摘要： The present invention provides an aortic valvuloplasty catheter which, in one preferred embodiment, has a tapered distal balloon segment that anchors within the left ventricle outflow track of the patient’s heart and a rounded proximal segment which conforms to the aortic sinuses forcing the valve leaflets open. In addition, this embodiment of the valvuloplasty catheter includes a fiber-based balloon membrane, a distal pigtail end hole catheter tip, and a catheter sheath.

摘要： A temporary pacing lead has an atraumatic curled distal region with multiple cathodes and distal pressure measurement to allow positioning and repositioning within the heart chamber without fluoroscopic or echo guidance. The curled distal region provides definite contact with two opposing walls of the ventricular chamber to ensure electrical signal capture without trauma to the endocardial surface. A stylet located in the pacing lead lumen assists in introducing, placing, and removing the pacing lead from the heart. The flexible distal region provides safe removal of the temporary lead following completion of use.

摘要： Pigtail catheters for measuring a pressure gradient across a bodily narrowing are disclosed. A pigtail catheter can comprise a proximal shaft segment (102) and a distal shaft segment (104). The proximal shaft segment can include double lumen tubing defining a proximal pressure lumen and a non-coaxial, distal pressure lumen. In an example, the distal pressure lumen has a generally circular cross- sectional shape, and the proximal pressure lumen has a generally crescent or kidney cross-sectional shape that wraps partially around the distal pressure lumen. The distal shaft segment can include at least one distal orifice (124) positionable distal to the bodily narrowing and at least one proximal orifice (122) positionable proximal to the bodily narrowing. Each orifice can have a diameter of at least about 0.46 mm for example.

摘要： A trans-atrial septal catheter system for delivery of a steerable sheath into the left atrium contains three components. The first component is a three-segmented needle-guide wire (10) composed of a distal needle (12) designed to flex sharply in relation to the conjoined looped guide wire segment (14) after fossa ovalis puncture and needle advancement. The distal guide wire loops are advanced into the left atrium maintaining the angled needle in a central location relevant to the loops for preserving an atraumatic position while stabilizing the loops in the left atrium. The elongated proximal extra stiff guide wire segment (16) is conjoined to the looped segment which crosses the fossa ovalis and extends proximally to become externalized to the femoral vein. This segment is extra stiff and significantly elongated to permit catheter and device exchanges. The guide wire serves as a support rail over which the dilator (108) and sheath (100) can be advanced into the left atrium. This transseptal system is uniquely forward looking and permits cautious and iterative delivery of the dilator into the fossa ovalis for "tenting" by way of a proximal sheath activator that interacts with the dilator. The proximal externalized GW is then advanced to permit puncture of the fossa ovalis. After puncturing a precise location of the fossa ovalis, the needle and coiled guide wire loops are further advanced into the left atrium. With the proximal activator (112), the dilator is advanced across the fossa ovalis into the left atrium using single-handed maneuvering for separate dilator advancement and steering of the sheath by way of turning or actuating the sheath handle.
