The invention provides mechanical devices to enhance the input process for touch screen devices. Fader tracks with or without fader caps, rotary and fixed knobs, and joysticks may be removably adhered to a touch screen and used to emulate their respective functions, using software interpretation of the touch detections provoked by the devices to carry out the emulations. The devices are inexpensive and simple, and the touch screen and associated software provide the function and feel of electromechanical controllers that are far more expensive and difficult to connect and maintain. The devices may be provided as components on a crack-and-peel sheet. For fixed knobs, the software application accepts initial inputs and determines the location on the touch screen, and also interprets the geometry of the input strokes as commands for selected controller emulations, such as joystick, fader, knob, or mouse. The invention also provides a touch sensor controller having a longitudinal web that incorporates touch sensor electrodes and conductors and emulates a fader controller. The invention further provides a flexible track controller mounted at the periphery of a touch screen and extendable thereover to emulate a fader controller. The flexible track may be motor driven.

Touch sensor control devices

Apparatus and methods for performing surgery within an organ or vessel are provided. A catheter is provided having a longitudinal axis and an end region carrying an end effector, the end region movable to a series of positions along the longitudinal axis and with an selectable orientation relative to the longitudinal axis. The catheter includes elements for stabilizing the end region of the apparatus within an organ or vessel, and for counteracting reaction forces developed during actuation of the end effector.

The system () includes a catheter drive unit () and a catheter () extending therefrom movably mounted to a catheter drive sled (). The catheter drive unit rotates and translates the catheter core () within the catheter sheath (). The sled has a serrated, conical drive unit interface (), with a bag-piercing tip () mateable with a translator drive output () so that a sterile drape () enclosing the catheter drive unit is automatically pierced when the catheter drive unit is mounted to the sled. A control unit () is spaced apart from the catheter drive unit and provides power and commands to the catheter drive unit and receives information and data from the catheter drive unit. The rotator and translator drive motors () are operated from both the control unit and the catheter drive unit. Both the control unit and catheter drive unit have translation displacement displays ().

Driveable catheter systems and methods

A method of performing a medical procedure on a living body is provided. The method comprises inserting a leading end portion of a guidewire into the living body and advancing a trailing end portion of the guidewire into a container, the container being arranged to coil the trailing end portion of the guidewire as the trailing end portion is advanced into the container. The invention extends to an advancing device operable to cause a trailing end portion of a guidewire to advance into a container. The advancing device comprises a body, an engaging mechanism on the body, the engaging mechanism being arranged releasably to engage the guidewire and to move relative to the body while engaging the guidewire thereby to cause the guidewire to advance through the body.

Apparatus and methods are provided for forming a channel in an organ or vessel to enhance perfusion therein. The apparatus may include a bioactive agent to stimulate tissue growth and vascularization in tissue adjacent to the channel. The apparatus includes a stent, suitable for percutaneous or intraoperative placement, that includes a tubular member having a plurality of tines, barbs, ribs or other structure to secure the stent at a desired position within tissue.

Methods and apparatus for perfusing tissue and/or stimulating revascularization and tissue growth

Apparatus and methods for stimulating revascularization and/or tissue

Apparatus having stabilization members for percutaneously performing

Apparatus and methods for intraoperatively performing surgery to create transmural channels in tissue, for example, as in transmyocardial revascularization, are provided using apparatus having an end region containing a mechanical cutting head and means for articulating the end-region to access hard-to-reach portions of the anatomy. The handpiece is coupled by a disposable cable to a controller that houses a vacuum pump and mechanisms for driving the cutting head. The cutting head is adapted to cooperate with the vacuum pump to evacuate tissue severed during the channel forming process.

Cutting apparatus having articulable tip

A system (2) includes broadly a catheter assembly (6) and a drive assembly (4). The catheter assembly includes a hollow sheath (20) housing a connecting element, typically a drive cable (22), with an operative element, such as a transducer (24), towards its distal end (26). The drive assembly is adapted to move the connecting element longitudinally within the hollow sheath. The drive assembly includes a main body (8) to which a proximal assembly, such as a rotary drive assembly (16), connected to the proximal end (28) of the connecting element, is mounted for longitudinal movement along the main body. The main body also has an anchor element (32) which is used to secure the sheath to the main body. A longitudinal drive motor (40) is carried by the main body and drives the proximal assembly along the main body.

Catheter system and drive assembly thereof

Apparatus and methods for intraoperatively performing surgery to create transmural channels in tissue, for example, as in transmyocardial revascularization, are provided using apparatus including a single-use handpiece having a mechanical cutting head and means for stabilizing the cutting head in contact with the tissue. The handpiece is coupled by a disposable cable to a controller that houses a vacuum pump and mechanisms for driving the cutting head. The cutting head is adapted to cooperate with the vacuum pump to evacuate tissue severed during the channel forming process.

Cutting apparatus having disposable handpiece

An operative element mover (22) is used as a part of an ultrasound imaging or other catheter system (2) including a hollow sheath (6) and a case (16) housing a rotary driver (10). A drive cable or other connecting member (8) is disposed within the sheath with a transducer (24) at its distal end (26) and its proximal end (12) coupled to the rotary driver. The rotary driver rotates the transducer about the longitudinal axis (14) of the sheath. A hemostasis valve (50) anchors the sheath to the patient where the sheath enters the patient. The transducer mover (22) is used to move the drive cable along the longitudinal axis and includes a body (38) fixedly mountable to and dismountable from the case and a movable anchor post (40). The anchor post is clipped to the sheath and is moved by a sheath anchor drive (46) to translate the sheath from or toward the case. This causes the transducer to move within the sheath in a proximal or distal longitudinal direction (52).
