  • Patent number: 8480559
    Abstract: A urethral support system is described, including an introducer device and tissue implant. The introducer device may include a needle with multiple curves, some of the curves having multiple radii. A sheath assembly may be utilized to assist the passing of the tissue implant through a patient's tissue. The sheath assembly may include connectors configured to connect the sheath assembly to an end of the needle and a tab configured to detachably couple sheath sides over the tissue implant.

  • Publication number: 20110144485
    Abstract: A surgical method, including inserting an internal viewing device via a ureter into a first calyx of a kidney, inspecting the first calyx with the internal viewing device, and determining whether the first calyx contains one or more stones. If the first calyx does contain one or more stones, it is marked with a first marking material, but if the first calyx does not contain one or more stones, it is marked with a second marking material different from the first marking material.

  • Patent number: 7654989
    Abstract: A ureteral access sheath comprises a sheath assembly having a main lumen and one or more secondary lumens. The sheath assembly can be configured with medical devices in both lumens, for example, a ureteroscope in the main working channel, and a guidewire, stone basket, grasper, laser fiber, or other surgical instrument in the secondary working channel. Or the sheath assembly can be configured with a medical device in one channel and the other lumen coupled to an irrigation means, such that irrigation of the surgical field can be efficiently accomplished even though the main working channel is substantially completely occupied by, e.g., a ureteroscope. Or the sheath assembly can be configured for irrigation through one lumen and aspiration through the other lumen, thereby creating a turbulent flow which washes the surgical field to facilitate removal of particles and debris.

  • Publication number: 20030092968
    Abstract: The present invention relates to a stabilizer that immobilizes tissue at a surgical site. A preferred embodiment of this device is used during cardiac bypass surgery and includes a preferably rectangular, oblong or similar shaped device having a width dimension that is greater than the lengthwise dimension such that an aperture area is formed along three sides of the surgical site so that a graft or anastomosis that is formed in the aperture area allows the stabilizer to be removed without disturbing the graft and the device may be used in combination with flexible tapes or threads to apply an upwardly directed force to the tissue adjacent to the surgical site.
