Filed:

Sep 4, 2012

Appl. No.:

13/602747

Inventors:

Robert C. Farnan - River Vale NJ, US
Arielle Drummond - Saddle Brook NJ, US
Jerry Brightbill - Newton MA, US
Timothy Walter Robinson - Sandown NH, US
Richard Wisdom - Mattapan MA, US
Jonathan O'Keefe - North Attleboro MA, US

Assignee:

CIRCULITE, INC. - Saddle Brook NJ

International Classification:

A61B 17/11

US Classification:

606153

Abstract:

A surgical cannula system. The surgical cannula system includes a cannula having a proximal end, a distal end, and a lumen extending therebetween. A tissue attachment ring, being configured to be coupled to a biological tissue, includes a lumen extending therethrough. A locking mechanism has a first locking state, in which the cannula is configured to move with respect to the tissue attachment ring, and a second locking state, in which movement of the cannula with respect to the tissue attachment ring is resisted.

International Classification:

A61F 2/88
A61F 2/90

Abstract:

An endovascular medical device that, when inserted into a vessel having one or more dilations and one or more narrowings in close proximity, redefines the vessel opening (lumen) along the longitudinal axis of the device, separates that lumen from the excess dilated volume within the dilation, and props open the lumen within the narrowing. The device is constructed in a manner to alter the hemodynamics at the interface between the redefined lumen and excess dilated volume, to facilitate the healing process within the dilated vessel. The device is constructed in a manner to provide sufficient radial force to open a narrowed portion of the vessel, to facilitate flow through the vessel. The device is constructed substantially from bioresorbable materials so as to eventually allow for the return of normal vasomechanics and cyclic wall stresses.

Abstract:

Methods for treating hydrocephalus using a shunt, the shunt having one or more CSF intake openings in a distal portion, a valve disposed in a proximal portion of the shunt, and a lumen extending between the one or more CSF intake openings and the valve, the method comprises deploying the shunt in a body of a patient so that the distal portion of the shunt is at least partially disposed within a CP angle cistern, a body of the shunt is at least partially disposed within an IPS of the patient, and the proximal portion of the shunt is at least partially disposed within or proximate to a JV of the patient, wherein, after deployment of the shunt, CSF flows from the CP angle cistern to the JV via the shunt lumen at a flow rate in a range of 5 ml per hour to 15 ml per hour.
