A method of suturing provides an endoscopic suture system. The endoscopic suture system has a needle coupled with a suture. The needle is configured to rotate in a first rotational direction. The system has a cable configured to move in a first direction and a second direction. The cable and the needle are configured to movably couple and uncouple. When the cable and the needle are coupled, movement of the cable in the first direction causes rotation of the needle in the first rotational direction. The method pulls the cable in the second direction, without rotating the needle, to cause coupling of the cable with the needle. The method pulls the cable in the first direction, after the needle and the cable are coupled, to rotate the needle.

A method cinches a suture. The method provides a cinch having a suture capturing portion configured to capture a suture, a cinch lock coupled with the suture capturing portion, and a cinch anchor having a lumen. The suture capturing portion is extended out of the lumen to capture the suture. The suture is captured by the suture capturing portion. The suture capturing portion is retracted into the lumen of the cinch anchor. The suture is cinched between the cinch lock and the cinch anchor.

A system to detect a position of a cannula may include a cannula, which may include a distal tip and an inner lumen. Also, the system may include an optical fiber, which may be disposed within the inner lumen of the cannula and may include a first end, a second end, and a U-shaped portion disposed between the first end and the second end. The U-shaped portion may be at least proximate the distal tip. Further, the system may include a light emitter, which may be coupled with the first end of the optical fiber, and a light receiver, which may be coupled with the second end of the optical fiber. Moreover, the system may include an electronic processor. The electronic processor may be coupled with the light receiver and configured to detect a decrease in an intensity of light received at the light receiver.

An infusion set includes a base () and a flexible catheter () movable from a first catheter position disposed substantially entirely within the base () to a second catheter position in which a free end of the catheter () is disposed externally of the base (). An introducer needle () is located within the catheter () and is movable between a first introducer needle position disposed substantially entirely within the base () and a second introducer needle position in which a free end of the introducer needle () is disposed externally of the base (). A spring () is activated to move the catheter () from the first to the second catheter position and the introducer needle () from the first to the second introducer needle position to facilitate insertion of the catheter (). The introducer needle () is thereafter moved by the spring () back to the first introducer needle position to store the introducer needle () within the base () with the free end of the catheter () remaining disposed externally of the base ().

Embodiments of the disclosure include an endoscope accessory assembly for use on an endoscope, during procedures. The endoscope accessory assembly may comprise an accessory device comprising a first base, a plurality of flexible struts, and webbing connecting each of the flexible struts. The accessory device is configured to receive a distal end of an endoscope. The endoscope accessory assembly may further comprise a dimension-compensating component comprising a second base, a plurality of flexible arms extending radially out from the second base, and at least one chamber at a distal end of the flexible arms. The accessory device is configured to be over-molded onto the dimension-compensating component in order to form the endoscope accessory assembly.

Provided herein is an endoscopic suturing system configured for attachment to, and use with, an endoscope.

Embodiments of the present disclosure are directed to cannulating devices and methods for exchanging cannulating devices in an endoscopic procedure. In one implementation, an apparatus for endoscopic operations is described. The apparatus includes a cannulating device to be introduced through an internal lumen of an endoscope via a biopsy port. The cannulating device has an elongated body. The elongated body includes a guidewire lumen configured to receive a guidewire therein, and a slit extending over at least a portion of the length of the elongated body from a distal tip to a proximal position of the elongated body.

Embodiments of the present disclosure are directed to apparatuses, systems, and methods for merging a balloon catheter onto a locked guidewire. In one implementation, a balloon catheter may include an inflatable balloon affixed thereto and a slit extending from a distal end of a guidewire lumen to a position proximal of the balloon. The slit may be widened by a working member of an adapter to allow passage of the locked guidewire into the guidewire lumen of the balloon catheter. The balloon catheter may be merged onto the guidewire via the slit and delivered to the desired treatment device without requiring the guidewire to be unlocked. Advantageously, access to at least one desired treatment site may be maintained with the guidewire during merging of the balloon catheter.

Embodiments of the present disclosure are directed to apparatuses, systems, and methods for merging an endoscopic basket delivery catheter onto a fixed guidewire. In one implementation, a catheter may include a sheath having a saddle secured to a distal portion thereof. The sheath may constrain an endoscopic tool such as a basket therein, while the saddle may receive a portion of a guidewire. The saddle may include a slit extending along its longitudinal length. The slit may be widened by a working member of an adapter to allow passage of a locked guidewire into the guidewire lumen of the saddle. The catheter may be merged onto the guidewire via the slit and delivered to the desired treatment device without unlocking of the guidewire. Advantageously, access to at least one desired treatment site may be maintained with the guidewire during merging of the catheter.

Embodiments of the present disclosure are directed to systems and methods for device exchange in an endoscopic procedure. In one implementation, a system for device exchange in an endoscopic procedure includes an elongated device having a slit extending from a distal end to a proximal end of the elongated device, a main block, and an adapter. The main block is configured to be affixed to a port of an endoscope. The main block includes a main channel for receiving a guidewire and the elongated device. The adapter can be engaged with the main block and configured to merge the guidewire into the elongated device. The adapter includes a working channel for receiving the elongated device and a working member raising from an inner wall of the working channel. When the elongated device passes through the working channel, the working member wedges open a portion of the slit of the elongated device such that a portion of the guidewire merges into the elongated device through the opened portion of the slit.

Systems and methods for device exchange in an endoscopic procedure

Embodiments of the present disclosure are directed to apparatuses, devices, and methods for secure connections between tubular structures. In one implementation, a first tube constructed of nitinol may have windows formed on an end thereof. A second tube constructed of stainless steel tube may be inserted within the first tube, and the windows may be filled with adhesive or solder. The adhesive or solder may bond with the first tube, forming connection pins which secure the tubes together. In some embodiments, the connected tubes may form an endoscopic needle. The nitinol portion of the needle may be sufficiently flexible for positioning within the bending section of an endoscope without deformation. The stainless steel portion of the needle may render the needle significantly less expensive than prior needles constructed solely of nitinol.
