Abstract: Disclosed herein is a catheter comprising: a first portion having a proximal end and a distal end, a second portion having a proximal end and a distal end, and a third portion having a proximal end and a distal end; wherein the first and the second portions comprise an outflow lumen; wherein the third portion comprises an inflow lumen and the outflow lumen; wherein the first portion has a helical portion having a first length and extending from the distal end of the first portion toward the distal end of the second portion; and wherein the catheter is configured to be inserted into a patient body such that the first portion penetrates an atrial septum to extend into a left atrium to assist with systemic perfusion with oxygenated blood. Also disclosed are septum fixation and docking assemblies, and the systems are using the same.

Abstract: A torch device having a pivoting torch arm, including a fuel delivery system having a fuel tank and microjet burners positioned in the end of the torch arm, and an ignition system including an ignition button and a piezoelectric igniter for igniting fuel, and an interlock mechanism including a mounting tab pivotally attaching the torch arm to the body of the torch, with a guide pocket defined by a laterally-extending wall of the mounting tab, and a rocker arm having a distal arm cooperating with and confined within the guide pocket, and a proximal arm cooperating with the ignition button, and configured to prevent a user from pressing the ignition button based on the angular position of the torch arm relative to the torch body.

Abstract: A detonator system is provided for use with explosives that utilizes two subsystems. A first subsystem functions as a non-explosives based detonator, which does not contain any explosives. The second subsystem is an initiating subsystem, which includes an initiating pellet. To set off an explosive event, the non-energetics based detonator is coupled to the initiating subsystem and the non-energetics based detonator is commanded to provide a suitable signal to the initiating subsystem that is sufficient to function the initiating pellet. Further, the initiating subsystem can be integrated directly into an associated explosive such as a booster that has been configured to receive the initiator subsystem without changing the hazard class of the booster.
