Filed:

Apr 18, 2008

Appl. No.:

12/106196

Inventors:

Janelle Anderson - New York NY, US
Steven F. Bierman - Del Mar CA, US
Wei Huang - San Diego CA, US
Richard A. Pluth - San Diego CA, US

Assignee:

Access Scientific, Inc. - San Diego CA

International Classification:

A61M 5/178

US Classification:

60416403, 60416405, 6041641, 60416413, 60416502

Abstract:

An access device places a medical article within a body space of a patient. The device has a needle that includes an elongated body and a needle hub. The device further includes a dilator disposed on and slideable along the elongated body of the needle and a medical article. The medical article is disposed on and slideable along the dilator. A track extends in a proximal direction from the dilator. The needle hub slides along at least a portion of the track between a first position and a second position. The device further includes a locking mechanism operably disposed between the track and the needle hub so as to inhibit further axial movement of the needle in the proximal direction when the needle hub is in the second position.

US Classification:

60416401

Abstract:

An access device places a medical article within a body space of a patient. The device has a needle that includes an elongated body, a side fenestration on the elongated body, and a needle hub. The device further includes a dilator disposed on and slideable along the elongated body of the needle and a medical article. The medical article is disposed on and slideable along the dilator. The dilator and the needle form one or more spaces in communication with the side fenestration. At least portions of the dilator and the medical article are configured so as to allow visual determination of the presence of a bodily fluid within the space. The outer surface of the needle and the inner surface of the dilator can include a surfactant. Further, at least one of the needle and dilator can further comprise a vent in communication with the space that allows for the escape of air from the space and inhibits the escape of the bodily fluid from the space.

Filed:

Nov 3, 2015

Appl. No.:

14/931543

Inventors:

- Princeton NJ, US
Wei Huang - Plainsboro NJ, US

International Classification:

H01L 27/146

Abstract:

A photodiode includes a cap layer defining an inboard side and an outboard side. A plurality of pixels are formed in the cap layer extending from the inboard side to the outboard side. At least a portion of the cap layer is defined in between the pixels. A metal barrier is in between the pixels and is operatively connected to the inboard side of the cap layer in between the pixels to reflect light rays into the cap layer reducing the leakage of photons between the pixels.

H01L 31/0216

Abstract:

A photodiode has an absorption layer and a cap layer operatively connected to the absorption layer. A pixel is formed in the cap layer and extends into the absorption layer to receive charge generated from photons therefrom. The pixel defines an annular diffused area to reduce dark current and capacitance. A photodetector includes the photodiode. The photodiode includes includes an array of pixels formed in the cap layer. At least one of the pixels extends into the absorption layer to receive charge generated from photons therefrom. At least one of the pixels defines an annular diffused area to reduce dark current and capacitance.
