Embodiment Construction

[0037] Reference will now be made in detail to the preferred embodiments of the disclosed subject matter, an example of which is illustrated in the accompanying drawings. The disclosed subject matter is described below in conjunction with a detailed description of the system.

[0038] As disclosed herein, the devices and methods presented herein can be used to treat a variety of luminal systems of a patient. For purposes of illustration and not limitation, reference will be made to the cardiovascular system and blood vessels. In particular, the disclosed subject matter is particularly suitable for enabling the insertion of a catheter with an attached expandable member (such as a balloon or stent) coated with a therapeutic agent into the cardiovascular system of a patient, such as for performing angioplasty and treating delivery of agents to the vasculature. The disclosed subject matter enables catheterization while minimizing any loss of therapeutic agent or damage to the th...

Abstract

Introducer sheath for use in inserting a balloon catheter into a patient's vasculature includes a tubular member having an inner diameter, an outer diameter, a proximal end, a distal end, and a length therebetween, the inner diameter being sized to receive a catheter shaft having an attached expandable member in a deflated condition. The inner diameter can be varied from a first inner diameter at the proximal end and a second inner diameter at the distal end, the first inner diameter being greater than the second inner diameter. A method of inserting a balloon catheter into the vasculature of a patient is also disclosed. Additionally, a balloon catheter kit including a catheter and an introducer sheath is disclosed.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Application Serial No. 13 / 112,791, filed May 20, 2011, which is hereby incorporated by reference in its entirety. technical field [0003] The disclosed subject matter relates to a device to assist in inserting a catheter into an introducer sheath and a method of using the same. In particular, the disclosed subject matter relates to insertion aids for catheters having an expandable member (eg, a balloon or stent) located at a distal portion of the catheter, wherein the expandable member is coated with a therapeutic agent. Background technique [0004] Atherosclerosis is a syndrome that affects blood vessels in the arteries. It is characterized by a chronic inflammatory response in the arterial wall, mainly due to the accumulation of lipids, macrophages, foam cells, and plaque formation in the arterial wall. Atherosclerosis is often referred to as hardening of the arteries, altho...
