  • Patent number: 7322358
    Abstract: A female condom is provided that includes a pouch of resilient membranous material and a hydrophilic cling mechanism. According to an embodiment of the invention, the cling mechanism includes three or more foam cling elements attached to an outer surface of the pouch. Upon insertion, the foam cling elements cling lightly to vaginal walls proximate a transition zone between the vagina's introitus and its rugated internal tissue. The foam cling elements may be shaped to permit them to nestle into a user's rugated internal vaginal tissue. An inserter may be coupled to the pouch for facilitating insertion of the condom. The inserter may retain a distal portion of the pouch in a collapsed form. The cling mechanism may be contained within the dissolvable inserter. The inserter may be dissolvable in the presence of vaginal moisture. Methods are also provided for collapsing the pouch and compressing it into an insertion package.

  • Publication number: 20070098595
    Abstract: The invention discloses a system, method and medical device for measuring various hemoglobin derivatives, such as oxyhemoglobin, reduced hemoglobin, partial hemoglobin, carboxyhemoglobin, methemoglobin and sulfhemoglobin in whole or in hemolyzed blood. The novel method uses a statistical approach to enable the design of a portable co-oximeter. This portable co-oximeter utilizes compact light sources, such as light emitting diodes or light emitting lasers, to emit light in the visible region. Being portable, the device is a point-of-care device that can be used in emergency situations by paramedics, in the emergency room, and in a physicians office to detect and measure the concentrations and/or percentages of functional and non-functional hemoglobin derivatives in a patient's blood.

  • Patent number: 7047975
    Abstract: Employing the known “tensegrity” principle, a female condom is configured such that when the condom is inserted into a woman's vagina, the woman's introitus acts on a proximal section of an elongated pouch extending between internal and external biasing members (e.g., rings) of the condom. Inward compressive forces exerted by the introitus on the inner ring of the condom cause the inner ring to be pushed distally within the vaginal canal, and the proximal pouch section to become a tension member pulling against the external ring. This causes a “tenting” of the proximal pouch section against the introitus. The resulting interaction of compression and tensile forces (a tensegrity effect) serves to provide the condom with a high degree of internal and external stability, including resistance to twisting and slippage.

  • Publication number: 20030166990
    Abstract: Disclosed are sources and methods for delivering a radioactive dose to a site in a body lumen. The sources are preferably mounted on a balloon or other expandable or deployable mechanical structure. The source and methods enable delivery of a clinically significant dose of radiation into a vessel wall in a relatively short time while using a relatively low activity. The sources also enable delivery of a substantially uniform dose into the vessel wall, whether or not such delivery is through the wall of a stent.
