Abstract: A medical device crimping system comprises a crimper and a plurality of protective strips. The crimper defines a crimping iris, which has an open state and a closed state. In the open state the cross-sectional area of the crimping iris is greater than in the closed state. The plurality of protective strips extend longitudinally through the crimping iris. Each of the strips is radially offset from one another. The strips protect the stent from direct contact with the crimping blades of the crimper.
Abstract: A method for percutaneously implanting a medical catheter, such as a gastrostomy feeding tube, and a medical catheter implanting assembly. In one embodiment, the implanting assembly includes a gastrostomy feeding tube, an inner sheath and an outer sheath. The feeding tube has an internal bolster integrally formed at its distal end. The inner sheath includes a bore extending distally from its proximal end to a point prior to its distal end and a transverse window communicating with the bore. The outer sheath includes a proximal end, a distal end and a longitudinal bore. The outer sheath is inserted over the inner sheath, and the feeding tube is inserted into the inner sheath, with the internal bolster being folded and tucked into the window and retained therein by the outer sheath. Movement of the outer sheath relative to the inner sheath to expose the window allows the bolster to decompress.

Abstract: The present application includes devices, systems and methods for therapeutic agent delivery. A device in accord with the invention may include a first infusion lumen having a proximal end, a distal end, a longitudinal axis and a therapeutic agent. This device may also include an inflatable balloon in fluid communication with the first infusion lumen, the inflatable balloon having an exit outlet wherein the device is configured to exert pressure at a target site with an external surface of the balloon, the exerted pressure greater than a target pressure prior to the therapeutic agent exiting the inflatable balloon. A method in accord with the invention may include positioning a delivery device near an intended treatment site, injecting therapeutic agent through an infusion lumen into an inflatable balloon, and determining a target pressure at a target site by monitoring the blood pressure of a patient.
Abstract: A distal assembly of an endoscopic surgical device, and a related method, having a first arm and a second arm pivotal relative to the first arm. Each arm is configured to hold a part of a two-part fastener at a distal end of the arm. A closing mechanism is positioned proximate a proximal end of each of the first and second arms opposite the distal end of each of the first and second arms. The closing mechanism is configured to move in relation to the first and second arms so as to close over at least one of the first and second arms to cause the distal ends of the arms to come together. An actuation member is also attached to the closing mechanism actuable to cause the closing mechanism to move in relation to the first and second arms.
Abstract: A method includes actuating a lever to move a cannula of a medical instrument from a first extended position to second retracted position; and actuating the lever to move a stylet of the medical instrument from a third extended position to a fourth retracted position. Actuating the lever comprises moving the lever from a first lever position spaced apart from a housing of the medical instrument to a second lever position closer to the housing.
