摘要: A delivery catheter for a radially compressible tubular prosthesis comprises an elongate shaft slidably received within an elongate sheath. The prosthesis is carried over the distal end of the shaft where it is contained in a radially compressed configuration by the sheath. After introducing the catheter to a desired target location within a body lumen, the prosthesis may be released by proximally retracting the sheath. The prosthesis will remain anchored to the shaft during at least part of the release procedure, permitting the user to recapture the prosthesis by distally advancing the sheath.

摘要: The present invention provides devices and methods to promote the compression and/or recapture of endoluminal prostheses. An endoluminal prosthesis system generally comprises a tubular body and a radially compressible endoluminal prosthesis. The tubular body includes a lumen, while the prosthesis has a proximal end with a plurality of engageable structures radially disbursed thereabout. Each of a plurality of filaments extends distally from the lumen of the tubular body to an engageable structure so that tensioning of the filaments radially compresses the proximal end of the prosthesis. Preferably, a sheath then slides over the prosthesis, the sheath ideally having a plurality of axially oriented runners which form a radially flared structure to smoothly compress the prosthesis therebetween.

摘要: A device for controlling urinary incontinence in a human female, comprising a resilient pad, configured to seal against and occlude the urethral meatus of the user. The pad includes a base that is adapted to seat against the vestibule of the user's vulva, anteriorly of the vaginal orifice, thereby covering the urethral meatus. An adhesive is provided on the base to seal against and occlude the urethral meatus, and to retain the pad in place against the vestibule. The pad has lateral edges that fit inside the labia minora of the user, to aid in retention of the device. The surface of the pad opposite the base is formed into a longitudinal stiffening ridge that extends into the interlabial space. A handle is attached to the ridge to facilitate removal.

摘要: Disclosed is an apparatus and method for the treatment of the symptoms of obstructive prostatism. The apparatus comprises an expandable dilation catheter and preferably an axially elongate sheath, adapted for transurethral insertion via the external opening of the urethra. The sheath is ellipsoid in cross-section, and provides an initial path through which the catheter and a standard cystoscope lens is guided. The dilation catheter or the sheath are provided with a non-radiological locating means for positioning the dilation portion of the catheter with respect to an anatomical landmark. Once the catheter has been properly positioned with respect to both the bladder neck and the sphincter, the dilation balloon may be inflated to force open the affected prostatic urethra and eliminate the obstruction.

摘要: Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The sheath is configured for use in the vascular system and has utility in the introduction and removal of balloon counterpulsation catheters. The access route is through the femoral arteries and the iliac arteries into the aorta, where an intra-aortic balloon pump catheter is positioned to provide cardiac support. The distal end of the sheath is maintained in the first, low cross-sectional configuration during advancement to the arteries into the aorta. The distal end of the sheath is subsequently expanded using a radial dilatation device.

摘要: Devices and methods are disclosed for achieving hemostasis in traumatized patients. Such haemostatic packing devices and methods are especially useful in the emergency, trauma surgery or military setting. The patient may have received trauma to abdominal viscera, the thoracic cavity or the periphery. The devices utilize fluid impermeable outer surfaces and distributed pressure to achieve tamponade and hemostasis, primarily by exertion of pressure. The devices come in a variety of configurations including sheet, rolled sheet, folded sheet and polygonal solids including extruded shapes. The devices are capable of serving as carriers for thrombogenic or anti-pathogenic agents. The devices are flexible, bendable, and conformable in their wet or dry state so that they exert distributed pressure on the wound. The hemostatic packing devices may be placed and removed by open surgery or laparoscopic access without generating excessive re-bleeding, and may further comprise antimicrobial or thrombogenic regions.

摘要: Surgical bolts are useful for solid visceral wound hemostasis. The devices utilize flexible, variable depth transfixing bolts that penetrate the viscera. These bolts bring the tissue into apposition and hold said tissue in apposition while the wound heals. These bolts, or soft tissue rivets, overcome the limitations of sutures that are currently used for the same purposes. The devices are flexible, bendable, and conformable in their wet or dry state. The bolts include pressure plates that are capable of exerting compressive pressure over broad areas of visceral wounds without causing tearing of the friable parenchyma. The bolts are placed and removed by open surgery or laparoscopic access. The bolts can be placed into tissue where both sides of the bolt are exposed, or they can be placed blindly into tissue where the bolt does not protrude out of the tissue at its distal end.

摘要: A system is disclosed for removing gas bubbles from blood during circulatory assist procedures. Such bubbles are generated, along with particulate matter, in an extracorporeal circulatory bypass system by the pump, oxygenator and other components. Current filters are inefficient at removing small bubbles that can cause neurological defects and renal and other organ failures in the patient. An active filter apparatus and method is disclosed that forces the bubbles to the center of the system where they are removed from the blood before the blood exits the filter. The filter comprises an axially elongate cylindrical shell with a blood inlet, a blood outlet and a gas outlet. A motor driven impeller spins the blood within the shell and forces the gas toward the center by centripetal force, utilizing the buoyancy effects of the bubbles in blood, whereby the bubbles can be bled off at the center of the filter.
