Title: Brush electrode and method for ablation
Inventor: THAO CHOU
IPC: A61B18/14
Filed: 2005-01-14
Abstract: A brush electrode (e.g., 10) and a method for using the brush electrode for tissue ablation are disclosed. The brush electrode comprises a plurality of flexible filaments or bristles (e.g., 26) for applying ablative energy to target tissue (46) during the formation of spot or continuous linear lesions.  Interstitial spaces (156) are defined among the filaments of the brush electrode, and the interstitial spaces are adapted to direct conductive or nonconductive fluid (34), when present, toward the distal ends of the brush filaments. The brush electrode facilitates electrode tissue contact in target tissue having flat or contoured surfaces.

Title: Extraction screwdriver
Inventor: RATHBUN DAVID SAWYER
IPC: A61B17/86
Filed: 2005-03-22
Abstract: A bone fastener removal tool including an inner shaft axially engaging a bone fastener, a drive shaft allowing the fastener to be rotated using the tool, and an internally threaded outer sleeve, in combination with the drive shaft, allowing for a controlled removal of the fastener from the bone plate and bone. The internal threads of the outer sleeve engage external threads on the drive shaft such that rotating the drive shaft while maintaining the outer sleeve fixed causes the drive shaft to translate with respect to the sleeve.  Thus, when a fastener is axially engaged with the drive shaft, a controlled removal of the fastener from the bone and bone plate is accomplished by rotating the drive shaft with respect to the outer sleeve. No pulling on the fastener is necessary. A method of using the tool is also provided.

Title: Method of making electrodes for electrochemical fuel cells
Inventor: BAI KYOUNG J
IPC: H01M4/04
Filed: 2005-08-17
Abstract: In preparing a fluid diffusion electrode, typical methods include applying a catalyst ink to a fluid diffusion layer, drying the catalyst ink and hot-pressing the coated fluid diffusion layer to produce a fluid diffusion electrode. In the present application, unexpected improvements in the smoothness of the resulting electrode have been observed by drying the catalyst ink during compaction. To assist with drying the catalyst layer, the compacting step may be performed at elevated temperatures. In some embodiments, a release sheet may be applied to the catalyst layer prior to compaction. In addition or alternatively, partial drying of the catalyst layer may occur prior to compaction.

Title: Corrugated pipe made of thermoplastic plastic
Inventor: KELLNER MICHAEL
IPC: F16L9/128
Filed: 2007-04-13
Abstract: The present invention relates to a corrugated pipe (1) made of thermoplastic plastic, which includes an inner pipe (2) and a corrugated outer pipe (3) connected thereto, wherein the profile of the outer pipe comprises first sections (4) with a first average diameter, second sections (5) with a second average diameter greater than the first average diameter, and, disposed therebetween, flanks (6) that connect the first sections (4) to the respective adjacent second sections (5). The geometric relationships of the inventive corrugated pipe (1) are designed to yield not only high rigidity against pressure forces acting on the corrugated pipe in the radial direction and high flexibility with regard to bending of the corrugated pipe transversely to its longitudinal axis, but also, at the same time, a low weight in comparison to conventional corrugated pipes. This reduces the consumption of plastic during production and makes the corrugated pipe easier to handle when it is being laid.   (Fig. 3)
