  • Patent number: 8551128
    Abstract: The invention provides a rotational atherectomy system, device and method comprising a flexible, elongated, rotatable drive shaft with an abrasive section within a pre-curved section of the drive shaft. The device may further comprise a concentric or eccentric enlarged diameter section that is at least partially covered with abrasive material to comprise the abrasive section. The abrasive section may further comprise an abrasive crown or burr mounted to the drive shaft. The pre-curved drive shaft allows smaller diameter and/or massive abrasive regions to be used while sweeping larger diameters during high-speed rotation. The pre-curved region is substantially straightened for insertion into vasculature and placement adjacent stenosis by insertion of the guide wire. Removal of guide wire proximally from the pre-curved region allows the drive shaft to return to its pre-curved form for ablation. Reinsertion of the guide wire beyond the pre-curved region straightens the drive shaft for ease of removal.

  • Patent number: 8535368
    Abstract: A stent loading and deployment device includes an outer elongate tubular member having opposed proximal and distal ends and an inner elongate tubular member having opposed proximal and distal ends and slidably disposed within the outer tubular member. When the distal ends of the outer tubular member and the inner tubular member are axially aligned, a stent deployment region is defined there in between. The device further includes a stent loading member having opposed proximal and distal ends and slidably disposed between the outer tubular member and the inner tubular member. The distal end of the stent loading member is slidable to a distal position past the distal end of the outer tubular member for receiving a stent and is further slidable toward the proximal end of the outer tubular member to a location past the stent deployment region for disengagement of a stent from the stent loading member.

  • Patent number: 8529580
    Abstract: The surgical grasping instrument having U-shaped jaws has a pair of handles connected to a pair of U-shaped jaws by a pair of elongated arms. The lower jaw is rigidly connected to the anterior end of the lower elongated arm. The upper jaw is pivotally connected to the anterior ends of the upper and lower elongated arms. The upper and lower arms are held together in sliding contact so that sliding the upper arm pivots the upper jaw. Both handles have finger loops. The rearward handle is rigidly attached to the lower arm, and is pivotally attached to the forward handle. The forward handle is attached to the upper arm by a ball and socket joint so that pivoting the handles pivots the upper jaw. The U-shaped jaws are designed to grasp round or semi round objects, such as a tympanostomy tube.

  • Patent number: 8523847
    Abstract: Handpieces which comprise characteristic data storage systems electronically storing characteristic data, devices comprising these handpieces, methods of characterizing the device components, and methods of adjusting the device components based on stored characteristic data are described. The handpieces can be repeatedly connected to, disconnected from, and reconnected to an optical energy system comprising at least one optical energy source and at least one controller by a treatment provider. When the handpieces are connected to an optical energy source and a controller, the component characteristic data is accessed and used to adjust one or more of the components in order for the components to function together within a pre-determined tolerance. Once the components are connected and adjusted, the device can be used to provide an optical energy based medical and/or cosmetic treatment to a tissue such as, for example, human skin.

  • Patent number: 8518052
    Abstract: The present disclosure concerns a delivery system for delivering a medically useful payload through the vasculature to a site of interest in the patient's body. The medically useful payload may be a therapeutic device, such as a stent, and it may be a diagnostic tool, such as an imaging device. Owing to its structural attributes, the presently-inventive delivery system is well suited for carrying medical payload to and through vessel curvature and to branched regions (i.e., bifurcations) in same. Also, the device is well-suited to traveling through a vessel over a guiding element, such as a guidewire, which itself exhibits curvature.

  • Patent number: 8518066
    Abstract: An ultrasonic horn for use with an ultrasonic surgical hand piece including a resonator comprises a contacting annulus having a plurality of angled lands. The lands are alternated around the annulus such that adjacent lands have opposite angles. As a result of the adjacent angled lands, a shear stress field is developed in contacted tissue due to the promotion of refracted longitudinal ultrasonic waves propagating in different directions at the interface to the coupled tissue. The shear stress field enhances the fragmentation and removal rate of fibrous, elastic, and tenacious tissue. The horn is hollow permitting suction to be applied to the tissue for controlling tissue contact with the lands.

  • Patent number: 8496651
    Abstract: A system and method are provided for an ophthalmic surgical procedure to provide a refractive correction for an eye. Specifically, the procedure is indicated when the desired refractive correction “dreqd” exceeds the capability of a correction achievable when corneal tissue is only ablated. In accordance with the present invention, an optimized refractive correction “d1” is accomplished by the ablation of corneal tissue (e.g. by a PRK or LASIK procedure). The optimized correction is then followed by a complementary refractive correction “d2” wherein stromal tissue is weakened with Laser Induced Optical Breakdown (LIOB). Together, the optimized refractive correction (ablation) and the complementary refractive correction (LIOB) equal the desire refractive correction (dreqd=d1+d2).

  • Patent number: 8480697
    Abstract: A device capable of capturing and facilitating the removal of a thrombus in blood vessels (or stones in biliary or urinary ducts, or foreign bodies) uses a soft coil mesh with the aid of a pull wire or string to engage the surface of a thrombus, and remove the captured thrombus. The soft coil mesh is formed by an elongated microcoil element that forms the helical elements of a macrocoil element. The microcoil element provides a relatively elastic effect to the helical elements forming the macrocoil and allows for control of gripping forces on the thrombus while reducing non-rigid contact of the device with arterial walls. The use of multiple coil mesh elements, delivered through a single lumen or multiple lumens, preferably with separate control of at least one end of each coil, provides a firm grasp on a distal side of a thrombus, assisting in non-disruptive or minimally disrupted removal of the thrombus upon withdrawal of the device.

  • Patent number: 8460363
    Abstract: Expandable medical implants for maintaining support of a body lumen are disclosed. These implants comprise an axially-radially nested, diametrically expandable, moveable vascular device for enlarging an occluded portion of a vessel. The device can be configured to allow for motion such as translating and/or slide and lock. One advantage of the axially-radially nested stent is that it maintains the expanded size, without significant recoil.
