Patent number: 9687632Abstract: A catheter comprising an inner sleeve and an outer sleeve surrounding the inner sleeve, the inner and the outer sleeves being longitudinally displaceable relative to one another to enable the catheter to move from an open state to a closed state, each sleeve having a distal portion and a proximal portion, the catheter further comprising a retainer which is open in the open state, and closed in the closed state, the catheter further comprising a lock mechanism comprising lock formed in a lock portion of the catheter for locking the catheter in the open state, and a releaser for releasing the lock, the releaser being adapted to remove at least a part of the lock portion from the catheter.Type: GrantFiled: June 23, 2010Date of Patent: June 27, 2017Assignee: Mediplus LimitedInventor: Robert Graham Urie

Patent number: 9352132Abstract: A catheter guidewire for facilitating introduction of a flexible catheter into the human body (e.g., into the bladder) has a proximal end having a first stiffness which is sufficient to facilitate guidance of a stiff plastic expansion sheath through the tissue. A distal end of the guide wire has a second stiffness, substantially less than the first stiffness, to avoid damage to internal walls of the bladder. Preferably, the guide wire incorporates an intermediate portion having a stiffness between the first stiffness value and the second stiffness value.Type: GrantFiled: May 27, 2014Date of Patent: May 31, 2016Assignee: Mediplus LimitedInventor: Robert Graham Urie

Patent number: 6506169Abstract: A method and apparatus for carrying out non-invasive urodynamics investigations on male patients, by controlling urethral pressure, which facilitates diagnosis of, and distinction between, obstructive and non-obstructive voiding dysfunction. A pneumatic cuff (2) is placed around the penis (3) and after commencement of urine flow through the penis, the cuff is automatically inflated over a period of time in order to gradually occlude the urethra before voiding of the bladder is complete. A relationship between the urine flow and the cuff pressure applied is established and this is used to determine a pressure measurement related to the bladder pressure under isovolumetric conditions.Type: GrantFiled: May 4, 2001Date of Patent: January 14, 2003Assignee: Mediplus LimitedInventor: Clive Javan Griffiths
