Assignee:

Tyco Healthcare Group LP - Mansfield MA

International Classification:

A61M 29/00

US Classification:

606200

Abstract:

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.

International Classification:

A61M 29/00

US Classification:

606200

Abstract:

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.

Assignee:

EV3 INC. - Plymouth MN

International Classification:

A61M 29/00

US Classification:

606200

Abstract:

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.

US Classification:

600424, 604 9601, 600547

Abstract:

A sensing system including a collection catheter and a sensing device. The sensing system can be used in determining an optimal location of a collection catheter for the removal of a medium from coronary circulation. The sensing system can also be used in determining the optimal time for the collection of blood containing a medium. The sensing system can further be used to maintain a baseline flow rate through at least a portion of the coronary circulation system during a medical procedure.
