Abstract:
A catheter, comprising: an ambidextrous control having a right-handed configuration and a left-handed configuration, the control including a body and a handle coupled to the body to permit change of the handedness of the control, wherein the handle has a first orientation relative to the body when the control is in the right-handed configuration, and the handle has a second orientation relative to the body when the control is in the left-handed configuration, the second orientation being different from the first orientation; and a distal section, wherein applying a force to the handle actuates the distal section.
Abstract:
An endoscopic device and method is disclosed. The device may comprise a shaft extending between a distal end and a proximal end. The shaft may include a controllable bend, a lumen, and a controllable channel movably set in the lumen. The device may further comprise a handle at the proximal end of the shaft. The handle may include a controller selectively engageable with the at least one controllable bend and the controllable channel. The methods may comprise steps for operating the device.
Abstract:
A stent of the present disclosure has a variable radial force along the longitudinal length of the stent. In particular, the radial force of the center is greater than the radial force of the ends of the stent. Without being bound by theory, the radial force is affected by the strut angle θ, the wall thickness t, the number of strut pairs, and combinations thereof. In one aspect of the present disclosure, the stent has a variable strut angle θ, a variable wall thickness t, and a variable number of strut pairs. By adjusting the strut angle θ, the wall thickness t, and the number of strut pairs of the serpentine bands, the stent will have a variable radial force without the need for additional processing steps.

Abstract:
Embodiments of the invention may be directed to apparatuses for securing and sealing tissue and related methods of use. The apparatus may include an outer housing defining a first lumen, an elongate member defining a second lumen, the elongate member being configured to be disposed in the first lumen, and a securing mechanism configured to secure tissue around a distal portion of the elongate member. The elongate member and the outer housing may be longitudinally moveable relative to each other.
