Abstract: A system suitable for delivering a therapeutic agent to a target site may include a container for holding a therapeutic agent; a pressure source having pressurized fluid, the pressure source in selective fluid communication with at least a portion of the container; a catheter in selective fluid communication with the container and configured for delivery of the therapeutic agent or the pressurized fluid to a target site; and a housing configured to securely retain the container and movably support a switch, where the switch is movable between a first position and a second position, where when the switch is in the first position, delivery of the therapeutic agent is prevented while delivery of the pressurized fluid is permitted, and where when the switch is in the second position, delivery of the therapeutic agent is permitted.

Abstract: A system for delivering an agent including a plurality of particles to a target site. The system incudes a catheter having a first wall defining an inner lumen for delivery of the agent to the target site, and a second wall surrounding the first wall to define an outer lumen therebetween for delivery of a fluid to the target site. The catheter has a distal end terminating with a primary opening of the inner lumen and a secondary opening of the outer lumen. A hub associated with a proximal end of the catheter includes a first inlet for receiving a supply of the agent and a second inlet for receiving a supply of the fluid, wherein the first inlet is in fluid communication with the inner lumen, and the second inlet is in fluid communication with the outer lumen.

Abstract: An adaptor and method for connecting a medical device to an endoscope are provided where the adaptor and the endoscope have non-compatible connectors. The adaptor includes a first portion including a proximal end portion having a mating connector for connecting to the elongate medical device and a distal end adapted to operably connect to an accessory channel of the endoscope. The first portion also includes a flange positioned distal to the mating connector and having a diameter greater than a diameter of the mating connector and a tubular body extending distally from the flange to the distal end, the tubular body being sized and shaped for insertion at least partially into the accessory channel. A lumen of the first portion extends through the first portion from the proximal end portion to the distal end where the lumen is adapted to receive a portion of the medical device therethrough.
