摘要:
Endoscopic devices and methods used for fastening multiple tissue layers, such as, for example, an endoscopic fundoplication procedure, are disclosed. The device may include, for example, an elongated tubular member having a proximal end for extending outside of the body and a distal end for positioning proximate the multiple tissue layers, a grasper configured for positioning proximate the distal end of the tubular member and for grasping at least one of the multiple tissue layers, a device coupled to the distal end of the tubular member for folding the multiple tissue layers together, a tissue fastener configured to be inserted into the tissue layers to hold the tissue layers together, and a fastener head for inserting the tissue fastener into the tissue layers.

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.
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.

Various embodiments of a medical device having a deflecting shaft and related methods of manufacture and use are disclosed. For example, the device may include a proximal handle, a distal assembly for performing a medical procedure and a wire-coil connecting the proximal handle to the distal assembly, wherein actuation of the proximal handle may cause the distal assembly to perform the medical procedure. The wire coil may have a proximal portion comprised of a first wire and a distal portion comprised of a second wire. The second wire may have a diameter less than a diameter of the first wire so that the distal portion of the wire coil may have a flexibility greater than a flexibility of the proximal portion.

Various embodiments of a measurement device used to measure a size of a lumen and related methods of use are disclosed. For example, the device may include a proximal handle, a distal member including a radially expandable portion, a control member connecting the proximal handle to the distal member, and a measurement indication member for displaying a value indicative of a size of the expandable portion. The radially expandable portion may be configured to expand from a contracted state to an expanded state to measure the size of a lumen.
摘要:
A deflecting method and deflecting apparatus allows the distal end of device, for example an endoscopic medical device, to be remotely and adjustably deflected from a straight configuration to a deflected configuration. Manipulating a proximal handle causes the deflection, controls actuation of an end effector assembly on the distal end, and straightens the deflecting apparatus back to its original configuration.
