Title: Laser catheter delivery system
IPC: A61B17/00
Filed: 1989-02-20
Abstract: Laser catheter delivery system for 
controlled ablation of atheroma, combining laser 
angioplasty and intra-arterial ultrasonic 
imaging. In laser ablation of atheroma dosage and 
directing of the laser light beam represent 
critical problems, since accurate removal of the 
atheroma is required without damaging of 
the arterial wall. The present system comprises a 
combined laser and ultrasound catheter composed of  
- means for emitting a laser beam in an artery (209) 
towards an atheroma (208) for ablation of the 
atheroma  
- optical fiber means (205) for feeding laser 
light from a laser to said emitting means,  
- an ultrasound transducer (201) for intra-arterial 
imaging of tissue structures like the 
atheroma (208), the vessel wall (209) and surrounding 
tissue, by emitting a pulsed ultrasound 
beam (202) towards said tissue structures and 
also arranged to receive backscattered 
ultrasound from said tissue structures  
- beam directing means (203, 206) arranged to direct 
the ultrasound beam (202) towards said tissue 
structures and also arranged so that 
the laser beam can be brought into for practical 
purposes any of the directions the ultrasound 
beam can assume for imaging, so that 
the laser beam (207) can be steered towards a portion 
of the ultrasound image indicating a 
portion of an atheroma (208) to ablate said portion of the atheroma  
- receive circuits adapted to receive and 
process the backscattered ultrasound for imaging of 
the tissue structures  
- means for analysing said ultrasound image, 
either manually or automatically, to determine 
the presence of atheroma so that said image 
can be used to direct the laser beam towards 
the regions in the ultrasound image which have 
been determined to represent a portion of 
an atheroma and determine the intensity 
and the dosage of the laser beam for accurate 
ablation of said portion of the atheroma.

Title: Wound dressing
IPC: A61F13/02
Filed: 1989-11-30
Abstract: A wound dressing comprises a vapor permeable plastic film (10) 
coated on one side with an adhesive (12) about the periphery of 
a wound contacting window (14) in the central portion of the 
dressing. A pair of release liners (16, 18) covers the adhesive 
coating and include (16', 18') tabs so that the release liners can be 
peeled from the adhesive coating. Means are provided adjacent 
to and at opposite lateral sides of the wound contacting window 
to change abruptly the resistance to peeling of the release 
liners from the adhesive coated film. Accordingly, when the 
user feels this change in resistance, he or she knows that the 
wound contacting window and a small portion of the adhesive 
about the periphery thereof is uncovered which allows the 
dressing to be anchored about the patient's wound with the 
release liners partially in place and the wound contacting 
window exposed. This minimizes the tendency of the film to 
wrinkle and/or to fold on itself such that the adhesive adheres 
to itself.

IPC: B32B27/20
Filed: 1990-04-07
Abstract: Bei Armaturenbrettern, die durch eine mehrschichtige 
mit PUR-Schaum hinterschäumte Folienanordnung gebil­
det sind, besteht die Gefahr, daß die Folien bei star­
ker Wärmeeinwirkung aufreißen, weil sich die PUR-­
Schaumschicht bei hohen Temperaturen zersetzt und die 
dabei entstehenden Zersetzungsprodukte in die Folie 
eingehen und dort die Zersetzung der Folie katalysie­
ren.  
     Um diesen Nachteil zu vermeiden, ist die Folienanord­
nung in neuartiger Weise so ausgebildet, daß zumin­
dest eine Folienschicht lichtreflektierendes Material 
bzw. Pulver oder Pigmente enthält, durch welche die 
Erwärmung der Folie infolge von Strahlungswärme re­
duziert wird.

Title: Expandable thermoplastic microspheres and a method for the production and use thereof
IPC: C09D7/65
Filed: 1991-10-28
Abstract: A method for producing expandable thermoplastic microspheres by polymerisation in a reaction vessel of an ethylenically unsaturated monomer or a mixture of monomers in an aqueous suspension in the presence of a condensed propellant. In the method, the monomer or monomer mixture is suspended in the aqueous medium in the presence of a powder stabiliser which consists of a salt or hydroxide of any of the metals Ca, Mg, Ba, Fe, Zn, Ni or Mn. The powder stabiliser is insoluble in the aqueous medium at the pH the aqueous medium has at the polymerisation. The aqueous medium may also contain a co-stabiliser. The method further comprises the step of washing off the powder stabiliser from the microspheres after the polymerisation by lowering the pH of the aqueous medium by the addition of acid. Alternatively, amphoteric hydroxides can also be dissolved by a pH increase. The invention also relates to microspheres produced according to the method of the invention, and to the use thereof.
