Abstract
Abstract Apparatus for positioning the body of a patient during open heart surgery and the like includes a pair of spaced leg supports each having a leg support surface which includes resilient thigh and calf support surfaces having a sloping contour for positioning the leg in a rotated position affording access thereto for vein removal and a foot support for supporting the foot and ankle portion at a desired elevation and pressure. In one embodiment, the leg support surface is made as a disposable outer layer wherein the individual leg supports are reusable.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
198 words
An apparatus for positioning the body of a patient during heart surgery and the like comprising: a pair of spaced leg supports each of which includes: a thigh support having a sloping contour for properly positioning the thigh portion of said leg; a calf support having a sloping contour for properly positioning the calf portion of said leg; said sloping contour of said thigh and calf supports positioning said leg in an externally rotated position affording access to an inside portion thereof; a resilient deformable outer layer overlying said thigh and calf supports providing a resilient leg support surface which includes a resilient thigh support surface conforming generally with said thigh support and a resilient calf support surface conforming generally with said calf support, respectively, when carried thereon; said leg support surface including a knee support position having pressure relief means for relieving pressure on said leg in the peroneal nerve area damage avoiding damage thereto; and means for removably fastening each said resilient leg support surface and leg support in an integral manner; whereby a patient's leg supported on one of said resilient leg support surfaces is properly positioned by the contour of said leg support therebeneath.
Claim 2
Independent Claim
198 words
An apparatus for positioning the body of a patient during heart surgery and the like comprising: a pair of spaced leg supports each of which includes: a thigh support having a sloping contour for properly positioning the thigh portion of said leg; a calf support having a sloping contour for properly positioning the calf portion of said leg; said sloping contour of said thigh and calf supports positioning said leg in an externally rotated position affording access to an inside portion thereof; a resilient deformable outer layer overlying said thigh and calf supports providing a resilient leg support surface which includes a resilient thigh support surface conforming generally with said thigh support and a resilient calf support surface conforming generally with said calf support, respectively, when carried thereon; said leg support surface including a knee support position having pressure relief means for relieving pressure on said leg in the peroneal nerve area damage avoiding damage thereto; and means for removably fastening each said resilient leg support surface and leg support in an integral manner; whereby a patient's leg supported on one of said resilient leg support surfaces is properly positioned by the contour of said leg support therebeneath.
Claim 3
Dependent Claim
34 words
The apparatus of claim 1 wherein each said resilient leg support surfaces includes a depression intermediate the thigh and calf support surfaces affording relief of pressure on the peroneal nerve area of the leg.
Claim 4
Dependent Claim
28 words
The apparatus of claim 2 wherein said depression is defined by a hollow cut-out portion formed in said leg support surface intermediate said thigh and calf supporting surfaces.
Claim 5
Dependent Claim
44 words
The apparatus of claim 1 including pressure distribution means formed in each said resilient leg support surface serving to break the integrity of said thigh and calf support surfaces accommodating differences in thigh and calf shapes and weights and evenly distributing the pressure thereon.
Claim 6
Dependent Claim
20 words
The apparatus of claim 1 wherein said leg supports are integrally joined by a web limiting the lateral separation therebetween.
Claim 7
Dependent Claim
18 words
The apparatus of claim 1 wherein said thigh and calf supports have a longitudinal and lateral sloping contour.
Claim 8
Dependent Claim
40 words
The apparatus of claim 1 including Velcro hook and pile fastening tape carried on respective mating faces of each said leg support and leg support surface providing said means for removably fastening said leg support and resilient leg support surface.
Claim 9
Dependent Claim
175 words
For use with apparatus for positioning the body of a patient during heart surgery and the like of the type having a pair of spaced leg supports each of which includes a base support block having a thigh support for supporting the thigh portion of said leg, and a calf support for supporting the calf portion of said leg, a disposable topper cushion overlying said thigh and calf supports comprising: a resilient deformable outer layer providing a cushioned thigh support surface and calf support surface for said leg supported and positioned thereon; means for removably fastening said resilient outer layer in said overlying position; said thigh and calf support surfaces providing a sloping contour for properly positioning said leg in an externally rotated position affording access to an inside portion thereof; and said thigh support surface sloping downwardly and laterally from a high inside edge to a lower outside edge facilitating access to said inside portion of said thigh when said disposable topper cushion is fastened in overlying position on said thigh and calf supports.
Claim 10
Dependent Claim
175 words
For use with apparatus for positioning the body of a patient during heart surgery and the like of the type having a pair of spaced leg supports each of which includes a base support block having a thigh support for supporting the thigh portion of said leg, and a calf support for supporting the calf portion of said leg, a disposable topper cushion overlying said thigh and calf supports comprising: a resilient deformable outer layer providing a cushioned thigh support surface and calf support surface for said leg supported and positioned thereon; means for removably fastening said resilient outer layer in said overlying position; said thigh and calf support surfaces providing a sloping contour for properly positioning said leg in an externally rotated position affording access to an inside portion thereof; and said thigh support surface sloping downwardly and laterally from a high inside edge to a lower outside edge facilitating access to said inside portion of said thigh when said disposable topper cushion is fastened in overlying position on said thigh and calf supports.
Claim 11
Dependent Claim
