Patent number: 5449352Abstract: A topsheet for use in body fluid absorptive articles is so improved that collapse and clogging of liquid passages therein may be reliably avoided. The topsheet includes an upper sheet, provided with skin-contacting areas and liquid passages, and a lower sheet provided with skin-non-contacting areas, areas welded to the liquid passages, and exposed areas. The exposed areas are welded to each of the liquid passages around lower openings thereof so as to protect the liquid passage against collapse and clogging. The exposed areas define a skin-contacting surface which rises up into each of the liquid passages without extending above the upper surface of the skin-contacting areas. The upper sheet cooperates with the lower sheet to define cavities extending in the direction of the topsheet thickness.Type: GrantFiled: March 21, 1994Date of Patent: September 12, 1995Assignees: Mitsui Petrochemical Industries, Ltd., Uni-Charm CorporationInventors: Kazunari Nishino, Shigeyuki Motomura, Shizuo Shimizu, Takamitsu Igaue, Tsutomu Kido, Hisashi Takai

Patent number: 5443513Abstract: A beam adapted for implantation within a bone is able to support bending and torsional loading forces applied thereto. The beam has a stiffness defined by a modulus elasticity, which stiffness varies along the length of the beam to match the corresponding stiffness of the cortical bone adjacent the beam after implantation within the bone. The beam is made from an elongated core formed of chopped carbon fibers embedded in a thermoplastic polymer matrix. Encasing the core is a sheath formed of carbon reinforced filament fibers embedded in the thermoplastic polymer which is wound in spiral formation around the core and molded thereto. The winding angle and the sheath thickness along the beam may be varied to vary the modulus of elasticity to match that of the cortical bone adjacent thereto.Type: GrantFiled: December 22, 1993Date of Patent: August 22, 1995Assignee: Howmedica Inc.Inventors: Missoum Moumene, Ruey Y.

Patent number: 5443461Abstract: Diffusional delivery devices are constructed in two or more compartments, each containing a separate drug or other beneficial agent, and each arranged to permit diffusion of the agent out of the device through an individually-characterized agent-permeable wall segment. The diffusion rates of the various agents relative to one another are set and controlled by the parameters of the individual wall segments, such as the surface area of the wall segment, the average thickness of the wall segment, and the permeability of the wall segment for the particular agent. The permeability may be varied by variations in the chemical composition of the wall segment. Using these parameters rather than blending the agents at calculated ratios in a single formulation for diffusion through a single wall permits a wider range of, and greater flexibility in, variation between the diffusion rates of the different agents. This is of value when the simultaneous administration of agents at a specified ratio is desired.Type: GrantFiled: August 31, 1993Date of Patent: August 22, 1995Assignee: ALZA CorporationInventors: Linda E. Atkinson, John T. Dunn, Robert M. Gale, David L. Rivera

Patent number: 5443500Abstract: The intravascular stent intended for implantation in a stenotic area or zone of obstruction of a blood vessel consists of a flat sheet which is perforated to form a kind of a reticulated or lattice type structure with undeformable links and made of malleable material. Said sheet is temporarily rolled up and locked in a spiral with a relatively small diameter (d) on a deflated angioplasty balloon mounted on the end of a catheter and is held in said rolled-up state by a tie laced into overlapping links. Once the device is in place in the restricted area of the blood vessel to be treated and after tie is removed, the rolled sheet is expanded to a desired diameter (D) by inflating balloon and is then held in this expanded state by integrated holding flaps which, after the balloon is deflated, extend through the links and engage the edges thereof under the pressure of the vessel.Type: GrantFiled: April 8, 1994Date of Patent: August 22, 1995Assignee: Advanced Cardiovascular Systems, Inc.Inventor: Ulrich Sigwart

Patent number: 5441482Abstract: A probe for use in collecting liquids entrained with a gaseous component, particularly collecting a patient's blood with entrained gas bubbles from a surgical site for autologous reinfusion. The probe separates the gaseous component from the collected liquid, particularly separating air bubbles from blood cells to inhibit hemolysis, platelet degradation and protein denaturation. An elongated probe body has a distal end to be inserted into the liquid to be collected through an inlet by jet pump action into a centrally disposed mixing chamber. A diffuser is formed within the probe body proximal to and in axial alignment with the inlet and mixing chamber leading to a liquid exit. A jet pump nozzle is formed in the probe distal tip surrounding the inlet in the form of an annular chamber into which pressurized drive fluid is introduced through a distribution channel system extending along the probe body from the proximal end.Type: GrantFiled: May 11, 1994Date of Patent: August 15, 1995Assignee: The Regents of the University of MinnesotaInventors: Cynthia T. Clague, Perry L. Blackshear, Jr.
