摘要： A device and method for separating heavier and lighter fractions of a fluid sample. The device includes a plurality of constituents comprising a container and a composite element in the container. The composite element is a separator comprising a deformable bellows, a ballast mounted to the lower end of the bellows, and a float is engageable with an upper end of the bellows. A fluid sample is delivered to the container and the device is subjected to centrifugation whereby the centrifugal load causes the ballast to move toward the bottom of the tube and causes an elongation and narrowing of the bellows. The separator then moves down the tube and stabilizes in a position between the separated phases of the fluid sample. Termination of the centrifugal load enables the bellows to return to its original condition in sealing engagement with the walls of the tube. The dense formed phase of the fluid sample will lie between the separator and the bottom of the tube, while less dense liquid phase of the fluid sample will be the separator.

摘要： A device and method for separating heavier and lighter fractions of a fluid sample. The device includes a flexible collapsible inner container disposed within a substantially rigid outer container. A closure seals the open top end of the outer container. A filter assembly is sealingly mounted to the open top end of the inner container. The filter assembly includes a filter that permits lighter fractions to pass therethrough, while substantially blocking the heavier fractions. The filter assembly further includes a filter support having a slit valve registered with the filter. The slit valve opens in response to fluid pressure created by the lighter fractions for permitting the lighter fractions to flow therethrough. A fluid sample is delivered to the inner container and the device is subjected to centrifugation whereby the centrifugal load causes the filter assembly to move toward the bottom end of the outer container and thereby enable the lighter fraction of the fluid sample to flow through the slit valve and into the space between the inner and outer containers. The slit valve closes upon termination of the centrifugal load such that separation between the heavier and lighter fractions of the fluid sample are maintained.

摘要： A device and method is provided for separating components of a fluid sample. The device includes a plurality of constituents comprising a container, a liner in the container, a closure for the container and a composite element. The composite element is a seal plug with a density between the densities of the components of the fluid sample is releasably engaged with the container closure and with the liner. A needle cannula is used to deposit a fluid sample in the liner and the entire device is placed in a centrifuge. The centrifugal load causes the seal plug to separate from the closure and causes the liner to expand outwardly against the container. The seal plug migrates into the fluid sample and stabilizes between the densities of the components of the fluid sample. The liner will resiliently return to its initial configuration upon termination of centrifugal load such that the liner sealingly engages the seal plug and separates the components of the fluid sample.

摘要： A system for performing an end-to-side vascular anastomosis. including an anastomosis device, an application instrument and methods for performing a vascular anastomosis. The system is applicable for performing an anastomosis between a vascular graft and the ascending aorta in coronary artery bypass surgery, particularly in port-access CABG surgery. A first aspect of the invention includes a vascular anastomosis staple. A first configuration has two parts: an anchor member, forming the attachment with the target vessel wall and a coupling member, forming the attachment with the bypass graft vessel. The anastomosis is completed by inserting the coupling member, with the graft vessel attached, into the anchor member. A second configuration combines the functions of the anchor member and the coupling member into a one-piece anastomosis staple. A second aspect of the invention includes an anastomotic fitting, having an inner flange over which the graft vessel is everted and an outer flange which contacts the exterior surface of the target vessel. A tailored amount of compression applied by the inner and outer flanges grips the target vessel wall and creates a leak-proof seal between the graft vessel and the target vessel. A third aspect of the invention has a flange to which the graft vessel attaches, by everting the graft vessel over the flange, and a plurality of staple-like members which attach the flange and the everted end of the graft vessel to the wall of the target vessel to form the anastomosis.

摘要： An implantable prosthesis for occluding the opening of a muscle or tissue defect. The implant is laparoscopically deliverable with a system for loading and delivering the prosthesis through a trocar cannula. The prosthesis includes an implantable material with a body portion sufficient to extend across and occlude a defect opening. Antimigration barbs extend from the implantable material to prevent migration of the prosthesis after implantation. A semi-rigid ring may be attached to the material for supporting the body portion. The barbs may be located on the ring. The implantable prosthesis may be provided with a sufficient hoop strength to prevent the body portion from collapsing into the defect opening.

摘要： An instrument for applying clips to a surgical site has an applicator with two jaws which are movable between open and closed positions. A mechanism is provided for feeding the respectively leading clip of a string of such clips between the jaws, whereupon the jaws are closed and the leading clip is cinched as it is being applied to the surgical site. To vary the presentation of the clip, i.e., its orientation relative to the surgical site, the mechanism is mounted so that it can turn about a longitudinal axis of the instrument. In one embodiment, a slide button is provided which can be slid forward and backward with one finger of a user, such translatory movement of the button being converted into a turning movement of the mechanism and consequently also of the clip which is being held between the anvils preparatory to its application to the surgical site. In another embodiment, turning movement is effected by rotating a knob secured to the mechanism.
