July 28, 2014



By a News Reporter-Staff News Editor at Biotech Business Week -- According to news reporting originating from Alexandria, Virginia, by NewsRx journalists, a patent by the inventors Suon, Naroun (Lawrence, MA); Bacon, Dan (Fitchburg, MA); Nam, Ra (Lawrence, MA); Smith, Paul (Smithfield, RI); Golden, John (Norton, MA); Weitzner, Barry (Acton, MA); Kappel, Gary (Acton, MA), filed on January 27, 2012, was published online on July 15, 2014 (see also Boston Scientific Scimed, Inc.).

The assignee for this patent, patent number 8777898, is Boston Scientific Scimed, Inc. (Maple Grove, MN).

Reporters obtained the following quote from the background information supplied by the inventors: "Minimally invasive surgical tools, such as endoscopic and laparoscopic devices, can provide access to surgical sites while minimizing patient trauma. Although the growing capabilities of such therapeutic devices allow physicians to perform an increasing variety of surgeries, further refinements are needed to reduce costs associated with such procedures.

"Some minimally invasive systems include surgical devices that may be sterilized for reuse. Such devices are usually expensive to manufacture and must be designed to withstand multiple sterilization procedures. Similar disposable devices often have limited performance due to the use of cheaper materials and low-cost manufacturing techniques."

In addition to obtaining background information on this patent, NewsRx editors also obtained the inventors' summary information for this patent: "The medical devices described herein overcome at least some of the limitations of the prior art. One aim of at least certain embodiments of the present invention is to reduce costs by providing a medical device that can include some reusable and some disposable components. For example, a medical device could include a reusable handle and a disposable catheter. The reusable handle could be adapted for use with different types of catheters having different end-effectors.

"One aspect of the invention is directed to a medical device having a longitudinal axis, and including a handle and a catheter. The handle can include a body having a proximal end and a distal end, an actuator moveably coupled to the body, and a handle control member coupled to the actuator, wherein the actuator can be configured to move relative to the body to move the handle control member. The catheter can include a shaft having a proximal end and a distal end, wherein the proximal end of the shaft and the distal end of the body can be configured for releasable coupling. The catheter can also include a steering section located along the shaft and a catheter control member coupled to the steering section, wherein the catheter control member can be configured to move relative to the shaft to move the steering section relative to the longitudinal axis. The medical device can also include a securing member configured to move relative to at least one of the handle and the catheter to releasably couple the handle control member to the catheter control member.

"According to another aspect, the invention can include a handle configured to releasably couple to a catheter. The handle can include a body configured to releasably couple to the catheter, an actuator moveably coupled to the body and configured to engage a user's hand, and a plurality of handle control members coupled to the actuator, wherein the actuator can be configured to move relative to the body to move at least one of the plurality of handle control members. The handle can also include a securing member configured to move relative to the handle to releasably couple the plurality of handle control members to a plurality of catheter control members.

"According to another aspect, the invention can include a catheter configured to releasably couple to a handle. The catheter can include a shaft configured to releasably couple to the handle, a steering section located along the shaft, and a plurality of catheter control members coupled to the steering section, wherein each of the plurality of catheter control members can include a first attachment member and can be configured to move relative to the shaft to move the steering section. The catheter can also include a lumen configured to at least partially maintain coupling between the first attachment member and a corresponding attachment member located on a handle control member.

"According to another aspect, the invention can include a method of assembling a medical device. The method can include moving a handle having a handle control member relative to a catheter having a catheter control member in untensioned state, to engage the handle control member with the catheter control member. The method can also include moving a securing member from a first position to a second position to tension the catheter control member and couple the handle control member to the catheter control member.

"Additional objects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims.

"It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed."
