摘要:
A stent delivery system for placing a stent within a vessel of a human body. The stent delivery system includes an elongated tube that extends for most of the length of the stent delivery system and is attached to a distal end of a proximal section of an inflatable balloon. A stent is then co-axially mounted on the inflatable balloon. A front section of the stent delivery system includes a small angle cone having a lubricious outer surface. The front section is then attached to a cylindrical distal portion of the balloon and has an outside diameter at the proximal end of the small angled cone which is approximately the same diameter as the outer diameter of the stent. A core wire extends within the inflatable balloon and further into the front section of the stent delivery system.
摘要:
An introducer sheath for placement into the vascular system of a human subject. The introducer sheath has a tubular shaft, a side arm, and a hemostasis valve with an integrated attachment mechanism for attaching and detaching a proximal end of the introducer sheath to and from the skin of the human subject.

Disclosed are methods for detecting an acute myocardial infarction (i.e., a heart attack) at the earliest possible time and promptly warning the patient that he should immediately seek medical care. The present invention includes an implantable electronic system that can sense a change in the patient's electrogram that is indicative of a heart attack. If a heart attack is sensed, the device would then cause an implantable and/or externally located alarm to be actuated to warn the patient of his condition and a medical practitioner at a remote diagnostic center would receive the patient's electrogram for analysis. The patient or a caretaker would then be informed to self-inject medication through a subcutaneous, pass-through drug port that can be a separate device or integrated into the implanted device that is designed for the early detection of a heart attack. The methods of the present invention include determining if a human patient is likely to have a heart attack and, if he is, then implanting within that patient a device that can sense when a heart attack occurs and alarm the patient to take appropriate actions if a heart attack does occur.
