A multi-headed catheter for fluid delivery and a method of placing a multi-headed catheter for fluid delivery are provided. The multi-headed catheter includes a first tube extending along an axis, wherein the first tube has at least one exit hole provided at a distal end of the first tube to define a perfusion section of the first tube; and a second tube extending along the axis, wherein at least a portion of the second tube is disposed within the first tube, wherein the second tube has at least one exit hole provided at a distal end of the second tube to define a perfusion section of the second tube. The distal end of the second tube is configured to exit said first tube at an opening provided along a wall of the first tube. The perfusion sections of the first tube and the second tube can be independently placed to deliver fluid to distinct anatomical areas within a surgical wound site.

The invention relates to an arrangement (10) for implementing kissing balloons simulating a bifurcated vessel, comprising a first catheter (4) having a first inflatable balloon (6) at or near its distal portion, a second catheter (7) having a second inflatable balloon (7a) at or near its distal portion, wherein the first catheter comprises a holding element (4) provided on the said first balloon (6), the said holding element (4) being adapted for: allowing the distal portion of the second catheter (7) to pass there through; affixing the second catheter (7) in a proximal vicinity to the first catheter (4) so that, in use, respective facing surfaces of the inflated first balloon (6) and the inflated second balloon (7a) touch each other.

A multi-purpose balloon catheter includes a catheter having a proximal end portion, a central portion and a distal end portion, a plurality of lumens associated with the catheter extending from the proximal end portion, and a plurality of inflatable balloons positioned in the central portion and/or the distal end portion. Each of the plurality of inflatable balloons is communicatively associated with a corresponding one of the plurality of lumens, the plurality of inflatable balloons being selectively inflated and deflated to position and stabilize the catheter in a cavity for delivery of a treatment. The catheter can include an extraction point associated with a lumen to remove fluids and material from the cavity, and a connector associated with a corresponding lumen adapted to selectively receive one or more of a liquid saline solution, a fluid medium, or a radioactive isotope provided to a corresponding lumen for delivery of the treatment.

Methods of using a medical device comprising a tube having first segment comprising a primary opening at the proximal end nearest an external termination device; and a second segment comprising a secondary opening at the distal end; and a side-hole dividing the first segment and the second segment, wherein the internal diameter of the first segment is greater than the internal diameter of the second segment, and the tube has no pre-formed curved configuration. The first segment extends from the primary opening to the side-hole and the second segment extends from the side-hole to the secondary opening. The side-hole and first segment form a non-support lumen, and the second segment forms a support lumen. The support lumen is effective to provide stability to the non-support lumen of the tube, to anchor the tube within an anchor area, and to prevent prolapse of the medical device elements due to a counterforce against the tube by the second device(s) being delivered through the tube to a more distal location of a target area; and to facilitate placement of the second medical device into the target area.

The present disclosure provides an apparatus including a first tubular housing including a first exit port and a second tubular housing including a second exit port. The apparatus also includes a third tubular housing coupled to at least one of the first tubular housing and the second tubular housing such that each of the first tubular housing, the second tubular housing, and the third tubular housing are fixed with respect to one another. The apparatus also includes a first catheter including a first plurality of outlets and is configured to be positioned at least partially within the first tubular housing. The apparatus also includes a second catheter including a second plurality of outlets and is configured to be positioned at least partially within of the second tubular housing. The apparatus also includes a pressure transducer line positioned in the third tubular housing and a pressure transducer coupled to the pressure transducer line.

A multi-purpose balloon catheter includes a catheter having a proximal end portion, a central portion and a non-branching distal end portion, a plurality of lumens associated with the catheter extending from the proximal end portion, and a plurality of inflatable balloons positioned in the central portion and/or the non-branching distal end portion. Each of the plurality of inflatable balloons is communicatively associated with a corresponding one of the plurality of lumens, the plurality of inflatable balloons being selectively inflated or deflated to position and stabilize the catheter in a cavity for delivery of a medical treatment. The catheter can include an extraction point associated with a lumen to remove fluids and materials from the cavity, and a connector associated with a corresponding lumen adapted to selectively receive one or more of a fluid medium or a radioactive isotope provided to a corresponding lumen for delivery of the medical treatment.

A device includes a medusa wire group with at least three separate wires slidably received in a vascular catheter. The multiple wires of the medusa wire group maximize the chances of at least one wire entering a target branch vessel during an attempt to achieve access. Entry into the branch vessel may then be gained by advancing the vascular catheter over the at least one wire that successfully entered the branch passageway.

A system for treating a bifurcation includes a first radially expandable stent and a second radially expandable stent. The first stent has a side hole and a plurality of lateral elements extending from the side hole. The second stent has a plurality of axial elements extending away from the proximal end of the second stent. The axial elements of the second stent interdigitate with the lateral elements of the first stent when both stents have been expanded.
