A catheter has single axis sensors mounted directly along a portion of the catheter whose position/location is of interest. The magnetic based, single axis sensors are on a linear or nonlinear single axis sensor (SAS) assembly. The catheter includes a catheter body and a distal 2D or 3D configuration provided by a support member on which at least one, if not at least three single axis sensors, are mounted serially along a length of the support member. The magnetic-based sensor assembly may include at least one coil member wrapped on the support member, wherein the coil member is connected via a joint region to a respective cable member adapted to transmit a signal providing location information from the coil member to a mapping and localization system. The joint region provides strain relief adaptations to the at least one coil member and the respective cable member from detaching.

A patch and sensor assembly has a biosensor housed in a reusable portion that connects to a mapping and localization system (MLS) via biosensor wires. A disposable portion has an electrode layer through which signals are transmitted to the MLS via ACL wires. The biosensor and ACL wires extend through a single cable exiting the reusable portion. The disposable portion includes an adhesive layer for adhering the electrode layer to a patient, on the electrode layer, and an engagement element for detachably receiving at least a portion of the housing of the reusable portion. The reusable portion includes a housing in which the biosensor has biosensor wires that exit the reusable portion. The housing is also adapted to carry and/or provide support to an ACL contact member responsive to the electrode layer of the disposable portion, and ACL wires that exit the reusable portion.

A medical device control handle has a first actuation assembly and a second actuation assembly, wherein each assembly has a shaft that is axially aligned but not rotationally coupled with the other shaft. The first actuation assembly includes a first actuation member and a clutch mechanism having a friction disk for generating frictional torque in rendering the first actuation member self-holding. The first actuation member has a cam portion adapted to impart translational motion and rotational motion for disengaging the clutch mechanism upon pivotation of the first actuation member, thus allowing rotation of the first shaft to manipulate a feature of the medical device, for example, deflection. The second actuation assembly includes a second actuation member and a translating member that is responsive to rotation of the second shaft so as to manipulate another feature of the medical device. The second actuation member is also self holding.

Intravascular devices, systems, and methods are disclosed. In some embodiments, a guidewire system for treating a patient includes an internal sensor mount having a body and a first cutout extending through a wall of the body; a core wire secured to the internal sensor mount; a sensor assembly for detecting a physiological characteristic of a patient secured to the internal sensor mount; an external housing disposed about the internal sensor mount and including an opening in communication with the cutout of the internal sensor mount; a proximal flexible member secured to at least one of the internal sensor mount and the external housing; a first distal flexible member secured to at least one of the internal sensor mount and the external housing; and at least one conductor electrically coupled to the sensor assembly and extending proximally beyond the internal sensor mount through the proximal flexible member.

Lumen-traveling biological interface devices and associated methods and systems are described. Lumen-traveling biological interface devices capable of traveling within a body lumen may include a propelling mechanism to produce movement of the lumen-traveling device within the lumen, electrodes or other electromagnetic transducers for detecting biological signals and electrodes, coils or other electromagnetic transducers for delivering electromagnetic stimuli to stimulus responsive tissues. Lumen-traveling biological interface devices may also include additional components such as sensors, an active portion, and/or control circuitry.

The presence or absence of objects tagged with transponders may be determined in an environment in which medical procedures are performed via an interrogation and detection system which includes a controller and a plurality of antennas positioned along a patient support structure. The antennas may be positioned along an operating table, bed, mattress or pad, sheet, or may be positioned on a drape, or shade. Respective antennas may successively be activated to transmit interrogation signals. Multiple antennas may be monitored for responses from transponders to the interrogation signals. For example, all antennas other than the antenna that transmitted the most recent interrogation signal may be monitored. Antennas may be responsive to force, a signal indicative of such force being produced. A wireless physiological condition monitor may detect patient physiological conditions and wirelessly transmit signals indicative of such.

The present invention relates to a medical method of managing a cerebrovascular insult, the method comprising the following steps in this order: a) placing a patient on a patient support unit; b) positioning a mobile tomographic imaging system in a predetermined position relative to the patient support unit with the patient placed on the patient support unit; c) imaging at least part of the patient's brain using an imaging unit of the tomographic imaging system, the imaging comprising in particular generating an image describing the functioning of the patient's blood vessel system; d) determining, in dependence on the result of the imaging, whether the patient support unit should be rotated relative to the tomographic imaging system with the patient placed on the patient support unit so that the patient is free of the imaging unit in order to conduct a medical intervention on the patient's blood vessel system, or whether the patient support unit may remain in its position relative to the tomographic imaging system with the patient placed on the patient support unit.

Disclosed is an ECG electrode lead wire connector which provides improved electrical and mechanical coupling of the ECG electrode press stud to the lead wire and is suitable for use during imaging procedures such as, without limitation, CT scans or MRI. The connector assembly includes a housing having.
