  • Publication number: 20160135984
    Abstract: An occlusive device can reversibly block flow through a lumen of a patient, such as a blood vessel, a reproductive structure, a ureter, a colon, and other body lumens. The device can include a frame comprising having a distal portion that tapers inwardly toward a central axis of the frame. The frame can expand from a compressed configuration to a deployed configuration. The device can also include a flow reducing member coupled to the frame for restricting flow through the lumen and a withdrawal component that can engaged by a retrieval device to retrieve the device from within the lumen.

  • Patent number: 9247942
    Abstract: Described are apparatus and methods for preventing sperm passage through a reproductive structure of a patient, and also for subsequently reversing the preventative measure in order to restore fertility to the patient. In some embodiments, the apparatus includes an elongate member arranged to form a frame having a distal and proximal opening and configured to be positioned within a lumen of the reproductive structure. The apparatus may also have a flow reducing member coupled to the frame such that when the frame is positioned within the lumen, the flow reducing member substantially impedes, reduces, or totally obstructs passage of sperm through the lumen.

  • Publication number: 20160022293
    Abstract: A vessel-occluding medical device for the use in diagnosis and/or treatment of cardiovascular disease in the human body includes an outer tube, an inner tube slidably housed within the outer tube, and a tubular sleeve comprising a generally U-shaped, direction reversing region, which moves along the length of the tubular sleeve, to assume radially contracted and radially expanded state as the inner and outer tubes move between the first and second positions. When the tubular sleeve is in the radially expanded state, the inner portion of the tubular sleeve has a funnel-shaped surface and a longitudinally-extending opening to permit material to pass therethrough for receipt of material into the inner tube.

  • Patent number: 8352014
    Abstract: A site marker is provided that includes a generally hollow body defining a cavity. A deployment line within the site marker positions at least one marker element within the body portion. The deployment line has a first end that is fixedly secured to a first end of the body portion and a second end that is secured to a second end of the body portion. The deployment line is pre-biased so as to pull the first end of the body portion towards the second end of the body portion, and thereby expand the body portion.

  • Patent number: 8287566
    Abstract: Some embodiments of a spray device can be configured to maintain a viscous fluid in isolation from a propellant fluid until after the viscous fluid exits from a nozzle of the spray device. For example, the viscous fluid may include an adhesive such as surgical adhesive. When the spray device is actuated, the surgical adhesive can exit the nozzle so that the propellant fluid acts upon the surgical adhesive to break it into droplets for application on a targeted site.

  • Publication number: 20120234434
    Abstract: This invention provides a pressure sensing catheter, and method for using the same, which eliminates the practitioners' need to fill the catheter with fluid manually prior to insertion, and thereby increases the accuracy and ease of the overall pressure-sensing procedure. The illustrative catheter includes, in its proximal end, a transducer base or housing that is permanently attached to the catheter shaft. The base includes, inserted thereinto, one or more miniaturized pressure transducer assemblies, which are in fluid communication with corresponding pressure lumens that extend down the shaft and are in communication with one or more predetermined balloons by discrete channels or ports, which provide a fluid passage between the interior space of the balloon and the corresponding pressure lumen. The integral assembly includes a predetermined, previously installed charge of fluid that extends from the transducer, through the corresponding pressure lumen and into the interior volume of the sensing balloon.
