International Classification:

G02B 626

US Classification:

385 31, 606 15, 606 16

Abstract:

A novel optical fiber, and a method for its production, having a diffuser portion and continuous unitarily-constructed outer sleeve, which is adapted for the transmission of light to a treatment locale.

Inventors:

Gregory J. Bakos - Mason OH, US
Kurt R. Bally - Maineville OH, US

Assignee:

Ethicon Endo-Surgery, Inc. - Cincinnati OH

International Classification:

A61M 29/00

US Classification:

606190

Abstract:

A medical device for use with an endoscope is provided. The medical device can include a tube with a first channel for receiving the endoscope. A transparent segment can extend from the distal end of the tube, and the transparent segment can have a first outer diameter sized for providing dilation of a portion of a body lumen. The medical device can also include a tapered tip attached to the distal end of the transparent segment that narrows from the first outer diameter to a distal terminating end. The endoscope is used to view the body lumen through the medical device while in use to dilate a stricture under direct visualization.

US Classification:

600104, 600121, 600122, 600123, 600153

Abstract:

A guide system for use with an endoscope, and a method of use is disclosed. The guide system can include a track, in the form of a rail, and a mating member for engaging the rail. The guide system can also include an accessory, such as an accessory guide tube through which a medical instrument can be carried external of the endoscope. An end cap can be provided to support the track relative to the distal end of the endoscope.

Assignee:

Ethicon Endo-Surgery, Inc. - Cincinnati OH

International Classification:

A61M 25/00

US Classification:

604528, 606 41

Abstract:

A first medical instrument includes a flexible catheter and a medical guidewire extendable beyond a distal end of the catheter. The medical guidewire has first and second segments, wherein the bending moment of inertia of the first segment is less than the bending moment of inertia of the second segment. A second medical instrument includes a flexible catheter, a mechanized guidewire assembly, and a medical guidewire extendable beyond a distal end of the catheter. The medical guidewire has an exterior surface including a repetitive series of spaced-apart surface elevation features. One example of surface elevation features is external threads. The spaced-apart surface elevation features are adapted for operable engagement with the mechanized guidewire drive assembly.

Assignee:

Ethicon Endo-Surgery, Inc. - Cincinnati OH

International Classification:

A61M 25/01

US Classification:

604528, 600118

Abstract:

A first medical instrument includes a flexible catheter having a distal end which has a substantially bullet-nose shape, which is insertable into a body lumen of a patient, and which has at least one guidewire passageway opening. The first medical instrument also includes a medical guidewire having a working portion extendable beyond the at-least-one guidewire passageway opening. A second medical instrument includes a flexible catheter, a medical guidewire having a working portion extendable beyond the distal end of the catheter, and at least one wire length counter which is operably connectable to the medical guidewire to measure a length of the working portion being extended beyond the distal end of the catheter. A third medical instrument includes a flexible catheter, a medical guidewire, and a force/torque-limiting clutch operatively connectable to the medical guidewire.

Abstract:

A first medical instrument includes a flexible catheter and a medical guidewire extendable beyond a distal end of the catheter. The catheter is adapted to slidably receive a rail-coupling portion of an adjunct medical device. The medical guidewire has first and second segments, wherein the bending moment of inertia of the first segment is less than the bending moment of inertia of the second segment. A second medical instrument includes a flexible catheter, a mechanized guidewire assembly, and a medical guidewire extendable beyond a distal end of the catheter. The catheter is adapted to slidably receive a rail-coupling portion of an adjunct medical device. The medical guidewire has an exterior surface including a repetitive series of spaced-apart surface elevation features. One example of surface elevation features is external threads.
