Abstract
A method of providing a channel filled with aqueous gel in soft tissue comprises injecting a biocompatible aqueous gel into the tissue. Also disclosed is a corresponding device, the combination of the device and a guide for its insertion into tissue, and a system comprising the combination and a reservoir filled with aqueous gel comprising means for exerting pressure on the gel.
Claims29
A method of defining a channel filled with aqueous gel in soft tissue using a device that comprises an oblong rotationally symmetric pin comprising a distal section extending from the distal towards the proximal end, a central section extending from the distal section towards the proximal end, and a proximal section extending from the central section to the proximal end, a central conduit extending from the proximal end to the distal section, the central conduit providing fluid connection between a reservoir for aqueous gel, and lateral passages extending radially from the central conduit disposed in the central section, the method comprising:
- inserting the device into the soft tissue;
- supplying the aqueous gel to the central conduit from the reservoir during insertion and/or upon insertion of the device;
- pressing out the aqueous gel from the passages;
- and
- withdrawing the device from the tissue while leaving the aqueous gel in the channel that is formed in the soft tissue by the device to define the channel filled with the aqueous gel.
A system configured for forming an aqueous-gel-filled channel in soft tissue comprising:
- an oblong rotationally symmetric pin comprising a distal section extending from a distal end towards a proximal end, a central section extending from the distal section towards the proximal end, and a proximal section extending from the central section to the proximal end, a central conduit extending from the proximal end to the distal section, and through bores disposed in the central section radially extending from the central conduit;
- a reservoir that stores aqueous gel;
- and
- a fluid connection between the conduit and the reservoir
