A medical device that may include an elongate member having a proximal end and a distal end, and a lumen disposed through the elongate member is disclosed. The medical device may also include an opening disposed at the distal end of the elongate member in communication with the lumen, and a pushing element disposed with the lumen. The medical device may also include at least one fiducial disposed within the lumen and distal to the pushing element, and a separating mechanism disposed at the distal end of the elongate member. The separating mechanism may be configured to apply a separating force to deploy the at least one fiducial.

Fiducial deployment mechanisms, and related methods of use

A suture device may include a suture translation assembly configured to be axially translatable within a lumen of a delivery system and a distal assembly configured to be securable to the distal end of the delivery system. The suture translation assembly and the distal assembly may cooperate to enable a user to pass a needle back and forth between the two in order to endoscopically suture a defect.

Suture based closure device

Polypectomy devices and methods for making and using polypectomy devices are disclosed. An example polypectomy device may include an elongate sheath having a proximal end region and a distal end region. A shaft may be slidably disposed within the sheath. A handle may be coupled to the proximal end region of the sheath. The handle may be designed to axially shift the shaft relative to the sheath. A snare may be coupled to the shaft. The snare may include a first region, a traction region, and a distal tip region. The first region may have a non-circular cross-sectional shape. The traction region may include a plurality of traction members. At a position between two adjacent traction members the snare may have a reduced cross-sectional area relative to the first region. The distal tip region may have a circular cross-sectional shape.

Polypectomy snare devices

Embodiments of the invention include an endoscope including multiple lumens for tissue acquisition and removal and related methods of use.

A tissue resection device for resecting tissue from a target site within a patient's body. The device includes an elongate shaft having a proximal end and a distal end. An actuation member extends partially through the shaft, and reciprocates within the shaft between a retracted position and an extended position. Multiple snare wires extend through the actuation member, and emerge outwards from a distal portion of the actuation member. The snare wires cooperate and join to form a snare loop, which engages the tissue intended to be resected. The snare loop is configured to enhance friction while engaging the tissue, to resect the tissue.

An articulating portion for an elongate medical device is disclosed. The articulating portion may include a plurality of segments movable relative to one another, and a plurality of hinges disposed between adjacent segments. The segments can be configured to bend at the hinges upon manipulation of a control member of the device. The segments and the hinges can also be a single continuous piece of material.

Elongate medical device with articulating portion

An endoscopic instrument comprises a first flexible insertion member sized for insertion through a body lumen to a target site and a needle coupled to the insertion member for penetration of tissue, the needle including a plurality of flexibility enhancing grooves formed therein along at least a first portion of the length of the needle.
