    摘要: System and methods for propagating error status over an error checking and correcting (ECC) protected channel. A first device receives data and an error status associated with the data. The first device generates check bits for the data based on a first ECC code and combines the check bits with the data to form one or more code words. The first device sends the code words across the channel where the first device inserts a triple error into a nibble of at least one codeword sent if the error status indicated an uncorrectable error. A second device connected to the channel receives the code words sent across the channel. The second device detects triple errors within a nibble of any code word and any other single error in the code word using a second ECC code, where the second ECC code is the first ECC code with columns for check bits inserted.

    摘要: A balloon catheter is provided having an expandable distal portion and balloon protector means comprising a first removable sleeve having a variable inner diameter to ease sliding the first sleeve over the balloon, and an optional second removable (outer) sleeve positioned over the inner sleeve, the second (outer) sleeve having a constrictive relationship with the first (inner) sleeve, said first and second sleeves being removed prior to use of the catheter. A stent delivery system is provided to facilitate introduction and placement of a stent, and includes a catheter having an expandable distal portion constructed and arranged for expanding the outer diameter of the catheter from a contracted state to an expanded state, said distal portion further comprising a balloon and at least one dam over which the balloon extends, and a stent positioned around the distal portion of the catheter around the balloon or gripper linear control device, said stent having a contracted condition, being sized in the contracted condition to closely surround the balloon in the contracted state, and being expandable to an expanded condition; a first removable (inner) sleeve in the region of the distal portion of the catheter positioned around the stent (and between the damns where the device comprises two dams), said first sleeve comprising a first end, a second end and a variable inner diameter to ease sliding the sleeve over the balloon and stent; an optional second removable (outer) sleeve positioned over the stent, first sleeve and at least one dam, said second (outer) sleeve having a constrictive relationship with the first (inner) sleeve, whereby when compressed by the outer sleeve, the inner sleeve will have an inner diameter approximately equal to or less than the outer profile of the collapsed balloon over the at least one dam, said first and second sleeves being removed prior to use of the stent delivery system and release of the stent by expansion of the balloon.

    摘要: An improved Y-adapter in which the lumen extending through the side arm is formed along the arc of a circle and smoothly merges into the lumen extending through the central arm, such that a catheter or guide wire can be smoothly inserted through the side arm of the Y-adapter into the central arm and then twisted and manipulated without distortion.

    摘要: A catheter assembly comprises at least one catheter shaft and a balloon. The catheter shaft comprises a substantially cylindrical portion and at least one tapered portion. The tapered portion forms an angle with the cylindrical portion of about 1 degree to about 25 degrees. At least one of the waists of the balloon is sealingly engaged to the tapered portion.

    摘要: The invention generally relates to internal (e.g., implantable, insertable, etc.) drug delivery devices which contain the following: (a) one or more sources of one or more therapeutic agents; (b) one or more first electrodes, (c) one or more second electrodes and (d) one or more power sources for applying voltages across the first and second electrodes. The power sources may be adapted, for example, to promote electrically assisted therapeutic agent delivery within a subject, including electroporation and/or iontophoresis. In one aspect of the invention, the first and second electrodes are adapted to have tissue of a subject positioned between them upon deployment of the medical device within the subject, such that an electric field may be generated, which is directed into the tissue. Furthermore, the therapeutic agent sources are adapted to introduce the therapeutic agents into the electric field. In another aspect, the therapeutic agent sources are polymeric regions that contain one or more types of ion-conductive polymers and one or more types of charged therapeutic agents. In yet another aspect, the therapeutic agent sources are polymeric regions that contain one or more types of electrically conductive polymers and one or more types of charged therapeutic agents.
