    摘要: The various aspects of the invention pertain to devices and related methods for treating heart conditions, including, for example, dilatation, valve incompetencies, including mitral valve leakage, and other similar heart failure conditions. The devices and related methods of the present invention operate to assist in the apposition of heart valve leaflets to improve valve function. According to one aspect of the invention, a method improves the function of a valve of a heart by placing an elongate member transverse a heart chamber so that each end of the elongate member extends through a wall of the heart, and placing first and second anchoring members external the chamber. The first and second anchoring members are attached to first and second ends of the elongate member to fix the elongate member in a position across the chamber so as to reposition papillary muscles within the chamber. Also described herein is a method for placing a splint assembly transverse a heart chamber by advancing an elongate member through vasculature structure and into the heart chamber.

    摘要: An aortic cannula tip for reintroducing blood into the blood stream via the aorta. The tip creates a soft flame-shaped flow pattern that reduces the chances of dislodging atheromatous or adherent thromba from the inside surfaces of the aorta. A gentle tapered shape allows the tip to penetrate a small incision made in the aorta without causing undo trauma or risk of tearing. The tip includes a circumferential ridge that allows the tip to be rotated and/or pivoted while in the aorta without breaking a seal formed between the ridge and the aortal wall. A secondary port provides access to a second lumen useable to deploy an intraaortic filtration system.

    摘要: There is described a sensor device which comprises light source means for emitting a light beam, photodetector means for receiving the light beam after passing through or being reflected within living tissue and arranged to provide signals corresponding to the intensities of the respective wavelength of light received by the photodetector means characterised in that the sensor device measures blood oxygen saturation. The device can be used in conjunction with a conventional pulse oximeter. There is also described a method of measuring blood oxygen saturation.

    摘要: A woven vascular graft having a texturized outer surface to promote tissue ingrowth into the graft. The outer surface of the graft is equipped with a plurality of threads that are woven into, and extend from, the outer surface. The threads may be arranged in rows, lines or a geometric pattern. Alternatively, the threads may be towel-like. Such towel-like threads may be arranged in the form of a cuff at each end of the graft, or may cover larger portions of the exterior of the graft. The graft may be equipped with only one texture, or with a plurality of different textures.

    摘要: An annuloplasty band and method of implantation. The band is shaped and sized to avoid the adjacent aortic valve structure and better protects against dehiscence along the muscular mitral annulus. The band is asymmetric and when implanted spans more around the side of the mitral annulus having the posterior commissure than the side with the anterior commissure. The band has a saddle shape with a posterior upward bow centered on a minor axis of the mitral annulus, and a span extending clockwise therefrom is longer than a span extending counter-clockwise. The longer span may be 150° while the shorter span extends 90°. A set of rings may have different saddle profiles and different plan view shapes for different sized bands. A method includes implanting so that the band extends over the posterior leaflet and a short distance past the posterior commissure outside of the anterior leaflet.
