摘要： A dilation apparatus comprises an elongate member and a dilation assembly that is slidable along the elongate member. The dilation assembly comprises a platform and an inflatable dilator. The platform and the elongate member cooperate to absorb inflation forces from the dilator directed toward the longitudinal axis of the elongate member, such that the dilation forces are exerted against tissue asymmetrically relative to the longitudinal axis of the elongate member. The dilation apparatus may be used to dilate the ethmoid infundibulum in a human patient. Various devices may be used to maintain the dilated state of an ethmoid infundibulum, including a wedge, a mesh, and a tether. An illuminator may be configured to reach around an uncinate process, retract the uncinate process, and then illuminate the ethmoid infundibulum to provide improved visualization of the ethmoid infundibulum.

摘要： The embodiments herein provide an atraumatic urinary catheter. The atraumatic urinary catheter has a first tubule, a second tubule and a third tubule. The first tubule is provided with a first channel and a second channel. The first channel is wide and extended from a proximal end to a distal end of the first tubule and the first channel is open in both ends. The second tubule comprises a third channel, which is connected to a bladder cavity. The third tubule placed on the first tubule and the second tubule as a cover, to form a catheter's balloon. In order to avoid balloon explosion, the sterile water in the balloon is drained by the self-retaining mechanism of the catheter to prevent an irritation and tissue traumatization.

摘要： A stent deployment catheter having an expandable section is inserted into a patient's vasculature to position the expandable section within the diseased area. Various devices can then be quickly and easily inserted within the deployment catheter precisely positioned with respect to the diseased area, and withdrawn without traumatizing vessel tissue. Inflation of a balloon within the expandable section allows a lesion to be dilated or a stent mounted on the expandable section to be expanded and implanted in the vessel.

摘要： The invention is directed to a system for removably securing a stent which generally includes an expandable member of a catheter assembly, the expandable member having outwardly extending protrusions. An expandable stent is crimped onto the expandable member such that the protrusions extend into the gaps in the stent. The stent is secured in place on the expandable member while advancing the system through tortuous body lumen passages. The stent is implanted at the desired location in the body lumen by inflating the expandable member and thereby expanding the stent into the body lumen. The protrusions are pulled away from and out of the stent gaps by deflating the expandable member and retracting the remainder of the system.

摘要： Apparatus and methods are provided for determining the location of a prosthesis previously deployed in a body lumen, and for effecting treatment associated with the prosthesis, including a catheter having a distal end region and at least one prosthesis locator sensor disposed on the distal end region. A therapeutic device may be provided either on the distal end region of the catheter or on a separate catheter which may be positioned over the distal end region. In one embodiment the therapeutic device is a balloon catheter, while the prosthesis locator sensor is a plurality of compliant and resilient fingers projecting perpendicularly from the circumference of the catheter. The plurality of fingers detect the presence of an edge of a prosthesis by direct electrical connection, or inductance or capacitance changes. Methods of localizing prostheses with the apparatus are also provided.

摘要： A stent deployment device includes a flexible, elongate interior catheter and a retaining structure cooperating with the catheter to support a stent along a distal end support region of the catheter. The stent is supported in a reduced radius delivery state to facilitate delivery to a treatment site in a body lumen, by advancing the device over a previously positioned guidewire. An opening at the distal end of the device receives the guidewire into a guidewire lumen of the interior catheter. A second opening through the catheter wall just proximally of the support region allows passage of the guidewire to the exterior of the catheter, whereby the guidewire is contained within the device only along the distal end region. A retainer for the stent can include an exterior catheter surrounding the interior catheter and stent, and moveable axially relative to the interior catheter. A portion of the guidewire proximally of the second opening is contained between the catheters, and can be removed from the exterior catheter through a slit running axially along the exterior catheter. Alternatively, the stent retainer can include a pair of spaced apart sleeves integral with the interior catheter and frictionally retaining opposite ends of the stent, to maintain the stent in the delivery state. In this case the catheter further supports a dilatation balloon surrounded by the stent. The balloon is expanded to free the stent from the sleeves.
