US Patent:

6604813, Aug 12, 2003

Filed:

Jul 6, 2001

Appl. No.:

09/900659

Inventors:

Ronald L. Green - Danbury CT

Assignee:

Illinois Tool Works Inc. - Glenview IL

International Classification:

B41J 216

US Classification:

347 47, 347 25, 347 40

Abstract:

An improved fluid jet device and method of keeping a fluid jet head clean are provided. The face of the fluid jet head includes one or more orifices, through which fluid is jetted. The orifices are formed through convex ridges at the surface of head. In a preferred embodiment of the invention, the slope from the face to the orifice is either generally constant or decreasing, to provide the convex shape. In an embodiment of the invention, air is blown over the ridge and over the orifice, to keep dust and debris away from the orifice. The flow of air, the shape of the ridge and the proximity of material on which printing occurs can be constructed and arranged to provide laminar flow of air or other gas over the orifice. The downstream side of the ridge from the orifice can have a shallower slope than the upstream side. A vacuum port can be provided on the downstream side.

International Classification:

A61B 18/14

Abstract:

A surgical instrument includes a housing and a motor. An elongated member extends from the housing. An end effector is at a distal end of the elongated member. The end effector includes a jaw member including a guard. The guard has a number of serrations extending from a proximal end of the jaw member to a distal end of the jaw member. The guard defines corresponding pockets between the serrations. The guard is coupled to the motor to induce reciprocation of the guard relative to the blade upon activation of the motor. A blade is recessed within the guard to expose a cutting edge of the blade between the pockets. The pockets engage tissue. A treatment tip is at a distal end of the guard. The treatment tip connects to an energy source. The treatment tip treats tissue upon activation of the treatment tip.

G06F 3/0481
A61B 18/12

Abstract:

A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to treat tissue to create lesions without ablating the tissue. The system includes a first treatment device having a plurality of electrodes. The electrodes are maintained in axial alignment and fixed radial spacing in retracted and extended positions. The device includes a basket having a plurality of arms. The arms are maintained in a fixed radial spacing in the collapsed position of the basket.

Abstract:

A device for applying radiofrequency energy for sphincter treatment comprising a flexible outer tube, an expandable basket having a plurality of arms movable from a collapsed position to an expanded position, and a plurality of electrodes movable with respect to the arms from a retracted position to an extended position. An advancer is slidably disposed within the outer tube to move the plurality of electrodes to the extended position. An actuator moves the advancer from a first position to a second position to advance the plurality of electrodes. An aspiration tube extends within the outer tube. An assembly includes an aspiration disabler having a first position to enable aspiration from a distal portion of the aspiration tube to a proximal portion and a second position to disable aspiration.
