Specific Structure Of Body Entering Or Piercing Conduit Patents (Class 604/239)
  • Patent number: 11051939
    Abstract: The active introducer sheath systems disclosed herein are expanded by activating a translation mechanism at the handle. The sheath has an inner cylindrical structure of comingled fixed and mobile elongate rods bound together by an attachment line. Activating the translation mechanism causes the mobile rods to move axially with respect to the fixed rods, changing the internal tension in the attachment line. Increased tension draws the fixed and mobile rods closer together, decreasing the diameter of the cylindrical structure. Decreased tension in the attachment line enables the fixed and mobile rods to move apart, increasing the diameter of the cylindrical structure. A prosthetic device, such as a prosthetic heart valve, can be routed through the expanded sheath and to the implantation site. During implantation, the sheath can be contracted back to its original outer diameter, and expanded again for retrieval of the delivery apparatus.

The ocular devices may maintain the patency of Schlemm's canal without substantially interfering with transmural fluid flow across the canal. The fluid composition may be a viscoelastic fluid that is delivered into the canal to facilitate drainage of aqueous humor by disrupting the canal and surrounding trabeculocanalicular tissues. Tools for disrupting these tissues and minimally invasive methods for treating medical conditions associated with elevated intraocular pressure, including glaucoma, are also described.

  • Patent number: 8540684
    Abstract: The intervertebral disc is avascular. With aging, endplates become occluded by calcified layers, and diffusion of nutrients and oxygen into the disc diminishes. The disc degenerates, and pain ensues. Conduits are delivered and deployed into the intervertebral disc to re-establish the exchange of nutrients and waste between the disc and bodily circulation to stop or reverse disc degeneration and relieve pain. The intervertebral disc installed with semi-permeable conduits may be used as an immuno-isolated capsule to encapsulate donor cells capable of biosynthesizing therapeutic molecules. The semi-permeable conduits establish the exchange of nutrients and therapeutic molecules between disc and bodily circulation to treat a disease without using immuno-suppressive drugs.

  • Patent number: 8518017
    Abstract: A self-cleaning suction device has a user's suction end that self-sanitizes externally and internally before and after use, as well as self-sanitizes internally during use. A cover opens to reveal the user's suction end within a containment unit. As the cover opens, the suction end travels from a lower chamber, proceeds through a middle chamber of a sanitizing agent, and is presented for use. After suction is complete, the suction end retracts through an upper chamber with, a scraping feature that removes debris from the outer surface of the mouthpiece, and proceeds down through the middle chamber of a sanitizing agent and a scraping feature that removes debris and the sanitizing agent from the outer surface of the user's suction end. Upon the sealing closure of the cover, the upper and middle chambers are flushed with a sanitizing agent, which is suctioned away along with any collected debris.

  • Patent number: 8491521
    Abstract: An applicator for use with an ultrasound transducer assembly is disclosed. In an embodiment, an applicator includes a nozzle body having an interior and an exterior surface; a nozzle liner having an interior and an exterior surface and being engageable with the nozzle body such that a plurality of channels are defined at least in part by the exterior surface of the nozzle liner and the interior surface of the nozzle body, each of the plurality of channels having an inlet and an outlet; a passageway defined by a space between the nozzle body and the nozzle liner, in fluid communication with the inlets of each of the plurality of channels; and an opening sized and shaped for introducing fluid to the passageway to provide fluid flow from the outlet of each of the plurality of channels essentially simultaneously. Kits and methods are also disclosed.

  • Publication number: 20130184654
    Abstract: A catheter proximal section is preferably formed from a relatively soft part and a relatively rigid part, and includes a proximal terminal end that defines a perimeter of an opening into a lumen of the catheter. The proximal section may further include a feature for interlocking engagement with an accessory tool. An inner surface of each of the relatively soft and rigid parts may be located opposite one another, on either side of the catheter lumen. The relatively soft and rigid parts may be included in a sealing assembly that further includes an attachment feature for removable connection of the assembly to the proximal section catheter.

  • Patent number: 8460272
    Abstract: The extensible intravenous (“i.v.”) drip line tubing uses a helical accordion support structure on which the i.v. tubing is attached. The helical accordion backbone has some tendency to spring back, but this is not relied upon to extend and return the i.v. tubing it carries. The carrier structure keeps the i.v. tubing from getting tangle or kinked. A centrally located retractable line, which is located within the center of the helical accordion structure, acts as the retracting mechanism, as it tends to allow the accordion structure to be pulled into an extended position, while upon rewinding the central cord, the helical accordion support structure can be pushed toward a collapsed position without the i.v. drip line tubing becoming tanked, kinked, and thereby blocked. As a safety feature, so the i.v. line does not encounter and strain between it and the point of entry of the i.v. line into the patient, is one or more wrist and or armbands to which the i.v. carrier is attached by a short, strong line.

  • Publication number: 20130110049
    Abstract: The subject invention provides a drug delivery device for injecting medicament which includes: a tubular reservoir; a stopper slidably disposed in the reservoir; a spring for moving the stopper in the reservoir; at least one needle, the needle having a distal end for insertion into a patient, and a lumen extending proximally from the distal end, the lumen being in direct or indirect communication with the reservoir; a needle driver for displacing the needle; and, an actuator. Activation of the actuator causes the spring to move the stopper and the needle driver to displace the needle. The needle moves relative to, and separately from, the reservoir with the needle being displaced. Advantageously, with the subject invention, a drug delivery device is provided wherein a needle is moved, relative to the reservoir, in being displaced for injection. This permits control of the needle displacement separate from the reservoir.
