Embodiment Construction

[0062] For the purpose of illustrating the invention, several embodiments of the invention are shown in the drawings. However, it should be understood by those of ordinary skill in the art that the invention is not limited to the precise arrangements and instrumentalities shown in the drawings and described below. Throughout the specification, similar components are denoted by the same reference numerals. Throughout the specification, the terms "distal" and "proximal" as used in connection with different components and parts of components refer to their spatial relationship with respect to the control unit.

[0063] figure 2 An IVF controller device according to a preferred embodiment of the present invention is schematically shown. The IVF controller (generally designated by reference numeral 10) generally includes a control unit 12, and an elongated flexible extension hose 14 designed to be compatible with, for example, figure 2 The intrauterine ovum catheter assembly i...

Abstract

The invention provides devices and methods for performing in vitro fertilization ("IVF") and maximizing successful fertilization rates by optimizing the fluid flow conditions under which zygotes are transferred from growth medium to the uterine wall. The apparatus has a control unit with an external port and an internal pump for creating positive and negative fluid pressure at the port. A flexible extension hose connects the port to an inter-uterine catheter assembly. The catheter assembly has an inner catheter and an outer sheath surrounding the inner catheter. The control unit includes a programmable microprocessor that accepts input commands and controls operation of the pump. Optionally, the control unit has remote control means for activating, de-activating, and reversing the flow of the pump. The control unit can be programmed to repeatedly provide the same aspiration and expulsion flow conditions through the catheter assembly. The control unit may also be programmed to provide a defined sequence of aspiration and expulsion fluid flow conditions through the catheter assembly. The control unit may include an internal memory that records the fluid flow conditions through the catheter assembly during each step of the IVF procedure. By recording the fluid conditions during an Gamma[nu]Tau procedure and counting the number of zygotes that successfully develop into embryos under those conditions, a statistical analysis is performed to determine the optimum fluid flow conditions for an IVF procedure.

Description

[0001] related application [0002] This application claims Provisional Patent Application No. 61 / 738,735, filed December 18, 2012, entitled "Method and Apparatus for Controlling In Vitro Fertilization," and Application No. 61, filed September 18, 2013 / 879,669, priority to provisional patent application entitled "Method and Apparatus for Controlling In Vitro Fertilization," both of which are incorporated herein by reference. technical field [0003] The present invention generally relates to new devices for performing in vitro fertilization (IVF) and new methods of performing IVF. More specifically, the present invention relates to methods and devices for extracting fertilized eggs from culture or growth medium, and implanting the fertilized eggs on the uterine wall of a patient. The present invention also relates to a method of maximizing the rate of successful fertilization by optimizing the state of fertilized eggs when they are transferred from the growth medium to the ...
