  • Patent number: 7361183
    Abstract: This invention relates to apparatus and methods for use in sealing a vascular puncture site and to apparatus and methods for properly locating and deploying a sealing device. The locating apparatus includes a lumen which extends from an opening in the distal region of the apparatus but located proximally of the sealing device, which lumen extends to another opening in the proximal region of the device. When the distal opening is in communication with blood in a blood vessel, blood flow through the lumen and out of the proximal opening signifies such location to the user. When the sealing device is withdrawn such that the sealing device is deployed such that it blocks the blood flow into the distal port, the user will know the location of the sealing device. In a preferred embodiment, the sealing device is then withdrawn proximally a predetermined distance to assure that no part of the sealing device extends into the blood vessel lumen. The sealing device is then detached from the delivery device.

    Abstract: This invention relates to a fertility plug, for use by both humans and animals, constructed from an impermeable polymeric film membrane covering an elastically deformable, compressible interior, which, because of pressure from the vaginal walls on the unit (forming a seal), prevents escape of semen from a vagina immediately after ejaculation or injection of semen into the vagina, but instead remain for a limited time in the vicinity of the cervix and, thus available for fertilization. A string may be attached to the unit to assist the removal of the plug after the unit has been in the vagina for a sufficient time for sperm to have entered the uterus. A nonspermicidal lubricant can be used with the fertility plug to facilitate insertion into and removal from the vagina; the nonspermicidal lubricant also enhances the seal formed between the unit's surface and the vaginal wall, further restricting the loss of semen from the vagina.

  • Patent number: 6234175
    Abstract: An ocular plug design and method of insertion is described for the treatment of dry eye. This ocular plug is a narrow rod-like cylinder of appropriate diameter, which is tapered at one end, for insertion into an ocular channel. The plug is prepared from either (or both) of two specific classes of polymeric materials having both viscous and elastic properties. The first class of polymeric materials have a glass transition temperature (Tg) at or below human body temperature (37° C.). The second class of polymeric materials have a melting temperature (Tm) at or below human body temperature (37° C.). The plug is stored in a frozen, rigid, elongated state prior to insertion into an ocular channel. Once inserted into an ocular channel, the smart plug responds to an increase in temperature, due to the surrounding physiochemical environment, whereby it becomes soft and the plug subsequently expands to adapt to the size and shape of the patient's punctum or canaliculum.
