Abstract: A tissue-manipulating system including a tissue-manipulating device having shaft and a tissue grasper assembly. The tissue grasper assembly has at least one grasper arm resiliently expandable from a closed configuration, within and extending along the longitudinal axis of a shaft, to an open configuration outside the shaft with the grasper arm expanded in a direction transverse to the longitudinal axis of the shaft. In the open configuration, the at least one grasper arm may be engaged with tissue wall to manipulate or move the tissue wall, such as to move a distal tissue wall closer to a proximal tissue wall. The tissue grasper assembly may be deployable (such as by being separated from the shaft), such as to remain in place holding two tissue walls in apposition.

Abstract: 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.

Abstract: Implementations of a delivery device and method are disclosed. One implementation is a delivery device comprising a flow chamber with an inlet port for receiving a fluid flow in the flow chamber, and an outlet port for exiting a material from the flow chamber. The flow chamber may include a formation portion in which a suspension of the material is formed, and a collection portion that directs the suspension toward and/or into the outlet port. An amount of the material may collect in the collection portion adjacent the outlet port. The device may further comprise an insertion port for permitting insertion of the material in the flow chamber, and/or a pusher operable to move the amount of material through the outlet port. Related devices and methods also are disclosed.

Abstract: 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.

Abstract: A medical device may comprise a handle and a flexible sheath extending from the handle. The sheath may include a first chamber configured to receive a first agent and a second chamber configured to receive a second agent. Each of the first chamber and the second chamber may be disposed in a distal portion of the sheath. The sheath may also include a first piston received within the first chamber and a second piston received within the second chamber and at least one actuation element configured to transmit a force from the handle to each of the first piston and the second piston. When the handle is in a first configuration, the first agent may be maintained within the first chamber and the second agent is maintained within the second chamber. When the handle is in a second configuration, the first agent may be released from the first chamber to mix with the second agent.

Abstract: An apparatus for delivering a powdered agent into a subject's body may include a first passage for receiving a pressurized gas. The apparatus also may include a container housing a powdered agent. The container may be in fluid connection with the first passage. At least a portion of the pressurized gas is introduced into the powdered agent in the container to fluidize the powdered agent. The apparatus also may include a second passage for receiving the powdered agent from the container. In a first configuration of the apparatus, the second passage may not be in fluid connection with the container. In a second configuration of the apparatus, the second passage may be in fluid connection with the container. The apparatus may be configured to transition between the first configuration and the second configuration.
