Claim 12

An orthopedic cushion fitted to an orthopedic patients body comprising: a unitary structure including: a flexible envelope, the envelope defining an interior volume; an elongated member outwardly protruding from the envelope, the elongated member including a narrow passageway in communication with the first envelope volume at a passageway one end and being spaced outward of the flexible envelope and away from that portion of the envelope against which the patient's body will bear; and sealing means for sealing the elongated member at a point spaced from the passageway one end, the sealing means fixidly interrupting the envelope volume communication with the passageway and closing the passageway; and a non-set and flowable, highly viscous material contained within the envelope volume, the viscous material having been vacuum packed therein, the contained viscous material in an amount less than the vacuum packed amount.

Claim 13

The orthopedic cushion as in claim 9, wherein the sealing means comprises: a radio frequency seal.

Claim 14

An orthopedic cushion fitted to an orthopedic patient's body comprising: a unitary structure including: a flexible double envelope with a first envelope and a second envelope, the first envelope defining a first interior volume, the first envelope enclosed by the second envelope; an elongated member outwardly protruding from the double envelope, the elongaged member including a narrow passageway in communication with the first envelope volume at a passageway one end and being spaced outward of the double envelope and away from that portion of the envelope against which the patients body will bear; and sealing means for sealing the elongated member at a point spaced from the passageway one end, the sealing means fixedly interrupting the envelope volume communication with the passageway and closing the passageway; and a non-set and flowable, highly viscous material contained within the envelope volume, the viscous material having been vacuum packed therein, the contained viscous material in an amount less than the vacuum packed amount.

Claim 15

An orthopedic cushion fitted to an orthopedic patient's body comprising: a unitary structure including: a flexible double envelope with a first envelope and a second envelope, the first envelope defining a first interior volume, the first envelope enclosed by the second envelope; an elongated member outwardly protruding from the double envelope, the elongaged member including a narrow passageway in communication with the first envelope volume at a passageway one end and being spaced outward of the double envelope and away from that portion of the envelope against which the patients body will bear; and sealing means for sealing the elongated member at a point spaced from the passageway one end, the sealing means fixedly interrupting the envelope volume communication with the passageway and closing the passageway; and a non-set and flowable, highly viscous material contained within the envelope volume, the viscous material having been vacuum packed therein, the contained viscous material in an amount less than the vacuum packed amount.
