  • Patent number: 5827215
    Abstract: A packing device for use in endoscopic operative procedures is formed of an elongate strip of absorbent, preferably expandable material having a rigid, dry state of a size to permit passage through a narrow endoscopic portal to an internal operative site and having a soft wet state when body fluids are absorbed thereby such that the packing device exposes and isolates tissue to be treated and protects adjacent tissue at the operative site while, in the dry state, is sufficiently rigid to manipulate tissue. A method of packing an internal operative site during an endoscopically performed procedures includes inserting a rigid strip of absorbent, preferably expandable, material through a narrow endoscopic portal and positioning the strip of material at the operative site such that at least a portion of the strip of material absorbs body fluids to become soft and pliable.

  • Patent number: 5824037
    Abstract: The present invention provides modular intraluminal tubular prostheses, particularly stents and stent-grafts, for the treatment of disease conditions, particularly aneurysms. Modular sections of the prostheses, or "prosthetic modules," may be selectively combined to form a composite prosthesis having characteristics which are tailored to the specific requirements of the patient. Each prosthetic module preferably includes one or more standard interface ends for engaging another module, the module/module interface typically comprising ends which overlap and/or lock within a predetermined axial range. Advantageously, the axial length, cross-section, perimeter, resilient expansive force, axial flexibility, liner permeability, liner extensibility, radial conformability, liner/tubal wall sealing and anchoring, and other prosthetic characteristics may be varied along the axis of the composite prosthesis, and also along the axis of each prosthetic module.

  • Patent number: 5823987
    Abstract: A generally cylindrical membrane-type fiber bundle blood oxygenator concentrically surrounds a generally cylindrical blood heat exchanger including a fiber bundle made of thousands of polymer material micro-conduits. A heat transfer fluid such as water is introduced into the upper end of the heat exchanger and flows downwardly around the outside surfaces of the micro-conduits to an outlet. Upper and lower seals of urethane potting compound separate the heat transfer fluid from the open ends of the micro-conduits through which blood flows. A transition manifold at the upper end of the heat exchanger directs out flowing blood radially outwardly to the upper end of the oxygenator fiber bundle. The blood flows downwardly around the outside surfaces of the fibers of the oxygenator fiber bundle to a blood outlet manifold that collects the oxygenated blood.

  • Patent number: 5824060
    Abstract: A natural tissue heart valve includes a tubular wall having an outflow section and valve leaflets which allow flow into the outflow section. A heart valve of this type is subjected to a fixative fluid to provide a first differential fluid pressure across the tubular wall of the outflow section and a second differential fluid pressure across the valve leaflets. The first differential fluid pressure acts outwardly on the tubular wall, and the differential pressures are unequal.

  • Patent number: 5817077
    Abstract: Vaginal epithelium drying is substantially reduced or prevented by reducing the capillary suction pressure of a tampon in early use. This is accomplished by modifying the capillary suction pressure of the surface of the tampon by using hydrophobic components in the tampon, such as hydrophobic fibers and/or hydrophobic cover material. Other means of obtaining a lower capillary suction pressure include increasing the denier of the fibers in the tampon's absorbent core and/or decreasing the density of the tampon.

  • Patent number: 5814096
    Abstract: An aortic valve sizing obturator apparatus for employment in determining the correct size of an aortic annulus. The apparatus includes a cylindrical obturator body with a flange member formed thereabout. At least the under surface of the flange member is of a non-planar, multi-curvate configuration to thereby be complimentary in shape to the annulus of an aortic valve when seated in the annulus during size determination. Within the cylindrical obturator body can be disposed a handle connector to which a handle can be attached during placement of the obturator apparatus within an annulus. The present invention also includes methodology for determining the size of an aortic valve annulus by employing a plurality of differently-sized aortic valve sizing obturators defined above and individually seating them sequentially within the aortic annulus until an obturator that reflects annulus size is located.

  • Patent number: 5810798
    Abstract: Disclosed is an absorbent article having an absorbent core. The absorbent core includes a primary absorbent member and a secondary absorbent member. The primary absorbent member has a fluid distribution rate, expressed as the ratio of a stain area in the primary absorbent member to a stain area in the secondary absorbent member, along a X-Y direction greater than about 1.8 times faster than the secondary absorbent member. The fluid distribution rate is expressed as a ratio of a stain area in the primary absorbent member to a stain area in the secondary absorbent member five minutes after a given volume of test fluid insults the absorbent core. The secondary absorbent member has a substantial portion thereof composed of a non-absorbent polymeric composition. The secondary absorbent member is superposed over a portion of the primary absorbent member.
