  • Patent number: 5597378
    Abstract: Medical devices which are currently proposed to use elements made form shape memory alloys may be improved by the use of stress-induced martensite alloy elements instead. The use of stress-induced martensite decreases the temperature sensitivity of the devices, thereby making them easier to install and/or remove.

  • Patent number: 5588954
    Abstract: A fluid connector for a compression system for improving venous blood flow in a patient provides a continuous fluid passageway between a source of pressurized fluid and a plurality of inflatable chambers in an elongated pressure sleeve. The connector includes a flexible conduit comprising a plurality of elongate hollow tubes having a corresponding plurality of fittings attached at one end of the conduit. The fittings form a fluid-tight seal between the conduit and a corresponding plurality of outlet ports communicating with the source of pressurized fluid. A grip portion is provided adjacent the end of the conduit. The grip portion is releasably attached to the source of pressurized fluid and grips the conduit securely between adjacent tubes such that the fittings move freely and independently relative to the grip portion. In this manner, leakage of the pressurized fluid and contamination of the fluid stream is minimized, while stresses induced in the conduit are not transferred to the fittings.

  • Patent number: 5582580
    Abstract: A heart massager for substernal heart massage is disclosed. The heart massager has a heart-contacting member having a surface which is at least partially concave for contacting the heart, cushioning on the surface of the contact member, and a handle attached to the heart-contacting member for manually manipulating the massager. The partially concave surface allows the heart-contacting member to conform to the shape of the heart. The handle is substantially upright with respect to the surface of the heart-contacting member. The handle is significantly offset from a central portion of the heart-contacting member in the region where it attaches to the member. The cushioning covers substantially the entire surface of the heart-contacting member so as to form a solid surface.

  • Patent number: 5577994
    Abstract: A massage appliance has a container which is moved in contact with the body of the massaged person and a handle connected with the container by a fork and pivot bearing arrangement such that the container can pivot about one axis with a swinging movement and rotate about another axis. A torsion spring restores the position of the container relative to the handle and a suction pipe is connected to the container so that suction can be applied concurrently with massage.

  • Patent number: 5571074
    Abstract: A heart massager for substernal heart massage is disclosed. The heart massager utilizes a heart-contacting member adapted for insertion into a thoracic cavity for directly contacting the heart and a handle attached thereto for manually manipulating the apparatus. The heart-contacting member includes a cup having one end which is open and which receives the handle, and another end which is closed by an at least partially concave-shaped diaphragm which forms a heart contacting surface and allows the member to conform to the shape of the heart's surface. The ends of the cup are joined by a flexible sidewall which flares outward from the handle in its operative state. The cup's flexible sidewall allows the heart-contacting member to collapse so that it can be inserted into a relatively small incision in the chest cavity. After the heart-contacting member is inserted, fluid pressure is applied to the inside of the cup, thereby causing it to expand into its operative state.

  • Patent number: 5569168
    Abstract: A kneader massager includes a housing having an upper portion and a lower portion, each upper and lower portion partially defining a power transmission chamber having at least one opening. Also included is least one pair of massaging members for massaging the skin of a user, with each such pair of massaging members being mounted in the chamber for reciprocating movement relative to each other, and extending through the at least one opening in the housing. A motor is provided for powering the massaging members and is disposed in the power transmission chamber, and a drive assembly is also disposed in the power transmission chamber for transmitting power from the motor to the massaging members to move each pair of the massaging members between a relaxed position and a pressing position relative to each other. A principal feature of the present invention is the provision of a dwell feature in the drive assembly for periodically prolonging the massaging members in said pressing position.

  • Patent number: 5562604
    Abstract: Portable therapeutic devices and methods for employing them are provided by this invention. The devices include a flexible containment bag including a fluid chamber containing a fluid medium and a self-contained pumping means disposed within the device for causing the fluid medium to circulate within the fluid chamber to provide a therapeutic effect upon contacting the device with a patient. In preferred embodiments of this invention, integral electromagnetic transducer assemblies are employed to create a pumping action within serpentine fluid channels, and solid state heat pumps are employed to control the temperature of the fluid during therapy. The devices of this invention are ideal for treating lower back pain and post-operative conditions associated with spinal surgery, as well as veterinarian treatments.
