  • Patent number: 10821224
    Abstract: The present invention is directed to a portable apparatus for dispensing a liquid under pressure at a substantially constant flow rate over a period of time. The apparatus includes an inflatable, internal bladder constructed of a compliant, elastomeric material and an external housing surrounding the internal bladder. Further, the external housing is constructed of a non-compliant, elastomeric material. Thus, during operation, the external housing shapes the internal bladder as the internal bladder is being filled with a treatment fluid and collapses as the treatment fluid is emptied from the internal bladder.

  • Patent number: 10773055
    Abstract: The present invention is directed to an echogenic member assembly for use with a catheter assembly. The echogenic member assembly includes at least one echogenic member having a cylindrical body extending between a first end and a second end. Thus, the body defines a longitudinal length between the first and second ends. Further, the cylindrical body has an exterior surface extending from the first end to the second end. The exterior surface includes a plurality of discontinuities arranged in a predetermined pattern so as to enhance ultrasonic imaging. In addition, the longitudinal length of the echogenic member is less than a total length of a catheter of the catheter assembly. As such, the echogenic member provides enhanced ultrasonic imaging to the catheter assembly without compromising the inherent flexibility of the catheter.

  • Patent number: 10675441
    Abstract: The present invention is directed to an echogenic coil member for a catheter assembly and methods of manufacturing same. The catheter assembly includes a catheter having a proximal end and a distal end that defines a lumen extending from the proximal end to the distal end. Thus, the echogenic coil member is configured within the lumen of the catheter. Further, the coil member includes a plurality of outwardly extending projections that contain a plurality of discontinuities. As such, the discontinuities are configured to enhance ultrasonic imaging of the catheter assembly.

  • Patent number: 9968350
    Abstract: A blunted safety needle is provided, which includes a hollow needle having a sharp distal tip and a stylus having a blunted end. The stylus is positioned within at least a portion of the needle. After the needle is used to deliver or deploy a substance and/or a device, the blunted end of the stylus is positioned to extend through the sharp distal tip of the needle and un-releaseably lock into position, thereby providing a blunted safety needle assembly.

  • Patent number: 8382772
    Abstract: A gastropexy kit includes a plurality of safety needle assemblies. Each safety needle assembly includes a needle and a stylus. A fastener is positioned in a distal end of the needle. The fastener is coupled to one end of the suture and a suture retention hub is coupled to an opposite end of the suture. The fastener is deployed in a patient's stomach via the needle and stylus which has a blunt distal end which extends through the needle to push the fastener out of the needle and to blunt the needle. The suture retention hub is positioned on a patient's skin and adjustably tensions the suture, which, desirably, is a resorbable suture.

  • Patent number: 7867253
    Abstract: A suture retention hub is provided. It includes a base configured to moveably hold a handle within at least a portion of the base. The base has an aperture which extends through the base. The hub also includes a handle configured to moveably fit into the portion of the base. The handle has an aperture formed therethough as well. When a suture is positioned in the apertures and the base and handle are positioned such that the apertures are substantially in an axial alignment, the suture moves readily through the apertures in the hub. Then the base and handle are positioned such that the apertures are not in a substantial axial alignment, the suture is frictionally crimped and it is prevented from moving through the hub.

  • Publication number: 20080120758
    Abstract: Thermal impulse heat welding, or “bar sealing”, is used to bond thermally sensitive laminate barrier materials such that they will pass AAMI level 4 testing (ASTM 1670 and 1671-b). In bar sealing, overlapping layers of thermally sensitive laminate barrier materials are melted and fused together to create a substantially solid bond at and/or adjacent the surface. No substantially un-melted areas remain within the fused bond area on the surface.
