Patent CA-3033786-A1 (CA)
Title: Port fixation device
Inventor: CIAMPINI FABIO
IPC: A61M39/02
Filed: 2019-02-14
Abstract: A port fixation device is disclosed and includes a body portion and a plug. The body portion includes a circular portion, a first tab, and a second tab. The circular portion defines an aperture which is configured to allow a surgical access port to extend therethrough. The first tab and the second tab are disposed in mechanical cooperation with the circular portion. Movement of the first tab with respect to the second tab from a first position to a second position causes a diameter of the aperture to change from a first size to a second size. The first size is smaller than the second size, and the first position of the first' tab is its rest position. The plug is disposed in mechanical engagement with the body portion, and has sufficient elasticity to remain engaged with the body portion when the first tab is in the first position and in the second position.

Patent CA-3040274-A1 (CA)
Inventor: BURNS ELIZABETH
IPC: C04B24/00
Filed: 2017-10-11
Abstract: The present invention relates to very high workable yet controllable concrete mix design, admixture composition, and process for placing concrete. The mix design relates to particular aggregate/cement ratios and types which are characteristic of ready mix concrete (RMC), which provide high fluidity reminiscent of self-consolidating concrete (SCC), and which provides advantages over both RMC and SCC in terms of ease and speed in placement and finishability at the construction site placement zone, regardless of whether into a horizontal formwork (e.g., for slabs, floors) or into vertical formwork (e.g., for blocks, walls, columns, etc.), without loss of control and without generating high risks of segregation even when small amounts of water are added at the size to facilitate finishing of the concrete surface. An inventive admixture combination which enables this unique design involves two different polycarboxylate comb polymers in combination with two specific viscosity modifying agents, and this combination provides highly workable concrete to be placed in a controlled, efficient manner.
