Pulsatile balloon catheter systems are provided. Aspects of the systems include: a pulse generator; and a balloon catheter assembly operably connected to the pulse generator. In embodiments, the balloon catheter assembly includes: a proximal connector operably connecting the balloon catheter assembly to the pulse generator and configured to transduce a first pulse energy generated by the pulse generator to a second pulse energy; a distal balloon; and a catheter component, where the catheter component includes a fluidic passage operably positioned between the proximal connector and the distal balloon, which passage is configured to propagate the second pulse energy from the proximal connector along the fluid passage to the distal balloon. Also provided are balloon catheter assemblies and kits that include the same. Also provided are systems and methods for assessing vessel compliance in-vivo. Also provided are systems and methods for determining system state of balloon catheter systems. The systems, assemblies and kits find use in a variety of different applications, including balloon angioplasty applications.

Systems and methods can involve wedge dissectors attached to strips in turn attached to medical balloons, for forming serrations within vascular wall tissue for angioplasty as well as drug delivery. Such balloon blowing techniques can reduce the balloon profile, the material costs, and the manufacturing time to build a serrated balloon catheter device. The design and process to build this type of balloon is described herein.

A catheter system includes a rolling membrane guiding catheter and a docking unit. The docking unit is configured to automatically insert a plurality of devices into the rolling membrane guiding catheter.

This invention discloses a pulse-release balloon dilation pump and method for intracranial arterial stenosis. Addressing the mechanical mechanism of thin intracranial arterial walls and irregular plaques leading to axial stress accumulation and subsequent complications such as dissection and detachment, this invention adds a pulse-release control unit to a conventional pressure pump. Its core physical principle is as follows: When the balloon dilates at an irregular plaque, the intramural strain energy density distribution is uneven. Static friction constraint keeps the system in a high-energy metastable state, and the accumulated elastic potential energy ΔU continuously increases with expansion. The constraint factor λ is defined as F_required / f_max; when λ>1, the balance is unstable, and energy suddenly bursts. This invention uses periodic short-term pressure release to instantaneously decrease the contact pressure, reduce the static friction limit, and briefly raise λ to >1, actively triggering micro-slippage, releasing a small portion of the accumulated energy each time, achieving segmented and gentle energy release. Pulse parameters (amplitude, frequency, etc.) can be flexibly adjusted according to actual clinical conditions. The pulse mode offers flexible and diverse usage options. Operators can initiate it synchronously in the early stages of dilation, when risk signs appear, intervene as needed during pressure application, or combine multiple methods, allowing the operator to independently determine the operational procedure. Based on thin-film mechanics, tribology, and viscoelasticity theories, this invention is simple to operate, does not alter the clinical procedure, and effectively reduces the risk of complications during intracranial artery stenosis balloon angioplasty.

A system includes a processor in communication with a memory. The processor is configured to receive one or more images of an implantable device within a vascular system; extract at least one image feature from the one or more images, the at least one image feature indicating the position of the implantable device relative to the vascular wall of the vascular system; and select at least one view based on the at least one image feature for optimal observation of a medical procedure involving the deployment of the implantable device to the vascular wall.
