Abstract: A patient interface for coupling an ophthalmological application head to an eye of a patient includes a patient-sided interface structure to be coupled to the eye of a patient, and a source-sided interface structure for rigidly coupling the patient interface to the application head or an intermediate element. The source-sided interface structure comprises a first source-sided patient interface coupler and a second source-sided patient interface coupler. The first source-sided patient interface coupler is designed to restrict the mobility of the patient interface relative to the application head or the intermediate element by providing a coupling with a first patient interface coupler counterpiece of the application head or the intermediate element.

Abstract: An MR compatible steerable sheath with elastomeric member is provided. The elastomeric member is configured to serve as a reservoir and receive contrast media therewithin. The elastomeric member is positioned on the distal end of the steerable sheath and may circumferentially surround the sheath shaft or be offset from a longitudinal axis thereof. In operation, the contrast media allows a user to view the distal tip of the steerable sheath by virtue of the contrast media contained within the elastomeric member.

Abstract: Provided is a medical treatment tool, the distance between a first advance and retraction axis, and a tip end is shorter than the length of the first link member, and the length when a line segment connecting the base end and the center of a forceps rotation shaft is projected on the first advance and retraction axis is shorter than the length is projected on the first advance and retraction axis. The distance between a second advance and retraction axis, and a tip end is shorter than the length of the second link member, and the length when a line segment connecting the base end and the center of a forceps rotation shaft is projected on the second advance and retraction axis is shorter than the length projected on the second advance and retraction axis.

Abstract: A combination therapy pad that includes a first layer and a second layer operatively coupled to the first layer. A fiber-optic array is disposed between the first layer and the second layer. A third layer is operatively coupled to the first layer. The third layer includes a vacuum tube in fluid communication with a vacuum source and a therapeutic fluid tube in fluid communication with a therapeutic fluid source. The third layer provides at least one of vacuum therapy and therapeutic fluid treatment to a wound area.
