    摘要: A surgical device is provided for forming a channel through or partially through vascular tissue, including vascular tissue, utilizing both mechanical and laser energy, and, if desired, depositing a therapeutic agent therein. The device includes an optical fiber for transmission of laser energy, a housing, and a hollow guide attached to the housing through which the optical fiber extends. A needle is attached to the distal end of the optical fiber in fluid communication with a catheter surrounding the optical fiber. Additionally, an actuator is included operably connected to the optical fiber for selectively extending the needle and/or fiber from the hollow guide. Finally, a laser control device is contemplated operably connected to the optical fiber, transmitting laser energy from the distal end of the fiber after the needle has penetrated a layer of selected distance into the tissue.

    摘要: A conforming valved cervical cap assembly is provided with an elastomeric inner layer molded and cured in situ adjacent the exocervical surface of a cervix uteri. The inner layer is wettable, non-porous and matingly fits and resiliently complements the exocervical surface. In order to prevent the molding material from clogging or otherwise impairing operation of the valve, a valve cover is detachably connected to the valve during molding and curing.

    摘要: A non-invasive birth control device in the form of a custom-formed, valved cervical cap is disclosed. The cervical cap comprises a cup-shaped elastomeric shell substantially complementary with contiguous surface of portio vaginalis cervicis when in contact therewith, having an aperture at the apex of the shell, and a depending skirt that is thinner than said shell and is provided with a plurality of spaced slits. The aperture is covered by an elastomeric web secured to the shell and defines, together with the shell, a one-way valve means having a discharge port offset from the aperture. The cervical cap can be fabricated from a specially designed blank of a thermoplastic elastomeric material using a replica of cervix uteri as a mold.

    摘要: A prefabricated cervical cap includes a generally dome-like flexible shell of a depth sufficient to receive therein a major portion but not all of cervix uteri and a resilient, form-assuming internal liner for the shell. The liner is integral with the shell and is deformable upon contact with cervix uteri without substantial deformation of a contiguous portion of the cervix uteri. The liner may extend beyond the shell. In a preferred embodiment the cervical cap includes a one-way valve means that accomodates the flow of a uterine discharge without need to remove the cap.

    摘要: A method for treating patients suffering from left ventricular dysfunction is disclosed. The method involves applying, during diastole, for a time period of about one hour, at least five days each week for at least about six weeks, an incrementally increasing external therapeutic pressure sequentially to the patients' lower extremities from first the calves, then the thighs and last the buttocks. The initial hourly treatments are carried out at a peak diastolic/systolic pressure ratio (D/S Ratio) in the range of about 0.4:1 up to about 0.9:1, depending on the patient's left ventricular ejection fraction. The D/S Ratio is increased slightly during the next set of hourly treatments, the D/S Ratio is again increased slightly during the next following set of hourly treatments, the D/S Ratio is again increased slightly during the next set of hourly treatments, and finally the D/S Ratio is increased slightly and maintained during the remaining set of hourly treatments. The patient's cardiopulmonary functions preferably are monitored to determine if additional external therapeutic pressure treatments are needed.

    摘要: The present invention is embodied in a medical device which is comprised of a thermal energy delivery component, for example, including an elongate optical fiber terminating in a lateral laser energy emitter, and an outer coolant component, which includes a cannula for receiving the thermal energy delivery component, which terminates in an energy-transmissive balloon for surrounding the thermal energy emitter and providing a tissue-contacting coolant chamber. The cannula portion of the coolant component is moveably sealed around the laser energy delivery component. In one embodiment, a retaining means prevents the thermal energy delivery component from being detached from the coolant component. In an alternate embodiment, there is no retaining means, allowing the more costly thermal energy delivery component to be removed, sterilized and later reused, whereas the less costly outer coolant component, which contacts tissue, blood and body liquids, can be discarded after use.

    摘要: A laser energy delivery device is provided that is suitable for irradiating a body tissue with relatively long wavelength laser energy in the presence of an aqueous liquid without significant absorption of the laser energy by the liquid. The device includes an elongate hollow sheath that has an open aperture at its distal end portion and closed at its proximal end, a laser energy conduit such as an optical fiber or hollow wave guide, within the sheath, the distal end of the conduit being disposed near the open aperture at the distal end portion of the sheath, and the proximal end of the conduit being adapted for connection to a source of long wavelength laser energy. The sheath also includes an inlet port, spaced from the proximal end of the sheath, and adapted to receive and deliver a biologically compatible gas through the sheath to a body tissue site in contact with the open distal end of the sheath. In use, the open aperture at the distal end portion of the sheath is positioned in contact with a body tissue site. Gas, such as carbon dioxide, infused through the sheath displaces an aqueous liquid from the region between the distal end portion of the sheath and the tissue. Laser energy emitted from the distal end portion of the conduit passes through the substantially liquid-free region at the distal end of the sheath and impinges on the tissue to be irradiated. The laser energy can be used to ablate, vaporize, coagulate or shrink tissue at the target zone without interference from aqueous liquids, which tend to absorb relatively large amounts of long wavelength laser energy and reduce the efficiency of tissue ablation.
