  • Publication number: 20200139099
    Abstract: The invention pertains to apparatuses, means and methods to promote uptake of fluids into a reservoir of an implantable drug delivery system though a porous membrane. Embodiments of the invention promote fluid uptake by creating a pressure differential between the reservoir of the drug delivery device and the environment of the device after implantation, for instance a subcutaneous pocket.

  • Publication number: 20200060664
    Abstract: A surgical device for suturing body lumen is described, as well as methods for suturing tissue employing the surgical device. The device can include a body having a shaft and a foot for insertion into an opening in a body lumen. The device can include tissue ports between configured to receive tissue surrounding the opening in the body lumen. The foot can include a suture secured to needle capture devices. The device can include needles that can be advanced through tissue and into the needle capture devices. The needle capture devices can then be withdrawn, thereby harvesting the suture, which can then be used to close the opening in the body lumen.

  • Publication number: 20190209162
    Abstract: A closure device for closing an opening in tissue is provided. The closure device includes an elongate member through which needles may be deployed. The closure device also includes a closure element having a foot portion and a needle guide portion. The foot portion and the needle guide portion are each movable between a delivery configuration and a deployed configuration. The foot portion includes cuffs removably mounted thereon and having sutures connected therebetween. The needle guide portion includes needle guide apertures that guide the needles to the cuffs. The needles securely engage the cuffs and draw the cuffs and suture through the lumen wall so that the opening in the lumen wall can be closed with the sutures.

  • Publication number: 20190091140
    Abstract: Embodiments of the invention include devices, compositions and methods for the controlled release of therapeutic substances, such as drugs. Control over the rate of release of the therapeutic substances from the devices is achieved by the use of nanoporous membranes in which the pore size is matched to the molecular diameter of the therapeutic substances. Some embodiments of the invention achieve zero-order release by the use of membranes with a pore diameter that is more than five times the Stokes' diameter of the therapeutic substance released.
