Abstract:
Apparatuses of the type broadly applicable to numerous medical applications in which it is desirable to insert one or more steerable or non-steerable catheters or similar devices into a working channel of an associated device, such as an endoscope, catheter, etc., or passageway of a patient, are disclosed. The apparatuses may include catheters having a dedicated guide wire channel and one or more of the following: viewing capabilities, a working channel, and auxiliary channels, such as insufflation/irrigation channels. The catheters may include a guide wire channel that is configured to provide the catheter or other device with rapid exchange capabilities.
Abstract:
A medical device may include an elongate member including a proximal end and a distal end. The medical device may also include a rotatable member at the distal end of the elongate member. The rotatable member may be rotatably coupled to the distal end of the elongate member. The rotatable member may include a longitudinal axis, and may be configured to rotate about the longitudinal axis. The rotatable member may also include a gripping element configured to engage a layer of tissue. The gripping element may be configured to selectively couple at least a portion of the layer of tissue to a surface of the rotatable member, to restrict relative movement between the portion of the layer of tissue and the surface of the rotatable member, during rotation of the rotatable member.
Abstract:
Various apparatuses to attach a first medical device to a second medical device are described that allow the physician to grasp only a single device while the other device remains securely attached to the one being grasped. The apparatuses, once they are attached to the first medical device, are designed to be easily and quickly attached and detached to a second medical device, normally only requiring the use of one hand. Furthermore, the apparatuses oftentimes include a base that can easily couple and decouple from the portion that is attached to the second medical device so that if the need arises to separately use the second medical device, it can be decoupled from the first medical device without completely removing the apparatus from the second medical device.
Abstract:
A device for treating tissue includes a capsule extending longitudinally from a proximal end to a distal end and including a lumen extending therein and a clip slidably received within the lumen of the capsule. The clip includes a middle prong, a first outer prong and a second outer prong. The first prong is coupled to the middle prong so that the first prong is movable relative to the middle prong between a first open configuration and a first closed configuration. The second outer prong coupled to the middle prong so that the second prong is movable relative to the middle prong between a second open configuration and a second closed configuration. The first and second outer prongs are independently movable relative to the middle prong to be moved between the first and second open configurations to the first and second open configurations and the first and second closed configurations.
Abstract:
This disclosure provides design, material, manufacturing method, and use alternatives for medical devices. An example medical device may include a medical device for delivery of a surgical closure member. The medical device includes an elongate tubular member having a proximal end, a distal end and a lumen extending therein. The elongate tubular member is adapted to be delivered through the working channel of an endoscope and the lumen is adapted to receive a surgical closure member. The medical device also includes a tissue support extending from the distal end of the elongate tubular member. The tissue support includes a support surface and the support surface is adapted to support tissue as a surgical closure member engages the tissue thereon.
Abstract:
Several embodiments of the present invention are generally directed to medical visualization systems that comprise combinations of disposable and reusable components, such as catheters, functional handles, hubs, optical devices, etc. Other embodiments of the present invention are generally directed to features and aspects of an in-vivo visualization system that comprises an endoscope having a working channel through which a catheter having viewing capabilities is routed. the catheter may obtain viewing capabilities by being constructed as a vision catheter or by having a fiberscope or other viewing device selectively routed through one of its channels. The catheter is preferably of the steerable type so that the distal end of the catheter may be steered from its proximal end as it is advanced with the body. A suitable use for the in-vivo visualization system includes but is not limited to diagnosis and/or treatment of the duodenum, and particularly the biliary tree.
Abstract:
A fixation assembly and associated methods for making and using the assembly. The assembly includes a hub assembly having a needle hub secured to a needle and a stylet hub secured to a stylet extending through a lumen of the needle. The stylet hub is selectively actuatable relative to the needle hub between a first position and a second position. A stop is removably coupled to the hub assembly when the stylet hub is in the first position to prevent actuation of the stylet hub to the second position. The stop is removed from the hub assembly to allow actuation of the stylet hub to the second position.
