A stent delivery catheter and method for making the same includes a tubular balloon, an elastic sleeve, and a stent. The balloon is mounted around a catheter shaft, and the stent is crimped onto the balloon. The elastic sleeve is positioned between the balloon and the stent, the sleeve extending beyond the ends of the stent where the ends of the sleeve are fixed to the catheter shaft. Sleeve material is gathered and folded over the ends of the stent to retain the stent snugly against the balloon during delivery.

A stent delivery catheter includes an extendable shaft portion, a tubular balloon mounted thereon, a stent and a pair of elastic retaining caps. The balloon is mounted onto the catheter at a mounted length that is shorter than the formed length of the balloon to generate excess balloon material which is gathered into circumferential folds. The extendable portion of the catheter shaft elongates in response to tension applied by the balloon as the folds open during inflation. Elongation of the catheter shaft drives the retaining caps apart to uncover the ends of the stent.

The invention is an intraluminal therapy catheter having a least two treatment members disposed near the distal end of the catheter, the members being independently inflatable to perform angioplasty and/or fluid-sourced brachytherapy. A first treatment member is helically mounted about the shaft of the catheter, and forms a helical perfusion channel when inflated into contact with the vessel being treated. In a first embodiment of the invention, the second treatment member is also helically mounted about the catheter shaft and capable of forming a helical perfusion channel when inflated into contact with the vessel. The first and second treatment members are intertwined to form a double helix configuration wherein each member is capable of being inflated to generally fill the helical perfusion channel created by simultaneous inflation of the other member. In a second embodiment of the invention, the second treatment member is a tubular balloon mounted generally coaxially about the catheter shaft, adjacent to the first treatment member.

An over-the-wire catheter provides substantially shadow-free delivery of radiation to a body lumen by having a treatment region wherein a guidewire tube and a radiation source tube form a parallel double helix configuration. When a radiation source is inserted into the radiation source tube and a guidewire is present in the guidewire tube, no portion of the treatment site will be obscured from all radiation emitted by the radiation source because, within the treatment region, the guidewire and the radiation source are not in a conventional, axially parallel configuration. Optionally, a balloon may be mounted about or adjacent the treatment region of the catheter, the balloon providing centering and/or dilatation functions.

An exclusion stent includes a proximal anchor and distal anchor for anchoring the exclusion stent within a parent vessel. A center mesh is connected to and extends between the proximal anchor and the distal anchor. During use, the exclusion stent is deployed such that the center mesh extends across an aneurysm. The center mesh restricts blood flow to the aneurysm. However, the center mesh does not completely block blood flow, thus insuring blood flow to perforators of the parent vessel.

An ETV procedure includes forming a burr hole in a human skull; passing an endoscopic third ventriculostomy (ETV) probe through the burr hole; fenestrating the floor of the third ventricle with the ETV probe to form an opening in the floor; and measuring a flow of cerebrospinal fluid (CSF) with a flow sensor of the ETV probe. The ETV procedure further includes deploying a membrane eyelet into the opening; and measuring a flow of CSF through the opening with a flow sensor of the membrane eyelet.

An irritant or polymer is dispensed to the inner surface area of an aneurysm to exert a contractile force on the inner surface area of the aneurysm, thereby shrinking the aneurysm. As a result, the artery wall at the aneurysm site is strengthened, the risk of rupture is decreased, and at least a partial cure for the expansion of the arterial wall at the aneurysm site is provided.

A structure and method for deploying an eyelet in a membrane, where the eyelet includes: a waist section; a first anchor section coupled to and flared from the waist section; and a second anchor section coupled to and flared from the waist section. The eyelet is deployed such that the waist section is located within a membrane opening of the membrane thus keeping the membrane opening open. Further, the membrane is sandwiched between the first and second anchor sections thus anchoring the eyelet to the membrane.
