Abstract:
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.
Abstract:
The present disclosure provides systems and methods for cutting mucosal tissue. In particular, the present disclosure provides an endoscopic hood with an integrated wire for single-step tissue cutting. The endoscopic hood is particularly useful for performing repeated cutting, for example EMR resections, without the need for assistance by a nurse or medical technician.
Abstract:
A device for treating tissue includes a capsule extending longitudinally from a proximal end to a distal end and including a lumen extending therein and a clip slidably received within the lumen of the capsule. The clip includes a middle prong, a first outer prong and a second outer prong. The first prong is coupled to the middle prong so that the first prong is movable relative to the middle prong between a first open configuration and a first closed configuration. The second outer prong coupled to the middle prong so that the second prong is movable relative to the middle prong between a second open configuration and a second closed configuration. The first and second outer prongs are independently movable relative to the middle prong to be moved between the first and second open configurations to the first and second open configurations and the first and second closed configurations.
Abstract:
A tissue retractor for attachment to an elongate member of a medical device. The tissue retractor includes a cap having a central longitudinal axis. The cap includes an attachment section adapted to attach to a distal end of the elongate member. The cap further includes a moveable component pivotally attached to the attachment section at one or more pivot points, and an actuator connected to the moveable component to transition the moveable component across the central longitudinal axis from an insertion state to an actuated state.
Abstract:
A device for treating a tissue opening includes a capsule extending longitudinally from a proximal end to a distal end and including a lumen extending therethrough; a pair of arms movably housed within the lumen of the capsule such that the pair of arms are movable between an open configuration and a closed configuration, the pair of arms being biased toward the open configuration such that when the pair of arms are moved distally with respect to the capsule, distal ends of the pair of arms are separated from one another to receive target tissue therebetween; a needle releasably connected to a first one of the pair of arms, the needle extending laterally inward toward a second one of the pair of arms and including a connecting structure extending along a portion thereof, the second one of the pair of arms including an opening located so that, when the pair of arms are moved to the closed configuration, the connecting structure of the needle engages the opening; and a suture extending from a portion of the needle proximally through the capsule.
Abstract:
A medical device may include an elongate member including a proximal end and a distal end. The medical device may also include a rotatable member at the distal end of the elongate member. The rotatable member may be rotatably coupled to the distal end of the elongate member. The rotatable member may include a longitudinal axis, and may be configured to rotate about the longitudinal axis. The rotatable member may also include a gripping element configured to engage a layer of tissue. The gripping element may be configured to selectively couple at least a portion of the layer of tissue to a surface of the rotatable member, to restrict relative movement between the portion of the layer of tissue and the surface of the rotatable member, during rotation of the rotatable member.
Abstract:
A medical device may include a housing. The housing may include an outer wall, an inner wall spaced from the outer wall, and a cavity between the outer wall and the inner wall. The cavity may be in fluid communication with a lumen configured to adjust pressure within the cavity. The medical device may also include a cutting tool configured to move from extending around an outer surface of the housing to entering the cavity of the housing.
Abstract:
A medical device for resecting tissue. The medical device is slidably disposed within a working channel of an elongate introduction sheath. The medical device includes an elongate shaft having a proximal end, a distal end, and a lumen extending therebetween. The distal end of the elongate shaft may include an opening in communication with the lumen. In addition, the medical device includes a support structure having a slot extending along an inner surface of the support structure in communication with the lumen of the elongate shaft. The medical device further includes a snare loop having a first position disposed within the slot of the support structure, and a second position disposed within the lumen of the elongate shaft. An actuation member is slidably disposed within the lumen of the elongate shaft and is connected to the snare loop.
