A system for measuring cardiovascular data includes an elongate member having a channel, a first expandable member carried by the elongate member and movable between a collapsed state and an expanded state by adjustment initiated externally of a subject, a first sensor disposed on a surface of the elongate member, second and third sensors disposed on a surface of the first expandable, a first optical sensor located at a first location in relation to the distal end of the elongate member and configured for obtaining photoplethysmographic data, and wherein the first expandable member in its expanded state is configured to interface with the subject's larynx for delivery of at least oxygen gas into the respiratory system of the subject, and the second and third sensors are configured to contact tissue in proximity to the larynx when the first expandable member is in its expanded state.

A method for applying a predetermined pattern of material onto an elongate tubular substrate includes securing a first portion of an elongate tube having a non-circular outer perimeter to an engagement member configured to be rotated by a first motor, such that the elongate tube can be rotated in unison with the engagement member, operating the first motor to rotate the elongate tube, operating a second motor of to change the relative displacement between the elongate tube and a dispensing conduit along a longitudinal axis of the elongate tube, and expelling a conductive adhesive from a fluid dispenser through the dispensing conduit to form a predetermined pattern of the conductive adhesive on a surface of the elongate tube, the predetermined pattern of the conductive adhesive covering at least 180 degrees of the surface along the non-circular outer perimeter over a width of at least two millimeters along the longitudinal axis.

Systems and methods for applying materials to medical devices

A mechanism for applying a predetermined pattern of material onto an elongate tubular substrate includes a first motor, an engagement member rotatable by the first motor and configured to reversibly grasp an elongate member, such that rotation of the first motor rotates the elongate member around its longitudinal axis, a fluid dispenser configured to dispense a fluid having a first, flowable state, the fluid dispenser including an elongate dispensing conduit having a distal end having an orifice, the orifice configured to be placed adjacent a surface of the elongate member, a second motor configured to move at least one of the elongate member or the elongate dispensing conduit such that the orifice changes its relative orientation along the longitudinal axis of the elongate member, and wherein the distal end of the elongate dispensing conduit is configured to apply a bias on the surface of the elongate member.

A system for performing a diagnostic or therapeutic procedure within a subject includes a device having a distal portion configured for insertion within a lumen or duct of the subject, the device including an elongate body having a longitudinal axis, the elongate body comprising a polymeric material and having a proximal end and a distal end, one or more electrically-conductive tracings carried on a first surface of the elongate body and configured to carry a signal, and one or more conductors embedded within the polymeric material and configured to carry a signal.

A system for obtaining signals related to electrical activity of the heart of a subject includes a sensing device including an elongate member having a distal end configured for placement within a body lumen of a subject, and a proximal end configured to extend from the subject, an actuation portion carried by the elongate member and configured for placement within the body lumen, the actuation portion having a low-profile state for delivery within the body lumen and an expanded state, and one or more sensors disposed on the actuation portion, each including a contact surface configured to contact an interior wall of the body lumen, wherein the actuation portion is configured to cause the contact surface of each of the one or more sensors to contact a location on the interior wall of the body lumen to provide a signal component for producing one or more electrocardiogram signals.

The current invention provides an endotracheal tube fabricated with an array of electrodes disposed on an inflatable cuff on the tube. The array of electrodes includes multiple sense electrodes and a current electrode. The array of electrodes on the inflatable cuff is applied using a positive displacement dispensing system, such as a MicroPen&#xae;. A ground electrode is disposed on the tube approximately midway between the inflatable cuff and the midpoint of the endotracheal tube. The endotracheal tube is partially inserted into a mammalian subject's airway such that when the inflatable cuff is inflated, thereby fixing the tube in position, the array of electrodes is brought into close contact with the tracheal mucosa in relative proximity to the aorta. The endotracheal tube is useful in the measurement of cardiac parameters such as cardiac output.

The present invention is directed to holders for a sensor. The holders apply pressure to the sensor to prevent a venous blood signal without dampening the arterial blood signal and are optically opaque to shield ambient light from reaching the sensor.

A signal processing technique for estimating the frequency of a pulsatile signal (including but not limited to pulse oximetry signals) is disclosed. Each of the functions contained within a pre-selected set of functions is compared to the input signal at many different time-shifts, and the function/time-shift combination that best matches the input signal is selected. The frequency of the best-matching function is then used as the best estimate of the frequency of the input signal. Optionally, once a function has been selected, the rising portion of the selected function can be correlated in time to the rising portion of the input signal. Improved results can then be obtained by basing the oxygen saturation level calculations on samples taken from the rising portion of the input signal.

Signal processing for pulse oximetry

Disclosed is a brachytherapy seed deployment system for use in any of a variety of medical procedures such as radiation treatment of the prostate gland. The system includes at least two seeds secured together by a filament, which may be rigid or flexible. Also provided are methods of assembling the seeds and filaments, and methods of treating cancerous tissue using the seeds and filaments.

A holder for a sensor includes a body having a top wall and a side portion extending away from the top wall. The sensor is adapted to sense a parameter of an item. The top wall and the side portion of the body form an interior cavity. A flange is coupled to and extends away from an edge of the side portion. A pressure application portion is coupled to a surface of the interior cavity of the body and is adapted to apply force to the sensor when the holder is coupled to the surface of the item.

Preloaded sensor holder

An intubation device comprises an imaging conduit including an illumination conduit for delivering illumination to a distal end of the device and an image-receiving conduit for communicating images from the distal end of the device to the proximal end of the device. The device also comprises a flushing conduit for delivery of fluids and/or gases to the distal end of the device. The image conduit and the flushing conduit are attached at the distal end of the device. The distal end of the device can be manipulated by advancing the imaging conduit in an axial direction while maintaining the flushing conduit fixed in place. Furthermore, a length adjustment member is provided for adjusting the extent to which the distal end of the device extends beyond a distal end of an endotracheal tube which is inserted over the imaging and flushing conduits. The illuminating conduit and the image-receiving conduit terminate in separate ports at the distal end of the device. Furthermore, a substantial portion of the device is disposable, so that time consuming sterilization is not necessary.
