摘要： A low profile emboli capture device is provided for use in angioplasty and other intravascular procedures. A standard guidewire is utilized having a reduced cross-sectional area formed near its distal end. A filter and self-expanding stent are packaged on the reduced cross-sectional area of the guidewire. A movable sleeve extends over the guidewire and holds the self-expanding stent and filter in their retracted positions while the device is being positioned in the artery. The sheath is moved relative to the self-expanding stent and filter, whereupon the self-expanding stent and filter become deployed.

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 drainage catheter includes a shaft having a flexible distal portion to be anchored in a cavity of a patient and a proximal portion attached to a hub. The hub includes a side port with a deformable sealing insert having self-sealing passageways for tensioning members, such as nylon filaments, passing through the catheter shaft and exiting the side port. The tensioning members are pulled proximally to deform and thereby anchor the distal portion of the catheter. Excess filament length is wrapped around a resilient pinch washer and held inside a groove in the pinch washer, with the groove thereafter compressed by a C-clip to secure the excess filament length inside the groove.

摘要： According to the present state of the art, endoscopic cannulation of the common bile duct and papillotomy and/or sphincterotomy of the Papilla of Vater and/or the Sphincter of Oddi is accomplished by advancing a sphincterotome (or papillotome or cannulotome) into an endoscope/duodenoscope so that the distal tip of the sphincterotome exits the endoscope adjacent the sphincter muscles at the Papilla of Vater. The endoscope mechanisms are then manipulated to orient the distal tip of the sphincterotome to the desired position for proper cannulation of the duct. Accurate and consistent control of the length of the exposed blade is made difficult due to a number of factors. These factors include: 1) differences in the inside diameters of the outer tube and the needle knife wire, 2) the orientation of the needle knife wire within the outer tube, 3) the mismatch of tolerance of the needle knife wire and the inside diameter of the extrusion, 4) anatomy, and 5) endoscope manipulation. A sphincterotome incorporating the present invention will provide the user with an indication of the exposed blade length and will allow the physician to control the length of the exposed blade. According to one embodiment of the present invention, various visual indications are presented to the user as the needle knife is advanced from its outer sheath. These visual indications, combined with a mechanical method to hold the knife in position during catheter placement allows the user to perform precise incisions. 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： 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 securement location on a polymer thread structure includes the tying of a knot. In order to secure the knot, the knot is ultrasonically welded. Multifilament suture knots may be welded. The ultrasonic welding technique also tends to decrease the diameter of the knot from its pre-fused diameter. The resultant fused knot exhibits increased tensile and peel strength.

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.
