US Patent:

7431711, Oct 7, 2008
Filed:

Nov 21, 2002
Appl. No.:

10/302766
Inventors:

Timothy E. Moutafis - Gloucester MA, US
Edward J. Bromander - Tewksbury MA, US
Assignee:

HydroCision, Inc. - N. Billerica MA
International Classification:

A61B 17/20
US Classification:

604 22
Abstract:

Certain embodiments of the present invention provide a series of surgical instruments utilizing liquid jets for cutting, ablating, debriding, washing, etc. , tissues and/or other materials from the interior and/or exterior surface of the body of a patient. Certain embodiments of the surgical instruments provided according to the invention utilize a channel positioned adjacent to and downstream of a liquid jet-forming nozzle such that at least a portion of the passes at least one of within the channel and adjacent to and along the length of at least a portion of a longitudinally-oriented opening in the channel, when the instrument is in operation. The use of such channels in certain embodiments of the inventive surgical instruments can enable the instruments to provide enhanced control over the depth and degree of cutting and/or ablation of tissue; and/or can provide improved and enhanced functionality for cleaning, debriding, and/or trimming and cutting a tissue surface; and/or can provide longer effective liquid jet beam cutting/ablation lengths by reducing the degree of dispersion of the jet along its length.

International Classification:

B05C 3/00
A61F 2/06
A61F 2/00
US Classification:

118400, 118404, 623 115, 424423
Abstract:

A method, a kit, and an apparatus provide a coating on an implantable medical device. The apparatus includes housing, a sealed reservoir chamber disposed in the housing, a reducing template, and a reservoir access port. The sealed reservoir contains the coating material. The reducing template is sized to receive a medical device therethrough for application of the coating material. A seal breaching mechanism can be provided and adapted to breach the sealed reservoir upon activation of the apparatus. The reservoir access port, which is disposed in the housing, is adapted to fluidly couple the reducing template with the reservoir chamber upon activation of the apparatus for coating the medical device.

8529498, Sep 10, 2013
Filed:

Sep 9, 2008
Appl. No.:

12/207282
Inventors:

Timothy E. Moutafis - Gloucester MA, US
Edward J. Bromander - Tewksbury MA, US
Assignee:

Smith & Nephew, Inc. - London
International Classification:

A61M 1/00
US Classification:

604 35
Abstract:

Certain embodiments of the surgical instruments provided according to the invention utilize a channel positioned adjacent to and downstream of a liquid jet-forming nozzle such that at least a portion of the liquid jet passes at least one of within the channel and adjacent to and along the length of at least a portion of a longitudinally-oriented opening in the channel, when the instrument is in operation. The use of such channels in certain embodiments of the inventive surgical instruments can enable the instruments to provide enhanced control over the depth and degree of cutting and/or ablation of tissue; and/or can provide improved and enhanced functionality for cleaning, debriding, and/or trimming and cutting a tissue/surface; and/or can provide longer effective liquid jet beam cutting/ablation lengths by reducing the degree of dispersion of the jet along its length.

US Patent:

20040228736, Nov 18, 2004
Filed:

Jan 13, 2004
Appl. No.:

10/756801
Inventors:

Timothy Moutafis - Gloucester MA, US
Edward Bromander - Tewksbury MA, US
International Classification:

F04B001/00
US Classification:

417/053000
Abstract:

Apparatus and methods of their use are described for engaging a pumping cartridge with a pump drive. In certain embodiments, the cartridge, comprising a cylinder and a movable piston assembly, is initially assembled or subsequently positioned so that the distance between the attachment point on the piston assembly for coupling to a drive assembly, and a reference point on the cylinder, is greater than the maximal distance that will be encountered during normal oscillation of the piston during use. The cartridge, in certain embodiments may be pressed into a drive assembly having means for immobilizing the cartridge and means for coupling the piston assembly to the driveshaft. In certain embodiments, when the cartridge is fully inserted into the drive assembly, the piston is pressed into the cylinder sufficiently to establish a selected distance so that the piston shaft is in the proper position to engage with a coupling mechanism carried on the driveshaft.

A61L 33/00
B05C 11/02
US Classification:

427 21, 118712
Abstract:

An apparatus and a method for applying a coating to a medical device such as a stent, balloon, or catheter, shortly before insertion or implantation are described. The apparatus and method produce uniform consistent coverage of the medical device in a predictable, repeatable and controllable manner and reduce the need for preservative components in the coating or for excessive curing or hardening of the coating.
