Abstract:
A medical device includes an outer polymeric tubular member and an inner tubular member. The outer polymeric tubular member includes one or more cuts formed therein to increase flexibility of the outer polymeric tubular member and includes an inner surface. The inner tubular member extends through the outer polymeric tubular member and has an outer surface in slidable contact with the inner surface of the outer polymeric tubular member. The outer polymeric tubular member is able to move relative to the inner tubular member as the medical device bends. In an example, the outer tubular member may be formed of a heat shrink material.
Abstract:
The present disclosure relates to the field of endoscopy. Specifically, the present disclosure relates to systems and methods for delivering a therapeutic agent within a body lumen, and maintaining the therapeutic agent in contact with a wall of the body lumen for a beneficial period of time. In particular, the present disclosure relates to systems and methods to prevent lesions within the gastrointestinal tract from spreading into healthy surrounding tissue.
Abstract:
This disclosure provides design, material, manufacturing method, and use alternatives for medical devices. An example medical device includes a scaffold including a central member and a plurality of extension members extending away from the central member. The central member includes a plurality of discrete attachment locations corresponding to each of the plurality of extension members and each of the plurality of extension members is pivotably coupled to the central member at a corresponding discrete attachment location. The medical device also includes a covering substantially surrounding the scaffold and an electrode located at a distal end of each of the plurality of extension members. Each electrode extends through at least a portion of the covering.
Abstract:
A device for implanting in a gastrointestinal system of a patient may include an elongate flow modulator configured to be inserted in an intestine, wherein the flow modulator defines an enclosed interior space to hold a fill material.

Abstract:
Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a guidewire. The guidewire may include a core wire having a body region and a distal tip region. A distal tip member may be disposed along the distal tip region. The distal tip member may have a proximal end. A sleeve may be disposed along the body region. The sleeve may be disposed adjacent to the proximal end of the distal tip member and extending proximally therefrom. The sleeve may include a first member and a heat shrink member. The first member may have an uneven outer surface.

Abstract:
The disclosure relates generally to the field of medical devices for accessing body lumens. In an embodiment, a catheter may include a shaft having a proximal end, a distal end, and a length along a longitudinal axis extending through the shaft. A plurality of lumens may extend along the length of the shaft. At least one reinforcing filament may extend along the length of the shaft and between at least two of the plurality of lumens.
