Abstract
Transradial access of mammalian vasculature enhances and renders novel approaches to the heart, brain and other associated organ systems less fraught with risk and more appropriate for ageing populations and challenging vessel morphologies, inter alia. Cerebral access is emphasized.
Claims34
A catheter that is capable of radial passage through the cardiovascular system, and capable of passage to the lumen of the aortic arch, wherein the catheter comprises a proximal end and a distal end, and wherein the proximal end to the distal end of the catheter comprises a lumen, and wherein the catheter comprises:
- (i) An optional hub that comprises the proximal end,
- (ii) A first straight segment, that is not tapered,
- (iii) A second straight segment that is tapered,
- (iv) Optionally, a third straight segment, that is not tapered,
- (v) A third straight segment, that is not tapered,
- (vi) A first curved segment,
- (vii) A second curved segment, and
- (viii) Optionally, an S-shaped region consisting of a first curved segment that resides in this S-shaped region, and a second curved segment that resides in this S-shaped region, wherein the first curved segment provides the bottom half of an S-shape, and the second curved segment provides the top half of the S-shape, wherein the bottom half is relatively proximal and the top half is relatively distal.
An alternate design catheter, as defined herein, where in the alternate design catheter comprises a tapered straight region that is about six centimeters long, and that does not include any tapered straight region that is between about two centimeters long and about three centimeters long, wherein the alternate design catheter is:
- (i) The alternative design of the basic catheter,
- (ii) The alternative design of the catheter with an S-shaped curve, or
- (iiii) The alternative design of the catheter with the flipped-tip,
A system for transradial access of the vasculature, which comprises, in combination:
- a plurality of specialty shaped and formed catheters;
- a grouping of compliant balloons, sheaths and wire tools;
- and
- wherein said catheter lengths are ranging between at least about 111 and 127 centimeters;
- having approximately 3.5 to 5.5 French diameters throughout.
A novel enhanced system for transradial cerebral access, as shown and described herein, and different from known systems, comprising in combination, at least a kit,
- further comprising:
- at least three sets of specialty catheters;
- a wire, sheath and introducer in predetermined size ranges, and methods for optimizing combination of catheters and said other tools.
A Modular Positioning System (MPS), as shown and described, further comprising, in combination:
- a board base;
- a grip bar;
- and
- a wrist pad.
A kit, comprising transradial access tools including a set of curve specific catheters, introducers and specialized wires.
A transradial access system, comprising, in combination:
- a non-transfemoral approach to neuro-endovascular procedures comprised of catheter assemblies ranging from at least about 111 to 127 cm's, with Fr sizes between at least about 3.2 to 5.9;
- a plurality of specialized curves emplaced within said catheter assemblies;
- specialized wires, sheaths and introducers.
