  • Patent number: 5002564
    Abstract: A spatulated needle is provided wherein a six-sided cross-sectional portion results from a parallel or tapered pair of upper and lower surfaces connected by needle walls and a pair of fluted edges. At the tapered end of the needle, the upper surface alternates resulting in a five-sided cross-section. This improved configuration results in ease of tissue penetration, minimized tissue distortion, and minimized wound trauma. The resultant needle therefore is desirable for usage with refined surgery such as ophthalmology, microsurgery and plastic surgery.

  • Patent number: 4994056
    Abstract: A unit dose medicament storing and mixing system is described having a dual compartmented and collapsible container for use in an intravenous administration system. One of the compartments contains unit dose measurements of sterile medicament (in powder or liquid form), the second compartment to contain sterile intravenous fluid to be used as a diluent. The two compartments are separated by a closure which is separable and resealable. An external clamping device is used to lock the resealable closure and keep the compartments separate. Prior to the infusion of the activated medicament to the patient, the drug is prepared by removing the external clamp and separating the resealable membrane device, thereby providing fluid communication between chambers and effecting intermixing of the contents thereof. The membrane can then optionally be resealed in order to separate the medicament to be delivered from any residual air left in the container.

  • Patent number: 4990154
    Abstract: A lancet assembly includes a reusable base unit that defines a handle for a lancet assembly and houses a biasing mechanism for driving a lancet into the finger of a user. The base unit includes a spring biased hammer that once cocked, can be released to drive a lancet. A lancet is included in a disposable end cap that may be releasible attached to one end of the base unit. The end cap includes integral resilience spring fingers that maintain the lancet completely within the end cap before and after use, and functions to return the lancet after engagement of the lancet and hammer. The end cap can be rotated to orient the end cap relative to a user's finger to control the depth of penetration of the lancet into the user's finger.

  • Patent number: 4990148
    Abstract: A rongeur with special features applied to the footplate area to prevent the intersection of stress fields to allow the rongeur to be reduced in size and mass without materially reducing the strength of the rongeur. A transverse groove is used at the intersection of the anvil surface of the base plate and the shank base plane. Also the base of the footplate recess is offset from the shank base plane and the inside wall of the recess meets the recess base in a gentle curve. These features can be used individually or together to prevent the intersection of stress fields in the footplate area and thus allow the size of the footplate to be reduced without materially reducing the strength of the rongeur.

  • Patent number: 4986807
    Abstract: An atherectomy device for cutting obstructive tissue from the lumen of a body vessel comprises a rotatable cutter having a blade. A hollow, generally cylindrical housing defines a central longitudinal axis and has a side opening. The cutter is mounted in the housing for rotation about an axis that is substantially parallel to the longitudinal axis of the housing. During rotation of the cutter, the blade cyclically projects from the side opening to cut obstructive tissue from the lumen.

  • Patent number: 4981148
    Abstract: A back traction device is disclosed that allows a person to be seated in any type of seat and will relieve the pressure, weight and tension on the disc of the lower back of the patient as much as possible. The back traction device consists of a halter that serves to transfer some of the pressure that is associated with sitting in a seat or chair off of the patient's lower back. The back traction device further includes a two-part traction member having a clip-like portion to be received over the back of the seat and a downwardly extending strap portion to be connected to the clip portion. The clip portion is first affixed to the seat back and the strap portion connected thereto. The strap portion has a securing surface that will attach to a corresponding securing surface on the halter member. An inflated air cushion is disposed between the seat occupant and the seat prior to connection of the halter to the strap portion.

  • Patent number: 4979949
    Abstract: A system and method for positioning a tool relative to a patient's bone to facilitate the performance of a surgical bone alteration task. The system comprises a bone immobilization device for supporting the bone in a fixed position with respect to a reference structure, and a robot that includes a base fixed in position with respect to the reference structure. The robot also includes a mounting member, and a manipulator connected between the base and the mounting member and permitting relative movement therebetween. The tool to be positioned by the system is mounted to the mounting member. The mounting member is caused to move relative to the reference structure in response to movement commands, so that the tool can be moved to a desired task position to facilitate performance of the task. The system preferably also includes a template attachable to the mounting member, a feature of the template representing a portion of a task.
