摘要： An apparatus and method for ejecting fluid from a fluid delivery system. The fluid delivery system has a pneumatic assembly that when triggered injects gas into a hydraulic assembly, which in turn ejects fluid through an external interface. An electronic interface displays various measurements, for example, how much fluid has been ejected and if the hydraulic system is closed the pressure of the system. The pneumatic assembly can also be depressurized such that fluid can reenter the hydraulic assembly through the external interface.

摘要： A breakaway valve body for a peel-away introducer sheath. The valve body can be used in conjunction with a distally coupled peel-away introducer sheath and a proximally coupled flexible valve sleeve for restricting fluid flow from the introducer sheath when the valve body compresses the valve sleeve to a closed position. The valve can include a body scored or weakened to break along a predefined path in response to applied force. The valve preferably includes a first member and a second member movable relative to each other and having a pinch member therebetween for constricting a flexible valve sleeve placed between the first and second members. In one valve, the first and second members are pivotally disposed on hinges to allow the members to open and close about an inserted flexible valve sleeve and to pinch the sleeve with a pinch member. The valve preferably includes a proximal region of valve sleeve extending proximally past the valve pinch member to allow insertion of a catheter distal end into the valve sleeve proximal end while the more distal valve sleeve region is constricted in a closed position. The valve allows insertion of a catheter into the introducer sheath with minimal blood loss. The valve allows easy removal of the sheath from an inserted catheter by snapping the valve and pulling the halves apart, thereby tearing the peel-away sheath away from the catheter.

摘要： The present invention relates to methodology of and apparatus for accurately positioning devices for performing endoscopic cannulation, papillotomy and sphincterotomy and similar procedures. The sphincterotome with a steerable or adjustable distal segment of the present invention allows the physician to control the position of the distal tip of the device independently of the endoscope and adjust for inconsistencies in the device and the anatomy. According to one embodiment of the present invention, a threaded portion of a cable assembly cooperates with a torque transmission element and a cog to enable the operator to rotate a cutting wire into a desired position relative to the catheter. Alternate embodiments allow the operator to fix the depth of a needle knife while allowing, if desired, accurate rotational positioning of the associated catheter. Threaded stabilizing elements, pivot elements and a steering wire may be used together or individually to accomplish these features. Presently available products that may be modified according to the present invention include, but are not limited to, Boston Scientific Sphincterotomes and Needle Knives.

摘要： Various embodiments of bulking or cushioning agents or material and related medical devices and methods are disclosed. For example, a method of performing a medical procedure in a tract of a body may include injecting a material in a liquid phase proximate a target site between a first tissue layer and a second tissue layer, allowing the material to transition from the liquid phase to the gel phase in response to a raise in temperature of the material to approximately at or above the predetermined temperature, and performing a surgical procedure on the target site. The material may have the liquid phase at temperatures below a predetermined temperature and a gel phase at temperatures approximately at or above the predetermined temperature.

摘要： A steerable endoscopic sheath has a proximal end, a distal end and a working channel lumen disposed therein. A plurality of solid state light emitting devices such as light emitting diodes are positioned near the distal end of the sheath and are selectively energized to illuminate internal body tissues. An imaging device such as a photo diode or CCD array creates an image from light reflected from the tissue. The distal tip of the endoscopic sheath is selectively moveable with a deflection device that is insertable into the sheath. The deflection device includes a tip deflection mechanism that allows a user to move the tip of the deflection device. With the deflection device inserted in the sheath, movement of the distal tip causes a corresponding movement in the distal tip of the sheath. The distal tip of the sheath has a shape retaining mechanism that allows it to retain the shape imparted by the deflection device once the deflection device is removed from the sheath.

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： 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.
