A catheter assembly is provided having a conical diffuser tip for use in rapid infusion procedures. The conical diffuser tip provides a flared opening whereby the velocity of an infusant is decreased as the infusant travels through the catheter tip and exits into the vascular system of a patient. This decrease in velocity proportionately reduces the backpressure and / or recoil force of the catheter assembly thereby permitting the use of higher infusion rates. The catheter tip is introduced into the vasculature of a patient via a splittable introducer needle.

The invention relates to an expandable stent comprising circumferentially adjacent modules. The modules comprise longitudinally adjacent slide-and-lock radial elements which permit one-way sliding of the radial elements from a collapsed diameter to an expanded / deployed diameter, but inhibit radial recoil from the expanded diameter.

A system for connecting an accessory to a firearm having an enlarged muzzle portion has a body with a bore sized to closely receive the enlarged portion. The body has a stop to limit the insertion depth of the muzzle. A gate is received by the body for movement along the path perpendicular to the bore axis. The gate has a recessed area sized to receive the enlarged muzzle portion. A spring generates axial force to retain the muzzle portion within the recessed area. Compression of the spring enables movement of the gate to shift between an open and closed position, so that the accessory may be removed or installed when in the open position, and secured when in the closed position.

A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. A sheath pair is placed over the crimped scaffold after crimping to reduce recoil of the crimped polymer scaffold and maintain scaffold-balloon engagement relied on to hold the scaffold to the balloon when the scaffold is being delivered to a target in a body. The sheath pair is removed by a health professional before placing the scaffold within the body.

A gun flash hider, formed to include a first expansion chamber, a first flow divider, a plurality of first exhaust passages, an exhaust head, a second expansion chamber, a plurality of second exhaust passages and a second flow divider, whereby high-temperature high-pressure gas produced after firing a bullet undergoes two expansion decompressions and two flow diversion decompressions, through which the gas is sequentially discharged from the first exhaust passages and the second exhaust passages, thereby substantially reducing sonic boom volume, amount of flame and recoil force produced when firing the bullet, and increasing stability and shooting accuracy when using a gun.

An anti-recoil system for counteracting recoil in firearms and weapons using a gas actuated piston assembly is disclosed. A recoil piston is acted upon by gas pressure routed from the receiver / barrel. High pressure gas causes forward movement of the recoil piston thereby generating a force opposing the recoil generated upon firing. A shock absorbing bumper connected to the piston engages the weapon's rearwardly moving bolt assembly. The bolt assembly forces the recoil piston rearward and compresses the bumper and expanded gas in the recoil piston chamber thereby absorbing additional recoil forces. Upon reaching a rear most position a gas relief valve is opened allowing venting of the compressed gases at which point the bolt operating main spring propels the bolt assembly forward, stripping the top round out of the ammunition magazine, loading the next round, locking the bolt and freeing the firing pin to fire the next round. An electrical generation system designed to meet the current and future needs for individual combatants utilizes hereto fore wasted energies produced in the firing of a modern weapon. Specifically it is designed to convert the wasted energy contained in the ejected high pressure gasses and the subsequent recoil produced by the gasses accelerating a projectile to high velocities, and the energy contained in the rapidly moving bolt assembly. This energy is capable of being stored within the weapon, or in external, individual battery packs.

The present disclosure relates to an adapter and a mechanism for attaching accessories to support structures. The adapter generally comprises a base configured for attachment to a support structure; a housing connected to the base; at least one rotating member coupled with the housing; a locking means arranged and configured to selectively engage the at least one rotating member; an accessory attachment member configured to receive at least one accessory; and at least one arm having a first end connected to the accessory attachment member and having a second end connected to the at least one rotating member.
