US Patent:
2010023, Sep 16, 2010
Filed:
Oct 9, 2009
Appl. No.:
12/576826

International Classification:
A61F 2/06, C12N 5/02
US Classification:
600 36, 435395, 623 13, 623 144
Abstract:
The invention provides method of fabricating a scaffold comprising a fluidic network, including the steps of: (a) generating an initial vascular layer for enclosing the chamber and providing fluid to the cells, the initial vascular layer having a network of channels for fluid; (b) translating the initial vascular layer into a model for fluid dynamics analysis; (c) analyzing the initial vascular layer based on desired parameters selected from the group consisting of a characteristic of a specific fluid, an input pressure, an output pressure, an overall flow rate and combinations thereof to determine sheer stress and velocity within the network of channels; (d) measuring the sheer stress and the velocity and comparing the obtained values to predetermined values; (e) determining if either of the shear stress or the velocity are greater than or less than the predetermined values, and (f) optionally modifying the initial vascular layer and repeating steps (b)-(e). The invention also provides compositions comprising a vascular layer for use in tissue lamina as well as a medical devices having a vascular layer and kits.

System And Method For In Vitro Blood Vessel Modeling
US Patent:
2011005, Mar 3, 2011
Filed:
Feb 11, 2009
Appl. No.:
12/866968
Inventors:
David M. Hoganson - Boston MA, US
Joseph P. Vacanti - Boston MA, US
Joseph P. Vacanti - Boston MA, US
International Classification:
C12Q 1/02, G09B 23/30
US Classification:
435 29, 434272
Abstract:
The present invention provides an in vitro blood vessel model for investigation of drug induced vascular injury and other vascular pathologies. The in vitro blood vessel model provides two channels separated by a porous membrane that is coated on one side by an endothelial cell layer and is coated on the other side by a smooth muscle cell layer, wherein said model is susceptible to the extravasation of red blood cells across said porous membrane due to drug induced vascular injury.

US Patent:
2008009, Apr 24, 2008

Appl. No.:
11/465668
Inventors:
David M. Hoganson - Boston MA, US
Ravi K. Veeraswamy - Atlanta GA, US
Ravi K. Veeraswamy - Atlanta GA, US
International Classification:
A61M 25/09
US Classification:
604528
Abstract:
A device for accessing a vessel, duct or lumen, comprising a guidewire having a proximal end and a distal end, and at least one projection that extends from said guidewire at or near the distal end of the guidewire. When the guidewire is placed into the vessel, duct or lumen containing a flowing fluid, the drag on the guidewire is greater when the fluid is flowing from the proximal to distal end of the guidewire than it is when it is flowing distally-to-proximally, thereby helping to direct the guidewire. The device is particularly useful in crossing a narrowing in the vessel, duct or lumen, such as may occur in blood vessels containing a stenosis, such as due to atherosclerosis.
