Patent number: 7169548Abstract: Methods and apparatus are disclosed for processing sperm cells to accomplish preservation for future use while minimizing the adverse effects of such preservation. Sperm cells may be collected from a male animal and subjected to a first preservation step, including potentially a first cryopreservation step. Preserved sperm may then be revived, including potentially by thawing, and treated by any of various processing steps to mitigate the adverse effects of preservation. Treated sperm may then be subjected to a second preservation step, including potentially a second cryopreservation step, perhaps enabling a delayed use of the sperm at a future time.Type: GrantFiled: January 9, 2003Date of Patent: January 30, 2007Assignee: XY, Inc.Inventors: William Maxwell Chisholm Maxwell, Fiona Kate Hollinshead, Justine Kellie O'Brien, Gareth Evans

Patent number: 6819411Abstract: Various optical apparatus provide a source of parallel light (7, 75). The parallel light (7, 75) is generally achieved by directing an incident beam at the apex of a prism (1, 22, 24, 26, 28). The prism may have varying configurations. One configuration has a forward conical face (24). Another configuration has a pyramidal forward end (22). Other configurations are also disclosed. The application also discloses the use of reflectors (20, 78, 216, 316, 400) having internal reflective surfaces shaped as three-dimensional figures of revolution, for example paraboloid or ellipsoid. The reflectors (20, 78, 216, 316) focus light incident onto the reflectors at one or more foci (F, 220, 320, 420). The reflectors may be used in combination with the optical apparatus including the prisms (1, 22, 24, 26, 28). The reflectors (20, 78, 216, 316) may be used in flow cytometers for focussing light at a sample stream (237, 337) passing through the focus (F, 220, 320, 420) of the reflector (20, 78, 216, 316).Type: GrantFiled: September 17, 1999Date of Patent: November 16, 2004Assignee: XY, Inc.Inventors: Johnathan Sharpe, Peter Niven Schaare

Patent number: 6782768Abstract: An improved nozzle system for a flow cytometer and accompanying methods have been invented for a high efficiency orientation and sorting process of a flat sample and dedicates items such as equine or bovine sperm cells. This improved nozzle system comprises a nozzle with a novel interior surface geometry that can both gently accelerate the cells and can include an elliptical-like, single torsional interior surface element within the nozzle, i.e., a single torsional orientation nozzle. The elliptical-like, single torsional interior surface element may have a laminar flow surface and may produce the simplest flow path for applying minimal forces which act in either an accelerative nature or orienting hydrodynamic forces, namely, the single torsional orientation forces, to orient a flat sample such as animal sperm cells into a proper direction for an analyzing and efficiently sorting process in clinical use, for research and for the animal insemination industry.Type: GrantFiled: August 12, 2003Date of Patent: August 31, 2004Assignee: XY, Inc.Inventors: Kris S.

Patent number: 6746873Abstract: A flow cytometry system is disclosed for oscillating the exterior of a flow cytometer nozzle. Oscillating the exterior of a flow cytometer nozzle at selected oscillations or a sweeping range of oscillations disintegrates particles and gas entrapped within the flow cytometer nozzle. Adherents absorbed to the exterior of the flow cytometer nozzle may also be removed. An energy source (1) serves to generate a selected oscillation or range of oscillations. The energy source (1) is connected to a flexible transfer element (2) which conducts the electrical signals to an oscillation system (3). The oscillation system (3) turns the electrical energy from the energy source (1) into mechanical oscillations and is connected to a portable device (4) which disintegrates particles, dislocates gas within the flow cytometer nozzle and cleans the exterior of the flow cytometer aperture.Type: GrantFiled: September 18, 2000Date of Patent: June 8, 2004Assignees: XY, Inc., DakoCytomation Colorado, Inc., Colorado State University Research FoundationInventors: Kristopher S.

Publication number: 20030157475Abstract: The present invention provides a method of cryopreserving sperm that have been selected for a specific characteristic. In a preferred embodiment, the method is employed to freeze sex-selected sperm. Although the cryopreservation method of the invention can be used to freeze sperm selected by any number of selection methods, selection using flow cytometry is preferred. The present invention also provides a frozen sperm sample that has been selected for a particular characteristic, such as sex-type. In preferred embodiments, the frozen sperm sample includes mammalian sperm, such as, for example, human, bovine, equine, porcine, ovine, elk, or bison sperm. The frozen selected sperm sample can be used in a variety of applications. In particular, the sample can be thawed and used for fertilization. Accordingly, the invention also includes a method of using the frozen selected sperm sample for artificial insemination or in vitro fertilization.Type: ApplicationFiled: October 7, 2002Publication date: August 21, 2003Applicant: XY, Inc.Inventor: John L.
