摘要： An apparatus and method for access to the inside of a body includes a transparent sheath with a radiopaque marking and fastener for securing a guidewire or catheter. The transparent sheath permits objects located within and near the sheath to be visualized with an external imaging system. Objects located near the sheath can also be observed with an imaging device disposed inside the sheath. The radiopaque marker permits accurate positioning of the sheath in the body. The sheath can be inserted into the body over an interventional device. A fastener prevents migration of a guidewire or catheter during the procedure.

摘要： A catheter with a small optical fiber or bundle of fibers includes a scanning mechanism constructed with the use of any vibration capable component. Magnetic, piezoelectric or other mechanisms are used to vibrate the end of the fiber and thus create a scanning effect which extends the field of view. One or more lenses may be utilized, including a lens attached to the distal tip of the image fiber, or a lens attached to the distal tip of the catheter for creating an image plane which can be scanned by the fiber. In one embodiment, multiple light sources may be connected to the fiber for enabling the use of field sequential color techniques for real-time imaging, as well as real-time fluorescent imaging for disease detection. A photodetector assembly connected to the proximal end may contain both filtered and unfiltered detectors for use with both standard imaging and fluorescent imaging. The resulting vision catheter is relatively inexpensive and disposable.

摘要： A step up transformer has an inert core, primary windings concentrically surrounding the inert core, and secondary windings concentrically surrounding the primary windings, the ratio of secondary windings to primary windings of up to 1,000,000:1. The step-up transformer is particularly useful in an x-ray catheter having an x-ray source in a vacuum tube and a power source. The power source can deliver a lower voltage which is stepped up at by the transformer to produce a voltage sufficient to stimulate production of x-rays by the x-ray emitter source. Methods for preparing the step-up transformer and x-ray catheter and methods of administering x-rays to subjects with the x-ray catheter of the invention are also disclosed.

摘要： A system for treating an aneurysm in a vessel includes a delivery device having a delivery portion suitable for delivery of embolic material. The delivery device is placed in a neck of the aneurysm and an expandable member is placed proximate the neck. The expandable member is expanded to overlie substantially the entire neck. Embolic material is delivered to the aneurysm with a delivery device. The expandable member is held over the neck to inhibit movement of the embolic material out of the aneurysm. Blood is allowed to flow out of the aneurysm, past the neck of the aneurysm, and through the vessel while the expandable member is held over the neck of the aneurysm.

摘要： A prosthesis delivery system having a balloon catheter with an inflatable balloon on its exterior. The balloon is inflatable by injection of fluid through a lumen in the catheter and the balloon is initially partially constrained against inflation by a constraint. A tubular prosthesis is disposed on the catheter over at least a portion of the balloon and a portion of the constraint. The tubular prosthesis has a contracted condition and an expanded condition. The tubular prosthesis is initially disposed on the catheter in the contracted condition. Further, a balloon catheter includes a constraint so that the balloon may be sequentially inflated for dilatation purposes such as in a valvuloplasty operation.

摘要： The invention features a catheter having a catheter body of extended length for insertion within a body of a living being. The catheter also includes an ultrasound imaging device disposed within a distal portion of the catheter body. The ultrasound imaging device generates electrical signals used by an ultrasound imaging system to display a real-time image of tissue surrounding the distal portion of the catheter. The catheter further includes a cutting element, e.g., an electrode wire or a laser fiber, having a proximal portion disposed within the catheter body. The catheter also includes a mechanism connected to the catheter body that causes the distal portion of the cutting element to extend from the catheter body. The distal portion of the cutting element generates energy in tissue with which it is brought in proximity to form a cut in the tissue. The ultrasound imaging device is positioned relative to the cutting element such that the real-time image produced by the ultrasound imaging system can include the cutting element in relation to the tissue.

摘要： A method and apparatus for managing polyps by which an elongated tubular member generally positionable within the working channel of an endoscopic device. The tubular member carries a selectively extendable severing device and capturing device at its distal end. Control apparatus at the proximal end of the tubular member enables a physician to extend and retract the severing and capturing devices. The physician retracts the capturing device to grasp the portion of the polyp to be severed and retracts the severing device to sever the polyp. The capturing device retains the severed portion of the polyp for removal with the tubular member. In one embodiment the capturing device includes an injection needle.

摘要： A slip-layered balloon catheter for insertion into a bodily conduit, especially an artery. The catheter comprises a shaft (21) having at least one lumen (26) for delivery of a fluid inflation media and a slip-layered balloon (12) made up of a plurality of layers with a low-friction substance between the layers. The low-friction substance causes the layers to slide readily relative to one another, softening the balloon while maintaining its strength. Optionally, the balloon includes a plurality of slip-layered segments radially disposed about the balloon wall, and separated by lengthwise ridges joining the layers of each segment together. Also optionally, an elastic sleeve surrounds the balloon wall to improve refoldability of the balloon.

摘要： A biopsy needle instrument for capturing a plurality of sequentially biopsied, discrete specimens. The instrument includes a housing, an axially elongated stylet and a cannula coaxially disposed about the stylet. The stylet and cannula have distal and proximal ends and extend from the housing. The stylet and cannula can move relative to each other and to the housing between retracted and extended positions. The stylet includes a side-facing notch adjacent the distal end of the stylet having an axial length that is greater than a predetermined specimen length. Portions of the cannula adjacent the distal end overlie the side-facing notch when the cannula and stylet are both retracted. When the stylet is extended and the cannula is retracted, a distal portion of the notch having length corresponding to the predetermined specimen length is disposed for facilitating the prolapse of tissue into the notch.
