摘要： Medical stent designs are disclosed. An example stent includes a tubular scaffold having a proximal end and a distal end. The tubular scaffold includes a first filament extending between the proximal end and the distal end, the first filament including a first biodegradable region positioned adjacent to a second biodegradable region. Further, the first biodegradable region includes a first biodegradable material, the first biodegradable material having a first rate of degradation. The second biodegradable region includes a second biodegradable material, the second biodegradable material having a second rate of degradation, wherein the first rate of degradation is different from the second rate of degradation.

摘要： The present disclosure relates generally to devices and methods for treating a tissue defect, for example, by suturing. In some embodiments, a suturing device may include an elongate member having a working channel, a suture channel, and a suture arm extending from the elongate member. The suturing device may further include a needle passer located within the working channel, the needle passer operable to deliver a needle between the elongate member and a distal end of the suture arm for suturing a target tissue, and a suture extending through the suture channel, wherein the suture is coupled to the needle. The suturing device may further include a plurality of imaging devices, wherein a first imaging device is positioned along a distal face of the elongate member, and wherein a second imaging device is positioned along the suture arm.

摘要： The present disclosure includes devices, systems, and methods for reducing signal noise in endoscopic rotational imaging. Many embodiments include an elongate member that includes an impedance matching network disposed between a proximal imaging core and a distal imaging core. In many such embodiments, the elongate member may connect a controller at the proximal end and include a rotational transducer at the distal end. In various embodiments, the proximal and distal imaging cores may include a plurality of insulated conductors disposed within a shield (e.g., a shielded twisted pair (STP)). In various such embodiments, the insulated conductors may be utilized to communicate differential signals between the controller and the rotational imaging transducer. In some embodiments, the insulated conductors in the proximal imaging core may have a larger diameter than the insulated conductors in the distal imaging core.

摘要： This disclosure relates to the field of luminal surgery. Specifically, the present disclosure relates to medical devices that expand within a body lumen for accessing a target tissue. In an aspect, an expandable device for a body lumen may include a filament comprising a proximal end, a distal end, and a length. The device may include a plurality of segments. Each segment may comprise a middle portion comprising a longitudinal axis extending axially therethrough, a projection portion extending from an end of the middle portion along the longitudinal axis, and a receptive portion extending from an opposing end of the middle portion away from the longitudinal axis, the receptive portion configured to receive the projection portion of an adjacent one of the plurality of segments. An aperture may be disposed through the projection portion, the middle portion, and the receptive portion.

摘要： The present application relates to medical devices for establishing an anastomosis between body lumens. In one example, an elongate member is configured to move between a first configuration and a second configuration. The elongate member may comprise a first end, a second end, and a middle segment extending therebetween. In the second configuration, each of the first and second ends may bend towards a center plane of the middle segment in a bent back end and form one or more loops.

摘要： The present disclosure relates to the field of tissue closures including medical devices that close openings in tissue during a surgical procedure. In particular, the present disclosure relates to devices that transition from a constrained to an unconstrained configuration to engage tissue on opposing sides of a tissue opening, and hold opposing tissue portions together to maintain the opening in a closed configuration.

摘要： A valve for use in an endoscope may comprise a proximal valve stem member having a first lumen extending from a proximal opening at a proximalmost end of the proximal valve stem member to a distal opening at a distalmost end of the proximal valve stem member. A distal valve stem member may have a second lumen with a proximal opening at a proximalmost end of the distal valve stem member. The proximalmost end of distal valve stem member may be received within the distal opening of the first lumen. The distal valve stem may be movable relative to the proximal valve stem.

摘要： Methods and systems for providing a flow of fluid to an endoscope. An illustrative container, manifold, and tubing set arranged and configured to couple to an endoscope may comprise a fluid container, a manifold fluidly coupled to the fluid container, and one or more tubing sets coupled to the manifold. The manifold may include an irrigation conduit for providing irrigation fluid from the fluid container to the endoscope, a lens wash chamber configured to receive liquid from the irrigation conduit. In some cases, the manifold may include a pressurized chamber and an adjustable barrier or divider between the pressurized chamber and the lens wash chamber. The adjustable barrier or divider may adjust to push liquid through an outlet in communication with the lens wash chamber in response to the pressurized chamber receiving pressurized gas.
