International Classification:

A61B 17/10

US Classification:

606142, 606205

Abstract:

An instrument for reconfiguring stomach tissue includes a sealing member that seals a section of a tissue manipulator from contact with bodily fluids. The tissue manipulator includes a first portion that is configured for releasable coupling to an actuating member and a second portion configured to receive an implant to be deployed within the patient. The tissue manipulator also includes a rectangular member and a cavity for receiving a coupler of the actuating member. The tissue manipulator has a first member with tissue penetrating elements and a second member with engaging elements configured to deflect the tissue penetrating elements upon relative movement of the first and second members. The actuating member includes a tissue penetrating element support positioned to limit bending of the tissue manipulator. The instrument includes an actuating mechanism that is configured to move at least one of the first and second members of the tissue manipulator.

Abstract:

A system for performing a medical procedure comprises a first assembly and a second assembly. The first assembly comprises an articulating probe assembly and a first housing. The articulating probe assembly comprises an outer probe and an inner probe. The outer probe comprises: multiple articulating outer links and a first connector. The inner probe comprises multiple articulating inner links and a second connector. The first housing comprises: a proximal portion; a distal portion; and an opening positioned in the first housing distal portion. The articulating probe is constructed and arranged to pass through the first housing opening. The second assembly comprises: a first carriage constructed and arranged to operably engage the first connector of the outer probe; a second carriage constructed and arranged to operably engage the second connector of the inner probe; a dual linear drive assembly configured to independently translate the first carriage and the second carriage; and a second housing comprising a proximal portion and a distal portion. The first assembly is constructed and arranged to operably attach to the second assembly. Methods of performing a medical procedure are also described.

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.
