Patent number: 8690831Abstract: Devices and methods are provided for removing fluid from a surgical access device and/or from surgical instruments passed therethrough, and for preventing such fluid from accumulating. For example, in one embodiment, an exemplary device can include a body defining a working channel that is configured and sized to allow for passage of a surgical instrument therethrough. A number of seals can be disposed in the working channel so as to contact the inserted surgical instrument. One or more outlets can be oriented to direct gas, such as air or an insufflation gas, into the working channel so as to remove fluid on the seals, or other parts of the surgical access device, as well as the surgical instruments themselves. In some embodiments, constant flows of gases can be arranged to act as shields to help prevent fluid from accumulating on the surgical access device and/or surgical instruments.Type: GrantFiled: April 25, 2008Date of Patent: April 8, 2014Assignee: Ethicon Endo-Surgery, Inc.Inventor: Daniel H. Duke

Patent number: 8684974Abstract: A surgical access assembly including a base and an elongated member extending from the base. The bass defines a central axis and has an opening for receipt of a surgical instrument. The elongated member defines a passageway for passage of at least a portion of the surgical instrument and is adapted to assume a substantially rolled configuration in a normal unstressed condition thereof. When in the rolled configuration, the elongated member is rolled transverse to the central axis.Type: GrantFiled: January 28, 2013Date of Patent: April 1, 2014Assignee: Covidien LPInventor: Paul D. Richard

Patent number: 8684975Abstract: A surgical access port comprises a valve or instrument seal that separates the instrument contact function from the instrument conforming function. Embodiments of the instrument seal comprise in instrument contact element that extends through an opening in a compression element, thereby defining an instrument orifice that seals with an instrument extending therethrough. Embodiments of the instrument contact element comprise a non-distensible membrane or film, for example, as a tube or cylinder.Type: GrantFiled: March 14, 2012Date of Patent: April 1, 2014Assignee: Applied Medical Resources CorporationInventors: Jeremy J.

Publication number: 20140074032Abstract: An intravenous catheter inserter device comprising a catheter threader body on which is slidably attached a septum activator, a catheter threader, and a needle hub. Some embodiments further include a safety bar that is configured to assist in coordinating the movement of the various components of the device during a catheterization procedure. In general, the septum activator provides a pathway through a septum of a Luer adapter. The Luer adapter comprises a wedge seal that is configured to receive a base portion of a catheter that is inserted into the Luer adapter by the catheter threader. Accordingly, the device of the present invention simultaneously accesses the vasculature of a patient while assembling the catheter into the Luer adapter. The final configuration provides an integrated unit that is attached to the patient and in fluid communication with patient's vascular system.Type: ApplicationFiled: September 13, 2012Publication date: March 13, 2014Applicant: BECTON, DICKINSON AND COMPANYInventor: Stephen Bornhoft

Publication number: 20140039453Abstract: An infusion set preferably for use with an inserter is disclosed. The infusion set includes a septum cap that encapsulates an upper resilient septum and a lower resilient septum of a base, and includes at least one radial port to receive insertion of a blunt cannula when an extension set hub is engaged with the infusion set in a direction substantially parallel to the skin surface. The extension set hub is configured to provide a snap-fit engagement with the septum cap, wherein the blunt cannula of the extension set hub is guided through the radial port of the septum cap and penetrates the interface between the upper septum and the lower septum. The extension set hub and the septum cap can be rotated in a 360 degree manner about the base of the infusion set.Type: ApplicationFiled: July 16, 2013Publication date: February 6, 2014Applicant: Becton, Dickinson and CompanyInventor: Ralph L.

Patent number: 8641676Abstract: An exemplary infusion system for accessing an implanted device is disclosed comprising an insertion assembly, a hub comprising a sealable path configured to receive at least a portion of the insertion assembly, a flexible catheter attached to the hub and configured to receive at least a portion of the insertion assembly, and an extension tube attached to the hub. The hub may comprise a manifold element configured to provide fluid communication between the flexible catheter and the extension tube. The hub may also comprise a septum configured to seal the sealable path upon removal of the insertion assembly from the flexible catheter. The extension tube may also be configured to receive at least a portion of the insertion assembly. Exemplary methods of providing a fluid communication path to an implanted device are also disclosed.Type: GrantFiled: April 3, 2012Date of Patent: February 4, 2014Assignee: C. R. Bard, Inc.Inventors: David M. Butts, Jason R. Stats, Bret Hamatake, Sandra J. Rome, Walter H. Shang
