  • Patent number: 8043282
    Abstract: A Foley catheter with a retention balloon includes an elongated inflation tube so that the inflation port used to inflate and deflate the balloon may be maneuvered away from the drainage port of the Foley catheter. If the Foley catheter was placed using a urethral access sheath, the elongated inflation tube allows the surgeon to easily remove the access sheath from the patient.

  • Patent number: 7951065
    Abstract: A kit and method for supporting a pelvic floor of a person with stress urinary incontinence or other symptoms. The method involves using barbed sutures as part of a sling for supporting the pelvic floor or urethra of a person experiencing stress urinary incontinence or other symptoms. A surgeon implants the sling along with the barbed sutures, using one of several known methods. The barbed sutures may be interwoven with the sling and the supports for the sling, so that once the sling and its supports are placed into the patient, barbs of the sutures will resist movement. The sutures may also be woven into the supports to resist movement.

  • Patent number: 7766926
    Abstract: A sling for supporting a urethra in a patient has characteristics for resisting pull-out, roll-over and a combination of both pull-out and roll-over. To facilitate resistance to pull-out, sling material has protuberances or serrations to resist movement once placed in the patient by the surgeon. Improved resistance to roll-over or roll-up is achieved by providing relief on the sling in areas potentially subjected to roll-over forces by endopelvic fascia. The sling may be used on female or male patients, and may be used in conjunction with a wider support portion to support a bladder and a urethra, rather than a urethra alone. The sling may also be used to support other tissues within a patient.

  • Patent number: 7731722
    Abstract: A retrieval device for use in renal, biliary, vascular or other systems of a body includes a collapsible basket in a narrow sheath. A surgeon advances the device beyond an object to be removed from a body, such as a kidneystone, a gallstone, or a thrombus. The surgeon then retracts the sheath or advances the basket from the sheath. The basket deploys only to one side of the sheath. In some embodiments, the periphery of the basket has a flex point to enable the basket to easily collapse into the sheath. If the sheath is adjacent a body vessel, such as a blood vessel or a ureter, the sheath remains adjacent the wall, while the device deploys in such a manner as to seal against the walls of the vessel and block the flow of fragments, emboli, thrombi, or other undesirable objects.

  • Publication number: 20080091058
    Abstract: Instruments for implanting a urethral sling in female patients, and a better technique for implanting the sling, are disclosed. Porcine small intestine submucosa is processed into a sturdy yet assimilable sling for supporting a urethra of a female patient. The sling is implanted using ligature carriers and sheaths to minimize contact between the sling and the vaginal and abdominal tissues of the patient. The ligature carriers are implanted into the patient via a suprapubic or vaginal route (antegrade or retrograde). The sling is then attached to the ligature carriers and is drawn into the patient through the sheaths. Then sheaths are then removed and the sling is adjusted and trimmed.

  • Patent number: 6764499
    Abstract: A replaceable handle for side loading the proximal end of a medical device therein, which is typically inserted with the operating lumen of an endoscope. The replaceable handle can side-load the proximal end of the device into the handle for added manipulation of the distal end such as in removing a stone from the kidney or ureter leading therefrom. An inner housing is rotatable within an outer housing of the handle to secure the medical device in the housing passageway, and is spring biased to then move proximally with respect to the outer housing, moving the inner control rod of the medical device proximally to withdraw the stone basket mostly into the outer cannula and capture the stone for removal from the patient. A push button in the proximal end portion of the inner housing is depressible to permit insertion or withdrawal of the proximal end of the inner control rod of the stone retriever within the inner housing, and is releasable to secure the inner control rod in the handle.

  • Patent number: 6482178
    Abstract: A localization device (10) comprising an outer needle cannula (11), an optional inner sleeve cannula (13) and an anchor stylet comprising a plurality of preformed superelastic alloy wires (12). Once the distal portions (14) of the wires (12) are deployed from the ends of the sleeve and needle cannulae, they function as curved barbs (15) projecting outward to anchor the device into tissue, an organ, or a foreign body. A slidable locking member (18), such as a pin vise, can be included over the outer needle cannula for securing the localization device against a template.

  • Patent number: 6210315
    Abstract: A brachytherapy device 10 for exposing to radioactivity a patient includes an elongate member such as a needle or cannula 12 adapted for introduction into the patient and also includes a stylet 14 slideably receivable in a longitudinal throughbore 16 in the needle 12. The device 10 also includes a portion 64 near either the proximal end 18 of the needle 12 or the distal end 24 of the stylet 14 which provides a local, defined amount of friction between the needle 12 and the stylet 14. The device 10 further includes an anti-static handle 34 connected to the needle 12. The handle 34 has an interior ramp surface 40 in communication with the throughbore 16 of the needle 12, frustoconical in shape and possessing an included apical angle of at least about 16°. The localized friction portion 64 can be a crimp or flange 48 on the stylet 14, or a crimp 44 or deformation 46 in or of the needle 12.

  • Patent number: 6053934
    Abstract: A replaceable handle (10) for side loading the proximal end of a medical device (41) therein, which is typically inserted with the operating lumen of an endoscope. The replaceable handle is easily removed from the proximal end of the medical device for removing an endoscope over the medical device. with the endoscope removed, the replaceable handle can side-load the proximal end of the device for added manipulation of the distal end such as in removing a stone from the kidney or ureter leading therefrom. the replaceable handle includes an outer elongated housing (11) with passage (13) extending longitudinally therein with external communication (14) therealong. The outer housing also includes a first attachment mechanism (15) disposed about the distal end for receipt of a first medical device member therein. The handle also includes an inner elongated member (17) positioned in the housing passage and extending proximally therefrom.
