Abstract:
A medical device may comprise a handle portion; an insertion portion having a proximal end portion at the handle portion, wherein the insertion portion includes a lumen therein and a distal end having a distal opening in communication with the lumen; and a member disposed within the lumen, the member having a distal end portion with an imaging device. The member may be configured to transition between a first configuration and a second configuration. In the first configuration, the imaging device may face distally, and, in the second configuration, the imaging device may face proximally. Extending the distal end portion of the member distally past the distal opening may cause the member to transition from the first configuration to the second configuration.
Abstract:
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.
Abstract:
A medical cleaning valve (or cleaning valve) may be configured to provide cleaning functionality to fluid (e.g., air and water) channels of an endoscope. Many embodiments described herein may include a cleaning valve (or valve) that is appropriate for single-use and therefore may be disposable. Accordingly, the valve may be made from a limited number of parts and materials, e.g., to limit its cost and/or manufacturing complexity. For example, multiple seals may be integrally formed with a valve stem. In another example, the valve may have an interface member, which may combine and simplify the functionality of a number of components, such as by connecting the valve stem to a valve well, sealing an opening to a lumen in the valve stem, and/or biasing the valve stem into a position relative to the valve well.
Abstract:
The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to devices, systems and methods for air/water and flushing valves. For example, an endoscopic valve of the present disclosure may include a valve stem with contiguous first and second channels and with first and second ports formed within a sidewall of the valve stem. A series of seals may be disposed around an outer surface of the valve stem proximal and distal to the first and second ports. A gating member may be slidably disposed within the proximal channel and a valve insert may be disposed between the proximal and distal channels.
Abstract:
A biopsy needle system includes a needle extending from a tissue piercing distal end to a proximal end. The needle defines a lumen extending from the distal end at least a portion of a length thereof and houses a target tissue. The system also includes an elongated member defining a channel therethrough open at a proximal end. The channel is sized and shaped to permit passage of the needle therethrough. Further, the system includes an end cap coupled to the distal end of the elongate member. The end cap includes a hole extending through a lateral wall thereof. The hole is sized and shaped to permit passage of the needle therethrough. The end cap further includes a ramp extending from the channel to the hole to guide the needle through the hole. The ramp is angled with respect to a longitudinal axis of the elongated member.
Abstract:
The present disclosure is directed to a delivery catheter with a mechanism of discharging an adhesive during and/or immediately prior to deployment of the medical device by the delivery catheter.
Abstract:
A stent delivery device is provided that includes an outer tubular member, an intermediate tubular member disposed and slidable within a lumen of the outer tubular member, and a plurality of elongate members slidable within the intermediate tubular member. The plurality of elongate members have distal end structures that are moveable between a stent retaining configuration to selectively retain a stent and a stent releasing configuration to selectively release the stent.
Abstract:
A stent has a braided wire body formed from at least a first wire and a second wire. The first wire has a first cross-sectional area and the second wire has a second cross-sectional area different from the first cross-sectional area. The proximal end of the braided wire body has a plurality of peaks, the peaks including first peaks and first loop ends. The first loop ends alternate circumferentially with the first peaks and the first loop ends extend proximally beyond the first peaks.
Abstract:
A medical device includes a handle, a flexible member extending from a proximal end connected to the handle to a distal end, a rotation mechanism connected to the distal end of the flexible member, an end effector coupled to a distal portion of the rotation mechanism and a push member extending through the handle and flexible member and connecting to the rotation mechanism, the rotation mechanism being configured and dimensioned to convert axial movement of the push member into rotation of the end effector.
Abstract:
Devices, systems, and methods for applying an elongate member to a shaft of an endoscope. The system may include a flexible elongate member and a tool for applying the elongate member to the shaft of the endoscope. The tool may include an elongate support and a plurality of connectors. The plurality of connectors may be longitudinally spaced apart along the elongate support(s). The plurality of connectors may be releasably coupled with the flexible elongate member at two or more locations along the flexible elongate member when the flexible elongate member is in a helical configuration.
