Definitions

  • This invention relates to surgical tools. More particularly, it relates to a modified Amplatz delivery system having applications in fetal therapy.
  • Endoscopic fetal surgery requires that an opening be made in the myometrium, chorion, and amnion with a trocar. Detachment of the fetal membranes from the uterine wall can occur during such surgery. Accordingly, there is a need for a device that prevents fetal membrane detachment in patients undergoing endoscopic fetal surgery.
  • the novel VSD-fetal membrane attachment device for preventing fetal membrane detachment in patients undergoing endoscopic fetal surgery includes a delivery plunger, a trocar sheath, a delivery sheath, and a VSD device that is deployed from the delivery sheath by retracting the delivery sheath while maintaining the delivery plunger against movement. More particularly, the novel VSD-fetal membrane attachment device includes a delivery plunger, a trocar sheath having a lumen, a delivery sheath having a lumen and said delivery sheath ensleeved within a lumen of the trocar, and a VSD device ensleeved within the lumen of the delivery sheath
  • the VSD device has a waist, a leading disc at a first end of the waist and a trailing disc at a second end of the waist.
  • the leading disc and the trailing disc are radially contracted when the VSD device is ensleeved within the lumen of the delivery sheath.
  • the leading disc and the trailing disc are radially expanded under an inherent bias when the VSD device is expelled from the lumen of the delivery sheath.
  • the leading disc is adapted to overlie an amnion when the leading disc is radially expanded.
  • the trailing disc is adapted to overlie a myometrium when the trailing disc is radially expanded.
  • the device prevents fetal membrane detachment in patients undergoing endoscopic fetal surgery. Moreover, the device facilitates use of multiple ports, larger ports, or multiple, larger ports thereby allowing performance of more complicated endoscopic fetal procedures.
  • the VSD device is expelled from the lumen of the delivery sheath when the delivery plunger is held against movement and the delivery sheath is retracted in a proximal-to-distal direction.
  • the delivery plunger has an externally-threaded leading end.
  • the trailing disc has an internally threaded aperture that is engaged by the delivery plunger leading end. The delivery plunger leading end is disengaged from the trailing disc after the trailing disc is radially expanded.
  • a valve closes the internally threaded aperture when the delivery plunger leading end is disengaged from the internally threaded aperture.
  • Fig. 1 is a perspective view of a novel VSD-fetal membrane attachment device prior to deployment of the VSD device
  • Fig. 2 is a perspective view of the apparatus depicted in Fig. 1 when the VSD device is partially deployed;
  • Fig. 3 is a perspective view of the apparatus depicted in Fig. 3 when the VSD device is fully deployed;
  • a novel VSD-fetal membrane attachment device is denoted as a whole by the reference numeral 10.
  • Device 10 prevents fetal membrane detachment in patients undergoing endoscopic fetal surgery. Use of this device facilitates the use of multiple ports, larger ports, or multiple, larger ports thereby allowing performance of more complicated endoscopic fetal procedures.
  • Device 10 includes delivery plunger 12, trocar sheath 14, delivery sheath 16, and VSD device 18.
  • Amnion 20 is a thin membrane forming a closed sac containing amniotic fluid about the fetus.
  • Chorion 22 is an outer embryonic membrane associated with the formation of the placenta.
  • Myometrium 24 is the smooth muscular wall of the uterus.
  • VSD device 18 is partially deployed in Fig. 2 and fully deployed in Fig. 3.
  • Leading disc 18b and waist 18c are visible in Fig. 2 and trailing disc 18a is visible in Fig. 3.
  • the leading and trailing discs are radially contracted when housed within the lumen of the delivery sheath and said discs are radially expanded when expelled from said lumen.
  • Delivery plunger 12 performs the function of pushing VSD device 18 from the lumen of delivery sheath 16. More particularly, the delivery sheath is retracted while plunger 12 is held in place. The discs 18a, 18b of VSD device 18 deploy under their inherent bias upon exiting said delivery sheath lumen.
  • Delivery plunger 12 is retracted after full deployment of the VSD device by a rotational motion 12a as indicated in Fig. 3. More particularly, the leading end of delivery plunger 12 is externally threaded and trailing disc 18a has a central aperture that is internally threaded for screwthreaded engagement with the leading end of the delivery plunger. This screwthreaded engagement ensures that the delivery plunger and VSD device 18 will remain connected to one another until the VSD device is fully deployed. After trailing disc 18a is radially expanded, the physician unscrews the delivery plunger from the internally threaded central aperture. A valve then closes the internally threaded central aperture.

Abstract

L'invention concerne un dispositif d'attache de membrane VSD-fœtale pour empêcher le détachement de membranes fœtales chez des patients subissant une chirurgie fœtale endoscopique comprenant un plongeur d'administration, une gaine de trocart, une gaine d'administration et un dispositif VSD déployé à partir de la gaine d'administration en rétractant la gaine d'administration tout en maintenant le plongeur d'administration en place. Le VSD a des disques radialement contractés lorsqu'il est logé dans la lumière de la gaine d'administration qui se dilatent radialement sous leur sollicitation inhérente lorsque le VSD est déployé depuis la lumière de la gaine d'administration. Un disque d'attaque recouvre l'amnios et un disque de fuite recouvre le myomètre.
