    Abstract: A medical system includes a medical device having a handle, a shaft, an actuation member, and medical system also includes a cartridge and a plunger. The handle includes an actuator movable relative to the handle, and the actuator is coupled to a distal end of the shaft via the actuation member. The cartridge contains a treatment agent, and the cartridge is couplable to the distal end of the shaft. The plunger is movable relative to the cartridge. Movement of the actuator controls movement of the actuation member. Movement of the actuation member controls movement of either the plunger or the cartridge to control a delivery of the treatment agent from the cartridge.

  • Publication number: 20230277815
    Abstract: An elongate medical device is adapted to provide adjustable flexibility. The elongate medical device includes an inner coil having one or more inner coil filars extending in a first direction, and an outer coil having one or more outer filars extending in a second direction. A hypotube extends proximally from the inner coil and the outer coil. A cable extends through the inner coil and through the hypotube, where a distal end of the cable, a distal end of the inner coil and a distal end of the outer coil are all secured together at a distal end of the elongate medical device, such that applying a tensile force to the cable, relative to the hypotube, causes the inner coil and outer coil in combination to increase in stiffness.

  • Publication number: 20230248559
    Abstract: An implantable device configured to be deployed at a deployment site such as across a body passage. The implantable device has features enhancing the resistance of at least a portion of the implantable device to migration from the deployment site. The implantable device may have surfaces contacting tissue at the deployment site which are configured to promote tissue ingrowth with respect to the implantable device. Surfaces of the implantable device not contacting tissue may be enlarged and coated with a coating material increasing the strength of the coated portions of the implantable device to resist migration of the implantable device with respect to the deployment site.

  • Publication number: 20220346998
    Abstract: A mesh element having a mesh gauge selected to control flow of materials therethrough. The mesh element is implantable into an anatomical structure upstream of a body passage or within a body passage to control flow of materials through the body passage. The mesh element may be coupled to a support structure to facilitate anchoring of the mesh element in place relative to the body passage. The support structure may have a lumen defined therethrough to allow flow of materials through the body passage, with the mesh element regulating the flow of materials into the lumen. The mesh element alternatively may be directly coupled to an anatomical structure upstream of a body passage to regulate or determine flow of materials through the body passage.
