Abstract: A surgical tool with a stiffening sleeve that is dynamically retractable during surgery. The tool includes a needle or implement for performing minimally invasive surgery through a pre-placed cannula at a surgical site. A stiffening sleeve of the tool about the implement may provide an added degree of stiffness such as where the implement is particularly thin. However, an end of the sleeve is held in position at the cannula as the implement advances therebeyond for the surgery. Nevertheless, as determined by the surgeon, the implement may be further advanced with a corresponding and deliberate retraction of the sleeve into the tool body as desired.

Abstract: A surgical tool with an elongated implement of enhanced stiffening character due to the use of a stiffening coating and/or a lumen of inconsistent diameter. The stiffening coating may be supplied by a deposition technique utilizing materials tailored to biocompatibility, stiffening and even to reducing glare. The lumen of inconsistent diameter may include a distal end taking up a minority of the lumen that is of a larger diameter than a proximal portion of substantially smaller diameter for increasing wall thickness and stiffening of the majority of the implement.

Abstract: A surgical tool for eye surgery that utilizes a stiffening sleeve and employs a needle of extendible reach. The reach off the needle into the eye is dynamically adjustable by forcible interaction between the stiffening sleeve and a cannula at an outer location of a patient's eye. An end of the tool may retract to facilitate extension of the needle for added reach. Additionally, the sleeve may be further independently retracted for even greater reach of the needle implement toward a surgical site within the eye of the patient.
