Patents by Inventor Girum Yemane Tekeste

Girum Yemane Tekeste has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20130281941
    Abstract: Flush syringe assemblies capable of creating pulsatile movement of the plunger rod as it moves in the distal direction within a syringe barrel, while preventing overpressurization of the cathether are provided. An exemplary flush syringe assembly includes a syringe barrel with a first pulsing element and a chamber with flush solution, a plunger rod with a stopper and a second pulsing element that interacts with the first pulsing element to provide an engagement force that causes pulsatile movement of the plunger rod and a thumb press slidably attached to the plunger rod with a pulse control element. The pulse control element is compressible to create a compression force that is greater than the engagement force of the first pulsing element and the second pulsing element.

  • Patent number: 8394068
    Abstract: Syringe assemblies for use in flush applications are provided. Syringe assemblies according to one aspect of the present invention include a plunger rod and a syringe barrel that incorporate one or more pulsing elements on the plunger rod or barrel that are rotatable to create pulsatile movement or continuous and unimpeded movement a plunger rod within a syringe barrel. One or more embodiments pertain to syringe assemblies permit both pulsatile movement of the plunger rod within the barrel and continuous and unimpeded movement of the plunger rod in the distal direction along substantially the entire length of the syringe barrel upon application of force to the plunger rod in only the distal direction. Methods of flushing a catheter are also provided.

  • Publication number: 20120253291
    Abstract: A stopper adapted for attachment with a plunger rod for use within a syringe barrel includes a main body portion defining an open rearward end configured to receive the plunger rod. The main body portion is manufactured from a rigid or semi-rigid polymeric material having an elastic modulus in the range of about 0.01 GPa to about 5 GPa. When fluid pressure is increased inside the syringe barrel during an injection, at least one of the following actions occurs: a) a flexible roof of the main body portion expands in a radial direction toward an inner wall of the syringe barrel; b) a first perimetrical skirt extending around an outer circumference of the main body portion is forced against an inner wall of the syringe barrel; and c) an engagement between the plunger rod and an engagement portion provided along an inner circumference of the main body portion.

  • Publication number: 20120253292
    Abstract: A stopper includes a main body portion defining an open rearward end configured to receive the plunger rod, an engagement portion provided along an inner circumference of the main body portion configured to engage at least a top portion of the plunger rod, a closed front end forming a flexible roof, and a first perimetrical skirt extending around an outer circumference of the main body portion toward the closed front end of the main body portion. When fluid pressure is increased inside the syringe barrel during an injection, the flexible roof expands in a radial direction toward an inner wall of the syringe barrel, the first perimetrical skirt is forced against the inner wall of the syringe barrel, and an engagement between the plunger rod and the engagement portion forces the main body portion to expand in the radial direction toward the inner wall of the syringe barrel.

  • Publication number: 20120245564
    Abstract: Devices having male connectors for preventing connection to non-compatible female connectors are described. An exemplary male connector includes an elongate tip and a collar disposed coaxially around the elongate tip including a plurality of ribs disposed on either an inside surface or an outside surface of the collar for preventing entry of a non-compatible female connector into a channel formed between the elongate tip and the collar. One or more embodiments pertain to a device with a male connector and a compatible female connector including a threaded portion for engaging a corresponding threaded portion of the male connector.
