A device for filtering emboli from blood flowing through a lumen defined by the walls of a vessel in a patient's body, comprising: a filter element being expandable from a collapsed configuration when the filter element is restrained to an expanded configuration when the filter element is unrestrained, and an elongate support member, the filter being carried on a portion of the elongate support member, wherein the filter element has proximal and distal portions and a central portion, the filter element having a shape in the expanded configuration which defines a cavity having a proximal facing opening, and wherein the proximal portion of the filter element comprises a radiopaque element in the form of a discontinuous loop extending around a portion of a perimeter of the proximal facing opening, the discontinuous loop having a gap and the gap being proximate to the elongate support member.

Embolic protection devices having radiopaque elements

The invention provides an embolic protection device for removing emboli from a blood vessel in a patient's body. The device comprises an elongate host element, an embolic protection element having a collapsed configuration and an expanded configuration, and a flexible tether connected to a distal end of the host element and to a proximal portion of the embolic protection element. The tether allows the host element to move axially and laterally relative to the embolic protection element over a limited range of motion when the embolic protection element is in an expanded configuration. The embolic protection device has a landing zone of 4 cm or less.

Embolic protection devices having short landing zones

A catheter system including a collection member having an occlusion member and collection ports. At least one collection port being located distal to the occlusion member, and least one collection port being located proximal to the occlusion member.

Catheter with distal and proximal ports

A device for filtering emboli from blood flowing through a lumen defined by the walls of a vessel in a patient's body. The device including a filter element being expandable from a collapsed configuration when the filter element is restrained to an expanded configuration when the filter element is unrestrained, and an elongate support member, the filter being carried on a portion of the elongate support member. The filter element has proximal and distal portions and a central portion, the filter element having a shape in the expanded configuration which defines a cavity having a proximal facing opening, and the proximal portion of the filter element includes a radiopaque element in the form of a discontinuous loop extending around a portion of a perimeter of the proximal facing opening, the discontinuous loop having a gap and the gap being proximate to the elongate support member.

A remote sensing catheter system including an injection catheter and a collection catheter. In one method of use, an external sensor of the system determines the timing of operation of the collection catheter. In another method of use, a sensor determines the volume of medium in the injection.

Remote sensing catheter system and methods

Catheter having a first elongate tubular body having a lumen, a second elongate tubular body having a lumen, and an elongate member. The elongate member joins the first and second elongate tubular bodies. The first tubular body is fixedly attached on the distal portion of the elongate member, and the second elongate tubular body is disposed on the elongate member is slidable along a portion of the elongate member. The second elongate tubular body can be in a first position so that the first and second tubular bodies are not adjacent to each other and can be in a second position so that the first and second tubular bodies are adjacent to each other. The catheter may have a locking mechanism that can lock the first and second elongate tubular bodies to each other so that the lumens of the first and second elongate tubular bodies form one continuous lumen.
