ABSTRACT:
An infusion apparatus including a support member and an elastic sleeve surrounding the support member to define a fluid reservoir therebetween. The sleeve is expandable in a radial direction when the infusion apparatus is loaded with a fluid, such as a pain medication, and exerts a pressure on the fluid so that it may be delivered to a desired site, such as a surgical region of a patient. The elastic sleeve is sealed to the support member at spaced-apart locations by first and second sealing arrangements. Each sealing arrangement preferably includes a sealing member having a first end, a second end, and a body portion extending between the first and second ends. Desirably, the body portion is substantially annular in shape and is deflectable between a first inner diameter and a second inner diameter. The first inner diameter permits the sealing member to be passed over an end of the support and elastic sleeve, while the second inner diameter is configured to produce a force tending to create a fluid tight seal between the elastic sleeve and the support.
