International Classification:

A61B 5/155

US Classification:

600573

Abstract:

A disposable, closed fluid sampling system for use with a medical conduit line, especially for taking blood samples from a pressure monitoring line. The conduit line has at least one fluid sampling site interposed between a distal segment of tubing and a proximal segment of tubing. The system includes a disposable subsystem having a bypass cannula adapted to engage the sampling site, a reservoir for drawing a prime volume of fluid past the sampling site, and a fluid sampling container. A 3-way stopcock may connect the reservoir, bypass cannula, and sampling vessel for controlling the sampling procedure. The bypass cannula may simultaneously place the subsystem into fluid communication with an inner chamber of the sampling site and exclude the proximal segment of the conduit line. Alternatively, a stopcock immediately adjacent the sampling site in the proximal segment may be utilized. A method of using the system includes attaching the disposable subsystem, opening the reservoir to the distal segment while excluding the proximal segment, drawing a prime volume of fluid into the reservoir, opening the sampling vessel to the distal segment and drawing a sample, re-infusing the prime volume into the distal segment, and removing and discarding the subsystem. The reservoir remains attached between the prime volume draw and re-infusion and is thus “closed.”

Abstract:

A method and apparatus for performing mitral valve chordal repair on a patient include attaching at least one filament to a mitral valve leaflet and to a papillary muscle. The length of filaments can be adjusted by adjusting tension in a filament or by altering the effective length of a filament by cutting filament strands or by moving an adjustment member along the length of the filaments.

Abstract:

In one embodiment according to the present invention, a stent is described having a generally cylindrical body formed from a single woven nitinol wire. The distal and proximal ends of the stent include a plurality of loops, some of which include marker members used for visualizing the position of the stent. In another embodiment, the previously described stent includes an inner flow diverting layer.
