Definitions
- the present invention refers to an intrauterine placement expander catheter with anatomical characteristics adaptable to the different morphologies that the uterine organ presents in its interior cavities and that efficiently allows the dilation and separation of the internal walls of the uterine cavity, to fulfill the double mission: on the one hand, to separate the uterine walls, in order to prevent intrauterine adhesions, that is, thus avoiding their coaptation and, on the other hand, it allows compression of the uterine walls, acting as a hemostatic factor.
- the uterine cavity is about what is defined in medicine as a virtual cavity. This means that the uterine walls, in the absence of artificial separation between them, are in close contact. This coaptation of the uterine walls can lead to the formation of adhesions or scars that occur between opposite faces in cases in which an internal injury or aggression occurs, as occurs in cases of intrauterine surgery.
- the physical or barrier methods are among the most used and among the most effective, as demonstrated by Lin's comparative studies (Lin, X, Wei, M., Li, TC, Huang, Q. , Huang, D., Zhou, F., & Zhang, S. (2013).
- This type of catheters materialize in a kind of inflatable body, in which a series of extracorporeal external tubes participate through which, once the device is implanted, it can swell, defining a single central drainage channel.
- the problem with this type of device lies in its design (poorly adapted to uterine anatomy), in the difficulty of placement and in the poor drainage of bleeding accumulated inside the cavity.
- a similar situation occurs in the case of the invention patent WO2016074647, in which a kind of inflatable balloon intended to separate the uterine walls is provided, and balloons for fixation to the cervix, with respective inflation valves, also presenting the same problems of the difficulty in the placement and the scarce drainage of the accumulated bleeding inside the cavity, just having an internal drainage.
- a kind of inflatable balloon is also provided, also with an internal drain, in which a single internal inflation chamber in the shape of a triangle participates, with the same limitations from the point of view of problems related to the difficulty of placement and the scarce drainage of the accumulated bleeding inside the cavity, since only an internal drain is available.
- the intrauterine expander device that is recommended solves transvaginal placement failures and internal positioning, in addition to avoiding discomfort in patients due to overinflation of the walls, presenting substantial improvements in its multiple drainage channels for removal extra pressures due to fluid accumulation and obstruction of the main drainage channel, in addition to the lack of extracorporeal external tubes.
- the device of the invention has the particularity that it materializes from an inflatable main body, which has a tip-shaped configuration of inverted lance with a blunt tip in its central area, coinciding with a central drainage channel with drainage through a central tube, with the particularity that said body is made up of several individual, and superimposed, inflation chambers that determine two flexible lateral wings with rounded edges that initially fold, occupying a minimum volume within an inserter device, of configuration tubular and open, like a sheath, which significantly facilitates the implantation of the device and its passage through the cervix, ensuring the extreme points of depth in the insertion device introduction, that is, the correct placement inside the uterus in the ends that comprise its anatomy, passing through the neck to the bottom of the space that comprises the uterine cavity itself, being able to easily withdraw coaxially from the device once it is placed in the working area by means of an internal disposable pusher, also with the inserter device, which can be
- the main and inflatable body will present an ergonomic configuration with adaptation variables to the different morphologies of the organ, defining in its inflation a section of warped contour both on its two major faces and on its two minor faces, that determine in their support on the walls of the uterus, a plurality of additional drainage channels to the central drainage channel.
- a quadruple lateral and central double inflation chamber participates in the main body to recreate a greater number of drainage channels; apart from the unified central, thus covering all the angles of fluid withdrawal by intra-mural secretion, thus avoiding overpressures and adhesions of epithelial tissue.
- said main body is finished off inferiorly in a triple balloon attached to the cervix, with discontinuous lateral fixation rings and drainage channels, to avoid its dislocation and possible withdrawals during the phases of muscular contraction.
- a central conduit is added for the evacuation of internal liquids, thus defining seven drainage channels, one central, two upper, two lower and two lateral.
- the special configuration of the device means that it has a smaller size and weight, without external forms of plastic in the shape of a tip. Likewise, having different inflation chambers allows partial and irregular inflation for greater adaptation to intracavitary dysmorphias.
- the main body within the sheath or inserter device As for the way of folding the main body within the sheath or inserter device, it will be folded within it in order that it, due to its own configuration as a tree, can be deployed in the most efficient way. , adapting to the side walls of the uterine cavity.
- the morphology of the device deployed in the form of a lateral float with internal channels for channeling and the front inflation limiter allow greater adaptability to intrauterine cavities, as well as a greater volume of separation, without discomfort of the placement, to avoid possible total or partial adhesions that involve a subsequent re-intervention by the gynecologist; discomforts added to the phases of muscular contraction of the uterus in the recovery stage, such as those produced by involuntary contractions.
- Figure 1. Shows an upper side perspective view of an intrauterine expander device made according to the object of the present invention, in an unfolded arrangement but without being fully inflated.
- Figure 2. Shows a detail in a different perspective of the whole of the previous figure.
- Figure 3. Shows the device of figure 1 according to another perspective.
- Figure 4. Shows a perspective view of the device of the previous figures duly inflated.
- Figure 5.- Finally shows a sectional view of the device, inserted into an applicator inserter device for the introduction of the assembly into the uterus.
- the intrauterine expander device that is recommended is constituted from an inflatable main body (1), which has a configuration in the form of an inverted spearhead, with rounded edges, in which superiorly defines a central drainage channel (2) towards a central tube (3), central channel (2) that presents its end partially blocked by a blunt tip (4), so that said main inflatable body ( 1) It is made up of several individual inflation chambers, that determine two flexible lateral wings (5) with rounded edges that initially fold, occupying a minimum volume within an inserter device (6), the one shown in figure 5, with a tubular configuration and a rounded and open tip, as sheath, which significantly facilitates the implantation of the device and its passage through the cervix.
- This inserter device (6) can be easily removed coaxially from the main device by fractioning it, once it is placed in the working area, next to the internal pusher element (11).
- the device can be easily deployed by inflating its chambers, for which they are associated with small inflation tubes (7) that run internally to the central drain tube (3), presenting a greater length than this , so that at their lower extremity, they adopt a spiral configuration, allowing them to retract once the device has been adapted to the patient's physiognomy, ending at said ends in the corresponding non-return valves, not shown in the figures.
- the main body (1) will present an inflatable and ergonomic configuration, adaptable to the different morphologies of the organ, with the special feature of that in its swelling a section of warped contour is defined both on its two major faces and on its two minor faces, which determine in its support on the walls of the uterus, a plurality of additional drainage ducts or channels (8) to the central drainage channel (2) and the central tube (3).
- a quadruple lateral and double central inflation chamber participates in the main body to recreate a greater number of drainage channels (8).
- a triple balloon fixation to the cervix (9) is established, with discontinuous lateral fixation rings (10) and drainage canalization, to avoid its dislocation and possible withdrawals during the phases of muscular contraction.
- the multi-camera configuration allows for further expansion along the side edges.
