood into second and third chambers from the collection chamber.
