  • Patent number: 11980745
    Abstract: A low-waste needle and syringe assembly for injecting a fluid into a patient is provided. The syringe has hatch marks printed on the outer wall of the body to indicate the amount of fluid and/or the concentration of the fluid contained in a fluid chamber of the syringe. A syringe tip defining a substantially frusto-conical interior void extends from an end wall of the syringe. A needle hub holds a needle and is configured so that the hub can be selectively and securedly attached to the syringe. A frusto-conical member of the needle hub matingly engages the frusto-conical void of the syringe tip when the hub is secured to the syringe, forming a fluid-tight seal. A plunger positioned in the fluid chamber can be depressed by a user, and a piston cap attached to the plunger urges fluid in the chamber out of the chamber through the syringe tip and into the needle. The piston cap matingly engages the end wall of the syringe so that substantially all fluid is urged from the chamber to the needle.

  • Patent number: 6953380
    Abstract: A postoperative bilateral augmentation mammaplasty brassiere for use by women with augmented breasts is disclosed. The brassiere provides a support cup shaped to mimic a spherically shaped breast implant. The brassiere further provides an underwire within the construction of the brassiere, the underwire having an arcuate portion to mimic the round base of an augmented breast. A connector is provided between two support cups, each with an associated underwire, such that the distance between proximal ends of the underwires is established for the comfort of the wearer and the attractive appearance of the brassiere.
