摘要： Improved atherectomy catheters and methods of use are disclosed. The catheter includes a flexible body with a longitudinal passage therethrough. A housing is mounted at the distal end, with an elongated aperture formed in a lateral side. A drive cable is disposed in the passage of the catheter body, and a working element is disposed in the housing, attached to the distal end of the drive cable. Passages and openings are provided for flowing blood into the housing and for flowing blood from a proximal to a distal side of the cutting blade. An impeller can be provided proximal to the cutting blade to impel blood into the housing and past the blade. Blood flows through the housing and past the blade so as to perfuse tissue downstream from the device.

摘要： Devices, systems and methods retain a native heart valve leaflet to prevent retrograde flow. The devices, systems, and methods employ an implant that, in use, rests adjacent a valve annulus and includes a retaining structure that is sized and shaped to overlay at least a portion of one or more native valve leaflets. The retaining structure retains the leaflet or leaflets it overlays, to resist leaflet eversion and/or prolapse. In this way, the implant prevents or reduces regurgitation. The implant does not interfere significantly with the opening of and blood flow through the leaflets during periods of antegrade flow.

摘要： A stent crimping apparatus for crimping a deformable radioactive stent onto a deployment device which includes a first jaw member defining a shielded first compression surface, and an opposed, second jaw member defining a shielded second compression surface oriented opposite the first compression surface. The first and second compression surfaces are adapted to collectively form an elongated guide bore formed for axial receipt of the deformable stent and the deployment device therein. To protect against exposure to the radioactive stent, a shield assembly is provided defining an opening into a bore therein which is formed and dimensioned for longitudinal receipt of the deformable stent in an uncrimped condition. A shield assembly defines an opening into the bore, and cooperates with the first and second jaw members to substantially prevent radioactive particles emitted by the radioactive stent from passing out of the crimping apparatus. An operating mechanism is operatively coupled to the first and second jaw members for selective movement between a loading condition and a crimping condition. In the loading condition, the uncrimped stent and the deployment device may be inserted through the opening and into the bore. In the crimping condition, the deformable stent is radially compressed onto the deployment device between the first and second compression surfaces.

摘要： Single-dose vials for liquid solutions (e.g., liquid medicaments) can be designed to be used in conjunction with a medication regimen. A single-dose vial may include a removable member that prevents a liquid solution from escaping, but also allows an individual (e.g., a patient or a medical professional) to readily administer the liquid solution. A single-dose vial could include one or more discrete capsules that include the same or different liquid solutions. For example, multiple capsules could be arranged within a vial so that different liquid solutions are simultaneously or sequentially ejected following removal of the removable member and application of pressure to the multiple capsules (e.g., due to the individual squeezing the vial). Multiple vials can also be connected to one another in a strip configuration, which allows the individual to more easily adhere to a medication regimen that requires multiple doses over a period of time.
