  • Publication number: 20080249553
    Abstract: A method and device for tissue removal. The device may be used to remove uterine fibroids and other abnormal gynecological tissue. According to one embodiment, the device includes a housing, an outer tube, and an inner tube. The outer tube is fixed to the housing and includes a side window proximate to its distal end. The side window may have sloped proximal and distal ends. The inner tube has a distal end positioned within the outer tube, the distal end being adapted to rotate and, at the same time, to move back and forth past the side window, with the rotational and translational movement of the inner tube being independently controllable. The distal end of the inner tube may have an external bevel. Suction is applied to the proximal end of the inner tube to draw tissue into the side window and to remove resected tissue through the inner tube.

  • Publication number: 20080249534
    Abstract: Method and device for distending a gynecological cavity. According to one embodiment, a mechanical, non-fluid device is used to distend the gynecological cavity. Such devices include, for example, self-expanding members, such as resilient baskets, coils, whisks, prongs, and loops, or mechanically expanded members, such as inflatable balloons, mechanically-expanded cages and loops, and scissor jacks. The device may serve a purpose in addition to distension, such as illumination, imaging, irrigation, drug delivery, resection and cauterization.

  • Publication number: 20080234729
    Abstract: A suture lock fastening device to cinch a suture in a suture lock, cut the suture end, and deploy the suture lock in response to a single movement of a user. The fastening device includes a fastening head with a retainer that is configured to hold a suture lock in the fastening head. To release the suture lock from the fastening head, the retainer is irreversibly deformed. The fastening device may include an axially movable cutter with a cutting edge to sever the ends of the suture close to the suture lock. A threading device may be preloaded into the fastening device to facilitate threading the suture through the fastening device.

  • Publication number: 20080188882
    Abstract: The medical puncturing device includes a housing (12), a shield (13), and a skin puncturing assembly disposed within the housing. The shield is axially movable in the housing. The skin puncturing assembly includes a movable carrier and a skin puncturing element mounted to the carrier. A distal end of the skin puncturing element is adapted for puncturing the skin of a patient. The carrier is movable from a retracted position wherein the skin puncturing element is disposed within the shield to a puncturing position wherein the distal end of the skin puncturing element is exposed. The carrier is maintained in the retracted position by engagement of flexure members or a retaining tab with the carrier. A drive spring is provided to move the carrier from the retracted position to the puncturing position. A retraction spring is provided to return the carrier and skin puncturing element into the housing.

  • Publication number: 20080097560
    Abstract: A thermal cap that can fit a variety of head sizes is disclosed. The cap can include a shell having a fluid inlet and outlet, a sealing mechanism and removable sizing layers disposed within the shell. Depending upon the size of a patient's head, sizing layers can either be added to or removed from the outer shell to maintain a fluid circulation space between the head and the rigid shell and allow substantially even distribution of a thermal fluid about the scalp of the patient during operation. The shell is preferably rigid and an elastomeric member can seal the periphery of the cap to the patient's head to prevent leakage. Other types and aspects of thermal cap systems are also disclosed.

  • Publication number: 20070282358
    Abstract: A steerable medical instrument includes a control handle, a shaft, steering control wires, and an end effector at the distal end of the shaft. The end effector is a separate component engineered to distribute the stress and strain of bending moments along the length of the end effector to achieve predicable, repeatable, fine motion control over the distal end of the instrument. The end effector may be customized for any medical application. For example, the end effector may comprise a grasping device, a cutting devise, a snare, a specimen retrieval device, or a wound closure device (such as a stapler).

  • Patent number: 6471069
    Abstract: A device and method for separating heavier and lighter fractions of a fluid sample. The device includes a flexible collapsible inner container disposed within a substantially rigid outer container. A closure seals the open top end of the outer container. A filter assembly is sealingly mounted to the open top end of the inner container. The filter assembly includes a filter that permits lighter fractions to pass therethrough, while substantially blocking the heavier fractions. The filter assembly further includes a filter support having a slit valve registered with the filter. The slit valve opens in response to fluid pressure created by the lighter fractions for permitting the lighter fractions to flow therethrough.
