GAS CANISTERS AND METHODS FOR MAKING THEM

Canisters are provided that include a cylindrical body and a cap welded to the body to define a cavity filled with carbon dioxide or other fluid. The canisters may be loaded into a medical device, e.g., to provide an energy source for operating the device. Methods for making such canisters are also provided.

Amputation system for field use

An amputation system includes a cutting element having a cutting blade traversing a V-shape. The V-shape has a vertex and an angle in a range of 90-120°. A rod, rigidly coupled to the cutting element, has its longitudinal axis aligned with the vertex so it bisects the angle of the V-shape. A barrel having a bore receives at least a portion of the rod therein wherein the rod's outboard end resides in the bore. An energetic energy source, positioned in the bore adjacent to the rod's outboard end, generates a pressure force that is incident on the rod's outboard end. The pressure force is one that peaks within 0.5 milliseconds to propel the rod from the bore at a velocity in a range of 300 to 1000 feet per second.

A surgical access device has a cannula tube with a collar coupled to a proximal region of the cannula tube. A balloon is attached to the cannula tube. The collar includes a receptacle and an inflater is insertable into the receptacle. The inflater has a body with a chamber and a first compound. A cap is attached to one end of the body and has a cavity containing a second compound. A membrane is disposed between the body and the cap and is configured to keep the first and second compounds separate. A button extends through an opening of the cap and a piston is coupled to the button. The piston includes a spike extending away from the button and is translatable in the cap between a rest position and an actuated position. The actuated position is defined by a portion of the spike penetrating the membrane such that the first compound interacts with the second compound generating a gas that is communicated to the balloon via a groove of the cannula tube.

SYSTEM FOR EFFECTING AND CONTROLLING OSCILLATORY PRESSURE WITHIN BALLOON CATHETERS FOR FATIGUE FRACTURE OF CALCULI

A dynamic balloon angioplasty system for applying a dynamic pressure to fracture hardened materials embedded within an elastic conduit. The system having a pressure source system outputting at least a first predetermined pressure from a pressure source outlet, and an angioplasty unit fluidly coupled to the pressure source outlet receiving at least the first predetermined pressure. The angioplasty unit having an angioplasty inflation device, an angioplasty balloon connector, and an oscillating mechanism selectively actuated to output a plurality of pressure pulses to the angioplasty balloon via a fluid communication path. A control system is configured to determine an optimal hydraulic pressure oscillation frequency and amplitude for a given procedure and output a control signal to the oscillating mechanism, and monitor a pressure signal to detect fracture of the hardened material within the elastic conduit or system failure or leakage.

20230363759 · 2023-11-16 ·

A stapling device includes a handle assembly, an elongate body, and an end effector. The elongate body includes a proximal portion and a distal portion. The proximal portion extends distally from the handle assembly. The end effector is operably disposed on the distal portion of the elongate body. The end effector includes a first jaw member and a second jaw member pivotally secured relative to the first jaw member. The second jaw member is movable between an open position and a closed position. The first jaw member includes at least one pusher bag. The at least one pusher bag is transformable between a deflated condition and an expanded condition. The stapling device further includes at least one staple member releasably supported within the first jaw member. Transformation of the at least one pusher bag from the deflated condition to the expanded condition ejects the at least one staple from the first jaw member.

Bleeding control device
11583284 · 2023-02-21 ·

A bleeding control device for mitigating bleeding includes an outer storage container housing, a compressed gas canister, wound blocking contents and a control element. The bleeding control device may be used to deliver variable contents to a wound at the site of injury to control the bleeding of a victim as temporary solution for mitigating the bleeding until more advanced medical care can be provided. A bleeding control device includes a canister housing, a compressed gas canister arranged within the canister housing, a tube connected to the canister housing, an inflatable balloon disposed on the tube, the inflatable balloon being fluidly connected to the compressed gas canister, and a control element configured to activate the compressed gas canister to inflate the inflatable balloon.

Intraosseous Modular Power
20220249104 · 2022-08-11 ·

An intraosseous access system, including an access assembly having a needle configured to drill into bone via rotation of the needle and a driver. The driver can include a housing, a power converter configured to impart rotational power to the needle, a first power source coupled to the power converter, and a second power source selectively coupleable to the power converter, where the second power source is configured to be disposed at least partially external to the housing. A method of drilling through a bone includes providing the intraosseous access system, applying rotational power to the needle, and placing the needle in contact with the bone. The method can further include coupling the second power source to the power converter so that power from the second power source is combined with power from the first energy source.
