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： A medical instrument converts linear movement of a shaft at a proximal end of the instrument to a rotational movement of an end effector of the instrument. According to one embodiment, the medical instrument includes an end effector formed of a snare loop connected to a shaft that is located within a sleeve. Once the sleeve is located near a desired location within a patient, the snare loop may be rotationally positioned with linear movement of the shaft by the operator. The shaft is formed with a threaded portion that matches threads formed in a torque transmitter element fixed within the sleeve. Linear movement of the shaft through the torque transmitter element causes the shaft to rotate. The medical instrument may also include a pivot connector for reducing torque build-up of the shaft and/or a clutch assembly for restricting controlled rotation of the snare loop to only one direction.

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： 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： An intravascular catheter that exhibits the combined features of superior flexibility, softness, radiopacity and oval/kink resistance. The catheter includes an elongate shaft having a proximal region, a distal region and a lumen extending therethrough. The proximal region of the shaft includes an inner lubricious polymer layer, a reinforcement layer and an outer layer. The reinforcement layer comprises a braid having one or more metallic members and a plurality of polymer members wherein each polymer member comprises a plurality of monofilaments, preferably formed of LCP. The polymer members of the braid provide improved flexibility and softness in addition to high burst pressure. The metallic member(s) of the braid provide improved radiopacity and oval/kink resistance. The catheter may also include a longitudinal member extending along the reinforcement layer.
