Abstract
An ovum collection device (20) includes a handle (4) and a collection needle (3) extending from the handle. The collection needle has a sharpened tip (44) for insertion into a follicle of an ovary. A collection duct (5) in fluid communication with the collection needle extends from the handle to a collection bottle (6). A heating arrangement (14) is used to maintain the collection needle at a selected temperature to prevent damage to an oocyte. The heating arrangement may be associated with a needle guide (72) on an ultrasonic probe such as a transvaginal ultrasonic probe (70).
Claims21
An oocyte retrieval device including an aspiration needle, the oocyte retrieval device including an arrangement to maintain at least a part of the aspiration needle at or near a selected temperature.
An ovum collection device including a handle, a collection needle extending from the handle, the collection needle having a sharpened tip for insertion into a follicle of an ovary, a collection duct in fluid communication with the collection needle and extending from the handle to a collection bottle and a heating arrangement to maintain the collection needle at a selected temperature.
An aspiration and flushing needle assembly having separable flushing and aspiration assemblies, the flushing assembly having a flushing needle connectable to a source of flushing liquid and the aspiration assembly having an aspiration needle connectable to an aspiration arrangement, the flushing and aspiration needle assemblies being connectable for use with the aspiration needle extending coaxially within the flushing needle to a distal end thereof and a heating arrangement to maintain at least part of the assembly at a selected temperature.
A transvaginal ultrasonic probe comprising an elongate body, an ultrasonic transmitter and receiver arrangement at a distal end thereof, a groove extending along the elongate body, the groove being adapted to receive in use an aspiration needle for oocyte recovery, the groove including heating means adapted to maintain an aspiration needle when received in the groove at a selected temperature.
