Intra-aortic renal drug delivery catheter

A catheter for delivering a therapeutic or diagnostic agent to a branch blood vessel of a major blood vessel, generally comprising an elongated shaft having at least one lumen in fluid communication with an agent delivery port in a distal section of the shaft, an expandable tubular member on the distal section of the shaft, and a radially expandable member on the tubular member. The tubular member is configured to extend within the blood vessel up-stream and down-stream of a branch vessel, and has an interior passageway which is radially expandable within the blood vessel to separate blood flow through the blood vessel into an outer blood flow stream exterior to the tubular member and an inner blood flow stream within the interior passageway of the tubular member. The radially expandable member is located down-stream of the shaft agent delivery port, and has an expanded configuration with an outer diameter larger than an outer diameter of the tubular member. The expanded radially expandable member is configured to decrease the blood flow in the outer blood flow stream down-stream of the branch vessel. The catheter provides for delivery of an agent to a branch vessel of a major vessel, and continuous perfusion of the major blood vessel. Another aspect of the invention is directed to methods of delivering a therapeutic or diagnostic agent to one or both kidney's of a patient.

Low profile vascular filter system

A removable, low profile, vascular filter system for capture and retrieval of emboli while allowing continuous perfusion of blood, comprising a guidewire having proximal and distal markers, a filter delivery and deployment system, having an outer member and an inner member, and a filter removably attached near the distal end of the inner member. The filter comprises proximal and distal basket sleeves which position the filter between the proximal and distal markers on the guidewire, after the guidewire is in position past the vessel occlusion. The guidewire placement prior to filter delivery may facilitate access to the interventional site, especially through tortuous anatomy. Also, retrievability of the filter from the wire may avoid loss of guidewire position, which may occur following removal of filters permanently attached to guidewires.

Expandable perfusion balloon

InactiveUS20110264039A1Increased durabilityIncrease lumen sizeStentsBalloon catheterContinuous perfusionRapid pacing
A balloon catheter for dilation of stenotic tissue within a tubular member of the body such as a blood vessel provides fluid flow such as blood flow through the balloon while it is being inflated and after it has been inflated. For valvuloplasty applications or for predilitation prior to a TAVI procedure the balloon is placed across the stenotic aortic valve leaflets and inflated to push the leaflets aside to create a greater blood flow area or allow improved subsequent passage of the large TAVI catheter across the stenotic aortic valve leaflets. As the balloon is inflated in diameter, it is required to reduce in length; this length reduction causes a braided inner tubing to also reduce in length. The braided inner tube is thereby required it to increase in diameter during the balloon inflation and create a suitably large blood flow path through the inner tubing. The continuous perfusion through the inner tubing of the balloon allows greater balloon inflation times, improved valvular dilation, and obviates the need for rapid pacing during the valvuloplasty procedure.

Perfusion chamber for electrophysiological testing of oocytes

A perfusion chamber includes a porous oocyte support structure. A continuously sloped top surface and a receiving well in the support structure entrap the underside of the oocyte, thereby localizing the cell in a predetermined fixed position within the reach of dedicated voltage-clamp microelectrodes. A test solution is delivered continuously at the top of the chamber, above the oocyte, and withdrawn from the bottom of the chamber, below the oocyte. The porosity of the support material enables the continuous perfusion of test solution around the membrane of the oocyte, including its bottom portion that is held firmly in contact with the holding well. The geometry of the holding well is selected such as to ensure the automatic and precise placement of the oocyte by gravity and to optimize the pressure distribution over its membrane, thereby minimizing the probability of rupture or other damage to the cell. The entire top surface of the support structure is sloped inward toward the substantially central well, and the bottom of the well is contoured to conform to the shape of an oocyte of average size.
