Patent CA-2184900-C (CA)
Inventor: DOIRON DANIEL R
IPC: G02B6/00
Filed: 1993-10-07
Granted: 2003-12-30
Abstract: Pointe flexible (10), destinée à un cathéter à usage médical, apte à transmettre la lumière et dont les dimensions lui permettent de passer à travers des éléments tubulaires extrêmement petits. La pointe flexible, qui est de préférence composée d'un élastomère en silicone transparent (13), est fixée à l'extrémité d'une fibre optique classique. Selon un mode préféré de réalisation, la pointe comprend une âme (11) en silicone, entourée d'une gaine (12) dont l'indice de réfraction est inférieure à celle de l'âme (11), permettant ainsi une réflexion interne. La pointe flexible est pourvue d'une enveloppe externe (13) qui a deux fonctions: (a) elle confère une intégrité structurale à la pointe; et (b) elle sert à renforcer la liaison entre la pointe flexible et la fibre optique contre laquelle elle vient en butée. La pointe (10) permet d'apporter une intensité de lumière comparable à celle d'une fibre de verre de grande dimension et d'un diamètre d'âme équivalent mais présente une flexibilité supérieure par rapport à une telle fibre. Elle est ainsi suffisamment flexible pour pénétrer dans des éléments tubulaires sinueux tout en retenant les aptitudes de transmission de lumière des guides d'ondes optiques en fibre de verre relativement peu flexibles et de même diamètre.

Title: Methods for harvesting adipose tissue containing autologous microvascular endothelial cells
Inventor: HU CAN B
IPC: A61F2/06
Filed: 1995-06-29
Granted: 2006-06-06
Abstract: Disclosed herein are methods for harvesting adipose tissue so as to preserve an increased population of viable microvascular endothelial cells. Adipose tissue containing microvascular endothelial cells is harvested using a collection apparatus incorporating an elongate cannula having apertures with tissue cutting edges. A sub-ambient pressure is applied to a lumen in the cannula to draw the adipose tissue through the aperture where it is then severed using the cutting edge to disrupt the connective adipose matrix. This harvesting provides a cleaner, more homogeneous sample of adipose tissue, thereby increasing the population of viable microvascular endothelial cells obtained through further processing. Rapid and easy methods for the further homogenization of the harvested adipose tissue are also disclosed.
