US Patent:

8366733, Feb 5, 2013

Filed:

Mar 28, 2008

Appl. No.:

12/057726

Inventors:

Jonathan B. Gabel - Randolph NJ, US
Jason C. Livingston - Scotch Plains NJ, US
Dwayne Looney - Flemington NJ, US

Assignee:

Ethicon, Inc. - Somerville NJ

International Classification:

A61M 29/00

US Classification:

606192

Abstract:

An instrument for controlling bleeding includes an outer shaft having a central lumen extending between proximal and distal ends thereof, and an inner shaft disposed within the central lumen of the outer shaft, the inner shaft having a central lumen extending between proximal and distal ends thereof. The instrument has an inflatable balloon with a proximal end secured to the outer shaft and a distal end that is inverted and secured to the inner shaft. In one embodiment, the balloon has a spherical shape when the outer and inner shafts are in a first position and a toroidal shape when the outer and inner shafts are in a second position. The instrument includes an actuator for discharging a flowable material from the central lumen. In one embodiment, the instrument includes a stylet having barb-like features to attach a hemostat to the distal end of the instrument.

US Classification:

606151, 606191, 606192, 606213

Abstract:

An instrument for controlling bleeding includes an outer shaft, an intermediate shaft telescopically received within a central lumen of the outer shaft, and an inner shaft telescopically received within a central lumen of the intermediate shaft, the inner shaft having a proximal end and a distal end that extends distally from the intermediate shaft. The instrument includes a hemostat disposed at the distal end of the inner shaft, and a fluid-resistant element connected to the distal end of the outer shaft and surrounding the hemostat. The fluid-resistant element has a breakable, fluid-resistant seal at a distal end thereof that protects the hemostat from fluids until the hemostat is delivered and deployed onto tissue. In one embodiment, the instrument includes an inflatable balloon to deploy and tamponade the hemostat.

International Classification:

A61B 17/10

US Classification:

606151

Abstract:

An instrument used for the delivery, deployment, and tamponade of a hemostat such as a topically applied hemostat includes an intermediate shaft having a proximal end, a distal end, and a central lumen extending to the distal end, and an inner shaft telescopically received within the central lumen of the intermediate shaft, the inner shaft having a proximal end and a distal end that extends distally from the intermediate shaft. The instrument includes an inflatable balloon having a proximal end secured to the intermediate shaft and a distal end secured to the inner shaft, a first actuator for inflating the balloon, and a second actuator for moving the distal ends of the intermediate and inner shafts relative to one another between a first position and a second position for changing the shape of the balloon when the balloon is inflated. The proximal end of the balloon is secured to the distal end of the intermediate shaft and the distal end of the balloon is secured to the distal end of the inner shaft. The balloon has a spherical shape when the intermediate and inner shafts are in the first position and a toroidal shape when the intermediate and inner shafts are in the second position.

Abstract:

According to some aspects, a method of additive fabrication wherein a plurality of layers of material are formed is provided. The method may comprise forming a layer of material in contact with a container, and subsequent to the forming of the layer of material, actively bending the container around at least one fixed point such that the layer of material separates from the container. According to some aspects, an additive fabrication apparatus configured to form a plurality of layers of material is provided. The apparatus may comprise a container, a build platform, one or more force generators, and at least one controller configured to, subsequent to formation of a layer of material in contact with the container, actively bend the container around at least one fixed point via the one or more force generators, such that the layer of material separates from the container.

International Classification:

G03F 7/20

US Classification:

355 72

Abstract:

3D printing systems and methods avoid build-compromising misalignments through the use of a self-leveling assembly that maintains a constant and typically fully parallel orientation between a build platform and the bottom surface of a resin tank. As a result, contact between the floor of the resin tank and the build platform surface may be uniformly flat and even, and perpendicular to the z-axis motion of the deposition source.
