The present disclosure relates to injectable compositions sterile injectable fluid compositions comprising a polysaccharide having a color in the visible spectrum, methods of forming the same, kits containing the same, and methods for performing agent-assisted procedures in a patient using the same.

Injectable compositions

A system may include an elongate flexible device, a flexible instrument, and a processor. The elongate flexible device may include a first shape sensor configured to generate first shape data corresponding to a shape of the elongate flexible device. The flexible instrument may include a second shape sensor configured to generate second shape data corresponding to a shape of the flexible instrument. The processor may be configured to register the flexible instrument to the elongate flexible device based on the first shape data and the second shape data. The first shape data and the second shape data may be generated while the flexible instrument is mated with the elongate flexible device.

Ultrasound elongate instrument systems and methods

The present disclosure is directed to a medical instrument. The medical instrument may include a delivery device and a retraction mechanism including a target tissue anchor and a first stabilizing anchor, wherein the target tissue anchor attaches to target tissue and connects to the delivery device.

Tissue retraction devices and related methods of use

A handle for a medical device includes a distal portion extending longitudinally and including a distal channel extending therethrough, the distal end of the distal portion including a connector configured to connect to a proximal end of an endoscope, a central portion slidably connected to the distal portion, the central portion extending longitudinally. The handle also includes a central channel extending therethrough, the distal end of the central portion connected to a sheath, the central portion including an introducer port extending laterally therefrom so that an auxiliary tool inserted through the introducer port is directed through a lumen of the sheath. Further, the handle includes a proximal portion slidably connected to the central portion, the proximal portion extending longitudinally and including a proximal channel extending therethrough, the distal end of the proximal portion connected to a needle so that the needle is passed through the lumen.

Scope-mounted inod handle

A device for treating a tissue opening includes a proximal portion including an elongated flexible member, a capsule releasably coupled to a distal end of the flexible member and including a lumen extending therethrough and a clip including a pair of arms movably housed within the capsule. A suture extending along a first one of the pair of arms and including a loop at a distal end thereof extending across an opening extending through the first one of the pair of arms. A suture grabbing element extending laterally from a second one of the pair of arms and including a hook so that, when the pair of arms are moved toward a closed configuration, the hook extends through the opening to grab the loop and draw the distal end of the suture from the first one of the pair of arms toward the second one of the pair of arms.

Hemostatic clip with needle passer

According to one aspect, an instrument may include a sheath having a distal end. The instrument also may include a fluid cannula at the distal end of the sheath. The instrument also may include a cutting electrode at the distal end of the sheath. At least one of: (i) an exterior surface of the fluid cannula, and (ii) a cutting electrode surface that faces the exterior surface, is longitudinally slidable along the other of the exterior surface and the cutting electrode surface during movement of at least one of the cutting electrode and the fluid cannula relative to the other of the cutting electrode and the fluid cannula.

Multifunctional electrosurgical instruments with dynamic electrode assemblies

According to one aspect, a medical system may include an instrument including an end effector for acting as a monopolar electrode. The end effector may be configured to be positioned in a body of a subject and emit radiofrequency energy towards a target area in the body. The medical system may further include a return electrode. The return electrode may be deliverable within the body proximate the target area and separately from the instrument and the monopolar electrode. The return electrode may be configured to contact tissue in the body proximate the target area and receive radiofrequency energy emitted from the end effector.

Methods and devices for performing electrosurgery

The present disclosure relates to the field of tissue dissection. Specifically, the present disclosure relates to medical devices which lift and retract tissue during a dissection procedure to improve visualization of the target tissue and mitigate obstruction of dissection tools. In particular, the present disclosure relates to a tissue retraction device which moves from a constrained to relaxed configuration to immobilize and retract the dissected portion of target tissue during a dissection procedure.

Tissue retraction device

The present disclosure relates to the field of medical devices generally and specifically, to endoscopic systems and methods for resection of malignant and pre-malignant lesions within the gastrointestinal (GI) tract. In particular, the present disclosure relates to systems and methods for delivering injectable compositions between tissue layers (e.g., between the muscularis and submucosa layers) to elevate and stabilize the lesion for fast and efficient resection.

Systems and methods for submucosal tissue separation

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

According to one aspect, a tissue fastening device may include a handle assembly including at least two actuators. The tissue fastening device may also include a first body extending distally from the handle assembly and defining a longitudinal axis. The tissue fastening device may also include a fastening device coupled to a distal end of the first body. The fastening device may include a longitudinal body including a channel, a cartridge configured to include a plurality of fasteners, a longitudinal channel configured to receive a device for cutting tissue, an anvil rotatable relative to the cartridge, and a fastener actuator. The fastener actuator may be coupled to one actuator of the at least two actuators and configured to move proximally relative to the cartridge to deploy the plurality of fasteners from the cartridge.

Systems, devices, and related methods for fastening tissue

Exemplary medical devices may include a snare device. The snare device may include a first leg having a proximalmost end and a second leg having a proximalmost end. The first leg and the second leg may form a distal loop. The proximalmost end of first leg may be independently moveable relative to the proximalmost end of the second leg.

Medical device and related methods

A device for passing a needle and suture longitudinally through a target tissue includes a proximal jaw including a proximal recess and a proximal retention mechanism for releasably engaging a first end of a needle received within the proximal recess and a distal jaw movably coupled to the proximal jaw such that the proximal and distal jaws are longitudinally movable relative to one another. The distal jaw includes a distal recess and a distal retention mechanism for releasably engaging a second end of the needle received within the distal recess. The proximal and distal jaws are movable between a first state, in which the proximal retention mechanism is in a locked configuration and the distal retention mechanism is in an unlocked configuration, and a second state, in which the proximal retention mechanism is in an unlocked configuration and the distal retention mechanism is in a locked configuration.
