A Catheter Guidance Control and Imaging (CGCI) system whereby a magnetic tip attached to a surgical tool is detected, displayed and influenced positionally so as to allow diagnostic and therapeutic procedures to be performed is described. The tools that can be so equipped include catheters, guidewires, and secondary tools such as lasers and balloons. The magnetic tip performs two functions. First, it allows the position and orientation of the tip to be determined by using a radar system such as, for example, a radar range finder or radar imaging system. Incorporating the radar system allows the CGCI apparatus to detect accurately the position, orientation and rotation of the surgical tool embedded in a patient during surgery. In one embodiment, the image generated by the radar is displayed with the operating room imagery equipment such as, for example, X-ray, Fluoroscopy, Ultrasound, MRI, CAT-Scan, PET-Scan, etc. In one embodiment, the image is synchronized with the aid of fiduciary markers located by a 6-Degrees of Freedom (6-DOF) sensor. The CGCI apparatus combined with the radar and the 6-DOF sensor allows the tool tip to be pulled, pushed, turned, and forcefully held in the desired position by applying an appropriate magnetic field external to the patient's body. A virtual representation of the magnetic tip serves as an operator control. This control possesses a one-to-one positional relationship with the magnetic tip inside the patient's body. Additionally, this control provides tactile feedback to the operator's hands in the appropriate axis or axes if the magnetic tip encounters an obstacle. The output of this control combined with the magnetic tip position and orientation feedback allows a servo system to control the external magnetic field.

A system whereby a magnetic tip attached to a surgical tool is detected, displayed and positioned. A Virtual Tip serves as an operator control. Movement of the operator control produces corresponding movement of the magnetic tip inside the patient's body. Additionally, the control provides tactile feedback to the operator's hand in the appropriate axis or axes if the magnetic tip encounters an obstacle. The output of the control combined with the magnetic tip position and orientation feedback allows a servo system to control the external magnetic field by pulse width modulating the positioning electromagnet. Data concerning the dynamic position of a moving body part such as a beating heart offsets the servo systems response in such a way that the magnetic tip, and hence the secondary tool is caused to move in unison with the moving body part.

A system whereby a magnetic tip attached to a surgical tool is detected, displayed and influenced positionally so as to allow diagnostic and therapeutic procedures to be performed rapidly, accurately, simply, and intuitively is described. The tools that can be so equipped include catheters, guidewires, and secondary tools such as lasers and balloons, in addition biopsy needles, endoscopy probes, and similar devices. The tip position and orientation information and the dynamic body part position information are also utilized to provide a display that allows three dimensional viewing of the magnetic tip position and orientation relative to the body part.

A configurable firearm grip is provided in which a removable portion thereof can be selected by the user based on the user's preference. For example, backstraps of various forms, thicknesses, and textures can be fitted to a handgun depending upon if the handgun is to be used for target shooting, competitive target shooting, hunting, personal protection, or any other shooting activity, or to accommodate varying hand sizes. The backstrap can be removed and installed without the use of tools. Cooperative portions on the inner surfaces of the backstrap and the rearward portion of the grip facilitate the registration of the backstrap with a fixed portion in preparation for the insertion of a locking element. The backstrap is able to be secured on the fixed grip portion of the handgun with one hand while the locking element is inserted through the backstrap and the fixed grip portion with the other hand.

An electrochemical cell including a folded electrode layer and a folded separator, a battery including the electrochemical cell, and methods of forming the electrochemical cell and battery are disclosed. The electrode layer is folded in a first direction and the separator is folded in a second direction, such that the first direction and second direction are orthogonal each other.

A vascular suturing device is disclosed which includes an elongated tubular body defining opposed proximal and distal end portions and having a longitudinal axis extending therethrough, the body including an inner tubular member, an outer tubular member and a central tubular member disposed between the inner and outer tubular members. The inner tubular member and the central tubular member are mounted for movement relative to the outer tubular member about the longitudinal axis of the body for sequentially driving a pair of suture needles through the wall of a blood vessel to close an incision formed therein. A vascular dilator having a tapered distal tip portion is slidably supported within the inner tubular member and is dimensioned to extend beyond the distal end of the inner tubular member for positioning the suturing device at the incision in the wall of the blood vessel. The dilator is configured to move axially between an extended position and a retracted position. A biasing element and a retaining pin are associated with a proximal end of the dilator. The biasing element is adapted and configured for urging the dilator in the retracted position and the retaining pin is position so as to secure the dilator in the extended position.

The present invention is for a high performance data cable which has an interior support or star separator. The star separator or interior support extends along the longitudinal length of the data cable. The star separator or interior support has a central region. A plurality of prongs or splines extend outward from the central region along the length of the central region. Each prong or spline is adjacent with at least two other prongs or splines. The prongs or splines may be helixed or S-Z shaped as they extend along the length of the star separator or interior support. Each pair of adjacent prongs or splines defines grooves which extend along the longitudinal length of the interior support. At least two of the grooves have disposed therein an insulated conductor. The interior support can have a first material and a different second material. The different second material forms an outer surface of the interior support.

Provided is a process for producing a glass-like carbon deformed molded article having a deformed section (typically, an elliptical section or a section composed of partial circles and linear portions), such as a glass-like carbon member in a deformed pipe form or a bent pipe, with relative ease and a good dimensional accuracy. The process comprises the step of molding a thermosetting resin to yield a thermosetting resin molded article, the step of deforming the thermosetting resin molded article plastically in the state that the article is heated, so as to yield a thermosetting resin deformed article, and the step of carbonizing the resultant thermosetting resin deformed article.
