The present invention provides a device and method for delivering thermal therapy about a percutaneous access site while also permitting visual and physical examination of the access site. The device comprises a semi-circumferential shaped housing having a top wall, a bottom wall, and a side wall. The top wall, the bottom wall, and the side wall define a cavity with a fluid tight bladder disposed within the cavity. The semi-circumferential shaped housing has an aperture formed in the housing and a straight edge portion along the circumference of the housing. The device delivers thermal therapy to percutaneous arterial, venous, laparoscopic, and other access procedures sites by allowing visual and physical examination of the access site through the aperture and comfortable placement of the device's straight edge portion against a bend or joint of the patient's body.
