Embodiment Construction

[0048] figure 1 It is shown that the inflation system 10 may have one or more tubes. The system 10 may have a first tube 12a (also called an inner tube), a second tube 12b (also called an outer tube), and optionally other tubes (eg, three tubes, or more than three tubes). The second tube 12b and / or the system 10 may form part of the insertion catheter 8 . The first tube 12a may have a first tube inner wall and a first tube outer wall. The second tube 12b may have a second tube inner wall and a second tube outer wall. The first tube 12a may have a first tube proximal end and a first tube distal end. The second tube 12b may have a second tube proximal end and a second tube distal end. Catheter 8 may have a proximal catheter end and a distal catheter end. The first tube 12a and the second tube 12b may define a first lumen 14a and a second lumen 14b, respectively. For example, the inner wall of the first tube 12a may define a first lumen 14a and the inner wall of the second ...

Abstract

Methods and apparatuses for utilizing an integrated, automated aerating device for echogenicity are described. The aeration device can have a pressurized vessel to provide echogenic air bubbles independently of fluid delivered for sonohsyterosalpingography. The aeration device can selectively supply a gas in liquid during ultrasound and radiographic procedures for enhanced visualization of the uterine cavity and fallopian tubes.

Description

[0001] Matthew Thomas Urek [0002] Michael Paul Hartsfield [0003] Steven R. Butzky [0004] Cross References to Related Applications [0005] This application claims priority to US Provisional Application No. 62 / 302,194, filed March 2, 2016, which is hereby incorporated by reference in its entirety. Background technique [0006] In infertile patients, assessment of tubal patency is an early evaluation in the diagnostic workup of patients and couples. One diagnostic technique is the ultrasound assessment of tubal patency by injection of saline-air contrast, which utilizes air bubbles to provide echogenic confirmation of tubal patency. Existing tubal patency assessment systems utilize an inflation system that includes a venturi assembly to deliver echogenic air bubbles to enhance ultrasound visualization. These systems require the end user to supply the fluid at a flow rate that produces the necessary pressure drop and vacuum to create an aeration effect that pulls air bu...
