A medical system includes a source of a material, a first tube, and a second tube. The material is configured to expand and form a porous body after the material is deployed into a body lumen. The first tube is configured to deliver the material into the body lumen, and the second tube is configured to apply suction to the porous body.

Medical systems, devices, and related methods

In one aspect of the present disclosure, an apparatus for delivering a powdered agent into a subject's body may include a powder chamber housing the powdered agent. The apparatus also may include a chassis in fluid connection with the powder chamber. The chassis may include a first passage for receiving a pressurized gas, a second passage for receiving the powdered agent from the powder chamber, and a junction in fluid communication with the first passage and the second passage. At least a first portion of the pressurized gas is introduced into the powdered agent at the junction to fluidize the powdered agent.

Apparatuses and methods for delivering powdered agents

A device for delivering an agent may comprise a chamber for receiving agent through an agent inlet; and a body received within the chamber. The body may be movable in first and second directions along a longitudinal axis of the chamber. In a first configuration of the body, an amount of the agent may flow into the chamber via the agent inlet. In a second configuration of the body, the agent is prevented from flowing into the chamber via the agent inlet. When the body is transitioned from the first configuration to the second configuration, the amount of the agent may be moved from a first position along the longitudinal axis of the chamber to a second position along the longitudinal axis of the chamber.

Devices and methods for delivering powdered agents

The present disclosure relates generally to the field of medical devices and medical device delivery. In particular, the present disclosure relates to medical devices, systems, and methods for delivering a barrier device within a body lumen of a patient, such as the GI tract. For example, a barrier device may include a distal self-expanding stent. A tubular barrier may have a proximal end, a distal end, and a lumen extending therethrough. The distal stent may be disposed at the distal end of the tubular barrier. An anchoring self-expanding stent may be disposed at the proximal end of the tubular barrier.

Barrier devices, systems, and methods

A medical device comprising a housing defining at least one enclosure for storing agent in a first form, a force applicator within the housing and adjacent the enclosure, a drive mechanism for moving the agent toward the force applicator, wherein the force applicator defines a surface for applying a force to the agent to separate the agent into particles smaller than a size of the first form, and wherein the device defines a lumen for receiving the particles from the force applicator and for receiving a pressurized fluid to propel the particles through the lumen.

Agent delivery device

An implantable device having an adjustable passage therethrough. The passage may be adjustable to occlude or otherwise to regulate access or flow of materials therethrough. An elongated element may be inserted into the passage when in a closed configuration to selectively open the passage. For instance, the implantable device may be a tubular device with a twisted region closing the passage therethrough, and the elongated device may be configured to engage such twisted region and to be rotated to untwist the closed region. An additional tubular device with a passage therethrough may be inserted into the passage of the implantable device to hold open the passage for a selected period of time.

Devices, systems, and methods for adjusting a passage through an implantable device

A device may be configured to deliver an agent to a target tissue via a pressurized fluid and the device may include a catheter including a lumen; an enclosure configured to store the agent, receive the pressurized fluid, and release a combination of the pressurized fluid and the agent; and a valve downstream of the enclosure to receive the combination of the pressurized fluid and the agent from the enclosure. The valve may have a first configuration preventing a flow of the combination through the lumen and a second configuration permitting the flow of the combination through the lumen.

Medical devices for agent delivery and related methods of use

A medical system includes a handle, a sheath extending from the handle, and an end effector connected to a distal end of the sheath, where the end effector directs a mass of material towards a target site of a body and cause release of the material onto the target site.

Medical delivery device and method of use

A device for delivering an agent may comprise: a housing defining an enclosure. The housing may be configured to store an agent. The device may further comprise an inlet, in fluid communication with the enclosure, for receiving a flow of pressurized fluid; an outlet in fluid communication with the enclosure; and a filter disposed within the enclosure. Pores of a wall of the filter may be configured such that the fluid is permitted to pass through the pores into a channel defined by an inner surface of the wall. An actuation member may be configured to transition between a first configuration, in which portions of the agent disposed proximally to the actuation member are prevented from passing distally of the actuation member, and a second configuration, in which portions of the agent disposed proximally of the actuation member are capable of passing distally of the actuation member.

This disclosure relates generally to the field of devices and procedures for forming an opening between adjacent tissue structures. For example, in an embodiment, a system for forming an opening between body lumens may include a delivery catheter. A first access element may be configured to be positioned against a first body lumen disposed about a distal end of the catheter. A second access element having an outer diameter that substantially matches an outer diameter of the first access element may be disposed about the distal end of the catheter. The second access element may be configured to be positioned against a second body lumen and axially aligned with the first access element. A filament may be electrically coupled to one or both of the first and second access element.

Devices, systems, and methods for forming an opening between body lumens

Systems and methods of delivering a patch to a target site of a patient are described herein. The patch may comprise a biomaterial such as chitosan or extracellular matrix and may be biocompatible and/or bioresorbable. The system may include an endoscope, a patch, and one of an instrument or a cap, the patch being coupled to the respective instrument or cap and detachable therefrom. Methods of delivering the patch to the target site may include introducing an endoscope into a gastrointestinal tract of a patient, e.g., the patch being in a folded or crimped configuration, navigating a distal end of the endoscope proximate a target site; and applying the patch to the target site while releasing the patch from the endoscope.

Devices and methods for endoscopic patch delivery

A device for fluidizing and delivering a powdered agent, including a canister extending longitudinally from a first to a second end and defining a space within which a powdered agent is received, an inlet coupleable to a gas source for supplying gas to the space to fluidize the powdered agent to create a fluidized mixture, an outlet via which the gas mixture is delivered to a target area, a tube extending from the outlet into the interior space, the tube including a slot extending through a wall thereof so that gas mixture is passable from the interior space through the outlet via the second end and the slot, and a door movably coupled to the tube so that the door is movable over the slot to control a size of the slot open to the interior space of the canister.

Fluidization devices and methods of use

A medical device includes a sheath having a proximal end, a distal end, and at least one lumen extending from the proximal end to the distal end, and a balloon at the distal end of the sheath and having an inflated configuration and a deflated configuration.
