  • Patent number: 8303644
    Abstract: Polymeric stents having fracture toughness and resistance to recoil after deployment are disclosed along with methods of manufacturing such stents. Improvements to mechanical characteristics and other improvements may be achieved by having polymer chains within individual stent struts oriented in a direction that is closer to or in line with the axis of the individual stent struts. The struts are connected to each other by hinge elements that are configured to bend during crimping and deployment of the stent. The hinge elements may be tangent or non-tangent to the adjoining struts so as to form W-shaped closed cells arranged in an offset brick pattern in which the size each W-shaped closed cell can be defined in part by a curvilinear length that is approximately 4.5 mm, which allows the stent to be crimped down to an OD of about 1.3 mm and expanded to an OD of at least about 3.5 mm.

  • Patent number: 8262702
    Abstract: An osteosynthetic clamp is provided for use in attaching a bone anchor to a support rod. The clamp comprises a carrier with a first portion adapted for connection to the anchor and with a second portion for connection to the rod. A clamping hook defines a bight in which the rod can be located and a head that passes through an aperture defined by the second portion of the carrier. The head of the hook passes through a collar, which is attached to the second portion of the carrier by engaging, complementarily shaped parts. These parts are defined respectively by the second portion of the carrier and by the collar and together form a joint permitting sliding translational movement of the collar relative to the carrier. A fastener can be secured to the head of the clamping hook and tightened in order to clamp the rod within the bight.

  • Patent number: 8252049
    Abstract: A method or workflow for heart valve replacement, or more precisely emplacement of a prosthetic heart valve, using minimally invasive procedures includes imaging of the patient's heart during the procedure using a multi-access articulated x-ray imaging robot that allows a radiation detector carried by the robot to be moved in arbitrary paths around a patient in order to generate multiple projection exposures of the relevant region of the patient during the procedure. The imaging system is used to generate two dimensional image data during movement of the catheter and prosthetic heart valve into place and to generate three dimensional image data of the prosthetic heart valve within the patient's heart. The two dimensional image data and the three dimensional image data are registered and superimposed for use in positioning of the prosthetic heart valve. Additional imaging may be performed once the prosthetic heart valve is in position.

  • Patent number: 8197538
    Abstract: An annuloplasty prosthesis including a sheath, an arcuate stiffening element, and an imaging element. The arcuate stiffening element is disposed within the sheath and defines discrete, first and second ends separated by a lateral spacing. The imaging element is disposed within the sheath along the lateral spacing. With this configuration, following implant to the valve annulus, the imaging element provides a mechanism for non-invasively evaluating a shape of the valve annulus, for example, via radiographic, echogenic and/or other image enhancing visualization techniques. In some embodiments, the annuloplasty prosthesis provides a radiographic, echogenic and/or other image enhanced image of a near entirety of the valve annulus.
