Bladder cancer, a significant cause of morbidity and mortality worldwide, presents a unique opportunity for aggressive treatment due to the ease of transurethral accessibility. While the location affords advantages, transurethral resection of bladder tumors can pose a difficult challenge for surgeons encumbered by current instrumentation or difficult(More)
The rate and pattern of lever pressing were studied in nine rats during daily 6-hr sessions in which responding led to the i.v. injection of sodium methohexital. Level pressing was shown to be established and maintained by the response-drug contingency in the absence of physiological dependence or aversive stimulation. Effects of 1.0, 2.0, 3.0 and 4.0 (More)
Constrained motion control of robotic end-effectors is essential for safe operation in confined spaces such as the urinary bladder. This paper presents the clinical motivation for the development of new control algorithms for robotic-assisted transurethral bladder resection and surveillance using multisegment continuum robots. The anatomy, workspace, and(More)
BACKGROUND The magnetic surgical camera is an emerging technology having the potential to improve visualization without taking up port site space. However, tilting the point of view downward/upward can be done only by constantly applying a pressure on the abdomen. This study aims to test the hypothesis that the novel concept of local magnetic actuation(More)
OBJECTIVES To present the longitudinal outcomes in an observational cohort of patients who had undergone treatment of stress urinary incontinence with a single incision mid-urethral sling (MUS). METHODS A prospective, observational study of all female patients who had undergone surgical intervention with the MiniArc MUS was performed. The surgical(More)
A device for counting discrete puffs by cigarette smokers is inexpensive, easily constructed, and fully portable. The device consists of a plastic cigarette holder which is connected to a miniature pressure sensor via 18 gauge polyvinyl tubing. The pressure sensor has two electrical terminals which provide access to a normally open circuit which is closed(More)
