Filed:

Jul 21, 2006

Appl. No.:

11/996450

Inventors:

Trent Deem - Bountiful UT, US
Phil Ligrani - Oxford, GB
Bradley C. Hansen - La Jolla CA, US

International Classification:

A61K 9/22

US Classification:

6048921

Abstract:

A high pressure osmotic dispense pump () having a substantially continuous delivery rate and extended delivery times is described and disclosed. The dispense pump () includes a semi-permeable membrane () which is substantially free of distortions and lateral stretching stresses. The membrane housing () and configuration of the present invention allows for consistent and accurate flow rates at the micro-liter level and improved control of the surface area of the semi-permeable membrane (). This osmotic pump () also includes optional methods for activating and deactivating the osmotic process and/or controlling flow rates. Along with these features, the pump can be amplified or modulated to increase the dispense rate and/or adjust the flow rate during operation.

US Classification:

210661, 210109, 210265, 210289, 210 86

Abstract:

An apparatus and method for removing soluble and particulate matter from a liquid. The liquid is introduced into a lower section of the apparatus and develops an upward helical flow. The vertical component of the helical flow is decreased in a conical section. The liquid then passes through fluidized bed media where an interaction between the liquid and the fluidized bed media can occur. The liquid may be passed through a system that removes suspended solids.

US Classification:

606130, 600407, 600425, 600410

Abstract:

Integrated surgical systems and methods for using same are provided that can receive scanned images and produce a three dimensional model from the images. Based at least in pan on the three dimensional model, a processor generates code defining an optimized tool path, which is sent to a surgical machining system that can machine the desired portion of the patient. In one exemplary aspect, the integrated system operates in a clearly defined and pre-programmed manner with no necessity for in-situ sensory or guidance feedback.
