摘要： The present invention provides an improved drive shaft for use in a catheter system having a rotating imaging or interventional work element. A drive shaft according to the present invention is formed at least in part of a material having super elastic properties. This material provides an advantageous combination of column strength and torsional rigidity with the ability to sustain substantial bending without permanent deformation. Preferred embodiments are formed as hollow tubes to allow electrical conducting wires to be disposed within the body of the drive shaft. Some embodiments combine relatively rigid proximal segments with relatively flexible distal segments to allow for entry of the work element into narrow and twisting regions of a patient's vascular system.

摘要： The present invention provides improvement usable with an intravascular catheter having a single common distal lumen with a reduced profile connected to two or more proximal lumens. The catheter will be loadable over a guidewire into a region of interest within a patient's vascular system. According to one aspect of the present invention, means are provided to ensure that the guidewire enters into a desired one of the proximal lumens. In a preferred embodiment, a special tool is provided to achieve this. According to a second aspect of the present invention, the catheter is provided with a proximal housing and an axially expandable member to shield the rotating parts at the proximal end of the catheter and to allow for convenient movement of a work element within the catheter body.

摘要： An electrical connector is described. In one implementation, the connector includes a female portion including one or more electrical contacts and a male portion including one or more electrical contacts. The female portion and the male portion each have a self-orientating geometry that allows the male portion to be mated with the female portion in any rotational position along 360 degrees of rotation. When mated, the electrical contacts of the female portion mate with corresponding one or more electrical contacts of the male portion to form one or more electrical connections between two electronic components.

摘要： Described herein are imaging catheter system. In an exemplary embodiment, a catheter comprises a handle assembly having distal and proximal ends, a catheter sheath connected to the distal end of the handle assembly, and an elongated flexible tube connected to the proximal end of the handle assembly. The catheter further comprises an imaging core slidably received within the catheter sheath, the handle assembly and the elongated tube. The imaging core also includes a slide member, e.g., knob, extending from the imaging core and passing through an elongated slot in the handle assembly, allowing a physician to manually pullback and advance the imaging core within the catheter by sliding the slide member back and forth. Preferably, the elongated tube is long enough so that the motor drive coupled to the proximal end of the catheter is kept outside the sterile field during the imaging procedure.

摘要： A recessed luminaire includes a housing with one or more vents. The one or more vents may be coupled to a ventilation system so that the luminaires can provide ventilation as well as illumination. The housing supports a potentially flammable diffuser with one or more fusible links. When subjected to elevated temperatures, at least a portion of the one or more fusible links will soften so the diffuser may drop down.

摘要： The present invention provides self-aligning rotational connectors. In an non-limiting embodiment, a catheter system comprises a catheter connectable to a drive unit. The catheter includes a rotator, and at least one orientating feature extending proximally from the rotator, and configured to be inserted into an orienting slot of a shaft connector of the drive unit. When the orienting feature is inserted into the slot of the shaft connector, the slot transmits torque from the shaft connector to the orientating feature, and therefore the rotator of the catheter. Electrical contacts are provided on the rotator and the shaft connector, wherein the contacts of the rotator are properly aligned with and engage the contacts of the shaft connector. Further, the shaft connector has a slopping surface that slops downward into the slot for automatically aligning the rotator rotationally with the shaft connector during insertion of the catheter into the drive unit.

摘要： A catheter assembly for an intravascular ultrasound system includes an ultrasound transducer disposed in an image device housing within a lumen of a catheter. The ultrasound transducer transforms applied electrical signals to acoustic signals within a frequency bandwidth centered at an operational frequency and having variable electrical impedances over one or more frequencies within the bandwidth. A distal drive cable is coupled to the imaging device housing. A connector housing couples the distal drive cable to a proximal drive cable. A transducer conductor electrically couples the transducer to a proximal end of the catheter. At least one tuning element is electrically coupled to the transducer conductor. The at least one tuning element matches electrical impedances of the transducer conductor to the ultrasound transducer over at least a subset of frequencies within the frequency bandwidth of the ultrasound transducer.
